The Arcadyan hub is the new router/modem Telus provides, usually to people that have Gigabit+ internet. The T3200 Advanced Wifi Modem is the older model, more commonly used with slower speed internet or with non-fibre setups. I think the Arcadyan can only be installed if you have Telus Fibre.
When you ask "is it not installed properly" what issue are you having?
