@Joseph-TP No, I can't modify the 2.4G channel when I log in to the WEB management interface. It's grayed out and I can't control it. I have tried restoring the factory settings, but there is still...

2.4G cannot be found. Restoring factory Settings still doesn't solve the problem. The 2.4G channel cannot be changed in the app. Currently, 2.4G cannot be used
