I got sick of poor performance with the RZ616 and swapped the card out for a Realtek RTL8822BE from an older HP
The performance has massively improved on my Framework 13 on both Win 11 24H2 and Fedora 41.
The performance issues on the Mediatek were so bad, I was getting as low as 14/15 Mbps down from the next room to the access point, and after swapping to the older Realtek chip speeds went back up to about 60 down in the same place
