My home LAN is set up with fixed IP addresses and an Untangle gateway/firewall/DNS server with Internet access.
One of my computers (Ubuntu 10.10) will connect to the Internet only through the wireless, but reports "network is unreachable" when connected to wired. Even though it will not connect to the internet, it will connect to other computers on the LAN, including the gateway when using the wired connection..
My laptop (11.10) and another system (10.10) connect either way.
I use the same IP address for both wired and wireless on the same computer, and always disable wireless when using wired. The laptop uses wicd because Network Manager fails on it.
I would like to be able to connect to the Internet using wired connection, how can I do this?
