Phone [Q] 4.4.2 SlimKat can't see my WiFi USB Stick

Title says almost everything. I had SlimBean b4 and my phone saw my Tp-Link wifi stick, but yesterday i updated it to slimkat, and since then it can't see my ad-hoc WEP security stick. But it can see all other router shared wi-fis. It's definately not my stick and not my phone bacause it was working previously.
Anyone having and idea what's causing the problem and how can i fix it. I'd really like to run that SlimKat on my phone, but this issue drives me crazy.

Thanks, and sorry for my typos, english is not my native.
