I think this is the upstream bug: https://bugzilla.kernel.org/show_bug.cgi?id=197147, matches exactly my symptoms, Issue is present from kernel 4.13 upward.

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.
