Dear Expert,

My organization have purchased Cisco 4400 Series Wireless LAN Controller and  9 unit of Cisco Aironet 1240 AG Series on year 2008. There is no major problem since we're start using this product until last week. We're now facing problem whereby any computer that connected to this wireless device cannot browse to the internet.

We can ping to any web server and also telnet/ssh to the server, but cannot open any website through Internet Browser. We also can ping using URL eg. www.google.com which means the DNS is working fine but still cannot browse it. We don't think it is Firewall problem because
we also cannot browse to our Internal Website which don't have a firewall between them.

Please help us to solve this problem.
