Xfinity XB3 Dual-band 802.11AC 1x1 limits speed to 433 Mbps on 802.11AC 2x2 (Wave 2) board
You have an Xfinity XB3 router with dual-band 802.11ac support. You're considering pairing it with a Gigabyte Z390 AORUS PRO WIFI ATX LGA1151 board for a build. The motherboard claims 802.11AC 2x2 (867Mbps) and 802.11AC 1x1 (433Mbps). Since your router is a Wave1 device, it should work with the 1x1 Wi-Fi, but you're unsure if you'll get the full 867Mbps or just 433Mbps. If you stick with the 2x2 option, you might achieve the higher speed, but you may be limited to 433Mbps. Alternatively, switching to a motherboard like the MSI MPG Z390 GAMING EDGE AC could give you better performance and full 867Mbps potential. Just decide based on your needs.
You're likely to be blocked at port 433, and that performance might be more than needed for a home configuration.
I wasn't sure about the Wi-Fi issue, so I shared it with a place that seemed related.
I also thought about the updates that wouldn't apply, so I didn't include them here lol
