Upgrade to Paralles 3.0 - Internet not working

Hi, I finally payed the money to ugrade to paralles 3.0 although I found out when you upgrade from a trial version you could get it cheaper. I bought 2.5 or so end of march.
Now after upgrading to paralles 3.0, which worked somehow fine, I started Firefox in my XP Professional. It is not connecting anymore to the internet! That is frustrating! Firefox is the only application i installed so far in my XP system besides the anitivirus software.

I am connection via WLAN to my DSL router. What have i done wrong or what do i need to change to get it running again? Is WLAn not suported anymore with paralles 3?

I have a MacBookPro from march 2007

 

oops, now i found out what the problem was. After the upgrade, the network adapter was switchet to the Gigabit-LAN. I changed to Bridged Ethernet and now it works again.
