False slow connection

[Chocobo_17]

Hi, first off, I recently moved my home wireless network/router to a different room in my house for various reasons. I didn't think it would affect my connectivity on my desktop, but for some unforeseen reason, it has. I know the router is working fine because the connection is exactly the same strength as it was before on the laptop. My desktop has suffered a severe drop in speed and I have no idea why. I haven't changed anything.

Laptop has built in wireless card. Desktop has an Encore USB wireless adapter seen here:

Any help or insight would be greatly appreciated.

EDIT: I updated the drivers and it helped a little, but problem still exists.

You can't rely on signal strength indicators.

You should try to optimise your reception and avoid interference.

1) raise the router above furniture level
2) Experiment with channels (some will work better or worse depending on your environment)
3) If you can detect strong neighbouring wifi, use a channel 5 stops away from strongest.
4) Relocate cordless phone base or video sender etc.
5) Be prepared to move the computer (or at least turn it so your body is not between the router signal and the wireless adapter's antenna.
