A really old splitter probably has too narrow a range and may not be bidirectional.Splitting a signal does weaken it significantly. Too many splitters in the house can cause your symptoms. I don't know how it's best to do this with phone service, but with just cable TV and Internet service, what you're supposed to have is one two-way splitter near the entrance to your house ("two-way" means one input, two outputs), and one of those outputs goes to your Internet cable modem and the other output goes to one additional splitter that then splits the signal to all the cable TVs in the house (which would include your PC with the tuner card). NO OTHER SPLITTERS. Each time you split, the signal gets weaker, so you have to minimize splits. Some people have additional splitters in their house, like they'll run one piece of cable up to the second story of their house, and have another splitter there to distribute the cable TV to all the second story TVs. Then On Demand doesn't work, they see "THIS CHANNEL WILL BE AVAILABLE SHORTLY" on a few digital channels, they have pixellation problems. People who try to split away the feed to the cable modem to TV sets can end up with both not working. So since you're having problems, I think you may need to take your feed to the TV tuner card on the PC not from the cable modem area, but from the TV side, which means you need a new arrangement of splitters and cables.Again, how the Comcast phone service ties into that, I don't know, because that's not something I have any experience with. You may need to have a three-way splitter near the entrance to your house, and send one feed that goes off to all your TVs (including the PC), one feed that goes to your phone service, and the third one goes to your cable modem. But a three-way splitter makes the signal weaker to all the branches than a two-way splitter does. So maybe that's wrong. Maybe you need to take the phone service from the cable TV split, and only use a two-way splitter.Another thing to avoid: don't use a splitter with unused ports. If you need to split a signal three ways, use a three-way splitter, not a six-way splitter. Unused ports weaken the signal too much.For a long run of cable, you want RG-6 or RG-6/U, not RG-59 or RG-fifty-anything-else. Old cable may well not be RG-6. You should see small white print on the cable telling you what it is. If you don't see it, I would be suspicious about it, as it might not be up to specifications. The other thing is that the connectors need to be tight, not just on the devices they're attached to, but on the cable. Make sure you can't pull the black cable out of the metal connector at the end of it when the connector's attached.
