Hello TP-Link Community,

I’m experiencing an issue with my Archer AX20 router. I have configured a dedicated IoT SSID on the 5 GHz band, and everything works fine initially. However, after the router reboots (either manually or due to a power cycle), my IoT devices fail to reconnect automatically. I have to manually reconnect them or restart the devices.

Here’s what I’ve already tried:

Latest official firmware installed
Disabled Smart Connect
Security set to WPA2/WPA3 mixed
SSID is visible (not hidden)
No scheduled reboot enabled

Despite these steps, the problem persists. It seems like the 5 GHz IoT SSID doesn’t initialize properly after a reboot.

Questions:

Is this a known firmware issue for the Archer AX20?
Is there a beta firmware or upcoming update that addresses this?
Any recommended workaround to keep IoT devices connected reliably?
Thanks in advance for any help or suggestions!
