Hi, I have just upgraded my AAPT connection to ADSL2+ (upgraded from 512k) . My router/modem is the Netcomm NB9W running the latest firmware (NB9W-C211-S306NCM-C04_R02). I am running XP SP3 and use IE7 and have McAfee security centre installed/running. I usually use the wireless connection. I do not think I am getting the download speeds I should expect given I haven't noticed a significant change in speeds from my previous 512k connection. I spoke to AAPT and they say the line speeds are fine. I spoke to Netcomm and they suggested setting the DSL option on the modem to ADSL2+ only which I've done. No change to speed – I've used several of the standard speed tests and am averaging about 320 KBytes/s for downloads. This is similar for wireless/cabled. The NB9W is plugged directly to phone socket and cable is only approx 2m. The exchange is literally across the road from me. I've looked at the NB9Ws stats and the Rate (Kbps) says 18140 for downloads that appears to agree with the numbers AAPT gave me. So why are download rates so poor? I'm far from expert and don't know what else to change to improve download rates. Not sure what other info to provide – here's the stats from my NB9W. Any advice appreciated. Thanks, Jonny Mode: ADSL2+ |

What you need to do is run a test such as downloading from www2.aapt.com.au/speedtest.bin – maybe run multiple downloads and check the performance. |

Thanks Scottatron. This is one of the tests I've already run. With the AAPT test I got a speed of 400KBytes/s (the best result of all the speed tests). I've also done isolation tests as suggested in other posts on similar issues and the results haven't been any different. I'm also familiar with the multi-part download apps. For the AAPT download test what would be a 'good' result (speed) for a single threaded download (given the setup parameters/environment described in my original post)? What do other folks get? (maybe I'm under false illusions as to what to expect) I've also run DrTCP and that suggested changing my MTU to 1500 and RWIN to >=187680 & <= 500480. I did the MTU change but not the RWIN change as yet. The MTU change doesn't appear to have made any difference – I changed it on my laptop but couldn't find this setting on the NB9W settings (does the PC/router MTU settings need to be aligned?) |

I have the same issue as you, I only get about 300kps though wifi on most speed tests (the www2.aapt.com.au/speedtest.bin and also http://www.ozspeedtest.com/bandwidth). But when I use my other computer connected using ethernet I get correct speed of almost 800kbps (The almost what my modem says it is sycn'd at). I am just puttting it down to being a issue with WIFI in general. P.S. I am a happy EscapeNet user, not AAPT. |

400 does seem a little slow, considering you have synced up at around 18meg. |

Is there any way you can bypass the wireless and use an ethernet connection to the router? |

I could bypass the wireless but that kind of defeats the purpose of the wireless – otherwise I'm gonna have ethernet cable strung across the living room. I could do the 'mains' ethernet adapter thing but that's a pricey option. Besides, when I went cabled ethernet to see how it stacked up against wireless the results weren't very different. When I did the DrTCP thing, the tweak test said to change my MTU to 1500. I did this (on the Intel PROset/wirless adapter) and it said the changes were saved and I ran the tweak test again and it still said change the MTU to 1500? I presume I wouldn't need to change the MTU setting for the cabled internet adapter given I'm not using it? I may just have to accept my download speeds aren't going to improve. I agree the AAPT connection is fine. |

I may just have to accept my download speeds aren't going to improve. I agree the AAPT connection is fine. I wouldn't give up hope just yet. Try another modem from a friend, make sure its ADSL2+ capable and test the downloads again. Have you tried running multiple AAPT speedtests at the same time? Give it a go, you may find you can have 2 or 3 speedtests running at 400KB/s which would mean your getting good speeds and the limitations are coming from the sources you are connected to. |

Just ran the AAPT download test in parallel x6 (over wireless) and averaged 250KBytes/s so total rate was approx 1.5MB/s that seems very reasonable. I should be satisfied with that. Thanks to you guys Scottatron, Mr E, 5tumpy & Lat! |

Still a little low for an 18mbps connection, but not low enough to worry... Looks like a limitation on the AAPT speedtest... Very interesting! |

Just ran the AAPT download test in parallel x6 (over wireless) and averaged 250KBytes/s I had this problem when I switched from 1.5mb to 8mb, I downloaded TCPOptimizer, selected 'Optimized settings' from memory and tweaked some others and I could then max out the download speed on one single download. Could be worth a try. |

Agreed, but if he's syncing up that quickly, then the problem isn't in AAPT's network... While the OP's problem isnt in the AAPT network what you sync up at has nothing to do with their network either. |

But 90% of the time, if you're syncing at that high a speed, there's no problem with the line... many, many problems, like how no one will peer with them makes things difficult.... Exactly my point... |

Ok so youre saying that phone lines and DSLAMs are part of an ISPs network, I wouldn't personally particularly when talking about speed issues specifically, but thats obviously where some peoples confusion is coming from with regards to that statement. |
