Hello. I have the problem that some of my devices connect to the internet, and some do intermittently. I have a Time Capsule that I try to connect my MacBook Pro to wirelessly (that always works), but my PC isn't connecting, my iPad usually connects (but drops connection sometimes), my iPhone will connect only sometimes. Everything can always see the network, but they just all won't always connect. I also have an Airport Express, for iTunes, which only works about half of every day. It seems come evening time, it stops working. I'm at a complete loss. Thanks for any advice.
