Hi I just replace Deco M9 Plus to BE85 2 moth ago and my house very large I use upto 18 node and all of them connet with cat8.

Signal are very on all 6GHz and 5GHz, but the problem is my IoT cannot connect this new router, such as Ecovac Robot, Camera Wifi, Humidifier . All of them use only 2.4 Ghz, so it use IoT Network. I Try to connect, i sometime get fail to connect on my phone, sometime my phone connect to this signal, it alway get no internet, sometime get wrong password, even i put correct one.

Now IoT cannot use. Please fix it fast.
