detects wifi networks but It does not connect

Post by gabrielp »

I tried to make the connections to the Wi-Fi networks but the truth is that it keeps loading as if it were going to connect but then it asks me for the password again. It should be noted that in linux manjaro something similar happened to me but it was a problem of power configuration. Also, I'm new to Linux so I appreciate your help.

I think the problem is with power management because it is on. I don't have any idea but how can I access to this configuration?

Re: detects wifi networks but It does not connect

Post by trytip »

there a few things to can try. first open /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf as root and change it to

Code: Select all

[connection]
wifi.powersave = 2
restart your network systemctl restart network-manager or reboot. this turns off power management may help or not can't say
