Thanks!
i found the /e/ OS way to reboot into safe mode here
but i first tried the
settings > system > advanced > reset options > Reset Wi-Fi, mobile & Bluetooth.
But the wifi connection did disconnect again afterwards.
next, i’ll find out what’s involved with the reboot
–edit-- it’s now connected to the 5Ghz band and didn’t fail in the last 8 hours.
(in my case,at least at 2.4Ghz it shows that problem.
WIFI analyzer showed there’s multiple people in the same 2.4Ghz channel, but not on my 5Ghz channel)
