As the original poster noted, this seems to be an interaction between the specific access point or router and the AMD RZ616 driver, and not something that other users are seeing on their home networks.

The RZ616 is AMD's rebrand of MediaTek MT7921K. Mediatek does have a dedicated team working on Linux drivers, but we haven't seen their or AMD's plans: https://wireless.wiki.kernel.org/en/users/drivers/mediatek

All of that said, 13th Gen Intel Core and specifically Intel AX210 WiFi are quite mature in Linux, and Ryzen 7040 U-series and RZ616 are quite new. All indications and communication we've had with AMD point to them having a strong desire to deliver a great Linux experience.

I bought MT7921K on a PCIe card for two older PCs and they work fine, AX210 is better but Mediatek is not bad - between two of them on 6GHz they managed >1Gbps and didn't lock up at all even after 200GB.

Just had to use at least Linux 6.1 or newer and had to set regulator domain manually... Compiling upstream mt76 enabled even more stability and also enabled AP+STA operation.

Do Intel or AMD forbid you from mixing and matching wifi cards ? Why the unnecessary fragmentation ?

[nrp]

There is no specific commercial restriction preventing us from mixing and matching, but there is also no commercial/technical support from either party around the mixed solution. That means that if any issues come up, we have no path to resolving them, including crucially if we ran into issues during RF certifications.

iirc Intel has a line of cards that only work on their CPU lines and otherwise, Intel seems to have soft blocked their compatible cards from OEMs - we can't get AMD laptops with Intel nics anymore where I work from all vendors.

Otherwise nope - I run Intel ax cards in all of my laptops (HP, Lenovo, Acer, Asus, surface laptop 4 -- came with Intel) and they are solid in windows and Linux.

> Intel has a line of cards that only work on their CPU lines

Intel sells CNVi versions of their WiFi module lineups that only work on chipsets that support it.

You are probably in a better place than me to really push them on Linux support.

Mediatek's Linux support seems reasonable, but I've only had experience running the AP cards in OpenWRT, not the little baby client cards.

FWIW I use my MT7921K as an access point. It can only do one frequency at a time (2.4/5/6GHz), and I haven't tested the 6GHz capabilities, but I've not had much trouble with it so far.

i've got the Intel AX210 WiFi/BT (bundled with asrock b650e pg-itx). as for WiFi it worked out of box, but the drivers for BT are horrible, some of my devices aren't recognized (while bt-usb dongle works fine), and there are plenty of other issues like disconnecting or buffering keystrokes from keyboard.. so i've had to disable the Intel AX210 combo in bios, to keep my system stable. for the WiFi part it's ok, otherwise i'd recommend to wait for better BT support on linux.

So my Framework laptop is currently in transit. In theory, I would just swap the AMD wifi card with an 25 euro Intel AX210?

Try the card first but yes, you can do that.

[felixg3]

You can also replace the MediaTek RZ616 with a Qualcomm FastConnect 6900 card, which is equally supported by AMD and default on their Ryzen Pro models. I’m very happy with mine, got it from eBay.

Yep this should be possible AIUI funnily enough, it is not possible on the Intel models.
