Samrt devices under 2.4Ghz

[aram3d]

I switch from a TM3200 to a wifi6 boost and now I amnot able to make ANY smart device to work. I tried turning off the 2networks 5Ghz (low and high). Also trying connecting to the ####Smarthome network and still any of my device can't connect to this router. 
I called many times to the technical supprt but they don't know how to help and thy just blame my devices. But those were working when I was able to split my networks in 2 myhomewifi-5ghz and myhomewifi-2.4ghz

Does any one have this issue and knows the work around?

The issue you're describing may stem from how some smart devices require a dedicated 2.4 GHz network to connect. With the Wi-Fi 6 Boost, network bands are combined under one SSID for better performance, which can cause compatibility issues for certain devices. Here are some suggestions to help resolve this:

• Many smart devices connect initially on a 2.4 GHz network. Disabling 5 GHz temporarily during setup can help. To do this:
  • Access your router's settings via the My TELUS app or web portal.
  • Temporarily disable the 5 GHz band, connect your devices, and then re-enable it.
    Check for Compatibility Mode: Some Wi-Fi 6 routers offer compatibility or legacy modes for devices that struggle to connect. Ensure this mode is enabled.
• Create a guest network and set it to use only the 2.4 GHz band. Connect your smart devices to this network.
• Double-check the device setup process. Many smart devices have troubleshooting guides specific to network issues.
