I'm having issues trying to setup an Aironet 1131AG with DSL internet service. I have the Aironet 1131AG connected to a Cisco 3560 8-port POE switch, but can't get internet connection when connected wirelessly. I enabled DHCP on the Aironet and get assigned an IP, but that's as far as it gets. I can get internet connection if I plug directly into the switch and I can ping external addresses from the command prompt of the Aironet 1131AG, but no service when connecting a device wirelessly. Devices connect successfully to the Aironet, but nothing else.
I was wondering if someone could point me in the right direction on setting this up? Also, can I get by with dhcp on the aironet or do I need a router? The switch and aironet have static IPs in the same subnet. I need the simplest way to get internet connection, since it will be for guest.
Here's my current configs:

Not sure if the 3560 image you're working with has it, but try enabling the DHCP service on the 3560. "Service DHCP" I think. Don't have one handy so can't give you the syntax. Also, is the DHCP server on a different VLAN than your clients? If so, you'll need a DHCP helper configured on the L3 VLAN interface that the clients are on, pointing to your DHCP server's IP address.
Take a look at the link below. This configuration is in the 1131AG section and should help you set up the AP and the switch. I personally like to have the DHCP server on the switch rather than the AP to centralize assignment of IP and troubleshooting.
To set up the DHCP server on the 3560, use the following commands:
ip dhcp pool data-pool
network xx.xx.xx.0 255.255.255.0
If you like to exclude IP addresses from the pool use:
ip dhcp excluded-address 10.1.1.200 10.1.1.254 (example)
Removing the DHCP server from the AP and configuring the service on the switch should help you isolate the issue further. If the wireless clients obtains an IP address from the switch, then the clients should be able to reach the internet.
1. Is the DSL modem acting as a router? If so, is the DHCP enabled on it? Disable it and let the switch be the DHCP server.
