I have a Linux machine, and I'll switch between using an RTL8187 based card, and a RT2800USB based card (the cards are both USB dongles by the same manufacturer).
I've loaded the drivers for both cards:
modprobe rtl8187 modprobe rt2800usb
I can run an iwlist scan against the RTL8187 card until I'm blue in the face, but after a few minutes of doing the same with the RT2800USB card, it stops working, and displays the following:
$ sudo iwlist wlan0 scan wlan0 No scan results
What can I do to get the card to work 100%?
