Error Started Unicast Maintenance Ranging - No Response received - T3 time-out

Arris SBG6900 Errors. Speedtest looks great but actual response from browser is bad. Sling TV says I have connectivity problem and the APP barely works most of the time.

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

Re: Error Started Unicast Maintenance Ranging - No Response received - T3 time-out

The signal stats are good. Are there any more error log entries being shown than just those three ? If not, please wait some time and see if more accumulate, then post them also.
