Bug Description
The wifi device disconnect sometime randomly or sometime when switching hotspot with the following dmesg output:
[ 1039.212949] iwlwifi 0000:01:00.0: L1 Enabled - LTR Enabled
[ 1039.213503] iwlwifi 0000:01:00.0: L1 Enabled - LTR Enabled

The device at pcieport 0000:00:1c.0 seems to be the Intel 7265 wireless:
$ lspci -tv

To allow the device to connect again I use the following:
$ sudo systemctl restart network-
That said, the pcieport 0000:00:1c.0 dmesg outputs sometimes appears without affecting the wifi connection...
