when you reset, did you disconnect the coax from the cax80? so disconnect the coax, then power it on, push and hold reset for up to 30 seconds. Then power it off. Connect the coax back to it and power the CAX back on. One thing to keep in mind with the cax80 is that it'll go into a boot loop if it doesn't detect a connection from your isp to try to reconnect. So watch the led's on it and see if anything changes other than power led. did you get an rma from netgear already? how old is the CAX?
