Wifi failed to connect after recent upgrade

I had the same problem (no wifi) when I upgraded the Linux kernel to 6.2.5. I used Timeshift to go back to a prior version of the kernel (6.2.1) and then when I upgraded (using yay in a Terminal) the update took me to 6.2.2 and wifi is still working.
There is this post warning about the 6.2.5 kernel:
