PS2 Online Help!

Well I have the ps2 mini with the built in online thing and it used to work online 2 months ago, but when I try to go online now, it doesnt work anymore! I have comcast cable internet and I was wondering if somebody could give me step to step help with connecting online please?

It's possible they've shut it down, though it's a bit early for them to have done that.

I still got my online its just when I try to do the test connection, it doesnt connect!
