different BD-P3600 wireless connection problem

I've been reading this forum for the past week, and I don't see my problem mentioned. I get a wireless connection to the internet via the BD-P3600, and the updated software has been installed. My issue is getting ANY of the services to connect - BBuster, NFlix, Pan and YouTube. In NetFlix I get an error Proxy Connection Failed. The other services just say they can't connect. I checked all my network settings and they seem correct- not sure why I can connect but these services can't. And I just created a shorter network password just in case.
computer OS: Vista, Router: Linksys WRT320N, Security setting: WPA Personal, Internet connection: Cable, Port: 0880 (opened on router)
When I read about other people having success connecting to the online services, there must be something very obvious that I have missed. I have no idea what that could be, I truly hope that's the case.
Thanks
