Constant Error: The CAPWAP connection with HiveManager was lost.

On a consistent basis, I am receiving, "The CAPWAP connection with HiveManager was lost." Units are coming up and down, almost on a cycle. Cabling is new, POE bricks look good. I can confirm that the units are going down and that devices are swapping to another AP and then coming back to the AP when it comes back up. Any ideas? I ca provide further information if needed...

Hello Luke,

Cases involving CAPWAP drops can be very involved.  In my next comment, I'll try to brush some broad strokes on this subject, but first, I want to recommend that you contact your service provider and open a Support case to get this issue properly addressed as this issue may require direct troubleshooting on your network.

In my experience, if CAPWAP is dropping,  it's usually caused by:

--- packet-loss / connectivity
--- big-latency
--- firewall
--- ACL

I did once work a case where HiveManager reported CAPWAP down when it was actually up.  You can see if this is the case by comparing the CAPWAP status in HiveManager > Monitor to the CAPWAP status shown in the APs CLI "show capwap client."  This issue was fixed over a year ago.

CAPWAP is a little bit like PING in that it maintains a keep alive to ensure the secure connection is up.  If PING drops, people generally assume that connectivity has dropped, and the same is generally true when CAPWAP drops.

I worked another case that lasted a long time.  The issue was resolved when the customer replaced a router which, apparently, was causing CAPWAP drops. 

In my experience, customer's have reported Sonicwall as blocking traffic intermittently in an unexpected manner.  It's not uncommon to see traffic marked as allowed in a config but being blocked in reality.

I recommend you inspect the underlying network as the most likely source of the CAPWAP drops.  If you feel CAPWAP is dropping for no good reason, please open a Support case and we can help you troubleshoot.

I'd like to add that we had this issue as well. We found that some of the switches were DHCP enabled and had duplicate IP's of some of the access points.
