AP Registered SM's

I have a strange issue. We have several AP’s 5.7, 2.4, 900, you name it. on a few I have been experiecing weird issues. On 3 Different APs at 3 different locations will drop every user on the ap and I will have to reboot the AP for it to come back up.

We just purchased this network and there is NO SYNC on any AP or BH. On my current network I have sync and do not experience and have not expereinced any of these issues, could it be a SYNC issue?

I feel that it is, but want a second opinion.

Are you using a CMM? Sounds like you are on the right path in thinking it may be a sync issue. If the AP looses sync then the SM’s would drop off.
