I have installed Ubuntu 10.04 TLS - the Lycid Lynx onto MacBook Pro (specs). I have used it so far with wireless network and everything was fine until I have tried using wired network - it does not even seem to notice that I have plugged cable in.
I am no expert in Ubuntu hardware configuration and thus don't know what kind of information is needed to track the problem down and/or fix it. Please, feel free to request more information from me, but tell me explicitly what I am supposed to do (e.g. which commands to run, which config files to edit).
EDIT: Adding device info from
