My WRTP54G just arrived all the way down here in Bogota, Colombia. But when I plug the modem into the internet port, I get no link. No lights, no connection, no nothing. Different cable? Still dead. Same cable, different router? Works great. Same cable plugged into one one of the LAN ports? Link! So it's not the cable. Nothing I plug into that internet port will connect. So now what do I do? Shipping this thing back from Colombia means another month of waiting. Is there anything more I can try to make this thing work?
