I have installed Ubuntu 14.04 on my system. Initially Wi-fi successfully connected to a networ. E.g.: "Mario"
After a while, I deleted "Mario" from edit connections. Then I tried to connect to the same Wi-fi again but it's not working. Why? How can I solve the problem?
lspci -knn | grep Net -A2
terminal command. – Pilot6 Jan 27 '17 at 12:47
