Intermittent drop outs

I have a surfboard SB6183 with no spliiters, internet only that gets multiple errors at least once a day. Doesn't always cause a reboot just loss of internet. It can go for days without an error.

Let me know what I can do. Customer service says everything looks good everytime I call in.

Here is the logs from the last couple of days:

Re: Intermittent drop outs

The upstream power too high and it may be intermittently fluctuating even higher to out of spec levels. It's already out of spec on channel number 3. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.

In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.

Re: Intermittent drop outs

I took apart and reconnected all the connections. Xxfinity tech said to call Arris. They had me do a factory restore, brought all the upstream levels too 46.0 dBmV.

Today all the levels are 

ChannelLock StatusUS Channel TypeChannel IDSymbol RateFrequencyPower
1LockedATDMA45120 Ksym/sec36500000 Hz47.9 dBmV
2LockedATDMA15120 Ksym/sec17300000 Hz48.5 dBmV
3LockedATDMA25120 Ksym/sec23700000 Hz45.5 dBmV
4LockedATDMA35120 Ksym/sec30100000 Hz48.5 dBmV

 I have had more T3 and T4 timouts

Can Xfinity lower the upstream power levels?
