The 3 connectors look corroded and the terminator even worst, It also looks like there might not be a stainless screw in the bottom hole and a lot of corrosion, if so it needs to be replaced as well.


 I took a 'close up' pic today from my side of the fence.

Looks like the bottom screw is there.  But some of the other stuff doesn't look so great.  My tap is top right.

 

Again and FWIW, for a high rez zoomable of this pic go to my google photos link and scroll down:

Modem up ~10+ days last time I was able to connect to the SB6141's embedded webserver this a.m.  Further browsing to the SB6141 started failing early afternoon today so 'Signal' and/or 'Log' collection no longer possible at this time, thus not added to this post.  DS speed still ok at the moment.  No change of the LED display on the modem thus far so I'm just going to let this SB6141 run and see what happens next!

Re: Yet another SB6141 related issue?

Connectors don't look awfull, the terminator looks terrible, unknown what shape the internal, non floting actual terminating resistor looks like

, I'd suspect the connection on the other side of the amp, but it should affect everyone on your tapoff and to the right of it

Re: Yet another SB6141 related issue?

The SB6141 ran uninterrupted for ~17 days.

 

Had to reboot the SB6141 yesterday.  LEDs look 'normal', (solid blue Receive (DS), solid blue Send (US), solid green Online, flashing blue Link.  No hint from the LED display that there was trouble.  As is usually the case I didn't lose Internet, but browsing slowed way down.  Did a couple of speedtests, speedtest.net showed 0.55 Mbps down, 11.71 Mbps up, dslreport's speedtest:  3.28 Mbps down, 3.73 Mbps up.  (Speeds when all is well are normally in the range of 100+ Mbps down / 10+ Mbps up).  I was able to login to my TWC account to troubleshoot the cablemodem which indicated that the cablemodem was not connected (red dot).

 

Anyway.  Like I just typed, rebooted.  It's been up 24 hours now so I'll post Signal and Logs.  Times are off by an hour, times shown are CST.

Re: Yet another SB6141 related issue?

This issue continues...  Cablemodem rebooted on it's own earlier this a.m. and again this afternoon (Tuesday, 07/14/16).  This afternoon was when I notice loss of Internet connectivity but didn't check the log until a few minutes ago.   Signal and Logs follow.  Logs are CST.

 Partial DS=  still have ingress, my gut feeling is it's this connecter, the aluminum hardline is broken under the glue filled shrink thanks to no strain relief doglegs and the neighbors drop tugging on the messenger in the wind.

This takes the bucket truck guys to fix, eventually the center wire will break taking out service completely.

The iside stuff has reduced the problem, not eliminated it

 

 

Modems don't have ingress issues, especially the 6121,41,83,92, it's a coax issueWoman Sad

  If all connectors in the house are new and tight, it's outside somewhere. nothing you pulled and pictured looks bad! BTW, when you do compression F's, you leave the foil intackt, but fan out the braid back over the black insulation so the the connecors inner ferrule slides between the braid and the foil

The white dielectric foam will then come up to the inside of the threaded nut.

 

Probably this:

 


STILL SAY THIS CONNECTION NEEDS TO BE REDONE, I FEEL THE ALUMINUM IS BROKEN, INTERMITTENT. IT'S INSTALLED WRONG WITH THAT DROP BEHIND IT ADDING STRESS TO THE MESSENGER.
