Ubuntu Installation Troubleshooting

Loss of Network Connectivity

Double check your network settings with ifconfig and route -n. These should be the settings that you use in the installation. If these are not correct you can change the ip address by issuing the command

sudo ifconfig eth0 192.168.1.14 netmask 255.255.255.0 up

assuming 192.168.1.14 is your IP address. The route can be changed with

sudo route add default gw 192.168.1.1

assuming 192.168.1.1 is the address of your router.

This is especially important if you are doing a headless install
