I was trying to access Internet on a wired ASDL connection on a school network that simply wasn't working and someone with way more experience hacking Linux than I could dream of typed something for me and got it to work. But since then my Internet is unstable on all other connections! For example, my current wifi at a hotel keeps disconnecting the log-in, and that isn't happening on my cellphone's wifi.
This is the code he wrote, copied directly from the terminal:
I'm afraid I don't understand what he did at all! But can you tell me how to undo it?Code:benny@benny-laptop:~$ sudo -s [sudo] password for benny: root@benny-laptop:~# ifconfig eth0 192.168.1.111 root@benny-laptop:~# route add default gw
