Many legacy IoT devices such as aircon, wash machine, door bell may encounter connection issue with new Wi-Fi standard AP.

To address intermittent connection issues with 2.4GHz IoT devices, you can try several steps:

1. Configure the 2.4GHz Radio Mode: Ensure the 2.4GHz radio mode is set to b/g/n. This can help with better compatibility and connectivity for IoT devices.
   
2. Ensure Strong Signal Range: Make sure the device is within a strong signal range to avoid poor signal issues that can cause disconnections.
   
3. Enable U-APSD on SSID: enable U-APSD to facilitate stable connections.
   
4. Use open or WPA1 security settings: since legacy devices may only supports older generation security method, dedicate an SSID set as open or WPA1 for these devices and set it to hidden to secure Wi-Fi.
   
5. Change WLAN Radio Profile Settings: Execute the following commands on the AP SSH console to disable ampdu and amsdu because legacy devices may not support it.
   
   Router# configure terminal
   Router# wlan-radio-profile default
   Router(config-wlan-radio default)# no ampdu
   Router(config-wlan-radio default)# no amsdu
