We have 3 AP1130AG installed on our network with 2 VLANs. The APs are set up with two SSID, one for each VLAN. If two devices are connected to the same SSID on the same AP, they are UNABLE to ping/communicate with each other. If two wireless devices are on the same SSID and different APs, they are able to ping/communicate with each other. When the two devices are connected to the same AP/SSID, I can ping both devices from a server that is wired connected. I need to figure out why I can't ping/communicate between two devices that are connected to the same AP and are on the same SSID/VLAN. Below is the current configuration of the wireless AP.

This usually happends if the port protected was enabled:
(AP-if) bridge-group
But I can't see this configured.
can you try disable/remove the lines:
no bridge-group 1 source-learning?
bridge-group 1 block-unknown-source?
would that make any difference?

Thanks Amjad. I tried to make those changes but it told me I couldn't remove those commands. I then googles the error message I got when I tried to remove the commands. It brought me to another Cisco forum with someone that had the same problem. They corrected the issue by putting in "bridge-group 1 subscriber-loop-control."
I searched the internet for over 2 hours yesterday about this problem and couldn't find anything with the same issue. Here is the link to the forum that helped me resolved the issue.

Thanks for helping me get in the right direction.
