Hi,

Anybody know what this error means? I sometimes see it next to "PPPoE Connection" under WAN when logging into my 7402 when it's trying to connect to my ISP. I usually have to reset the router to get it to connect properly.

Sorry, no idea here. Because so far (~1.5 yrs) I only encountered it once ...

Wow, this happens ALL the time to me, at least 4 times a day. I need to reset my modem to get it to reconnect and then im back on the net surfing fine. I have a Billion 7402G setup to connect thru PPPoA (also happens thru oE)

I tested the modem at a friends house and the 3 days he had it it never did it once

This problem is driving me insane, when it happens I lose PPP connection each time and cant access the net. Everytime it happens i need to reset my router to get back on the net. I am running the latest firmware 5.03, if anyone could please help me, i would be very thankful.

No one seems to know what the hell the problem is and its got me so frustrated its beyond belief. I cant understand why the modem works fine at a friends (on the same ISP) and totally craps out at my house. When i am connected, the modem is fine, however, dropping PPP randomly 4 times a day drives me insane.

Please, help me, for the love of god, I will be eternally in your debt.

Might be some conflict in your setup as it works on another computer.

Make sure your dialup modem is set to 'never dial a connection' (or disable it) and have your connection 'obtain an IP address automatically' and same with 'DNS server address'.

I'm no expert (so I may be way off the mark... won't hurt to try tho:)

If nothing else it bumps the thread and someone else may have a thought.
Good luck

I am getting an IPCP error with my Billion 7402VGO (using iiNET). Happens when it tries to log in the first couple of times after a modem reset. Eventually it logs on.

Anyone have further thoughts as to what the problem is?

I'm getting the same problem now! I'm with iinet and my exchange was recently upgraded. I have a Billion 7402G

im getting this too now, 7402vl. line drops out, i check status, see ipcp error, takes a while to login. happening 2-4 times a day atm. on iinet, adsl2+. have reasonable line figures, using pppoa....

digging this thread up again. Since having been migrated to an iinet dslam i'm getting these errors a few times a day too. the modem is a 7402g. does anyone know what these errors are? normally it reconnects automatically for me but when it happens is seemingly random. up until now i'd had great stability.

I have just started seeing this error too.

modem: BiPAC 7402VGP, 5.04i firmware
ISP: iiNet with iiPhone, just updated to ADSL2+

The problem seems to have started when I up'd the speed through iiNet's new Speed Manager last night. The router connects fine for a while, say 15-20 minutes, then drops out for 5-10minutes.

I'm experiencing the problem this morning - iinet customer on killara exchange:

BiPAC 7402VGP running 5.04c.dg1

when it's reconnecting, I sometimes see "Incorrect IPCP configuration" briefly before the reconnect.

net's lasting for ~5 mins before dropping. it's done this about 5 times now, but it's the first time I've experienced such a thing. just powercycled the router, hopefully the issue's @ iinet's end and will be rectified soon!

just dropped again :/

I am suffering this as well...

I am on one of internode's 24mb exchanges; I too get this "Incorrect IPCP configuration" intermittently but sometimes continually. Out of desperation I am searching far and wide for a resolution.

Wouldn't be funny if, ever since I upgraded to Internode’s dedicated hardware (their ADSL2 plans) an incompatibility between their backend hardware and the Billion 7402 (5.03 firmware) has crept into the mix.

The node have recommended that I get a central line splitter installed but if it’s a hardware incompatibility problem I wonder if that will really work.

Has anyone worked this out....

IPCP stands for the PPP Internet Protocol Control Protocol. You can find the gory details in RFC 1332.

The IP Control Protocol (IPCP) is responsible for configuring, enabling, and disabling the IP protocol modules on both ends of the point-to-point link. IPCP uses the same packet exchange mechanism as the Link Control Protocol (LCP). IPCP packets may not be exchanged until PPP has reached the Network-Layer Protocol phase. IPCP packets received before this phase is reached should be silently discarded.

So, it's not a hardware issue, but more like a router firmware issue (or an incompatibility with the other end of the PPP link).

