Cannot get wireless to work

Hi,

I've got 2 wireless cards (TL-WDN4800 and chinese Mediatek 7612 based one) and I can't get either of them to work. Here are a couple of pastes:

When trying the mediatek card I'm getting an error. The tp-link card though I can't see from my laptop though there are no errors.
I'm using the latest snapshot but the result is the same with all stable versions.
Do you need any additional info - I've been using wifi config with just enabling the interface and everything else is unchanged.

Regards
