Comment 7 for bug 1571535

Having run with just the 2.4MHz network for a while, something still isn't right. Every so often the network just stops talking. NetworkManger still thinks its connected, but no traffic seems to pass. It logs nothing when this happens (I'm guessing it gets detected, though, as that would explain the 2.4 <-> 5 switching I was seeing before)

I would suspect the router at this point, but another machine (with a different Intel chipset - lspci says Centrino Wireless-N 1030) never has any issues and, as mentioned originally, this only started after installing xenial, wily was fine.

I'm out of ideas how how to try and debug this further. For reference I'm now using the 4.4.0-21-generic kernel.
