I'm new to the forum. However I'm not totally stranger to Ubuntu.
My Wifi behavior, is very non deterministic which means annoying.
I use laptop. Old e4300 with some broadcom card, What happens is:
i.e. I can be connected for two days without any issue, but soon I will notice a question sign on Wifi icon on taskbar. When it happens I cant even use IP address to reach my router. I can try to reconnect but it gives usually nothing.
Already tried :
/etc/resolv.conf refresh/with google dns
sudo systemd-resolve --flush-caches
fixed configuration and leased IP Address, with native router dns's and with those from Google. Issue always comeback and is really difficult to get rid of. Depends on luck, after few network device resets or re-connection attempts.
Nothing seems to work. Does anyone had similar issue but managed to resolve it? Please I appreciate your support.
Best regards Piotr
