Q: iphone 4 personal hotspot keeps dropping off when connect to new iPad every 5-10 mins. I am located in Singapore, using Singtel.

Hi I bought new iPad late Sept of 2012.  I saw the demo at the shop on personal hotspot and speed seems fine even though the shop location was at B2 of the building. When I started using the next few days, it keeps dropping off every 5 - 10 mins ( or some times just couple of minutes ).   It does not matter even when I put the devices next to each other / on the move.

Any idea how to maintain the iPad and iPhone 4 personal hotspot ?
