For a home network I want to set up my Billion 7300 DSL/router in combo with a Linksys WRT350N (standard firmware), as I have more wired devices than either has ports.

The house is brand new and wired with Cat6 in two studies, rumpus and media areas. I want to use the 350N as it is a Gbit/802.11n device and the LAN will contain a mixture of 100Mbit and GBit devices. The network I want to set up is users.tpg.com.au/706/bil...s350ninterop.jpg, with GBit devices connected to the 350N and the less used 100MBit devices connecting to the 7300.

The 7300 is currently being used as the modem/router and I need to keep using it as the DSL modem, as the estate is pair-gained and the other two DSL modems I have (and old OptusNet D-Link 302G and a brand new Linksys AM300) refuse to work.

What I need to know is, can this be set up as indicated in the pic, and if so, which device should be the DHCP server, how should the subnets be configured, etc.

All help appreciated.

How many PCs do you have that you need two routers??? really unless you have 100+ pcs you probably don't need multiple routers. Use a switch and bridge instead of the linksys or set the 7300 to be a modem only.

Funds are limited so I'd prefer not to plug in a new switch and want to avoid any cable swapping of ports, and also use the 350N's wireless. For the number of puters, see the network diagram linked above.

Set tbe billion to be a modem only. Set wiresless network to 192.168.2.0/24 and set the wired network to 192.168.1.0. The DHCP server can be either as long as the default gateway always points to the link sys device. You will probably want to setup a WINS and/or a DNS server as well.

/24?

You need to enable one of the modems to be a "Dhcp relay server" or something along those lines. Right now what is going on is both of them are attempting to assign IP addresses. And ofcourse getting rather confused

You need to tell one to forward dhcp requests to the other.

Set the IP of the first router to x.x.x.1 and the second router to x.x.x.2 Otherwise they will probably both attempt to use the same IP's which will also cause more problems. Connect your PC straight into each router one at a time till you get the IP's and DHCP settings right.

that indicate the size of your subnet.
/24 is equivalent to 255.255.255.0 netmask

OK I'll give that a shot. TY all.

I'd have tought the simplest way would be to plug the Billion into one of the LAN ports of the WRT350 and disable DHCP on the WRT350. Pete's guide here will help. /forum-replies.cfm?t=933757

Cheers,

I am trying a very similar thing at present. Existing Billion modem/router/wireless device. I have a new D Link wirless router only - no modem. I'm hoping it's range is better than billion. I want to continue to use the billion as the modem + switch with the D Link acting as the main router - wired & wireless.

Am I correct that i should disable WLAN on the billion and turn off DHCP also. Up link from Billion port 1 to the D Link router. Configure D lInk router as the DHCP server and Wireless Access point?

I actually do need an extra port for so need to use one port of the billion for wired network access.

You need to do more than just disable DHCP on one. Otherwise you'll be stuck with two subnets and clients not having access to other subnet.

If you need all computers, irrespective of which router they connect to (wireless or LAN), to be able to see each other (ie same subnet) then disabling the routing function of one will keep all happy. I have a NAS box and a media center that need to be accessible on the one subnet.

I can also access either router's web admin, irrespective of which router I connect to (not easy if on diff subnet).

Having two routers connected would otherwise create two subnets.

ie. i am using this:-

a) Billion 192.168.0.1 (ADSL, wireless and lan ports)

b) linksys WRT54GL(DDWRT firmware), 192.168.0.2

(DHCP server forwards to Billion or vice versa) ie. only 1 DHCP active.

the DDWRT firmware on the WRT54 allows:-
i) WAN CONNECTION TYPE: disabled (instead of a feed from the ADSL)
ii) assign WAN port to switch (so "WAN" port is now another LAN port) if you need it)
iii) feed a LAN from the Billion ADSL router to any port of the WRT54.
iv) gateway pointing at the Billion and also STATIC DNS's that the ISP allocates (check the Primary and 2ndary DNS allocated on the Billion and duplicate on the WRT)
.

All on one subnet, all happy, all can wake up the NAS box, irrespective of which router connected to.

so my two cents worth.

Check if linksys has a DHCP relay setting in the DHCP part of the LAN.
then it will be sweet!!!