I'm also seeing this problem - we're running 7402R2's with the current firmware. They are connected to the firewall device which is then connected to a medium sized LAN and a DMZ. It will drop the connection to the outside world and show the error "Incorrect IPCP configuration" and then be offline for 1-2 mins before reconnecting to iinet.

what f/w

I'm getting this error after changing the Coding Gain to 7. It happened once then re-connect.

same error to me

maybe fw 5.07 solve it?

wow guys
does anybody have this problem ?

I get this error from time to time. Internode ADSL2 5.07 firmware on 7402GL

I get this too occassionally, 7402GL FW 5.08 Beta, usually after it drops sync and tries to reconnect the first time. Not really an issue for me but.

I get the same thing, sometimes once a week, today, about three times.
7402VGO on an Internode DSLAM, drops the connection, reconnects, gets the error, drops the connection again, then reconnects fine.

EDIT: only using firmware 5.04i, never had a problem so didn't keep up with the updates. Just reading the release notes now to see if it's worth updating.

-Nick

I think it's a firmware problem about authentication chap/pap with the remote server
i use firmware 5.06 .

I'm on firmware 5.07 on a 7401VGP and have seen this a few times, but usually, within a few minutes of me seeing it, it has connected properly.

Yeah, now that Uni exams are pretty much all over (6 prac exams on Monday, but should be right with them), I'll have some time to finally sort all this kinda stuff out (after moving back in here).

-Nick

now i try to use coding not on auto but set to a specific value...
I hope to solve.

Anyone work this out? I get this every now and then, and have been having it every 10-20 minutes this evening. I have a BIPAC-7402 running firmware 5.07

I started getting this problem about three days ago, after 18 months of no problems, and it was annoying as hell. Solution, I updated the firmware to 5.07, reset to factory configuration, then redid the settings manually. I no longer have this error happening, now.

I'm having this problem tonight after upgrading my 7402G to firmware 5.07 (was running 5.05 which was stable, but had a problem with Mac OS X being unable to connect using WPA2, which was supposed to be fixed in 5.07... it wasn't.)

I'm getting small patches of uptime (this is one of them) so I'm going to try downgrading to 5.05 to see if it works.

Shame the WPA2 thing wasn't fixed either. When I try to connect under WPA2, the computer reports that the router has an access control list in effect (it doesn't). Under WPA1, it says the password is wrong (it isn't). WEP works fine.

Hmm... on second thoughts, we just had a one-second long brownout (power outage due to high demand) which is probably due to high airconditioner use in Sydney today -- so I wonder if we've had a few brownouts this evening that were so brief that they didn't affect lights etc, but did affect the modem.

I'm having this problem tonight after upgrading my 7402G to firmware 5.07

I had serious uptime problems as well due to the IPCP config error.

I contacted Billion support and got firmware 5.52c for my 7402G and now have 24 hours uptime (not one drop)...It seems to have fixed it so far! I'll hold judgment for another week or two though. If anyone has a 7402G and wants to try the firmware Whim me.

I have had the same problem with my 7401 VGPM. Just upgraded to 5.52d and it has been ok so far.

I'm getting this error as well with my 7402G, and I think it started happening only a few weeks ago. I get it approximately every 24-36 hours - sometimes it'll stay connected longer - and it's very annoying. I usually reset the router and then it reconnects.

I'm running the latest firmware version, so any suggestions about what this actually means and what causes it would be appreciated. From the above posts it seems to be a fairly common problem.

7402VGP on iiSLAM N/Syd exchange.

I used to get this problem semi-regularly also. About once a week or fortnight it would go thru a cycle of connect/disconnect (staying online for a minute or so at a time) and giving that IPCP error.

I suspected it was the iiSLAM but could never prove it and never got any feedback from iinet support about my reports (not that i realistically expected any).

Havent noticed it for quite a while now, and I did add a central splitter some months ago, but I couldnt say whether there was a correlation.

On at least one occasion i narrowed it down to a noisy electrical device being switched on (a cheapass power supply on an external HDD) - each time it would go on the modem would go 'click' and just loop the connect/disconnect cycle with the IPCP error. I could repeat this whenever i liked just by switching it on. Interestingly it doesnt do it anymore tho - which may be the splitter, who knows cant remember when it stopped.

