@d0ugmac1 OC-300 controller version 5.12.9 firmware 1.19.3 build 20230906 Rel.38429, I have installed a PFSense, in the Pfsense a network segment was configured for the Wifi and that is the one that goes against the controller, this is the configuration, I attach the diagram, in this case the WiFi is a Vlan that passes through the HP switches and does not have communication with the other VLANs configured in the core.

Many thanks

  @d0ugmac1 Now we have 1151 clients distributed in 5 SSID via Mac Filtering, all the ap and the controller OC-300 are conected to switch port in the same vlan, The PFSense gives the IP addresses to the APs and the OC-300 have a static IP.

We have an ER7206 VPN router; but I have not been able to figure out how to integrate it into the scheme and make it work, it should be from the PFsense to the router and from there to the controller, I suppose if it is possible that would be ideal.

Thanks

  @d0ugmac1 I really thank you very much for your support, I tell you, all the SSIDs are in the same VLAN and in the same network segment, I will make the change you suggested in the AP for the tests and I will tell you.

Many thanks

  @d0ugmac1, Thank you very much, We made the changes to place a fixed IP address on each app as you suggested and it really substantially improved the connection of the devices.

It only remains to solve one point:

* Some APs remain in an adoption loop by the controller, that is, they are disconnected, the controller run the adoption process until they are connected again.
