Q: Ipad apps won't load when connected via Comcast wifi

We are trying out Comcast for 30 days. We already had Uverse so right now we have both. When connect via Uverse everything works fine on my iPad as always has. Internet access, apps load etc. when I switch over to the Comcast wifi, I can access internet just fine. Sped test are all hella fast. But for some reason a few of my apps/games won't load. for example I have a price is right bingo game. It will not load when connected via Comcast. I get an error that say it won't connect and to check my internet access. and my internet access will be working fine.  If I switch back over to uverse the game will load.  There are a couple other apps doing the same thing. Anyone seen this before? I have an iPad Air 2 on iOS 8.1.2
