There is an internet connection that always used to work when i went on my psp's internet browser. However, today for some reason while it was connecting to my homepage (when i opened the browser) i waited for a long time and a window popped up and said DNS error occured (80410410). What does this mean?? what is wrong?? how do i fix this? I got this error while i was in bulgaria over the summer but never in canada.

ps: the connection strenght is usually around 70%
