Good for you.

I have a [10ec:8176] in my laptop and while I don't have the issues
Norbert is reporting, I can't say the thing just worked.

I had to use the wireless recently in a bunch of networks and what it
would do, is associate properly, connection gets established and traffic
is fine for a minute or so. Then, after a minute traffic would cease and
I'd need to re-associate. And it worked sporadically, sometimes fine,
sometimes with constant connection interruptions. And this observation
was the case with almost all wireless networks I'd use.

FWIW, the wifi adapter is:

using rtl8192ce.

Hmm.
