Hi,
I have a client with the following setup.
Cisco Small Business Switch POE ESW-520-24P with a Wireless Access Point Cisco Aironet AP1141. Both the devices are upgraded to the latest firmware.
Connected to the ESW-520-24P is a Windows 2008 SBS 2011 with DCHP and Domain Controller. Along with the server I have a number of wired computers connected to the switch which do not have any issues and connect to the DHCP server without any problems.
When connecting two wireless devices to the AP1141, they get the IP address and DHCP from the server; but when connecting other devices apart the first two they will fail to connect to the DHCP server and do not get any IP Address. They manage to connect to the Wireless access point but they cannot contact the DHCP server.
I have double checked the configuration and took the AP1141 to my office. The AP worked like a charm with 10 devices. When I returned to the client, the issue occured again.
I have tried changing the port security settings on the ESQ-520-24P to 'unlock' but it didn't work.
A workaround to the issue was to connect the AP1141 directly to the router using a power adapter and skipping the switch.
I couldn't figure out why the switch is not working wit the AP1141 and don't know if there is the possiblity of incompatibility between the two devices. Any help would be appreciated.
Thanks.
