System: Windows 11 Home 64-Bit 10.0.22000
Battery or AC: Both
Model: ASUS TUF Gaming F17 (FX706LI.310)
Reset OS: Yes
Frequency of occurrence: Ongoing, Consistant
Screenshot or video: Yes. Your system won't let me post them...
========================
Detailed description：
On one hand, I'm thankful to not be alone here. On the other hand... I know that means some of you are in the same painful situation...
The WiFi option occasionally vanishes from the quick menu at the right, and no, it's not hidden away... It's gone.
As soon as the computer tried to do anything, it would freeze and BSOD with the same error. I didn't need to browse crash logs to guess that the BSOD was from the MediaTek driver. I read online that it could've also been a ssd thing, but that doesn't seem to be the case since both internal and external drives work fine.
So what have I done?
Reset the OS - It booted back up without a wifi option, but it hasn't crashed since.
MyASUS - Completely useless. "Something's being done about the WiFi"? No secret update to install, nothing changes.
Update Driver - Would be nice if it was listed to begin with.
Install/Reinstall Driver - The Driver listed on the ASUS website for my model is the Intel LAN Driver. Didn't work, but it wasn't really going to, was it? Got redirected to the Lenovo website on one occasion. That didn't work either.
Hold Power Button for 60 seconds - I was skeptical, but I recall having done something similar when my Bluetooth adapter had a similar hissy fit. Only worked as a temporarily solution since the WiFi option was gone within a few minutes.
Professionally Serviced / Get a new Laptop - I really don't have the money for that right now and the computer is totally fine besides the missing WiFi error.
[Technically...] I can still use the internet on this laptop because my WiFi extender has an Ethernet option. I don't intend for it to be the permanent solution since a missing WiFi adapter might cause another flurry of BSOD soon. If there is such a legendary driver version or a magical patch that'll fix everything, please get it public ASAP.

The wireless adapter is indeed gone again.

Falcon_ASUSDecent Idea, Didn't Work. WiFi option still missing from the task bar and the BSODs have started reoccuring. Going to power it down and try again, but if this is anything like the last time, the WiFi uninstall it's own driver before I can update it.https://zentalk.asus.com/en/discussion/comment/217291#Comment_217291

So, the driver update didn't install because the version that I have currently installed is V3.00.01.1336.
Still didn't work. I could remove all the drivers and attempt reinstalling 1244.

More interesting news. Uninstalled 1336 since that version potentially might've been a rogue driver. Driver immediately reinstalled itself with a different version number.
V3.3.0.541
Updating the Driver again did nothing.

You want to know what V3.00.01.1244 did when i finally got it installed?
It worked for a solid two minutes, then bricked my laptop into another BSOD.
When the laptop rebooted, the driver had promptly removed itself and the adapter remains missing.
...
Either you have the answer or you don't. Stop sending me bugged drivers, and no, I'm not paying an arm and a limb for service. Last time I did that, I got back a wiped harddrive and a 'Sorry' with no refund.
