I have had this same problem for months now since. Very frustrating as it seems
so random. I have gone as long as a few days without losing connection and
other times I have to reboot several times a day. Never had this problem with
prior version of Lubuntu.

I do not have a solution for this but I have also been trying to locate
a fix for a couple of months now. I have 5 systems running Lubuntu and
only one is having this issue which is also using an Intel wireless
card. The other 4 systems are using either a Buffalo or TPLink card. I
have tried checking the regulatory domain, disabled ipv6, tried enabling
antenna aggregation, tried 2.4ghz instead of 5, disabled n mode,
disabled bluetooth, disabled bluetooth coexistence, disabled power
management, turned off watchdog, and I am sure I have tried a few other
things that I do not recall at the moment.
