So I have a Motorola Surfboard 5101 that's being fed interwebs by Cox Communications (unfortunately.) The internet has been dropping once or twice a day for the last month or two. I called Cox tech support and they said that it's probably the modem shutting itself off.
So I checked the logs and I see "Received Response to Broadcast Maintenance Request, But no Unicast Maintenance o" and some Googling came up with "received response to broadcast maintenance request but no unicast maintenance opportunities received" as the full message.
Sure enough after the entry in the logs the modem reports that it is "shutting down and rebooting."
Does anyone know how this is caused and/or how it can be alleviated?
