Guys, any of you try connecting your Wildfire with Ad-Hoc wireless connection thru a internet-connected PC (hot-spot)?

I've tested the whole morning, it's unsuccessful. Because Android can't connect on adhoc basis.

Is there any better solution? FYI, my office does not allow Wireless router due to Fix IP issued for each person. Only way is to connect thru my notebook's internet. Well, you may ask me, why need internet on Wildfire, since already on notebook...because - Pingchat & Whatsapp social app in my Wildfire, can't connect from notebook.

Please kindly advise any better solution. Using 3G or HSDPA is draining my battery very much. Tested, at home last Sat, whole day connected to WiFi, it's more battery saving compare to connect to 3G.
