(Wireless) LAN access working. WAN (remote) web access not working!

Calling all Linux wizards to sprinkle some magic and help!

The Problem:
================================================== ======================
I have LAN access but cannot access any remote (WAN) host (or
website).

Examples:
--------
What I CAN do:
a) Able to ping router on 192.168.2.1
b) Able to ping colleague's PC 192.168.2.2
c) Able to configure router using web interface on 192.168.2.1 fine.

What I CANNOT do:
http://www.google.co.uk (Error = "www.google.co.uk could not be found.
Please check the name and try again.")
================================================== ======================

Infrastructure
Channel 11
IP Forwarding ON
128 bit WEP (enabled) HEX

Failed attempts:
