Home Location Keeps Dropping Every Time IP Address Changes

Our internet IP address changes often. We have Windstream internet service. Direct TV Stream requires a static IP address, otherwise, our Home Location keeps dropping whenever the IP address for our internet changes. The problem this causes is we can only use two TV's at a time (rather than our three at the same time) until our Home Location is reset. Direct TV will only let you reset the home location 4 times in a 12 month period. They have actually reset it after 4, but it requires calling them and it usually is a process where they want to go through a very lengthy process before they realize what they have been trained to do does not resolve the issue. Very few technical support people understand the problem and it usually requires a lengthy explanation and them getting in touch with a supervisor (and waiting on hold for them for several minutes) before they will come back and reset the 4 resets to zero.  I am on the phone now with Windstream to see if they can offer a static IP address. However, I understand that if they do offer it there may be a monthly fee. Good grief. This is ridiculous. Direct TV should not have a four reset limit if they aren't going to fix the problem. Has anyone else experienced this?