Has any1 discovered how to fix this error yet?

I'm using the billiong vgpm-7404M and im getting the incorrect ipcp configuration every few minutes, and it's getting really annoying. im on a kern ADSL2+

is this an error only for billion modems?
becoz this error comes up every 1hr or so, it's not like i'm having adsl, but dial up.

Yes as far as I know it's only something on Billion modems - there's been some discussion regarding it on the Billion forums where an admin suggested PPPoA / PAP as being something that could resolve it, however that's what I'm already running so I don't think that's the root cause. Right now the the 7402x series has a lot of firmware problems with the latest 5.52, and a beta was released on Friday (although it still doesn't resolve many of the issues that people are having), but it's a step in the right direction.

If you're having the same problem it might be a good idea to sign up to the Billion forums and bring it to their attention over there so that more discussion can be held with the admins who are involved with the firmware development - maybe that will get more attention brought to the issue and then hopefully a resolution.

Either way the forums over there provide good information, particularly regarding the latest firmware and its associated problems (if you're not currently running 5.52* then be aware that once you upgrade to it you need to use the emergency recovery tool to downgrade again, which is an annoying process and one that can't be done through the web admin interface). Other users have also mentioned this problem in the current beta firmware thread, so the more people that go over there and voice the problems they're having with it, the more likely something will be done about it.

mind sharing the website to the official Billion forum?

www.billion.com.au/forums

The forum you're after is probably Firmware -> Firmware, where there's currently discussion about this error in the sticky topic "New Firmware for 6404V(G)P & 740x Series - 5.52e (Beta)".

Have/had same error on my 7402VGP after upgrade to the latest release (at work so can't remember release number) but it seems to have something to do with the modem initially acquiring an IP address from my ISP (Optus DSLAM).

After the router logs on and sync/IP obtained, the error disappears.

Quentin, is their an answer to this, as I have not experienced this before in over 2 years of owning the router, so it must be firmware bug related.

Hi PikeЯ™

Please try changing to PPPoA / PAP, this is currently being investigated by Engineers.

Cheers

Thanks Quentin for you reply, ATM router is still up and been running fine for a day or so now, so no big problem, but would be great to know what has caused this in the new firmware.

Cheers

I just started getting this as well the last week on 5.52E so I upgraded to 5.52F and its still happening. (yes I reset it factory defaults). My sync speed has dropped dramatically too. Has something been rolled out at various exchanges lately to cause this? Any info appreciated. I'm with TPG ADSL2+

Billion BIPAC 7402R2-M with firmware 5.07 worked perfectly if not to count that they never re-authenticate PPP if the authentication is dropped with ADSL sync staying on the line. Billion support gave us their standard no-brainer excuse: "upgrade the firmware to the last version". Upgrades to 5.52d never worked with us (we are an ISP) giving "IPCP configuration error".

Later we found what the problem was. The modem/router tried to use only CHAP authentication while our routers accept only PAP. So this one proved to be easily resolvable by changing PPP auth method from CHAP (auto) to PAP.

Another problem with 7402R2-Ms is that we can't upgrade them from factory 5.52e to 5.52f, it's giving wrong annex type firmware version error message, tried with both Annex-M and Annex-A 5.52f firmware. Emergency downgrade doesn't work with these models for the same reason as well. So there's definitely something wrong with these new 7402R2-M supplies, the old ones were ok.

I get the "Incorrect IPCP configuration" error once a month perhaps. I dont really notice it as it reconnects automatically. So far in the 4 months Ive had the 7401VGP it has only happened in the last 2 months when I switched to ADSL2+ with iinet.

Never happened before.

Running latest firmware , 5.52g on PPOA, PAP.

Wierd. But hasn't caused a my downstream/upstream speeds to change.

Would like it not to happen though it is annoying at times.

Just thought I would add my experience to the thread.

I get that every time when reconnecting with PPPoE, try PPPoA

I have been having this problem for about 24 hours. The error appears every 15-16 minutes without fail. After restoring factory settings, updating to the latest firmware (5.52h1) changing ADSL2 profile and having the problem persist I came across this discussion.
I am now trying PPPoA as opposed to PPPoE. I will report the outcome.

