Title:
Bluetooth and Wifi: coexistence Problem
Status in linux package in Ubuntu:
Confirmed
Bug description:
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 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 previously been identified
with earlier versions of the Intel hardware (see
https://wiki.debian.org/iwlwifi#Troubleshooting) but not with the
8260.
