Networking keeps stopping

My guess is that you are using DHCP on your network. The DHCP server is
responsible for supplying the entries in /etc/resolv.conf. Someone at
the server end probably deleted those entries. As you see, you can
manually edit the /etc/resolv.conf file, but when the DHCP client on
your machine refreshes, they disappear.
