Samsung Galaxy Ace portable hotspot error

My wife has been using Samsung Galaxy Ace for a year now. But several
months back she always got an error when switch on portable hotspot
feature. Nothing that I did would resolve it. The original firmware
was 2.2.1.

A week ago I updated the firmware to 2.3.5 and the portable hotspot is
working fine now.

I think the problem lies in the old firmware. Nevertheless I can not
justify what went wrong. Still, it is good to have this feature back.
