widermouthopen Just wanted to update you. Had the visit from the "Network Specialist" today. As listed on his card, he's a 'Field Technical Specialist'. Really knew his stuff. He mentioned the fact that the old cable is severely out of date and is known for getting corrosion on the insides of the coax line. It's not UV protected, so I guess this breaks down the outer layers and allows things to corrode.
I guess he's the guy that gets called in when other techs didn't/aren't able to get the job done. He decided to run new line and clean up the cabling outside even further. Instead of running double splitter, he ran a 3-way with one line to each apartment. Ran new lines for the apartments that needed it. Good lord the signals are so clean now.
Here's my speeds now:
It's not much, but I bumped from getting a range of 270-300Mbps down with around 27 to maybe hitting just at 30 to these speeds solid on each test I run (varying servers and sites). Solid speeds that ramp up the flows much faster than before as well.
The signals are great. I'll post that at the end for you as well. Guy really knew his stuff and made sure that everything was looked at. Even installed a new faceplate for the coax connection just in case, haha. I'm signed up for some monitoring program now so that they'll have a stream of data for analytics and stuff directly from my modem. If it goes offline or if speeds drop past a certain point (or any other problems), then it'll send him an alert directly - so that's cool.
We'll see how things perform over the next couple days, but I'm pretty sure the problem has been fixed. He cut open a line for me, and it definitely looked nasty. Definitely most, if not all, of the problem that I was experiencing.
Also marked your assumption as the correct answer here. It was about people not wanting to get into the crawl spaces when it comes down to it (basically). This guy mentioned how after seeing one apt had a new line running to it, they should have thought to run new lines when they looked that bad. It really didn't take him all that long, either. Just about the will to do it to get the problem solved. He tested things out at the road, too.
All in all, it was the cabling under the house that nobody wanted to deal with. Good call.
