Win Xp Strange Wireless Problem
in [Network and Web]

From: big country on 8 Jan 2010 20:18 Problem: Have an 11 meg internet connection,(download) But I cant get over 5 meg download (speakeasy test))when using my wireless connection. (using Linksys 11b/g/n router.) PC wireless adapter is at top bitrate of 54mbps. Info: Running windows XP sp3 all OS updates on a Dell Latitude d520. The wireless card is an 11b/g Dell Wireless 1390 WLAN Mini-Card with the latest drivers. When I go hard wired straight to my router I can get the full download throughput of 11 meg. I also have tried a Ubiquiti 11b/g wireless PC Card that connects at the top bitrate but can only get 5 meg download as well. Here's the kicker: My daughter has a Dell Studio Laptop. She can connect wirelessly at a bitrate of 54mbps to my router and she gets the full 11 meg download on speakeasy test. So that really blows my mind. Its like my laptop is forcing B only mode speeds regardless of what kind of wireless card I use even though its connects at G speeds. What I have done: Tinkered around with some of the advanced properties of the wireless driver. I have ran all the diagnostics that are included with the driver utility and everything passed. Thats about it. This is really got me stumped. I have ruled out a router problem and it cant be a tcp/ip problem with my PC since I can get the full speed over a hard wire. Anybody else run into this before?

From: big country on 9 Jan 2010 14:24 Hi Jack, man that Dr TCP worked beautifully! Thanks. Since I could get all of the 11 meg over a hard wire, I was thinking it was something at a higher level and not the tcp/ip stack. I did not realize the tcp/ip stack parameters could be different for each adapter.