EDIT: PPPoA did not fix the problem, I will now try using PAP as opposed to CHAP.

EDIT: The problem persisted after changing the authentication to PAP. I will attempt to use both PPPoA and PAP at the same time, and see if that changes anything.

EDIT: The problem still occurs. Any help with this would be greatly appreciated.

i also getting this error now using the latest firmware

i only owned a 7401VGPM for a month now

hopefully it gets fixed

I've started getting this again with the latest firmware as well - it went away with the previous firmware, and now it's back again. Argh.

i've been getting this error also on my 7404VGP. Any help would be great :)

Try changing to PPPoA / PAP.

Which provider do you have?

Cheers

hi Quentin,
yes i have the latest upgrade.

I haven't had the problem at all today or tonight. if it does it again i'll change to ppoa/pap.

I'm with spin.net ISP
Cheers.

I'm glad it's not just me with the dropout then IPCP problem.

I never had this happen on 1.5mb, only since I've changed to 8mb.

Anyone recommend a good replacement wireless modem/router?

Unfortunately I seem to have fallen victim to this problem. I am running a 7404VGO -A
with 5.52e firmware, which has been running with very few problems for months.

about 1-2 weeks ago this started happening out of the blue, around once every 24 hours. A simple soft restart fixes it (power button restart also works).

I have tried PPOE, PPOA PAP CHAP in various combinations with no success.
I am on Internode ADSL1, with the only recent change being a plan upgrade (extra quota, not speed)

I have been contemplating putting the newst firmware on for a while, but just haven't had time to re-key settings.

reading this thread seems to indicate the Billion has a bug, so hopefully firmware will fix it.

Very annoying and random problem though : (

Billion 7402GL
Firmware: 5.52h1

ADSL2+ - Adam Internet
Lots of drop-outs.
Lots of 'Incorrect IPCP Configuration' errors.

Prefer dial-up really compared to this.

Im now getting this problem as well. Never had it on previous firmware upgrades, only on this one i.e 5.52h1.

Im with Amnet, and im now getting this "Incorrect IPCP configuration" atleast 3-4 times a day.

Any one figured out if its a firmware issue?

I have the 7401-VGPM model.

Thanks

I just started getting this today for the first time ever, modem has been installed for well over 6 months, no firmware changes have been made. Just started occurring out of the blue this morning. Have had the connection drop out about 10 times already, and can see the incorrect IPCP message appear each time.

I'm using the billion 7402G here at work on internode. I'm hoping that it's just issues with the network this morning rather than an ongoing thing.....

The fact that it has suddenly started happening without any changes suggests a line / network issue.

Cheers

It seems to just be a wireless issue. I never get the line dropout & IPCP when connected via ethernet.

I forgot to ask. Has a fixed been worked out yet? I can't run a network cable to my pc from the router, without running across floor.. (rent house).

Can someone recommend a replacement modem?

HiPritch

Please elaborate on your problem, "incorrect IPCP" & line dropouts have nothing to do with wireless, this is an ADSL issue.

Cheers

sometimes the l2tp tunnel from the dslam (or wholesalers l2f) to your isp's equipment will stay up even though your session is down.

most isp configurations wont allow multiple logins for the same user/mac address, so you get a tunnel build failure resulting in errors ranging from an ipcp error to timeout waiting for pado packets.

sometimes, a reboot of your modem is enough for the stuck tunnel to dislodge, other times it can take leaving your modem off for 20+ minutes. there are cases where you'll need to call your isp to get your session cleared.

other causes are misconfiguration caused by multihopping of a l2tp session and not renegotiating lcp, resulting in a duplicate magic number and the tunnel failing to establish properly.

Hi Folks, same problem happening to me. REALLY annoying as it means my all important VOIP is not working. Here is the email I was going to write before I found this thread. I need to post it quickly before I drop out...

I have a Billion 6404VGP, running the latest h1 firmware. After a short time of being connected (20mins - 1hr), the PPP connection drops out with an audible click. The only way to get it back up again is to do a factory defualt reset and turn it off and back on again. After droping out, the PPpoE connection status says: 'Incorrect IPCP configuration'
Does anyone have any ideas that I could try?

