Default Electrical Interference on Cable Internet???

Howdy all. I recently upgraded my internet connection from dial-up to
high speed via cable (about time, I know). Since installing the cable
I have been having problems getting connected to the internet. If I
connected the modem straight to the cable drop coming in the house I
would get a good connection, but when I run a cable from the drop to
the computer (about 25', no splitters) I would fail to get a
connection.


I have cable internet, which works well. I put the modem as close as I
could to where the cable enters the house, and ran ethernet (CAT5)
cable the rest or the way. Also, CAT5 is easier to handle than coax.

Sometimes it would connect, but most the time it would
not. So, I got to looking at the cable run (finished basement, drop
ceiling) and discovered that in two places the cable was running along
side and sitting right on top of some romex. Hmmm, I thought to
myself. Could I be getting interference on the cable from the romex?
So, I moved the cable several inches away from the romex and low and
behold a got a good internet connection.

I have a cable guy coming out later this week to check my signals so
I'll ask him if the electric lines could cause enough interference to
affect my internet signal. It appears so and makes sense to me
especially if the cable is right on top of and running parallel with
the romex. Has anyone had any similar experiences?

And (once you get a good connection) there's other things to worry
about. An inexpensive router between the cable modem and the
computer(s) is a good idea, even if all you have is one computer.

You can ask the cable company about that (SOME are helpful that way),
but there's really no need to. It's YOUR network.
