Network connection "hangs". It happens if some bigger file is being downloaded.
Last mainline that works perfect for me is 3.1.10-precise. Next one 3.2-rc1-oneiric has the issue. This doesn't depend on firmware - it happens with all available firmware versions: 1.9.3, 1.9.4, 1.9.5. I use USB wireless card TP-LINK TL-WN821N. The device works perfect with Oneiric, breaks with Precise.
Kernel 3.3 (mainline) is affected. Kernel 3.4 rc1 performs much better, I can download much more data (few hundred MB) but than it also breaks (freezes) connection and doesn't reconnect.

Luciferion, thank you for reporting this and helping make Ubuntu better. If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
