Lost location tracking on my wifi iPad 64GB

This has been puzzling me for quite sometime now. My ipad "could not determine position" Don't know how it happened some of us advised it was due to some update. Tried all sorts of rest but can't get it. It was last working very fine in Jun 2011 and since then ( probably after an update) it kinked off. Any ideas as to how to restore and get the position. Have been using google maps and navionics software for position tracking and navigation.
Please advise ...thanks and regards


Yes I am using a Belkin 460 B , the same machine was working fine earlier and could easily determine position. Someone even suggested go to a place wher u could get satellite coverage. If am correct there is no inbuilt GPS receiver on iPad wifi models ( correct me if wrong). Any cracks to get the position.??????
