I have noticed (and that just means I have noticed in the logs, not sure when it started) an endless chain of every 3 seconds
Sep 12 00:41:15 cachyos-x8664 wpa_supplicant[841]: wlan0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-54 noise=9999 txrate=15000
Doing my own investigation, I found that it doesn’t appear to be an issue in the LTS kernel, but I usually track the current.
Doesn’t really seem to impact traffic, just a log annoyance, though there may be some impact (I haven’t profiled it strictly). The signal is actually in the good range, about 30 feet from the router with one interior wall between it and the pc in question.
An obvious fix is to run LTS, but that will of course likely bite me when LTS advances past current.
My device affected is reporting as ‘MEDIATEK MT7922 802.11ax wifi (mt7921e)’ and is a motherboard component on my Asus MB.
I know this isn’t a cachy problem but a kernel issue, would the proper thing be to run down the maintainer of the driver and work with him/her? Pointers are welcome!
