Question : How to switch from peer-to-peer adhoc wireless back to wireless network

I need to be able to easily switch between an adhock wireless network and a standard wireless network on XP pro without having to change the ip configuration and network settings each time.  Can someone recommend an application that works well for this?  

Thanks,

I've used this in some enterprise environments to manage wireless profiles, works well, although I've never tried to use it with adhoc peer-to-peer, but it might have features for that:
