I have RTL8191SEvA wireless card, and as far as I cannot connect to wireless. Any help is appreciated. My attempts at diagnostics are documented below.

The computer is Shuttle XS35GTV2. I ensured that in the BIOS setting the "Wireless Power Control" is set to "Disabled" (so that BIOS does not turn off wireless card off). I even tried to reinstall the drivers from RealTek website, to no avail (nothing changes).

Any troubleshooting ideas are much appreciated!
