This is my network manager config file at /etc/NetworkManager/nfĮther 2c:4d:54:c0:e3:a1 txqueuelen 1000 (Ethernet) I have a Intel Corporation Wireless 8260 (rev 3a) network card. So its quite annoying when having to connect to a new one every 1,5 hours or so.
But at my college we have a wifi access points in every classroom and i try connecting to the closest one. These problems are not an issue when i am home because it connects to my home network right away and its OK. i have probably connected to that network a 100 times before. It connects automatically to a random network when i login but when i try to connect to a wifi network with a better signal i have type in the password. it seems like nmtui also keeps "forgetting" the passwords for some networks. it doesnt see all the networks in my area and when i try to connect to some it says in nmtui:"NetworkManager: Could not activate connection: Activation failed The Wi-Fi network could not be found" While im in the room next to the access point.
Some time ago i started noticing NetworkManager act up.
