i did a search on google for "what version of linux uses theMediaTek 7902." The answer came back as:
The MediaTek Wi-Fi 6E MT7902 wireless network adapter is not natively supported by the Linux kernel. However, the driver for the MT7902 was added in the Linux 6.6.12 kernel series, and you can install these recent kernels to enable support. Ubuntu recommends using its mainline builds for this purpose.
OK I installed LinuxMint 22.3 here as a dual boot. My Windows works with the mediatek but I have no idea how to add the Linux 6.6.12 kernel series. Any simple answers for a newbie?
