Bug Description
when using the combo of Intel 6205N (IBM ThinkPad T430s) and TP-Link TL-WDR4300 router there is a problem of sudden loss of connectivity after a "bandwidth change" event is registered by wifi module.
In log:
Feb 10 13:09:28 lenovo kernel: [1981878.856612] wlan0: AP <redacted> changed bandwidth, new config is 2462 M
Hz, width 1 (2462/0 MHz)
Feb 10 13:09:31 lenovo kernel: [1981881.929193] wlan0: AP <redacted> changed bandwidth, new config is 2462 M
Hz, width 2 (2452/0 MHz)
After that point no frames are coming from the router. I.e. even ARP is not resolving, although the wifi connection seems to look fine in NetworkManager. Restarting networking or killing wpa_supplicant solves the problem for a while.
