You can supposedly convert your laptop into a Wifi hotspot by using software available on the following site. Works only with Windows 7 (it has advanced ad-hoc networking features built in):
Connectify
This is ideal if you have an internet connection in your laptop and want to share with other Wifi devices or can't use a router or even just do networking between two laptops.
I haven't tested this myself and would like to use this to share my bsnl evdo connection with other devices. If someone tries it out please post a brief review/reaction here.
