Say you have four Cisco 1142N's... and they're known as AP1, AP2, AP3, AP4. They all share the same SSID/encryption settings.
Clients can connect to any of the four and associate just fine, if you move physically so that the client device picks up another AP, that works fine also...
So, going from AP1 -> AP2 - no issue.
However, if you go from AP1 -> AP2 -> AP3 ... you start to experience issues, as described below:
- Client can ping the AP it's connected to, and the switch (all on same subnet), at all times.
- AP that the device is connected to can always ping the client
Client cannot ping, or access, anything besides the AP and the switch once you jump to the third AP.
All access points share the same configuration aside from wireless channel/hostname/ip.
- Running 12.4(25d)JA2 firmware
- All access points on the same subnet, no VLAN's
- Clients can initially connect fine to any of the four AP's and work without issue.
- Client can roam to a different AP ,and then come back to the original and everything starts working again.
- Switch is a Cisco SG500

Is there something that I'm missing or not thinking of that would cause an issue in a setup with multiple AP's? I've searched on Serverfault and Google, read the Cisco docs, but I've been unable to find any type of solution.
I found one discussion that described a similar situation, but no solution: https://supportforums.cisco.com/thread/2182134
