Xfinity XB3 Dual-band 802.11AC 1x1 capping my mbps to 433 on 802.11AC 2x2 (Wave 2) motherboard

So I have the Xfinity XB3 router, it’s specified as dual-band 802.11ac. I believe this to be a WiFi Wave1 device (also called a 1x1). It’s offering speeds over 700 Mbps. I’m looking at a 802.11AC wave 2 compatible motherboard (Gigabyte Z390 AORUS PRO WIFI ATX LGA1151 Motherboard) for a build. It claims to have 802.11AC 1x1 of 433Mbps, or 802.11AC 2x2 of 867Mbps. I know the 2x2 (also known as wave 2) wifi to be backwards compatible with my router’s 1x1 (wave 1) wifi; however, what I can’t seem to find anywhere I look is wether I will get the full 867Mbs using my router’s 1x1 wifi capability or if I’m only going to be getting the 433Mbps as a cap.

 

So if I use 802.11AC 2x2 (Wave2) WiFi connection via my Gigabyte Z390 AORUS PRO WIFI ATX LGA1151 Motherboard, will I get 867 or 433Mbps?

 

If I am capped at 433Mbps, I might as well use the MSI MPG Z390 GAMING EDGE AC motherboard, which has better features and is specified for Dual-band 802.11 AC 1x1 WiFi. Please just answer my question, don't sell me on getting one or the other or a different motherboard.

Well I'd imagine the connection speeds wouldn't change from what the router is capable and is doing now.

You will almost certainly be locked at 433 by your mobo. But honestly, even that speed seems overkill for a personal setup.

You will only get 433 Mbps.

You'll be limited by how much speed your paying for

didn't know where Wifi fell under so I posted it to where I thought it was relevant.

I actually did consider the posts where it wouldn't be relevant and thusly didn't post it there lol
