I have managed to get WiFi tethering working on the vortex in infrastructure mode
First off you need to be rooted for this to work obviously
second off download WiFi tether from
android-wifi-tether - Wireless Tether for Root Users - Google Project Hosting
and click Get it from Here
Third go to settings and make sure that Device profile is set to Auto than go to Setup Method and change that to Netd and that should do it. Now any wireless devices can connect to your phone!
