Hi,
I have installed Ubuntu 14.10 on my new laptop (64 bits) on Oct. 25 and
I got my laptop on Oct. 24, 2014, but after running "modprobe -r
r8192ee" command and "modprobe r8192ee", where "r8192ee" is the name of
my wireless module, my wireless connection cannot reconnect to the
internet, even though it finds the wireless networks and tries to
reconnect but it fails. I actually notice this bug after my laptop went
to sleep mode (by closing its lid) and then it was unable to reconnect
to wireless again. The only I can solve it now is by restarting.
I have tried it with AP at my home which the router is nearby and with
AP at my university which is public. In both cases it happends. I do not
have any other problem with these APs with the other laptop I have.
The wireless hardware in my laptop (Lenovo T440) was not working at all
in Ubuntu 14.04, I have teseted it in this week, and it was reported as
a confirmed bug. I could not run "upstream's compat-wireless backports".
Here are the details about it:
