Comment 0 for bug 1721271

I'm currently running kernel 4.13.0-12 on Ubuntu 17.10 (daily) and have noticed that with my Intel Corporation Wireless 8260 (rev 3a) there appears to be a problem with buetooth and wifi coexistence.

Unless I disable bluetooth and/or wifi I am unable to connect to either the opposite to which I have disabled.

Adding:

options iwlwifi bt_coex_active=0 swcrypto=1 11n_disable=8

To:

/etc/modprobe.d/iwlwifi.conf

Solve the problem. This is a reversion to less functionality as on earlier kernels (default kernel on 17.04) this did not occur.

This would appear to be a problem that has previousl been identified with earlier versions of the Intel hardware (see https://wiki.debian.org/iwlwifi#Troubleshooting) but not with the 8260.
