I have installed Ubuntu for the first time (version 11.04), finally making the step to open source software. Everything seems to be working fine, however I can't connect to my router via a wired connection.
I can use the wireless network, which was detected and I could connect by giving the code. But when I try to connect to this network by wired network, it tries to connect and it says "connection offline" after a while. It never establishes a connection. I used the standard automatic DHCP settings of eth0. I never got this problem with another OS and it's not the cable that's not working.
Does anyone know how to solve this problem?
I'm using a Fujitsu Amilo-something laptop and a Siemens Gigaset wireless router.
