If you have a working wireless connection you will have an IP address assigned by DHCP and a Default Gateway address - the IP address of the router.
If you haven't got a default gateway address, your firewall may be blocking access. Open the firewall to your LAN address range (e.g. 192.168.1.1 - 192.168.1.9) starting with the router's IP address.
