just a tip for u all into this kinda tech
always connect ure wireless projector to a nearby AP...so that when
u connect to it...u can surf as well as project at the same time
compared to if u use it via peer 2 peer connection
dun use 3rd party wireless connection software(like thinkvantage
access connections) as there will be more often than not....a
conflict and no projection of ure PC/Laptop would occur...use the
built in windows wireless connection apps...
and please switch off the firewall...
or atleast unblock it when the wireless manager is running
