I have an Apple Airport Extreme right at the front of my house and an Airport Express at the back of the house to extend the network. The Apple Airport tool indicates they are working properly. I noticed that I was not getting much wireless signal at all on my iPad yesterday even though I was sitting next to the Airport Express. When I checked this, it confirmed that it was connected to the Airport Extreme at the other end of the house and obviously struggling with this. Should devices connect to the closest access point automatically, or is this something I need to set up? My iPhone seems to do this anyway, but other devices do not.
