Many of us have been there before - one or more DOCSIS cable modems init(r1) init(r2) stuck in one of numerous "init()" conditions - how do we interpret these messages and what do we do? A recent reader wrote in and had just this problem.

Mia Colabrese2021-08-18T09:53:33-04:00September 9th, 2011|

They were transmitting at their maximum transmit level. That being in a 16-QAM modulation with four bonded upstream channels.
