[Kernel-packages] [Bug 1981366] Re: Intel AX201 / Thinkpad X1 Carbon Gen 9 returns ping during WiFi roam
The reason blocking pings prevents the IP address change is because a lot of DHCP servers ping the IP before they (re)allocate the address. If the device responds to the ping then the DHCP server abandons the IP and leases a new one. For this reason the network stack should; in my opinion ignore IPv4 ICMP echo requests during the DHCP part of the roam process. Indeed I believe that this was the behaviour previously. Blocking IPv4 pings isnt impacting any other functionality for me. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1981366 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: Confirmed 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.

The only upstream bug that seems potentially related is https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/1024 . But that's more about ensuring that WPA auth has completed before starting the DHCP renewal, and it's not clear to me how blocking ICMP could avoid that problem. So it might not actually be related. The fix for that issue went into development version NM 1.39.9, so I may try building and trying an upstream version which includes it, to see if that fixes the problem (but I won't be able to try before next week at the earliest). ** Bug watch added: gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues #1024 https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/1024 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1981366 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: Confirmed 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.

[Kernel-packages] [Bug 1981366] Re: Intel AX201 / Thinkpad X1 Carbon Gen 9 returns ping during WiFi roam
I have the same symptoms on Ubuntu 22.04.1 on a 12th-gen Framework laptop with Intel Wi-Fi 6 AX210/AX211/AX411 160MHz (rev 1a) device. Every time wpa-supplicant chooses to associate with a different BSSID (of the same SSID), the interface ends up being given a new IP address by the DHCP server (usually the sequentially next address). I don't have access to the DHCP server or its logs, but I tried the above suggested workaround of setting net.ipv4.icmp_echo_ignore_all=1 and this prevents the problem from occurring. So I expect the root cause is the same. (And as an aside, there is nothing in the client- side logs to indicate that ICMP pings could be in any way related; without this report it would have much more difficult to diagnose and work around the problem.) A different laptop running 18.04 on the same network is able to keep its IP address when roaming, so presumably this is due to a change in NetworkManager behaviour. The problem makes it difficult to work in an enterprise office environment (ie. moving around between desks and meeting rooms), because all TCP connections are lost when the IP address changes, which is especially impactful for ssh connections. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1981366 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: Confirmed 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.

I edited /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf changing wifi.powersave = 3 to wifi.powersave = 2. This improved the stability of the WiFi and appears to have stopped the continuous 'roaming'. I will keep an eye on the dhcp logs at home and report back if the 'ping during roam' continues. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1981366 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.
