I have a Cisco 2106 Wireless Lan Controller at my main location. I am using AIR-AP1131 access points at two different locations. Everything has been fine for a few years. Now my wireless users at both remote locations are no longer picking up the ssid. When I look at the web interface I do not see any APs when I go to the Wireless tab. When I go to the WLANS tab I see the two profiles enabled that were created originally, enabled. I was getting "Controller is out of sync with the central timebase." I was able to set it correctly by Googling the error and following the steps but no change. I was hoping someone could help me troubleshoot this. This was set up by a third party that is no longer around.
