Excessive splitters usually is a sign of ancient cabling as well. I know for a fact that Comcast has passive gain amps specifically built for dealing with homes that have more than like 8 tv's and a modem. You (or your dad, it's unclear) probably were hooked up a long time ago, or the tech didn't know what he was doing.

I am astonished. This is not a complicated issue. This is sensationalism. Before any of you "vote" on anything, consider exactly what it is that you're criticising. As it is, I'll bet almost all of you have never turned a wrench, let alone crawled into some ungrateful asshole's filthy attic or appalling, sewage filled crawlspace to replace a corroded cable fitting so said customer could spank his monkey at 3am to shitty cable porn, or worse, play farmville, and made < $15/hour doing it.

We are talking about a very delicate electrical system that cannot function effectively outside of a specific radio bandwidth before being completely overtaken by the numerous sources of RF which exist in the world. Remember radios? Well, they got their name because they were the receivers of "radiated" "waves" in the air. As were TV's. Guess what? That coax line in your house? That's the modern version of an antenna. CATV literally means "community antenna television". It's an antenna that you share with everyone on the same "node" of your cable system. It's shielded so the RF no longer has to go through the air. In effect, if there is a breach in the shielding around that cable (a long antenna), you're going to get noise, and crappy service. Additionally, your precious internet rides on the highest frequencies carried by this sole, frail copper wire. Those high frequencies, as any EE student can tell you, are especially highly susceptible to interference. A single dB can make all the difference for your highly calibrated, sensitive cable modem that you don't fully appreciate. Some of these networks are huge. If one of your neighbors got high and plugged a blender in, anywhere in his home, and he has frayed cable jacketing, anywhere in his home, or a bad fitting, anywhere in his home, it can easily take an entire block down. There are hubs, of course, but don't count on one being nearby, if you're tasked with repairing someone's internet. I get it, "fuck Comcast, they're the devil because I have to give them money", but let's be adults here. Comcast is people. Every company is people.

You're right. I was just trying to give some insight into why the quality of work varies so much.

Ah, sorry, I forgot I was on the internet, land of experts in everything.

Comcast is huge, and again, a lot of the techs are independent. Some of the employees, especially management are totally incompetent too. Ever been to the DMV? Now imagine that they're the ones hooking up your internet. That's Comcast.

Former Comcast cable technician here. I was an in-house tech, and corporate has ludicrous quality standards and nitpicky, white-glove QC's after an in-house tech leaves a job. However, the company obviously employs a TON of _independent contractors_. Some of these contractors are excellent at their jobs, but a lot of them aren't, and as they're not subject to any real oversight by the corporation, you really don't know what you're going to get. At least, this was the case at the office I worked out of. Based on my experience (and I worked at the company for a while), this is almost definitely 100% true, but it's probably a contractor or an individual corporate tech being lazy, instead of malicious action on the part of Comcast.
