Unable to check for updates ipad mini 2
Hi
I am unable to check for updates for my ipad mini 2. When I tried to connect it to my computer to update it through itunes it says that it could not connect to this computer and unknown error has occurred. I have tried a hard reset on the ipad twice no luck. I dont know what else to do? Any ideas? I cant update anything on in itunes and my son uses it for school.
Thanks
iPad Mini, iOS 9.2.1
