Firstly, setting up the Reyee router (see Getting Started).
To connect 802.11bdevices, you may:
1. Update the SSID and password to the same as the original router's WiFi name and password, and disable dual-band integration, so that the old equipment (only 2.4G) will automatically connect to the 2.4G channel.
2. Enable Smart Home WiFi and connect your device to smart home ssid.
3. Or you may disable Wi-Fi 6 setting(Setting page >> Wi-Fi Settings), then reconnect the 802.11b device.
