[Bug 1238968] Re: Wireless connection drops and cannot be re-established
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.12 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".
Thanks in advance.

Title:
Wireless connection drops and cannot be re-established
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
This is coming from bug #1000208.
Spontaneously, the wireless connection stops working. That is, the
applet still shows that it's connected, but no traffic is going
through. On attempting to disconnect and reconnect, connection is not
possible. It continuously fails. One can only reconnect using the
following workaround, or rebooting.
Workaround:
sudo /sbin/rmmod rtl8192se; sudo killall NetworkManager; sudo modprobe rtl8192se
