hi guys im a bit confused at the moment as i have not been doing these cable modems since mine has been working fine for god knows how long. but i tried to do one for my mate and i cant get around it. when i boot up the modem with hyper t it just wont let me enter any data into the cm line. its a ambit 200 in nthell area and i have read a few threads about this update thing but i cant seem to understand what is going on. have searched around quite a bit before posting. and just for some info i dont get a nthell logo when i check the modem from 192.168.100.1. is my modem locked or can i still change the mac on it to get it working.any help is appreciated guys.
