|I think at this point in time you should check online for newer drivers for the device. If there are newer, apply them. If that doesn't fix the issue, I'd recommend trying a different USB Wireless interface if you either have another one you know works, or can borrow one.|
Trying another known "good" USB interface will at least let you know if it's the NIC itself, or the computer that's the problem.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
