Arris SB6190 Issues
Hi folks,
Hope I can find a better avenue of support through here then going through the motion of a power cycle 5 different ways.
Most recently I've had continuous instability issue with an Arris SB6190. Lime many folks I opted to purchase my own equipment vs. paying the monthly rental using Xfinity's modem/router combo. In the past the xfinity unit would occasionally fail but that occurrence was seldom, and for the most part held strong. I also had the triple play package and physical lines would use a splitter in the house feeding the internet and 3 rooms.....Again, line was stable. I've had the Arris (~8 months) it's been frustrating. I had a tech come out and during the line test indicated the splitter in use was reducing the signal. Since I had no use for keeping it inline, it was removed and the signal/stability were restored. This didn't lead to any issues with the exception of 1-2 reboots a week over the course of 2 months. Fast forward and I'm now getting a repeat of issues encountered prior to the tech visit. The event log on the Arris keep showing T3 time-outs which leads to the modem rebooting. This happens about 8x a day on average now. The bottom line I've witnessed since I switched to the SB6190 is quality suffering every packet of the way. I'm not sure I can chalk it up to the Intel Puma chips as the root cause, but hoping through showing my levels I can get some better feedback from the crowd. Thanks in advance everyone!

The upstream power is too high / out of spec. side That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
In an 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 5-1000 MHz, bi-directional, and no gold colored garbage from Radio Shack, Home Depot, Target, etc. Splitters should be swapped with known to be good / new ones to test.
Also check the coax cable for any damage such as cuts, nicks, kinks, sharp bends, etc.
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.
Good luck with it !
