modem trouble

[starship_troopers]

Ok, first off thanks in advance for help.

My cable modem that i have from cableone is on and running, but every once in a while the activity light will shut off and i lose connection. this happened since a storm last night...I had everything unplugged except the cableline to the modem, but the modem ittself wasnt connected to the pc so it was isolated just incase it got hit. I have it all plugged in and connected now, and have tried troubleshooting from the ethernet cord to the drivers on pc. any ideas on how to fix this?  later today i will call cableone and have them do some tests to see if it is my modem or something on their end. (btw, the cable line running to my modem is straight from the box outside, there are no splitters or anything and it is a seperate line than what my tvs are connected with.)

edit/ while checking my email in outlook express, after trying multiple times because of disconnections, it took me like 3 minutes to connect to mail.cableone.net which is the mail server for my isp. and this is on a 3mbps download package....it has to be on their end right? but when i do a speed test here is the result
