Thanks for coming back to me @Michael_burdiss.
I'm sorry that I have asked numerous questions, I do have two more questions, then we can log this with our support team.
Would you be able to use your mobile as hotspot and then try to connect via the mobile, to see if this works or not?
Also have you spoken to your companies IT department for them to check this, to see if there are any limitations on the ipad that would be causing this?
Regards,
