[Bug 987014] Re: realtec WiFi driver instable on Thinkpad x120e
Andreas Siegert, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please just make a comment to this.
Also, could you please test the latest upstream kernel available v3.12 (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.12
This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

** Description changed:
The realtec WiFi driver shipped with 2.4 beta2 is not very stable, leading to dropped connections or connection re-establisment quite often.
Just like on 11.10.
