If you’re not using the edge ISO, the wireless won’t work. Support is built into the kernel. The “regular” LM 20.2 ISO has a kernel that won’t work. It was built into the ISO at the time of the 20.2 release, so this won’t change. The kernel in the edge ISO will work until you update it, then it won’t. So while you’re updating it, install the 5.14.0-1007-oem kernel and pick that on boot.
I don’t think that will change when 20.3 is released in a few weeks, I’m guessing it’s using a 5.11 kernel and the latest versions of those won’t work. But by then there will be more advanced 5.15 or maybe 5.16 kernels to try out.
