Bug#815037: problem still present in Stretch and stretch-backports?
Hi,
I am seeing this problem with
linux-image-4.15.0-0.bpo.2-amd64 4.15.11-1~bpo9+1 amd64 and firmware-iwlwifi 20170823-1~bpo9+1, and with their counterparts from Stable on my
XPS 13 from around 2013.
FWIW, on some networks, I have no trouble connecting, but on others, it just
won't work at all. I've tried this backport version after losing
connectivity with the stable package.
