Restart computer.
Hold Shift key to enter Grub menu.
Select Advanced Options
Select Linux Mint, with Linux 4.10.0-35-generic
Remove kernel 4.11.0-13 from Update Manager > View > Linux Kernels

Assuming everything worked fine on kernel 4.10.0-35.

Hello, mate. Firstly, if you haven't got any problems after the kernel upgrade other than wifi not working ; you ought to tinker and tweak here'n'there, that is assuming you have a few minutes off your schedule.

Just today itself, I upgraded from 4.12 to 4.13 and I was in same boat as yours. There was no option for wifi in network manager. Heck, even iwconfig returned no wireless extensions found. Now, what I did is this : I simply reinstalled the package named 'iw' in package manager and now, after reboot my wifi is up and running.

Cheers, have a nice day :D

Hi - I have a similar problem - performed a new install of Mint 18.2 - this has Kernel 4.10.0-35 - which does not support wireless.
However if I boot up from a previous install with my USB I get a full working version which uses Kernel 4.8.0 -53, but upon restart it reverts back to the 4.10 set up.
I have gone to View Linux Kernels - installed 4.8.0-53 - but I cannot uninstall this 4.10 set up. it says IN Use.
So how can I remove the troubled Kernel and replace with a working version.

you must boot from kernel 4.8 and then remove kernel 4.10

Indeed so. Forum member dark has already described in this thread how to boot from a previous kernel:

Got it thanks - it worked - I have spent the last two weeks trying to sort this wireless business - why do they issue a kernel update hat doesn't support wireless.

Doesn't support *your* wireless. :wink:

Reason: Murphy's law.
