Yesterday i finally decided that I'd had enough of my ageing iPad2, and bought myself a shiny new iPad Air 2. I made sure my iCloud backup was up to date on my old iPad, and powered on the new one and started the, what turned out to be, VERY long update process. The restore didn't take very long at all.......which was a bit of a concern, especially when i got a message saying some items could not be restored. Then the apps started to restore, and it's now taken over 10, yes 10 hours to get back all my apps. I had to resort to deleting a few and redownloading them as they seemed to get in a "restore loop". Well its finally all done, but I think I've discovered what might have been causing all my problems. I had forgotten that previously due to a DHCP problem on my router, I had given my iPad 2 a fixed IP address. So obviously the restore to my new iPad gave it the same IP address. I only realised this after all the kerfuffle, and it's now been changed. Now I'm not that technically competent, so this is only an assumption, and perhaps someone who knows better than me can comment. I know the IP addresses were the same, but the MAC addresses were still different, but could this have caused the problems I encountered?
