Hi Guys, I managed to get one of these for pretty cheap. I've now realized that this router has only 1 ethernet port on it (fast ether), is there any compatible NM for this unit that will provide an additional FE port? NM-1FE-TX could do the job, but I have been reading that this module is NOT compatible with the 2600 series at all. Any thoughts? I would like to use this in conjunction with my cable modem, but having only 1 ethernet port is a pain. Now I wish I had bought a 2621 (which has 2 FE's).
