There is an aerial cable that comes to this splitter (from the left) that splits out two cables. The one powering my modem is the one that’s damaged.
I’ve been having internet issues during the day for the last few days (I live in the northeast US, so very cold right now if that’s relevant). It’s only during the day. Internet speed is VERY slow when it’s connected (<10mbps download, <1 upload) and it is constantly disconnecting. But at nights internet is normal with no interruptions (160mbsp download, 10 upload). I had a tech scheduled to come out to fix the cable today but the guy never showed up (I could do it on my own but don’t fully trust myself with it) but it seems weird it’s only happening during the day. Is this actually the issue?
The other cable from the splitter goes nowhere, so is not an option. This is a rented house so there’s only so much I can do.
Yes. That and your splitter. Every split weakens the signal. It wasn't a huge problem in the days of cable. For internet, signal strength really impacts bandwidt, or speed. You want a direct line to the modem for best signal or an an applified splitter. If you also use for cable. You can find them on Amazon for fairly cheap.
That connection can be cut and fixed really easily as well. Just watch a YouTube video on how to do it. A razorblade will work if you don't have a dedicated coax stripper.
