Just installed SB6141, Now appears that I am connecting from across country?

Nah, your traffic is being routed normally. Speedtest.net (and speedtest.comcast.net and many other websites) use third-party geo-location services to try to determine your location, and as you've discovered, they get it wrong sometimes. Comcast doesn't officially provide geo-location to anyone; they change IP address blocks so often that it would be a headache to maintain. Third party companies try to give a "best guess" as to your location. If you're interested, here is one geo-location service. They offer a form on their website you can fill out if you want to update your location; in my experience that can take a while. Here's the link:

For a more accurate speed reading, try manually selecting the speed test server close to you.

Hello jpvaughn and welcome,

Your Downstream, Upstream  and SNR all look fine. Make sure you are measuring your speed test directly with Enet cable connected to a computer to your Customer Owned Modem (COM) because that's where Comcast guarantees your internet purchased speed.

Hope this helps you out.
