There is a splitter that connects my cable modem and capture card to the cable line. Recently, my cable modem has been dropping connections. When I take the splitter off, and do a direct connect, the cable modem drops less connections. I tried a different splitter already too but same thing happened. Also, there is a connecter to join two cable ends together. I felt that last week and it was really warm.

So is this a cable modem case? I don't think it is the router right? This happened to me 6 years ago so I replaced the cable modem at the time. Does cable modem have to be replaced every once in a while or something?

Thanks
