Hi,
I am trying to use my AP with my cable modem. I have upgraded to the proper ios but am still running to a issue. Ideally, I want the AP connected to the cable modem and client would connect to the AP, get an IP and be able to surf the web. Right now, the ap is the only device that gets an IP from the modem (Moto sb5120). How can I enable: (1) the AP to act as a dhcp server and (2) forward web traffic to the modem?
Here is the conf. from the AP. I erased the changes I made during testing. Any help will be appreciated.

Hiya! All Cisco Access Points are bridges, meaning that they simply pass IP traffic from one interface to the other without intervening. It sounds like you're looking for the functionality of a router (to do address translation & DHCP services). These are not part of a 'bridging only' solution.

Hi,
Thats what I figured so i put a linksys wired router between the AP and the modem. Now, when i have one wireless client and one or more wired client in the linksys, i cant get on the web.
Destination unreachable.

The AP is a bridge, which means you have to setup DHCP server on the Linksys. Most Cable service providers only allow one IP address to be assigned behind the modem, so thats why. Check the number of DHCP clients you can assign on the linksys.

Hi,
I got it to a point where it works. But, when I connect the laptop to the wifi, the connection drops after a couple of minutes. I have tried multiple laptops.
The only way to get it back is to power cycle the cable modem and the AP.
