While back I changed the password on the modem after 10 times been using the default cusadmin for Username. Enter highspeed or CantTouchThis for Password.
We have 3 DVR hooked up to the modem. one of our DVR went bad and we got new one and as far as I remember for sure my password it will not log me in no matter what I put in for password.
I even tried the default password and it didnot work.
I do not want to reset the modem because I will lose all port forwarding with my good DVR that I already have it hooked up. The company that make those DVR have set them up the first time as courtesy and it did take long time to set them up.
