If you don't have anyone tech savvy enough to do the remote setup process for you in CT, get someone to install the free logmein software on a laptop or computer either at your house or from a friends laptop. Get them to sign into your CT home network. Take over their computer remotely. Run the sling software setup. When you get to the point where you manually port forward the settings, sign in to your router and change the settings.
The above is just a guess on your AT&T router info. Once you've done the port forwarding, finish the sling setup. Hopefully, you'll be successful with remote viewing after that.
Free software, just create an account
You won't be able to do it remotely, so the above is my only suggestion. The alternative is having someone you know do it for you in CT.
