Before today, I've never been able to get my modem to connect without using my signal amplifier, even though I'm not using any splitters.

Today, my internet started having problems and intermittent connection for a few hours, then no connection at all. There were no outages reported in my area.

After doing the usual steps of re-seating all the connectors, unplugging, etc. and nothing working I decided to take my modem outside and connect it directly to the cable coming from the street and it worked.

To make a long story short, I continued troubleshooting until I bypassed the first coupler by using a standard household barrel connector. Problem was solved and for the first time, I could get my modem to connect without going through an amplifier.

Has anyone had this happen before, or can anyone tell me what is going on with this? IMG_20220912_220155659~2.jpg
 
I believe that's a grounding block or a lightning arrestor. Was it floating, or was it grounded?

The cable should be grounded to the house electrode, but I don't know if doing that could cause the problem.

You could try temporarily jumping the new coupler to a ground and see if the problem returns.

Sometimes, and I'm not saying it's the case here, that first barrel is a filter to keep an internet-only subscriber from getting the TV channels. Could be it was old enough to also hit the channels being used for data.

Actually, what's in the foreground on the right looks more like a filter.

That's interesting, I should mention that the house came with a direct tv satellite dish that was never connected since I bought the place.

It does have a place to bond to the grounding electrode conductor, but it was never bonded

No, that is the two ends of the cable connected with a cheap barrel connector
 
Could be a filter as others mentioned. Also, every time the satelite guys come here, they replace all my feed thru's with theirs. The older ones had 1 GHz of bandwidth or rating. The new ones are 2 GHz. So maybe that old one couldn't pass the frequency band being used, or pass it very well due to bandwidth or a filter.
 
If anyone is interested I found it.

Good call, there was a PPC brand amplifier model EVO1-9-U/U

It must have came with the satellite dish. The filter ground block and amplifier are now bypassed and everything is good
