try to pull ip's.
Click start
Click Run
Then type cmd
Click ok
then a new window will appear
in that window type this "ipconfig /release"
this should flush your ip
now once that is done type this "ipconfig /renew"
it may take awhile but it should give you a new IP
if it doesn't then you have a connection wrong on the router.

Also try this
Click Start
Click Settings then/or find the Control Panel
Click network connections
Click Network Setup Wizard
You should be able to get it form there if you still have problems PM me with more details
