IPAD vs Win7 vs Comcast 2go INet

Okay so here's a headache and once again I'm left blaming comcast.
I try for 2 days to share my usb Comcast 2go's internet with my ipad via an adhoc wireless network on my win7 laptop.

I could get connected to the laptop and ping it (grabbed an iphone app that lets you ping addresses) but could not get out to ping google or browse the web.

So came along a post today about Connectify, a little virtual router that would give better control than an ad hoc network. Several hours of tinkering, nothing, Connectify says there is internet access, but cannot reach anything/ping anything beyond the laptop. Even at some points the laptop lost inet.

My best guess is the comcast software you have to have running to connect/stay online.

Since Connectify was letting comcast bully it and not get it's fair share of the connection i tried another one. http://virtualrouter.codeplex.com/ Virtual Router.
Installed, asked me to name the network, give a password, and which inet connection to share. Set my Ipad to the new network and boom off and running and pinging google.
