Somewhere around 5:am this morning, all internet access was lost. Modem logs show 3hrs and 17 minutes of failed attempts to connect, ending in this string. 2014-07-24 07:35:47 6-Notice I401.0 TLV-11 - unrecognized OID 1970-01-01 00:00:22 3-Critical D003.0 DHCP FAILED - Requested Info not supported. 1970-01-01 00:00:12 3-Critical R002.0 No Ranging Response received - T3 time-out (US 4) 1970-01-01 00:00:07 6-Notice M571.1 Ethernet link up - ready to pass packets 2014-07-24 07:35:17 6-Notice M573.0 Modem Is Shutting Down and Rebooting... 2014-07-24 07:35:17 3-Critical R004.0 Received Response to Broadcast Maintenance Request, But no Unicast Maintenance o 2014-07-24 07:35:17 3-Critical T001.0 SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing 2014-07-24 07:17:02 6-Notice I401.0 TLV-11 - unrecognized OID 1970-01-01 03:17:05 3-Critical D003.0 DHCP FAILED - Requested Info not supported. 1970-01-01 03:16:55 3-Critical R002.0 No Ranging Response received - T3 time-out (US 4) Internet returned at approximately 8:30am.
