Title:
Intel AX201 / Thinkpad X1 Carbon Gen 9 returns ping during WiFi roam
Status in linux package in Ubuntu:
Confirmed
Status in network-manager package in Ubuntu:
New
Bug description:
My Thinkpad X1 Carbon Gen 9 has started to return pings in the middle
of WiFi roam events which is causing the IP address to change every
time it roams on the WiFi network. This is a huge problem for me
because I install WiFi networks for a living but in general it causes
every TCP connection over IPv4 to die every time the laptop roams to a
new wifi cell.
00:14.3 Network controller: Intel Corporation Wi-Fi 6 AX201 (rev 20)
I tried kernel 5.15.0-40-generic and mainline kernel 5.17 and 5.18.
