I tried to install the upgrade today. When I uninstalled the WLAN Card Utility, I lost my internet connection. That scared me so i quit and did a system restore. So are you saying that I will lose my wireless internet connection, but if I finish with the upgrade I will get it back?? I am not that knowledgeable about what to do if I don't get wireless capability again, so I would rather not do the upgrade than take the risk unless I know it will be OK after the upgrade.
Thanks for your help!
