Getting the right location on my Gateway

I'm far from an expert on this, but it's a problem with the websites using your IP address to determine your location. This is standard practice, but I believe far from ideal and one that the industry will eventually have to move away from. T-Mobile's IP addresses have proven to not be very accurate for this purpose. I don't know if it's just that they have a limited number of addresses to utilize or if it's some other issue with their use of dynamic addresses. 

You can probably search the site for "dynamic IP address" or "static IP address" and get some suggestions. There might be a couple of options both of which have an added cost. First might be using a VPN service. Second would be signing up for a business account with T-Mobile and paying for a static address. You can also try rebooting your gateway to see if it assigns you an IP address that's closer to your location, but I imagine you've already done this plenty of times over the last year.
