At last. The bug has been fixed in 3.6. I didn't test it directly but I tried compat-wireless (backported drivers) and It works perfect with linux 3.5. So if quantal is going to use 3.6 kernel, the bug will be fixed upstream.
If you want to fix your network experience before you can use 3.6 kernel, I recommend carl9170 from compat-wireless.
