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.
