My iPad keeps losing sight of my router. I'm on my PC and Fritz!box is still connected, and broadcasting wireless but my iPad can't seem it for some strange reason. When I restart my router it, once restarted it can see it for about 5-10 minutes but then losing sight of it again. Anyone know how to trouble shoot this as I have no clue. Don't know if it's the iPad being or fritz!box at fault. I've been using both of these for over a year without fault so that's why i'm not sure what's caused this to start happening today.