More detail:
I recently had it repaired, as it was doing funny things with the PSTN line (staying off hook even when it shouldn't have been). As a result, they replaced the circuit board. They also upgraded it to the latest firmware (h1), which I didn't have before. It hasn't seemed 'right' since. However, the problem described above didn't start until a couple of weeks after I got the router back from the repairer.

I am with Exetel ADSL1 and am running through a Billion 5102s modem on bridge mode. I'm at Orange exchange (NSW) running off a RIM box.

I have a Billion 6404VGP, running the latest h1 firmware. After a short time of being connected (20mins - 1hr), the PPP connection drops out with an audible click. The only way to get it back up again is to do a factory defualt reset and turn it off and back on again. After droping out, the PPpoE connection status says: 'Incorrect IPCP configuration'

Hi

Have you checked this out with your provider?

Change encapsulation to PPPoA (Quickstart page) & authentication protocol to PAP (config -->WAN -->ISP -->Edit).

Cheers

My setup comprises a Billion 6404VGP connected to a 900MHz Canopy Subscriber Module with 11-element vertical-polarised yagi, and an Internode wireless broadband tower about 2km away.

Starting about 2 months ago I began to experience similar symptoms to those described above - intermittent and sometimes very frequent disconnects, with the message "incorrect IPCP configuration".

After reading various blogs, I flashed firmware V5.52h1, reprogrammed router etc etc all to no avail. Then I bypassed the router and logged directly into the radio module, where I was able to monitor the received signal strength. I was surprised to see that the signal was wandering all over the place (varying by 10 to 15 dB). Unsurprisingly, when the received signal dropped to very low (less than about -85dBm), the module lost sync, which presumably is when the router also dropped out (loud click and PPP light went out) and displayed the incorrect IPCP configuration message.

I raised the radio module and antenna from 9 to about 12 metres (presumably above tree branches causing problems on line-of-sight to the broadband tower), the received signal improved 15 to 20dB, and was very stable. Since then (a month ago), I have had only one drop out, on a very wet and windy day.

The link was the problem, and the router was OK all along! I hope this helps somebody.

I seem to have the same prob as a few others.

Yesterday the Billion 7404VGP started to disconnect every minute, today it was every 15minutes. Then it went to about every two hours and now its back to every couple minutes.

It loses synch, tries to reconnect and says its has an incorrect IPCP config. It reconnects a couple minutes later

Enscap is PPPoE and auth prot is chap.

I haven't updated the firmware since I got it(18 months ago). Just tried to do it but am getting an error message telling me the firmware is not for my hardware. I got the firmware from here billion.com.au/support/bipac7404vgp.php and tried both the one from the 18/9/07 and the 12/07/07

Hi

As per above suugestions change to PPPoA / PAP.

What is the filename of the firmware you downloaded & what does it say next to hardware version on status page?

Cheers

Well I tried those 2 i mentioned but it looks like i downloaded the annex A. I have just upgraded to 552h1.

I should change those settings to PPPoA even though the ISP says to use the ones I currently have? It wont matter?

This is a nightmare. Ive got the latest firmware now and have tried the PPPoE and the PPPoA. This is the result

Do you have ADSL or ADSL2+?

What are router's current attenuation / snr figures?

Cheers

I appreciate your efforts.

I sent an email to IInet when I made the first post couple of days back. Havent heard back yet. Standard.

Its ADSL2+. Not sure where I find those numbers but I'm 950m from the exchange, pretty much on the same street. I normally download at a max of 1.3meg.

I went and bought a new modem/router today and thought i would check the Billion before I switched them over. I have been connected for 7+hrs. Will see how i go overnight.

The Billion comes out of warranty in about 5 days so would love to sort it out before then.

slamdunka writes...

On the browser "Status" page for the router, the easy way is to click the blue 'ADSL' link in the 'Port Status' section. The other way is the menu options Congfiguration->WAN->ADSL.

