Hi. Sorry if this is the wrong place to post this. The problem I have is with a MacBook Pro, an iPhone 4 and an iPad. The moment I turn on the wifi on any of them my router starts flashing like crazy as it would seem that lots of data is being transferred. On the MacBook Pro I noticed that its transferring large amounts of data. This is slowing down the connection for web browsing. The data is transferring even when I have all Internet apps closed. The only thing I can think of is that all three devices are tied to the same iCloud account and there is an Apple TV 2 in the network. Could they be transferring data to that or some other iCloud related service? When I use my own personal iPhone 4S on the same network I don't get the problem! My iPhone is on my iCloud account which is different to the account that the other devices are using. That's the only thing I can think of at the moment. Anyone else have any ideas? If it is that then why are the devices transferring so much data?! Thanks in advance. It's driving me crazy!
