is this a pre-installed equipment? How do I connect to Wifi with this?

That looks like the Network Access Hub. That is just a hardwired router. Normally it's paired with a Boost Wifi 6, which is a separate white cylindrical device. If you don't have a Boost, you'll need to contact Telus. If you have a third party wireless access point, that could also be connected to one of the LAN ports on the hub.
