1 What exactly is the instability issue?

 

2 Will the EAP670 disconnect from the controller frequently?

 

3 What is the present status of the change?

 

4 Will the wireless clients repeatedly fail to connect to the EAP670?

 

5 Do you just forget the EAP670 and the problem goes away?

 

6 It does not have the compatibility issue with the controller version 5.14.26.1. The controller's up-to-date firmware is not available on the website; I will notify the relevant department.

1 Please see the links in my first post in this thread

2 The EAP670 drops out completely, disconnecting from the (SDN) controller, and also stops serving WiFi.  Curiously, according to the lights on the switch (TrendNet PoE 2.5gb non-managed) it is still physically connected, drawing PoE, and there is traffic on the link.  I.e. there is a layer-2 connection, but nothing at layer-3 (web UI, ssh). 

If left alone it will eventually come back up, after about 1/2 hour.  If power-cycled it comes back up in 3-4 minutes.

3 I've been running without the SDN controller for a week and the device itself, unmanaged, has been completely stable.

4 As in (2), the EAP670 "crashes" and stops providing WiFi. 

5 I completely removed the SDN controller software, factory reset the EAP670, and configured it using the device's onboard web UI. In that state it has been stable for a week.  I am now going to reinstall the SDN controller and adopt the device to see if I can recreate the instability.

6 I'm using the SDN controller on Windows 11, not a controller hardware device.
