Ubuntu: 16.04 wifi recently started dropping connection, how to find the cause?



Question:

My wifi has until recently worked flawlessly. Returning after 4 days away recent updates have meant that it drops frequently. I am using16.04LTS, my wifi card is a RTL8812AE and some 31 packages were installed by the Software updater. Seeing several threads noting that kernel 4.4.0-77 had at one point been the cause of wifi drops, I removed it and reverted to 4.4.0-75. This did not solve the problem, so I put -77 back with synaptic. Starting from the GRUB advance menu option of 4.4.0-75, seems to make it a bit better but I'm not convinced it holds up all the time.

How can I determine the cause of the drop? What log can I look at? Any possible fixes to using 4.4.0-77 all the time would be much appreciated.

The machine is a dual boot ASUS X555LAB

Update

Before the wifi icon disappears, I lose connection such that I cannot ping the gateway 192.168.0.1 (host unreachable). Starting from Grub option 4.4.0-75 and disabling/ignoring IPv6 does not make it work either
