I just switched back to Comcast at the house. We had it for a long time years ago, but then it got really unreliable and we finally were having problems with it so often that I just couldn't justify keeping it. Also, in our area, Comcast was the only >1.5mbps service available. In fact, at the end of March they're talking about increasing the bandwidth in the plans to 4 and 6mbps, which will be pretty tasty. The up-stream on the 6mbps plan is about what we've got on our current DSL, at 768. The DSL says it's 1024, but that's ATM cell rate, and so real bandwidth is around 80% of that.

It's kind of hard to find the information on what you have to do to register after you sign up. Here's what I did to get set up.

I used Firefox and also tried Konqueror, but Konqueror wasn't working for me. You need to go into the proxy set up and set HTTP and SSL proxies to “sas.r4.attbi.com” on port 8000 (not 8080). Note that this is for the Denver, Colorado area. Your installer should be able to tell you what proxy you need to use, ask them.

In the proxy configuration, set up the proxy host name itself so that it is excluded. In Konqueror, there was an “add” button where you could add exclusions. In Mozilla, there's a “No proxy for” field, and just add a comma and the proxy name to this.

If you are using a temporary device to do the setup and you actually want to use a firewall for the final connection, set up your laptop or whatever so that it has the MAC address of the final card you want to have access. You can find the MAC address on a running machine with “ifconfig”, and you can set that MAC address on another card using “ifconfig eth0 hw ether ”.

Start up dhclient on the Ethernet interface. You should get an address.

Use your browser to go to “https://” followed by the proxy name you got above.

The installer will be able to give you the account information, etc. Follow the pages on the screen.

Note that if you are able to load the first few pages, but then it sits at “Connecting to oai.comcast.net”, it means that you didn't properly set up the proxy. If you cannot connect to the URL at all, it means that you didn't properly set up the “No proxy” host name as mentioned above.
