Comcast Nightmare...someone wake me up!

Alright, I have a serious problem with my internet connection and it's been happening for the past 3-4 weeks. My connection will drop anywhere between 5-10 times a minute for 2-10 seconds. I go from a 55 ping to 999 during that time. The lights on the modem do not change and it appears that I am still connected to the internet although I get no activity. This happens around 2000 times a day and it is driving me insane. I can't play online games, can't use Skype, or watch Hulu since it will freeze/drop me every few seconds.

I did a trace route and the problem is occurring at the 2nd hop, the one after my router but the IP does not match my modem (however it is very close). I have tried everything I can think of. Power cycled the modem, removed the router, turned off my firewalls, etc etc. The problem occurs on all 3 of my machines so it is definitely a network/internet problem.

I called Comcast and they sent out a tech who looked at my modem and the lines in my house and he said he was getting errors on his equipment but could not fix it. They are sending out a line tech tomorrow or Friday to take a look at it but I don't have much faith in them due to past experiences.

Situations like these usually resolve themselves over time but it's been almost a month now and I would appreciate any advice anyone could give me.

Thank you,

Kevin
