T3200M Transparent Bridge Mode

[yyc2]

Hi there,

I know there's been lots of questions about using you own 3rd party router. However, I want to turn my T3200M purely into a modem and want to enable Transparent Bridge Mode. When I try to select it and apply changes it says "invalid user". 

Is there a way to set this, or does a Telus technician need to come in, log in and enable this?

Thanks
