Tom is having issues connecting his iPhone to his router, and he's looking to get an Asus One router. Leo says that's a great idea because it uses DD-WRT, which is an open source firmware and it's more secure, faster, and offers more options. Leo says that the plaster and metal joists could be acting as a faraday cage to prevent connectivity. And it's not unusual for a weaker signal to have issues in iOS. It just sounds like the signal isn't good and you coudl get an extender, but Leo recommends getting one from the same brand.
