Yes, the lines the run to your modem need to be taken care of much more carefully than your tv lines.
The most important thing is to have your modem connected to the original splitter. Two splitters will work sometimes, three will almost never work.
Perfect signal for a modem is 0dB. Anything under -5dB wont work; and anything over +10dB is bad for the modem.
The second most common problem with modems are bad fittings. All of the fittings in the line from the tap to the modem need to be perfect. Otherwise your modem is going to drop packets and possibly lose sync with the head end.
Other problems can be caused by nicks, cuts, kinks, or twists in the line. Significant amounts of signal can be lost even if the line is stapled or screw-clipped in equal segments. You can avoid these things by having your installer run your cable in the walls. It might cost you a little extra, but it looks nicer and your cable will last longer.
The best tip I can give you is make sure your installer knows what the fuck is going on. If you see him wandering back and forth countless times, ask him whats wrong. Don't get in his hair though, because then he WILL do a shitty job on your install. Check his work after he leaves though.
Good day all.
