  conceptronic (WIFI card/adapter/dongle)
  Mint (older version)
  Works partially
What works:

Detecting networks & connecting works fine.

What doesn't work:

The connection is very slow and it often disconnects.

What was done to make it work:

To fix the disconnects (it doesn't fix the slow connection):
Download compat-wireless from http://www.orbit-lab.org/kernel/compat-wireless-2.6/compat-wireless-2.6.tar.bz2
Unpack the archive, and go to the folder where you unpacked it. Right-click > Open in terminal.
Run these commands:
$ ./scripts/driver-select ath5k
$ make
$ sudo make install

Additional notes:

Atheros 5002G (5212+2112) chipset
