I have an original iPad, an iPhone 4s, and an iPhone 5. All of these devices connect fine to my wifi. I borrowed an iPad 2 from a friend of mine today and I cannot get it to connect to my wifi. I don't now if the fact that the computer that is connected to my wifi router crashed has anything to do with it or not. While I was troubleshooting, I reset the network settings on my original iPad and now it won't connect. Here are the things I have tried: powering down the iPad, resetting the network settings, and restarting the router. The router isn't that old - just a couple of months - so it should have the latest firmware on it. Are there any other suggestions?
