Hello,
The section is still here but no matter what you do you can't get the wireless on. I had the issue 1 month ago on the previous power outage, yesterday I jumped straight to restore config when it rebooted without wifi again.
I have uploaded 2 troubleshoot files, I spent some time trying to figure out if it was a misconfiguration on my side. I have not generated a TS file with wifi off (we only have 1 computer with a rj45 connector, ethernet is use for the boat instruments, map sharing & rada ) but should be able to if it helps.
