Comment 15 for bug 1622293

Wifi drops with Ubuntu version 16.04.2 LTS (hardware enablement turned on) with kernel versions 4.10.0-27 and 4.10.0-28. It worked OK with kernel 4.8.0-58. The kernel upgrade was done when prompted by Ubuntu.

The wifi drops when BBC's iplayer or any of the speed test sites downloads a lot of data.

The wifi configuration as produced by a sudo lshw -C network is:

*-network

After the wifi is dropped, the command sudo service network-manager restart does not turn on the wifi again
