Wireless disconnects, but wired fine?

[Darkenmal]

I have changed the channels, changed the firmware, changed the position of the wireless router, reinserted my wireless card on my rig, changed the security, turned everything setting on or off....

I've done everything I can think of.

I have a TP - Link router:

Model No. TL-WR940N

Firmware Version:
3.13.9 Build 120201 Rel.54965n

Hardware Version:
WR940N v1/WR941N v4 00000000

It cuts out for my laptop and my other stuff as well, but not nearly as bad as my desktop rig. If the internet crashes on my desktop, it can take from 2 - 15 minutes for it to come back.

I'm out of ways to fix it... could it be my wireless card? Or something else?

Just help me out guys... im desperate... the wired works fine btw.

what wireless mode are you using? WEP, WPA, or WPA2

have you tried setting the Channel Width to 20MHz?

WPA 2 and yes.
