If I reboot my router (Netgear DGN2200) Ubuntu 11.10 Server does not reconnect to the network. This is over a wired connection and I have tried it with both a reserved IP Address over DHCP and a static IP Address configuration as follows:
# The loopback network interface
iface lo inet loopback
# The primary network interface
iface eth0 inet static
Both connection methods fail after a router reboot i.e. no ping, no ssh, no http. I have never had to do anything special to ensure reconnection before - but am I missing something?
