Question about adding a router to T3200 modem

[wireless]

The T3200 modem supplied by Telus is located in our garage meaning that in some areas of our house the WiFi signal is not great. We do however have Ethernet cables running from it to various rooms in the house. I was wondering if I could add something like...….

Plug it into and ethernet cable running from the T3200 to improve the signal in those rooms where it is weaker.
Would I run into any issues? Would any changes need to be made to the T3200 to accommodate it?

I appreciate any input that could be passed along.,
