I used Virtualdavids install and files and at first it worked flawless for most of the day, connecting and disconnecting when I was away. Then at the end of the day I was using it and the connection died and would not come back on. I"ve been battling with it using different configurations and nothing would work until a few minutes ago I realized my problem.

I had not set up the Ad-Hoc on my Laptop (Vista Ultimate) but it was connecting fine when it would show up in the list of networks. I would double click and it would connect no problem. Then when it stopped working I tried to setup an Ad-Hoc on my laptop and it worked a few times and stopped working. Then just now I changed my Ad-Hoc network name on my Laptop to a different name than the one on my phone and it is working perfect so far.

Don't know if it will help anyone out there but thats what happened with me.

Also I was not able to connect to other networks at first until I went to Settings/Connection/Wifi and changed the selection from Computer to Computer only to all available. Then my networks came up and I was able to connect.
