Hello,
So I got the 6G network working on the Linksys MX8500.
I followed this guide here:
https://www.reddit.com/r/homelab/comments/ymecyp/wifi_6e_softap_qcn9074_on_x86/
The key is basically to create a new board-2.bin using the 0x2A (162) board-id number and assigning it to the 255 board-id.
As per the guide, the 162 is the 6G board and the 255 is the generic one when the chip has not been fused into any specific band.
It should also be possible to run it at 5G but when trying that, I couldn't get it to work.
I did some simple test and the connection is working (from android phone to AP on the 6G band).
Thanks,
