I first got my HP about 6 months ago and have been browsing okay but not syncing wifi because I wrote my PC addr wrong. Because browsing I didn't look further but now working. WIFI sync is limited to Mail Contacts and Calendar so you may need to sync USB if use others like notes tasks filesync or favourites.
You must setup in ActiveSync to Allow wireless connection or Enable Remote Access depending on what version you have.
I found a great page that covers just about everthing from setting up your XP VPN server, Firewalls PPTP and setting up Virtual Private Network the connection PC
At one point it say configure your wifi router to allow PPTP connection. I have no Idea how to do on yours so you'll have ask del how to get onto your wifi router and setup? Your router will also need to be configered to use a certain range of addrs which is fed into incommign TCP properties. Example allows two addr in range but my Linksys used different addressing.
All IP addresses in example a his, his router addrs his computer addr which is 192.168.1.11 should not be taken litererally use yours.
