installing wifi on b450m mortar
I own an MSI B450m Mortar board with a PCIe x1 open slot. I'm considering Intel's new Wifi 6 cards, like the AX200, but I'm unsure what's required to run them on my board. There seems to be confusion about compatibility—some say the AX200 works with Ryzen boards, which conflicts with the fact that it's designed for Intel X570 models.
It should function if drivers are available and the PCIe bandwidth can handle it. You might want to wait and check for a BIOS update. Additionally, some believe WiFi 6 remains slower compared to a wired link.
Looking to update that router too. Intending to overhaul my whole network setup.
I purchased a Gigabyte x570 Aorus pro motherboard with this Wi-Fi, but it’s not working well. I’m having trouble connecting to my network and the Wi-Fi report indicates the driver is likely the issue. I’m new to this and don’t know what to do, so maybe switching the router will fix it. Good luck!
I'll wait for this update. WiFi 6 is still emerging, and even the latest releases might not fully meet the standard. It's similar to how Draft N was released—vendors had their ideas, and not all the features we wanted were included. It's better to wait for the second generation AX gear, which has most of the issues fixed and more functionality added.
You've heard about Intel WiFi tied to the CNVi protocol, but the AX200 doesn't use it. The AX201 does. CNVi is a newer Intel standard (maybe based on PCIe?) that needs CPU support, and the MAC address is controlled by the processor, unlike regular PCIe cards. Regarding compatibility, I already have an AX200 for my laptop, but it's wise to wait for PCIe 2.0 M.2 adapters. With 5GHz WiFi or Wireless-AX, speeds will likely reach at least 2.4Gbps, while PCIe 1.1 caps at 2Gbps. For now, consider the Intel Wireless-AC 9260—it offers similar functionality to the AX200.
I've reviewed various tests and they align closely with your expectations regarding speeds. I plan to use a device with a swappable card and upgrade the chip later. At that point, I'll transfer the chip to another computer so a family member can enjoy wireless access on their desktop.
It seems there are no restrictions in place, all modern PCIe to M.2 adapters should work with up to PCIe 3.0 and possibly PCIe 4.0. Since there will be some extra load, a WiFi 6 connection at 2.4Gbit won’t reach those speeds in practice. Real-world performance won’t match the theoretical limits, so sticking with PCIe 1.1 shouldn’t cause problems. Most routers are designed to handle a 1Gig connection for LAN and 2.5Gig for internet, making it unlikely you’ll hit WiFi 6 limits on a single device. I saw a datasheet confirming the AX200 supports PCIe 2.1 Gen 2 already. While we can’t be sure it will fully work with WiFi 6, it’s unlikely to be as problematic as past incompatibilities where devices were completely out of sync with the specs. With so many laptops and boards selling WiFi 6 capable yet still using AX200 chips, I’m optimistic the SoC on the AX200 can handle at least Gen 1 features.
