Ragnor: I think the Thomson can be bridged but not from the GUI, I remember someone posting some instructions for telnet'ing into it and running the appropriate commands but I don't remember the specifics.
The other option is of course just to get a separate 5 port gigabit switch (~$60) and a separate 802.11N wireless AP like the one Cyril mentioned earlier or similar.
Cheerz for that! I think I found it
