OK, after leaving the system running for a few hours running 3.17, I'm
showing 5 spurious disconnects in the same number of hours with the same
information in the logs as above. And I don't know if it helps, but I
found someone else is having the same problem with a very similar
notebook, so it may be something particular to this model? I can't
understand the details or if there was a solution since it's in German.
But if it helps, it's http://forum.ubuntuusers.de/topic/rtl8188ee-wlan-

Title:
rtl8188ee constantly dropping connections
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Not sure how long this has been happening since I recently switched
out routers to a dd-wrt and it likes to restart the connection
whenever you make a change. It could have been happening before that
since I switched out the other router because it was acting weird (not
related I don't think, but wasn't dropping connection ... but it had 4
amplified aerials). New router has internal, but my phone is right
next to me and its connection is worse (SNR wise) but stable. Laptop
is NOT stable.
Seems to be similar to Bug #1349108, but that one was a different
driver. And I don't want to post the entire log since I've got the
dd-wrt, the cisco, cron jobs, and all kinds of stuff going to my
syslog, and I checked .. the mrtg run doesn't always preceed the
"lost" message, but it was fairly common that it does. The same
messages repeat forever (weekly log rotations show from 69 to over 250
occurances per log file). Let me know what other info I can give.
This was stable some weeks ago, but I can't tell you what I changed or
when.
