Disconnects at random times.

[shintx]

Hey, I've been experiencing weird disconnections for my internet at random times. My internet sometimes goes off for like 2 secs gets me disconnected then comes back on. My current isp is Roadrunner and i've called them a couple of times and they said that there are no errors with roadrunner.
I run a router for 3 comps (including mine). I use a D-Link model. In my thoughts i think that either my ethernet card or network card ( or are they the same.. )


if any1 knows what may be causing this, help will be appreciated
