Got my RT66U last week and it took an hour trying to get a IP address from my cable modem. Finally got it to work, and over the weekend I was had to clean up some wiring. Unplug the cable and again I couldnt get the router to connect to my modem. I had to re flash to Asus stock firmware in order for it to connect (get a ip address) This morning the cable guy come out and was working on the cable box (TV) and had to unplug the router from the modem to work on it. Plugged the modem back and no internet connection. Could this be a bad router? dont know why it keeps on losing the ip address. Ever had an issue with my previous router.
