Check the type
of cable in your run as that might be
part of the problem.


And the quality of the connectors (and their installation) is
important too.

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. 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?
