Edit: Solved. Did a timeshift restore to one before I made the network changes. Everything works fine now. Definitely a problem with Mint XFCEs network manager though and something the devs should look into.
Linux mint 19 user here
Setting a new router after last one died a week ago. But when I enter 192.168.0.1 as said on its manual, it won't work. I'm getting an error saying 'this site is unreachable. Err\_address\_unreachable'. Network manager new connections are completely grayed out as well. What do I do?
P.S. : before the WiFi arrived, I connected the cable directly to cpu and had to struggle a lot to get the thing to work as can be seen here https//www.reddit.com/r/linux4noobs/comments/9ecinn/network\\\_manager\\\_grayed\\\_out/
Edit: I did
Sudo service network-manager restart
Now the error message has changed to 'no internet'
