Error on Netgear device: Started Unicast Maintenance Ranging - No Response received - T3 time-out
I am receiving these 5 errors on my Netgear C6220:
- 16 consecutive T3 timeouts while trying to range on upstream channel 1
- Unicast Maintenance Ranging attempted - No response - Retries exhausted
- Started Unicast Maintenance Ranging - No Response received - T3 time-out
- Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out
- MDD message timeout
These are causing my router/modem to lose connection to the internet & requires that I power-cycle the router. Happens every 2 hours or so. Is this an issue with the service or with my router? Thanks for your help!
**EDIT** A tech visit failed to solve the issue & the corporate employees refuse to answer my messages now. I am losing connection at least 10x/day, making the service basically unusable. All be warned who are having similar issues! I will be switching to the city broadband the second it's available in my neighborhood.

The stats are o/k. Would you please also post the error log entries in their entirety.

Even though the signal stats looked o/k at that snapshot in time, the error log entries confirm that something is going on. Perhaps there is noise ingress into the line(s) somewhere.
There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.
I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They can check the CMTS (Cable Modem Termination System) for any real time degradation and / or error reports, see your node / cable plant and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and poll for those upstream receive signal stats.
You should get a reply here in your topic. Good luck !

Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
