iPhone Wi-Fi Connected but not connected to internet

So i just received my 2g iphone with 2.2.1 jailbroken and unlocked..
When connecting to my home network (Actiontec router, qwest internet) it connects with no problem and i get the wi-fi logo in the top left..

but when i attempt to open safari or cydia it tells me that there is no internet connection?

looking around on google i think that i understand that it's a problem with the iphone resolving the dns.. is this actually what it is? and how do i fix this problem?

any advice is GREATLY appreciated i've been trying to figure this out for hours

anyone? would it help if i included ip information?
DHCP automatically assigns the ip and subnet mask..
where do i get the proper information
