Too many possibilities to tell.

Is your DNS server configured? It should be in /etc/resolv.conf.

Is your default route set?
netstat -rnf inet

What is the output of
ifconfig wlan0

Most of these things should be set by DHCP, but may not be.
If it shows as associated, try pinging your router.

Still, without more information, it's all just guesses on my part.
