I'm having the same problem with connecting to PSN, internet is fine but won't log into Playstation network. I usually am on there a lot but have been hooked on a computer game lately so I haven't tried to play in several weeks, so I'm leaning towards a PSN issue somehow. My setup hasn't changed much, although I did have some recent posts about reconfiguring locations of things, I get a solid signal that I should be able to logon ok. I'll keep experimenting and let you know if I find anything.
