what is error code is ox80090318

I cannot connect to the ITunes store on my computer and keep getting this error code. I tried to sync my I pad and it starts and freezes up at 2 0f 8 and then won't let me into the iTunes store I have reloaded and repaired the iTunes no luck have no idea what the issue is. Is there a way to tell if it even recognizes my I pad air. I just started having this problem this past week. Prior to that it worked fine

I t has my music and purchases on it and hopefully did not revert back to my old Ipad.
