How can I reset all network settings in Linux Mint?

Solution 1:

You aren't really clear as to what you've done, with what privileges (root?), or what the consequences/problems are.

Anyhow, try (re)moving: ~/.gconf/system/networking/

And if it doesn't work, try: /etc/NetworkManager/system-connections

If it is NetworkManager related. If you played with ifconfig and other tools, take a look at:

/etc/network/interfaces

To be sure the changes take effect, the best option is to log out and log in again, or reboot if you changed anything in /etc . Good luck!

Solution 2:

try renaming the folder called ".gconf" in your home folder, (this will reset some OS user-made changes) then log out and back in. dunno if it will solve it, but if it doesn't, you can rename it back and restore your settings.

aamof, the network settings are not focused on a single file, but distributed among several, working together.
