Just wanted to share my experiences with Wi-Fi 7 on my Framework 13 and 16. Attached is a picture of a rebranded QCNCM865 card I bought on Ebay. I've tried this and one from MSI on both the Framework 13 AMD and Framework 16.
On Linux this chip works out-of-the-box if the distro uses a newer version of the kernel. It "worked" on Linux 6.12, but dropped connection often under usage. The card works perfectly fine with no issues on Linux 6.13. I've tested both Fedora and NixOS with the Wi-Fi card.
Windows doesn't support the card by default. I had to install Windows on a wired connection and install this MSI driver. The card works perfectly fine on Windows with no issues.
This card is an even better choice than the default Mediatek card for Wi-Fi 6E.
I remember trying to upgrade my WiFi card in my HP laptop years and years ago, only to find out there was a whitelist of components in the BIOS and the thing wouldn't even boot. Absolutely infuriating.