The resultant page has your line sync and connection mode.
Then click 'Advanced Options' to see your SNR Margin, Line Attenuation, and CRC Errors.

Or install the brilliant SNMP viewer - www.billion.com.au/downl...iewer_100_57.zip

Only went out a couple of times over the weekend but back to disconnecting alot today, including when the phone rings. This has never happened before and I have the required filters in place.

The SNR Margin is 10.0 dB down and the same up.
The Line Att is 25.0 dB down and 17.5 up.
CRC Errors are zero.

This is with it set PPPoE/PAP

I havent heard back from IInet.

Looks like I'm another sucker with this error message as well. I'm lucky to be getting 5-10mins before it drops out. I've got it set to PPPoA and PAP, still hasn't helped.

Generally the internet drops out, after about 30 secs the status page will come up with "incorrect IPCP configuration", then sometimes the PPP connection line has "xDSL not syncronised"

Below are the SNR
SNR Margin 16.5 dB 17 dB
Line Attenuation 28.5 dB 19.5 dB
CRC Errors 260 0

Hi marty2

Which firmware version is router running?

I actually can't remember now. I'll try that and see if it helps

just started getting this: Incorrect IPCP configuration

upgraded to latest firmware, i have billion 7404

driving me nuts as internet goes down every 5 min

what did people do to solve the problem?

i restarted the modem to Factory Settings and internet is up for 11 hours now. So looks like problem solved. so relieved. Thanks

I've just done a factory reset on mine, still goes down every 5-10 minutes!!!! This is driving me insane. Any other ideas?

Okay folks, this issue is rearing its ugly head with my 7402G & 8000/384 Internode connection, and has been since upgrading from 5.02f firmware to 5.53 and subsequently to 5.54. I should add that before & after each firmware upgrade, I reset the router to factory default and manually entered settings.

Occasionally I see the "Incorrect IPCP configuration", but more often than not it's simply a case of randomly dropping the PPPoE / PPPoA (I've tried both) connection and then remaining on "Attempting to connect" permanently until such time as I reboot it. Upon rebooting, it will log in as normal. The uptime before the drop in connection can be anything from 2 hours to 90 hours. Yep, it's so random, I can't replicate it.

In the event log, all that denotes the event is:
"Apr 23 14:59:58 home.gateway:ppp:none: Channel Id(0) disconnected after (28 hr 20 min 23 sec)
Apr 23 14:59:58 home.gateway:im_backend:none: Changed ipwan IP address to 0.0.0.0"

Thankfully, it has now happened during helpdesk hours, and Internode's HD confirmed the router was not logging in.

For me this has only been an issue since going from 5.02f which was perfectly stable (save for the dodgy wireless) to 5.53.

Oh, and for the sake of completeness, I upgraded to 5.53 a month before moving house, so the issue has spanned two different locations, but the same exchange, so I'm pretty certain the issue has nothing to do with my copper connection.

Quentin. writes...

Yep, I tried that. The router would not log in at all. Again, the status for the 30 minutes I left it going was "Attempting to connect".

I'm quite happy to email a backup for Billion's testing (albeit with a degree of hesitation if you need username/password), but for the life of me, I can't work out where the backup is saved to. It doesn't ask me to specify a 'save location'.

Bronze writes...

On at least one occasion i narrowed it down to a noisy electrical device being switched on (a cheapass power supply on an external HDD) - each time it would go on the modem would go 'click' and just loop the connect/disconnect cycle with the IPCP error. I could repeat this whenever i liked just by switching it on. Interestingly it doesnt do it anymore tho - which may be the splitter, who knows cant remember when it stopped.

OMFG! You solved it for me! I have a dodgy External HDD enclosure I bought for $30 from PC Case Gear, and it always never could keep a stable USB connection. I didn't use it for a while, but plugged it in a few days ago and it correlates with when my ADSL line started dropping out very very frequently. I have been on the phone multiple times to iiNet, upgraded the firmware and set to PPPoA/PAP and none of that worked. Then I read your post and switched off the external hard drive and my connection is now stable as a rock again!

THANKS!

Hi

When you click on backup it should come up with a window, you can then select where you want to save the file.

Please email me full details & i'll look at it.

