I've been getting a lot of error on my modem lately, it's a SB6180 on TWC. My signals seem fine so I went ahead and attached the modem logs, I'll attach the signal levels in just a second.
Notice (6) TLV-11 - unrecognized OID Error (4) Missing BP Configuration Setting TLV Warning (5) DHCP WARNING - Non-critical field invalid in response Notice (6) Honoring MDD; IP provisioning mode = IPv4 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out
Although there are a bunch of entries, there's not that much going on. It looks like on 7/8 there was a minor outage, A period of around 12 minutes (0:05:34 to 0:17:02) where it couldn't sync.
You then had a power outage, or power cycled your modem on 7/15. You can tell from the 1970 date that the modem lost its current date, which usually only happens on power-up. Looks like there were a couple other T3 timeout resyncs/hiccups on 7/18 and 7/19, could be TWC working on something.
There aren't enough events here to worry about. If you start seeing the same thing every day, around the same times it'd be a little more worrisome.
