Frustrating iPad WiFi situation

Frustrated here. I go to an office tower twice a week, and usually connect to a WiFi public network (in the veranda/conference rooms). No PW required. No "I agree ...). Phone, laptop, iPad connect automatically as you enter.

For a while though, nothing on the iPad. Haven't changed any settings. MBA and colleagues' iPads/iPhones all connect as usual. Only mine is problematic. Can see the signal in WiFi Settings, but just hangs and dismiss. And my iPad works everywhere else.

I have:
Reset iPad
Forget Network
Turn off (back on) Wifi Networking in Settings
Reset network settings

Probably can't go to the IT department of the building (or can I?), and explain to them only I has an issue.

I know they made some changes in private lounges on different floors a couple of weeks back - adding PWs. And since then, nothing WiFi working on my iPad only. Weird. Maybe something technical here that I can't understand.

Is the issue on my side? Remember, everywhere else, my iPad works perfectly. Any suggestions would be appreciated.

Thanks a ton.

First, thks for your reply s2mikey. Your '???????' and 'doesn't make any sense' is THE reason I'm totally frustrated. Think it makes sense to me??????? Everybody at that office blames my iPad. No way! Your reply confirms that i've done everything right to correct the situation. Last recourse, IT dpt. Then again, expect them to point finger at MY hardware ...
