iPod touch Safari could not open the page because the server stopped responding error.

first of all WTF.

Okay i just got the new 8gb ipod touch and im trying to connect to my wifi that ive had no problems connecting to with my psp and laptop, but everytime i try to go to google or use the internet i get "Safari could not open the page because the server stopped responding error." Its weird because just 20 minutes ago i was connected to my friends wifi at his house no prob but that was with a password. my wireless router does not have a password, does that affect it?

and the router is a linksys.

any help would be great.
Thank you.

edit: also as i said its brand new and i DID also format it. still nothing.
It does connect to it in settings > wifi but it wont get on the internet..

Thank you jessica. Yes i have connected it to my linksys router and Im getting 3 of those pie shape bars things your talking about.

Could a case affect the wifi?
