(EDIT at bottom.)

Having problems with my internet that don't look temporary.

Lemme explain how it's set up first so the problem makes sense...

Ok, so we have cable internet, that uses the same wire as the cable tv. There's the tv in the living room, a tv in my bedroom, and the cable modem also in my room.
The cable signal comes out of the wall of the wall in the living room. The wire goes to a splitter that has two wires - one leading to the living room tv, the other a really long one that goes to my room. The really long wire goes to another splitter that splits to the tv in my room, and also the cable modem.
The problem looks like it's the really long wire.
This isn't a small thing. It's gotta be over 20 feet in length, and it goes behind the 2 dressers in my bedroom (also my sister's room, hence there being 2), which are big and heavy, and just a pain to move. We would have to get some people from the cable company over here to replace the really long wire, and they only come out for appointments during the week. It is now early Saturday morning.

How am I connected now, you may be wondering?

Well, desperation to check my piling-up-messages kicked in, so I unplugged the modem and the router (we have a home network that lets the desktop and the 2 laptops share the cable internet), brought them out to the living room, unhooked the tv, and plugged everything in that way. I'm currently typing this from my 6-year-old laptop that keeps randomly freezing.

...Yea.

I dunno when this will get straightened out, so if I'm not around as much, that's why, cuz I obviously can't leave this set up I have going right now. >.>; I can only hope that it's not the really long wire that's the actual problem, and replacing the splitters with the exact ones we're supposed to have will work. Feels like hopeless wishful thinking, though. T___T;

Back to checking messages with bouts of freezing that require forced shut-down now..

EDIT: Well, my internet was dead all day yesterday, and I couldn't move the modem and router out to the living room. I'm only able to check my messages now cuz I'm at school. >.>; *checks to see the "damage"*
