SB6190 Keeps Losing Connection/Rebooting

Ever since I moved into my house, I've had issues with the connection dropping every month. I have a Ring Alarm system so I get notifications everytime the modem loses connection. It takes about 5-6 minutes before it comes back online.

 

For the past week, the connection drops have been happening several times a day. There have been times it dropped 3-4 times in an hour.

 

When it happens, the modem looks like it it resets itself. All the LED status lights turn off, comes back on, starts blinking, and eventually all the lights go solid and I have internet back.

 

The wiring from the pole goes straight to the modem. I removed all the splitters and replaced with couplers when I moved in because I used the coxial wiring for a roof mounted anteanna.

 

I have attached the status page. I'm concerned about the number of uncorrectables. What could be the issue.

 

I also checked the event log, I'm concerned that every time this happens, the device is rebooting because the event log doesn't show any events before the last time it lost connection/rebooted.

Can't see your pics. Since you are a new poster, they likely need to be approved by a Forum Admin. Or you may need to make a minimum number of posts.

You could try hosting them at one of those free third-party pic hosting sites and post the link to them here.

As soon as I posted a google drive shared link, the images appear to be working.

The upstream power is on the high side on channels 2 and 4 and it's at the very top on channel 3, and it may be intermittently fluctuating even higher to out of spec levels. That can cause random disconnects, spontaneous re-booting of the modem, and speed and latency problems.

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.

Can I get a reference to sources where I can buy high quality couplers and splitters. As of now, the cable from the pole is coupled directly to the modem. However, between the pole and the modem there is probably about 150 feet of coaxial. I can properly reduce this to 60 feet by re-running new coxial.

Here are some quality brand splitters that Comcast actually uses in different market areas;

Antronix CMC2002H 2-Way Splitter: http://www.amazon.com/Antronix-CMC2002H-2-Way-Splitter/dp/B001E4OH1E

Regal 2 WAY 1 GHZ Splitter: http://www.amazon.com/DIG702867-Regal-WAY-GHZ-SPLITTER/dp/B0018BQMUM/ref=sr_1_2?s=electronics&ie=UTF...

Extreme Broadband BDS102H 2-Way Digital Coax Splitter: http://www.amazon.com/EXTREME-DIGITAL-PERFORMANCE-CABLE-SPLITTER/dp/B007YV0UQW

Holland 2-way horizontal splitter 5-1000 MHz with ground.http://www.3starinc.com/holland_2-way_horizontal_splitter_5-1000_mhz-w-ground.html

Sv-2g 2-way Splitter 5-1000mhz: http://www.amazon.com/Sv-2g-2-way-Splitter-5-1000mhz-Sv2g/dp/B003TH36CK

The shorter that length of that cable is, the better it will be !
