Hey all, I've been experiencing some annoying network problems, and I think my PS3 may be to blame as I have only started experiencing them after trying to add my PS3 to the network today. The problem I am having is that certain websites that I could access before now do not load, i.e in my internet browser on the PC I get the "could not connect to server" error and on the PS3 I see a "network failure" text screen. This seems to have happened after I tried to register to the Playstation Network through my PS3, as when I was submitting my details I got a "could not connect to server" error. When I went back onto my PC I noticed that certain websites were not loading, and after trying the PS3 browser the problem is also present there. I have ran the PS3 connection test which does not list any problems, I am really confused. My PS3 is on a wired connection, I have the PS3, Xbox 360 , My PC and a secondary PC connected through an ethernet switch to my BT Voyager 220v router. Can anyone help me out?
