Only really happens when I'm playing a game that requires online functionality to work. For example, Final Fantasy XIV through XIVLauncher, or Halo MCC through Steam. I suspect Wine might be a cause as well, but I don't know exactly. The WiFi card in question is an Intel AX200. I changed DHCP clients to dhclient and it still happens, so something within Network Manager is telling it to renew the lease, despite it not needing to be renewed. This can happen from every 5 minutes to every 5 seconds. Reproducible: Always Steps to Reproduce: 1. play game online Actual Results: Being disconnected due to Network Manager renewing DHCP lease despite it not needing to be renewed. Expected Results: Not being disconnected.
Please set level=TRACE in the logging section of /etc/NetworkManager/NetworkManager.conf, restart the NetworkManager service, reproduce the issue and then attach the output of "journalctl -u NetworkManager -b".
Created attachment 1981380 [details] networkmanager journalctl log Here you go, happened right near the end.
The first strange thing I see is that there is a process with pid 6998 that is requesting secrets every 10 seconds: Aug 02 19:27:50 g14-linux NetworkManager[269368]: <trace> [1691018870.8935] auth: call[221]: CheckAuthorization(org.freedesktop.NetworkManager.settings.modify.system), subject=unix-process[pid=6998, uid=1000, start=16313] Aug 02 19:28:00 g14-linux NetworkManager[269368]: <trace> [1691018880.9220] auth: call[222]: CheckAuthorization(org.freedesktop.NetworkManager.settings.modify.system), subject=unix-process[pid=6998, uid=1000, start=16313] Aug 02 19:28:10 g14-linux NetworkManager[269368]: <trace> [1691018890.9488] auth: call[223]: CheckAuthorization(org.freedesktop.NetworkManager.settings.modify.system), subject=unix-process[pid=6998, uid=1000, start=16313] ... The actual problem is here, where the wireless interface loses carrier: Aug 02 19:34:20 g14-linux NetworkManager[269368]: <debug> [1691019260.5741] platform: (wlp2s0) signal: link changed: 2: wlp2s0 <UP;broadcast,multicast,up> mtu 1500 arp 1 wifi? init addrgenmode none addr A8:7E:EA:75:45:9A permaddr A8:7E:EA:75:45:9A brd FF:FF:FF:FF:FF:FF driver iwlwifi rx:5929333,3863781104 tx:3894728,1088928061 and then wpa_supplicant reports a disconnection: Aug 02 19:34:20 g14-linux NetworkManager[269368]: <info> [1691019260.6876] device (wlp2s0): supplicant interface state: completed -> disconnected To understand the reason, you need to enable logging in wpa_supplicant and analyze logs.
How would I go about doing that?
Add -ddd to OTHER_ARGS in /etc/sysconfig/wpa_supplicant and restart the service or reboot. Reproduce the issue and then check logs with "journalctl -u wpa_supplicant -b"
Unfortunately after doing this I cannot reproduce it. I've been trying ever since and it won't reproduce. If it happens again I'll post logs.
