Network card not detected, unable to connect Solved/Closed

Question

Hello,  this afternoon I realized that my computer can no longer connect to the internet. Indeed, in the network settings, only airplane mode remains. It appeared all of a sudden, and I can't see what I might have done to turn everything off.  I have tried many things, installing the graphics card driver, manipulations I found here and there, but nothing works; it stays the same and I don’t understand what I did wrong. I am attaching the details of the network settings where it clearly shows that the PC no longer detects anything. The model is an ASUS ROG Zephyrus G14 which I just bought a month ago, that's why I find it strange.

Hello,  After some research on English-speaking forums, I noticed that many people had the same problem with the same wifi card. One contributor recommended pressing the off/on button for 60 seconds (while on battery) and then turning it back on. Several forum members responded that this had worked for them. So I tried it, and miracle of miracles, my wifi connection reappeared...

Hello So your TITLE is incorrect because your card is indeed detected: MediaTek Wi-Fi 6 MT7921 Wireless LAN Card...  Have you used a keyboard shortcut that might have disabled the Wi-Fi?!?  Your Asus Rog features an airplane icon on the F12 key... It's the Airplane mode that disconnects the Wi-Fi. So please try, calmly, without insisting, just wait a bit...  Fn+F12 for example  Cheers If my response helped you, a little thank you would be super nice... Is it resolved? The green button at the top is good!  Let he who has never opened a user manual throw the first mouse ;-)

Good evening, thank you for the reply.  I’ve already tested FN+F12 and it doesn’t change anything; it activates and deactivates airplane mode but it doesn't make a difference.

Hello Yet you do have your Wifi card! You say you tested Fn+F12 without any change...  Do you have the network icon at the bottom right in the notification area? Does nothing appear when you click on it? Press Fn+F12 just once and test again... Nothing?  If you have a smartphone, enable Wifi sharing (this is just for testing) and redo the above steps with the smartphone near the Asus...  If nothing reacts, try: Windows key+X, opening the "Device Manager" and after clicking on "Network Adapters", deleting the MediaTek Wi-Fi MT792 card, then restart the machine...  Test again, calmly.  Cheers If the response helped you, a little thank you is really nice... Is it resolved? The green button at the top is good!  Let he who has never opened a user manual throw the first mouse ;-)

Hello and Happy New Year,  Have you tried to solve the problem,  hover over the network icon, right-click, and choose troubleshoot.  If you don't know how, it's best to do it manually in the command prompt as an administrator  To open the command prompt as an administrator, you need to type the word cmd  in the search box next to the start menu button  this post is not finished, I will provide the continuation as soon as possible.

Hello, I have the same problem since yesterday, it's starting to drive me crazy, I've been looking for a solution for 3 hours! ???? help please

Thank you very much!  As someone who owns a Zephyrus G14 myself, I can confirm that it has nothing to do with airplane mode, but it's indeed a hardware bug of the Wi-Fi card. I regularly encounter this problem. I've even sent it for repairs for the same reason.  I'm very happy to see a simple and quick solution that works perfectly. I'm going to note it because yes, disabling and enabling the card doesn't work. Moreover, all menus related to Wi-Fi disappear. Even the Asus BIOS diagnostics show that there is no Wi-Fi card in case of error.  I hope Asus will fix the issue with a driver update because it's really annoying.  Thanks to everyone, in any case,

Hello, I want to thank you, the 60-second on/off maintenance trick worked (maybe less too, but I haven't tested it) even though I wasn't convinced. The network card was no longer present in the device manager. The Windows diagnostic and repair didn't work. Restarting the PC didn't work either. And resetting the network card didn't work either.

Thank you!!! I'm having the same issue with this type of card! I put the computer on battery and pressed the power button for about 60 seconds (pressing the button in small bursts).
