said by robman50:Also what do all those DOCSIS errors/warnings up in that log above mean?
A T3 ranging error occurs when the CMTS isn't responding to maintenance (ranging) requests. What it isn't telling you is it probably retried minutes later and was successful.
A T4 ranging error occurs when the CMTS says it's about to send a new set of maintenance parameters and they never get received.
The DHCP errors indicate there is extraneous information in the DHCP parameters sent to the modem, which is usually harmless.
TLV-11 - unrecognized OID indicates that there is a SNMP parameter (OID) being requested that is unsupported by the modem.
