DNS problem? what's happening?Follow

Okay so I first goto my ID and put my password. When I try to connect I have conenction errors- sometimes when i retry, it reaches the update page. When i press the update button it has connection error again. Even though I reboot my ps2 it doesnt wanna work, I use broadband with cable cord to router. The lights seem to be on. All the cable lights are on. When I try browsing on certain sights, I have default pages- can't reach support pages, media like music sites, ffxi pictures. The only ones I can get to are warcry and this site.
Doing the cable modem d/c then wait minutes + turn it back on technique didn't work. I think its a virus but it doesnt seem to threaten the computer. I checked the security blocking sites- nothing there. Could it be my ISP? Or maybe I have to restore my computer? I get my network settings automatically on ps2.

the errors are like check your network settings mostly. I'm not an expert and sorta get cranky when it comes to this and don't mean to insult. Or could there be something wrong with my pol account since i havent updated it or logged in a while. its been a month and a half. please email me at :
