Every time after I install linux distros, my net fall sometimes. I need to restart NetworkManager for restating wifi. Every installation I change some file for resolve this wifi problem( I just remeber that disable mac adress check, don’t know what does it mean),but I forgot that conretically. Secureboot disabled and Windows not installed. Mydevice is Dell Vostro.Can you tell me how resolve problem now?
It could be a problem with power saving. A quick search for disabling power saving on your wifi device in Linux should give you a solution.
I use TLP. It can help?
Maybe you can turn off power saving fro your wifi using tlp. I’ve never used it but a quick search led to this. I suppose you’d want off for both of them.