An update to my problems...unfortuenately the the store I got it from seems to have ceased trading so i had to pay for postage to and from the distributor. They replaced the main pcb, and since then the modem has been rock solid, hasn't dropped out at all. So it was a faulty modem.

Hi,

Has anyone found a solution to this problem?

I upgraded my line speed with Internode from 1.5Mb/s to 8 Mb/s last Monday and since then have had the 'Incorrect IPCP Configuration' fault on my Billion 7402 VGP.

I've done all the usual isolation tests just in case, but my set-up hasn't changed for years now and I've never had the fault previously to the line speed change.

Sometimes the fault occurs when no computers are running, but another strange fault I have found is that I can get the fault to occur at the drop of a hat when I access the internet wirelessly with my laptop. Otherwise the fault just occurs sporadically.

Any help would be greatly appreciated.

Hi Mark

Have you upgraded to latest firmware (5.60c)?

Change to PPPoA/PAP.

Cheers

No.

Internode only recommends 5.52g. Is that OK or does it need to be 5.60c?

Did the firmware upgrade solve this for everyone else?

Thanks

amaru writes...

Hi

Please upgrade to 5.60c, this works fine with Internode.

Cheers

Bloody incorrect IPCP.... I have done 4 days of testing and THINK i have figured out what causes it.

1. Assuming there is some kind of switch in the router (ticking noise) on connection.

2. I can 100% of the time replicate the error WHEN:

Disconnecting PPP session from main router page AND

Reconnecting it before the "switch" ticks off.

100% of the time i get IPCP error

Hi

This is correct behaviour, relay switches to PSTN when ADSL connection has been lost & shouldn't have anything to do with this issue, as above ensure that router has latest firmware (5.60c).

Friend of mine did exactly the same a fortnight ago & has had no end of problems. His 7400 never missed a beat but now gets 'Incorrect IPCP Configuration' errors all the time. Often seems to be when he's talking on the phone. Hears a bit of static then finds the connection has been dropped. Download speeds seem to fluctuate wildly. At one point he was synching at under 200Kbs. Reboot modem & it'd be over 3000. Later in the day it dropped to 1700
Where is 5.60c? He updated to 5.54b but the problem persisted so rolled back to 5.53

Hey all.

I have now been experiencing ALL the problems everyone has listed in their posts;
so to cut a VERY LONG story short and to attempt to give all needed information
(and to try to avoid the dreaded 'wall of text'):

- Drop out problems started occuring approx. 1 month ago (prior to that the connection was pretty much rock-solid),
and have increased in severity while still remaining absolutely random.

- Firmware is the latest on hand, was factory reset after update.

- Drop outs occur with BOTH PPPoE/PPPoA encapsulation & Chap/Pap authentication

- I have done everything humanly possible on my end (eg. line isolation, different power sockets/different modems (admidttedly it was a D-Link DSL200 :-( )/encapsulation/authentications/line attenuation), to ultimately no avail.

- Average SNR: around 15.0db
Average CRC errors after 5 minutes of stable connection: 2000

- Called Internode (many many many times.). Called Billion, the bloke on the line pointed out the fact that it CAN'T be the router, as it was working perfectly and only started stuffing up, so it must be internodes fault. Called Internode back. They *finally* sent Telstra out to the exchange. They called back to tell me a 'battery' or somesuch had been removed from my phone line. Problems continued. Called Internode, got no where again. Called Telstra home phone fault line, who sent out another bloke to the pit somewhere near my home. Said he found some corroded cabling, and replaced it.
Problem *STILL* continues.

My final conlusion, after defending Billion routers to the death talking to Internode & Telstra, is that the problem ultimately lies within the router. Please note that I say this with great reluctance.

Phew. There we go. As you can tell the cut outs are pretty severe, and have happened multiple times as I was typing this.

Any help (from anyone!) to fix this problem would be greatly appreciated.

Did changing modems change the drop-out rate or did it persist?
If it resolved --> likely to be a Billion modem fault
If persisted --> likely to be a persistent line fault

Just quickly,
I solved the problem today..... by purchasing a Linksys Modem/Router.
