iPAD3 connect BlackBerry9900 hotspot ??

[kkcci88888]

Hi, I have upgraded a BlackBerry 9900 to 7.1.x version and it can now can act as a hotspot. the iPhone5 / iPhone4 can easily connect to it via wifi without any issue. However, I tried two iPAD3 but found very difficult to connect (all failed finally). However, another iPAD 1 can connect without any problem..

Any idea of this ??

Thanks
