Yes. Splitters are #1 culprit.

Yes. This will cause issues. I had a similar setup at my house because I thought it’d be great to have the option to Switch internet providers any time I want. Unfortunately things didn’t work out as I had planned so I ended up unplugging the inactive internet provider, but labeled it so that anyone could easily swap providers in the future if they desired just by swapping cables.

No longer water tight. No drip loop. Guessing you have moisture in you jacket creating resistance. Replace entire length of cable. Water could have ran yards inside. Next time demand a drip loop to prevent ruining entire lengths of cable.

Yes, and that splitter has seen better days as well. Wouldn’t be surprised if it’s not full of water.

If it gets wet, it could definitely be an issue. It's actually an easy fix if you google how to crimp coax cables and buy the tools to do it. I mention this because that cable may be a long run and difficult to replace. If you're going to do it yourself, it's a 5 minute job to cut that end off and recrimp and new coax end on it, with maybe $20 in cost to buy the tools needed and connectors.

This could very well be a problem. The past issue I had with my internet it was dropping heavily in the morning only. ISP came out and my ground level box had a knick on my line for the drop and what was happening was the condensation in the morning from the grass was building up on the line and causing water to enter the knick on that line.

Sounds like what you are describing with a similar looking issue on your line.

If you're going to replace that connector/cable, also replace the splitter. My cable company just replaced mine and resulted in a better connection.

Absolutely. Its jacket is damaged which means it can now be compromised by moisture which alters the signal properties of the cable. Also looks like it was kinked tightly which can damage it.

Yes, I just went through this. Was having internet dropping out multiple times per hour. A couple of years ago they ran new to the house. They did something in the rap out front but ultimately we traced it to a bad cable in a wall from a previous homeowner. The had extended to cable to the wall using a un shielded crap cable.

Interference could be getting in the line. If you aren't using the other cable for anything you should replace the splitter with a barrel connector and increase your signal strength to your modem.

absolutely, and it's also not even grounded. See that rusted nut? That's where the ground connects.

That damaged cable line is most likely causing massive ingress. Get that replaced ASAP or the cable company might block you off at the tap if they find out the ingress is coming from your home

I had a very similar situation when I used to live in Belmont MA.

I had DSL and was good in the afternoon and evening but early morning the connection speed was atrocious. After numerous calls to tech support and 2 techs coming out there was no solution. The replaced all the outside cabling and inside devices.

Finally an IT guy at work who lived a couple streets over told me to ask about the line from the pole to the house. Turns out it was dropped 40 years earlier and had cracks all over the sheathing allowing moisture that collected late at night to seep in. That killed my morning connection but by midday on most days it would dry out enough to work. Once they dropped a new line I had perfect connection.

That most definitely could be a problem. Moisture could easily enter the cable end.

Wouldn't cause any issues if you Fiber (FBTH), DSL, satellite, or mobile 5G. 😉

Can you log onto the web interface of your cable modem and report the signal levels? We had issues for years where it would be fine and just go poof. After about a year of calling twice a week they sent a crew out and they cut every connector off of every wire and replaced them, looked, and were it is fine now. Um it was always fine til it was not. And they were no sooner gone when the signal went away yet again. Months later they sent another guy, on his own, to shut me up, and he looked and found the issue in about 30 seconds and I am not kidding. They had a heavy wire wrapped around the cable where it met our eave and the nail they had it tied to pulled out so the cable was bent at a sharp 90 degree angle and sometimes the ends pressed together and sometimes not. He ran a new wire from the pole to the house but he did not have a bucket truck so it was on the ground, he was going to come back in a week or so to fix it. Two weeks later I called and he was no longer with them. It took and I am not kidding two years to get the wire back up in the air. They came out and fixed it and like a month later Verizon ran Fios out here and we have not looked back. Oh, the old company began with Z and ended with O as is O star reviews for their service.

Yes, ingress and egress. Needs new fitting
