Win Xp Strange Wireless Problem

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?
 
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.

Hi
For Vista and Win 7 this can be used.
It is much more complicated than Dr.TCP.
Give it a try may be you'll be capable to figure it out.

Thanks for the link.
Afraid I ran "Dr.TCP" on my Vista notebook yesterday, by accident... using
the suggested settings.
Although I notice no ill effects, would it be best to restore te default
settings before proceeding with this?

Any source as how to check the default settings for Vista?
Or would it be sufficient to run "SG Vista TCP/IP Patch" from your link in
this message above?
