WiFi Stopped - LM 20.3 Cinnamon

[gentisle]

Wifi and Bluetooth Not Working After Shutdown
I have an Asus ROG GL752VW with Linuxmint 20.3 Cinnamon. Everything has been fine since installing last year. All updates applied including kernels. Speaking of which, I just installed 5.15.0.72 a few days ago. It's an Intel 7265NGW, so the iwlwifi driver. Ethernet works fine.

This is NOT a dual boot machine; LM 20.3 only, though I've been thinking of adding another Linux distro.
Never used secure boot; so off.

I have an Asus ROG GL752VW with Linuxmint 20.3 Cinnamon. Everything has been fine since installing last year. All updates applied including kernels. Speaking of which, I just installed 5.15.0.72 a few days ago. It's an Intel 7265NGW, so the iwlwifi driver. Ethernet works fine.

Had been using the computer for a while the other day. Decided to connect via RJ-45 for some reason, and if my memory is working well, I also used the wifi simultaneouly. Shutdown at the end of the day, and as soon as I booted up this AM, no wifi, and Bluetooth will not connect automatically when i turn on my headset (previously it did).
So a few days ago when everything was fine, I updated the kernel, and I was using Ethernet for my connection. Those are the only things I remember doing differently. However, I tried reverting the kernel through the update manager to the previous one, but still no wifi.

Things I've tried, and the results

when using inxi.
When putting the computer into airplane mode via Function + F2, the Bluetooth icon will put a red circle w/white 'x' on the BT icon in the taskbar. So I have not disabled the wifi via keyboard.

Also, I wondered if the hardware was OK, so I booted my trusty SystemRescueCD USB stick, and yes, the wifi works fine. So something went awry in my Linuxmint config.

I looked at the power save:

It had been 3, but I changed to 2, but still no wifi.

What am I missing? Thanks.

The only answer I can come up with after all the Googling that I've done is to backup, wipe the HDD reinstall, and restore.

I would reset BIOS to defaults before a reinstall, maybe even power off, remove power cord/battery and hold power button for 20 seconds. Reconnect everything and boot
