(TLDR: if you want to use bleeding edge technology you must use bleeding edge drivers and firmware blobs)

We have tested WiFi-7 gear in our lab: from the cheapest TP Omada EAP783 to the latest most expensive Cisco AP+Controller.

Our findings:

- Driver quality from the modems is still below average on Linux. If you want to test Wifi-7 go with the Intel BE200 card - most stuff works there. Warning: this card does not work with AMD CPUs.

- We have seen quite a bit of problems from Qualcomm and Mediatek cards. Either latency issues, weirdo bugs on 6GHz (not showing all SSIDs) or throughput problems

- Always go with the latest kernel with the freshest firmware blobs

- MLO is difficult to get running properly. Very buggy from all sides. Also needs the latest version of wpa_supplicant - otherwise it will not come up. And be aware: there are several MLO modes and not all of them offer "two links for twice the bandwidth".

Also expect to hit problems from AP side. If you read the TP Omada firmware changelogs you see that they are still struggling with a lot of basic functionality. So keep them updated to the latest beta versions too.

I use a Qualcomm QCNCM865 in my privat setup with an AMD CPU. Feels like the latest firmware blobs and kernel drivers brought stability into their components.

what causes that? (I have no idea how wifi cards work)

What do you do that makes testing, the equipment, and labor worthwhile?

As I have been trying to tell the world and keep repeating. The best version and implementation of WiFI 6E is WiFi 7. So if anyone want decent WiFi 7 they will have to wait till WiFi 8.
