Router help!!

[wireless]

I’m trying my best to find out online how to use my netgear r6300 router as opposed to my t2200h. I just had 150/150 installed today, and I want to use my router. I ran tests and with the Telus one I get about 70/80, and with my router I got 170/180. The thing is, I cannot connect my Xbox to my routers wifi. All I want is to bypass the Telus modem, as I had it before I got the 150/150. I tried transparent bridging, but it says I’m an invalid user. Thank you in advance
