Linux Mint 18.2 BETA -- Wifi issues with Intel 8265

[romanpete]

Thanks for the opportunity to review the beta version of Mint 18.2 “Sonya” Cinnamon.

I have been struggling with a hardware problem in my DELL XPS13 9365 which relates to the Intel 8265 (802.11ac 2x2 WiFi and Bluetooth) adapter. Both Fedora 25 and Ubuntu 16 recognize and work with this hardware but it seems that Mint 18 can only make use of either the WiFi or the Bluetooth, but not both. This depends on which kernel I am running.

4.4.0-53-generic Bluetooth works WiFi does not
4.8.0-54-generic No Bluetooth WiFi OK
4.10.0-22-generic No Bluetooth WiFi OK

When running the later kernels, the Bluetooth adapter is either not detectable or not manageable by the "Blueman-Applet” v2.04 ,or the native Mint 18.1 Bluetooth tool, which curiously sees my XPS13 as being “Bastien’s computer”.

UNFORTUNATELY, when I tried running a live version of the 18.2 beta, the new “Blueberry” bluetooth manager simply refused to run and I had no bluetooth connectivity. The WiFi seems to run perfectly well.

So I must add the following info to the table above:

4.8.0-53-generic No Bluetooth WiFi OK

Hopefully your team will be able to sort this out for the final release of of what looks to be a very neat version of Mint!
A fuller description of my system follows, and I would be happy to try out any suggestions you might have. I really DO want to run Mint ...

Cheers!

With the 4.8 kernel, in terminal try

Code: Select all

bluetoothctl

Code: Select all

power on

Code: Select all

scan on

use CTRL + d to exit

We can get your wifi to work in the 4.4 kernel using kernel backports from Intel
You must have been using Ubuntu 16.04.2 as Ubuntu 16.04 and Ubuntu 16.04.1 use the same 4.4 kernels as Linux Mint. I am not exactly sure why LM has issues with the bluetooth in the 4.8 and 4.10 kernels UNLESS it is firmware related and a simple

Code: Select all

sudo apt-get update && sudo apt-get install linux-firmware

along with a reboot may fix
