Do you have some duplicated AP connection and nm will not stop? Your log shows successive de/re-authentication with different APs, e.g. first with 70:58:a4:d2:14:21 and then within seconds: disconnect from AP 70:58:a4:d2:14:21 for new auth to 70:58:a4:d2:14:29 > - similarly with `s/restart/stop`, and `pkill -9 NetworkManager` has no > effect!

Take a look at this page and consider all suggestions. In particular, *wpa_supplicant is no longer recommended* and iwd should be used instead: https://wiki.gentoo.org/wiki/NetworkManager https://wiki.gentoo.org/wiki/Iwd > I checked my hardware with `lspci`, which I'd fortunately installed during > the main system installation process, and with `lspci -k` I found out my > network card is > > ``` > c0:00.0 Mediatek MT7925 (RZ717) Wi-Fi 7 160MHz [14c3:0717] > ``` > > with kernel module (in use) `mt7925e`. > > First, I tried turning off WiFi power saving [as recommended by Garuda > folks](https://forum.garudalinux.org/t/mediatek-mt7925e-wifi-speed-very-slow > -on-close-to-fresh-install-and-some-updates/41845/11): [snip ...] > Here's a [capture between a reboot and when I saw the problem > again](https://paste.gentoo.zip/gIeCuVQ4); I can also see `chronyd` fail > (probably because the network is down) and some things about DHCP lease > expiry or failures.

It is much safer to try pressing keys R E I S U B ("busier" backwards) while holding down Alt + SysRq (or Print Screen button if SysRq is not available): https://en.wikipedia.org/wiki/Magic_SysRq_key > Relevant information: > - [`/etc/conf.d/netmount`](https://bpa.st/5QMN6): I only found out about > this file from `view /etc/conf.d/net*` while reading [the Handbook's > troubleshooting You shouldn't mix 'n match uncaringly different methods for managing your wireless network connectivity. You can end up with one system fighting for control against the other. I you prefer networkmanager, then the above links I shared ought to help you configure it correctly. Otherwise please post back.
