Twelve days ago my SB6183 rebooted at 1:24am. In my router log I can see that it was off-line for about 20 minutes. When it came back online I had twelve Downstream Channels bonded; I had eight Downstream Channels bonded the day before. What concerned me was before this event I had very few or no Corrected and Uncorrectables but now I was seeing very high Corrected and Uncorrectables on five Channels in less than 8 hours. Since this happened I restored the factory defaults and rebooted the modem several times. The Corrected and Uncorrectables are not as high as before but they are there. There are no issues shown in the Event Log other than DCHP renewal and "Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out" once a day.
Also, I used to have four Upstream channels and now I only have three. Is this a normal change when going to more Downstream channels?
I have attached a screenshot of the modem status five days after I last rebooted it. Also, since going to 12 downstream channels I see that the downstream power on all channels dropped from ~0.0 dBmv to -2.5 to -4.4 dBmv. My speeds are OK. I checked all the coax connections and they are fine. Do I have a problem? What could be causing all the corrected and uncorrectables on the higher channels?
