[Bug 1586650] Re: Ubuntu 16.04 touchy WiFi Internet
N, the next step is to fully reverse commit bisect from kernel 4.4 to
4.7-rc3 in order to identify the last bad commit, followed immediately
by the first good one. Once this good commit has been identified, it may
be reviewed for backporting. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?
Please note, finding adjacent kernel versions is not fully commit
bisecting.
Also, the kernel release names are irrelevant for the purposes of
bisecting.
After the fix commit (not kernel version) has been identified, then
please mark this report Status Confirmed.
Thank you for your understanding.

Title:
Ubuntu 16.04 touchy WiFi Internet
Status in linux package in Ubuntu:
Incomplete
Bug description:
When I installed Ubuntu 16.04 I had to reconfigure our modem and
router setup from bridge mode to DHCP mode. As a result, I lost all
ability on my computer to connect to WiFi.
However, the other eight connected devices (ex. iPad, PlayStation)
have Internet connection.
After power-cycling our router and modem I'm now able to connect but I
get 2 Mbps download speed, and web pages load up slowly.
