Gamer Problems - IPs, Ports & Call of Duty

[news]

Hey folks!

I recently switched from Rogers/Shaw to Telus to get Fibre, I have the 1.5Gig plan and a brand new installed setup for Fiber. I don't know what they are called but, the one smaller square and one large main square installed on the wall, plus the tall monolith looking thing for Wifi.
(Can you tell I have no idea about this? I've never had a problem before the switch.)
Anyways - both myself and my boyfriend who live here are live-streamers who game, and we are now having problems when both trying to game at the same time, specifically while playing Call of Duty Modern Warfare 3.
The internet tells me it's because we are on the same connection/IP - and suggests making sure specific ports are open, setting static IPs, and a bunch of other things but.... I keep being told I can't do that with telus, and need to purchase an aftermarket Router?
It doesn't seem to matter if I am on Xbox and he is on PC, or also Xbox - one of us cannot log into the game, or if we do manage to log into the servers we cannot find any matches.

Does anyone have any suggestions here?
