Sometimes, we get emails stating that access points have not been properly discovered in WiFi Manager. They seem to land up in the “Unknown” category.
Most often SNMP may not be enabled on the device. What’s the solution? Login to the web interface of the device and enable SNMP. Unfortunately, you will have to do it for each device on your network.
Even if the SNMP is enabled on the devices, improper SNMP credentials will not allow WiFi Manager to discover them correctly. The SNMP credentials are not same as the device-web-interface password (unless you have put it that way!).
But once that is done, you can use WiFi Manager for just about anything!
