Public bug reported:

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.

Title:
  rtl8188ee constantly dropping connections

Status in “linux” package in Ubuntu:
  Incomplete

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.
