This problem began only a few days ago for me. The problem is, it only seems to affect apps that need Internet access. I can surf the web, download from web sites, etc. but my Windows games won't log into my Xbox account, and worse, Windows update doesn't work. Just keeps running. This occurs on both my PC, and my tablet. I'm still in build 10130, and have had it since it was released to the fast ring, yet the problem just started a few days ago. I don't have a problem like this with my Android phone or tablet on the same network, and my Roku box also works fine. Hope someone here can help.
