I have 5 units of Lightweight AP1130 and they keep rebooting every 15 sec (seen from console). It query my DHCP server and straight away drop out and reboot. From my DHCP server, I could see DHCP request and release.
Since the AP is inline power, I could not disconnect the RJ45 and put in static IP. This happen to all the 5 units of AP.
Anyone have clue to troubleshoot? Last resort I may need to RMA all 5 units or open a tac. Thanks in advance.
Well, if your ap's are rebooting, it must be because the LAP's can't join the WLC. First make sure the time is the on the WLC and place the ap's on the same subnet and the WLC management and ap-manager's interface.... since you only have 5 LAP's. Make sure you have dhcp on that subnet also or you can set that up in the wlc if you want.
Spot the issue in WLC, the date/time is set back to 1980. Saw this message from message logs. Now the AP is up!
