I have a cable modem and about a year ago I just started losing connection. My television signal was fine just the internet connection went out sporadically for hours. I ended up calling my ISP and they sent a guy out and he said it was the either the connector or the splitter and replaced both. I was dubious at this answer. This was after 2 years of it working fine. How can a nonmoving conductor just go bad? Now a year later I'm having the same trouble with the splitter he installed so I removed the splitter and the connection is just fine. Did I just get a cheap splitter or do they just eventually all fail?
Difficult to tell, isn't it? I suppose, like everything, they all have a shelf-life. Everything breaks.sooner or later. It happens.
Well if there's a lot of humidity in your house it can slowly corrode. Also if it's a powered splitter, and made from cheap parts, all the heat can slowly burn out the circuitry. And with the cable companies, there is a very good chance that the equipment they give you is used.
Honestly , the splitters can corrode a small bit inside, and that is all it takes to ruin the digital bands used for internet, and not effect the televisions signal in the slightest, especially in high humidity enviornments!
My heavens, I never have been flashed, but I did unintentionally flash a few folks once. I was in the hospital some time back and decided to take a stoll to the vending area. Well, I wasn't thinking about what I was wearing and, let's just say that those hospital gowns don't leave a lot to the imagination on the backside. The nurse came up from behind me and put a blanket over my shoulders . . . I was wondering why it was a little drafty back there!
Yes and no, if you purchased an over the counter splitter from say walmart, it was more than likely a 1000mhz which is very bad, you want a 5-1000 for some room to play. I have seen a bad splitter remove a single channel from a tv before because someone got it at the local radio shack. The same goes for RG6 connectors, they can all go bad over time and require replacement. I change mine out every year. What interferes with your internet is noise, and if you have a leaky fitting or spiltter then you're ingressing noise which can cause your modem to unsync. One way to check noise in your modem is to login to the docsis of the modem and check the SNR (signal to noise ratio), typically the higher this number is the better. If it's below 30 that's considered bad. Another thing you can check is the upstream and downstream power levels. The upstream should be some where below 55dbmv, if it's higher then it could be a node issue, or a local tap issue. Here we like to see the return level at the modem around 45dbmv.
