Smart Steering can NOT be turned off - Arcadyan Boost 2.0

I recently got Telus and they installed a Technicolor FXA5000 network access hub and Arcadyan Boost 2.0 Wifi modems.

The modems do NOT have the functionality to disable 'smart steering' OR enable 2.4Ghz Wifi. (That was tried on the admin portal Login)

What that means is that customers cannot use most 'smart' devices as they require 2.4Ghz to be set up.

**************
Can TELUS please:
1. update the firmware/software of the Arcadyan Boost 2.0 to allow detection of 2.4Ghz band by 'smart' devices even if just temporarily for set up
2. OR ability to disable of smart steering

OR does someone know of an alternative method to connect my smart devices ?!

Thanks!
