Alienware Aurora 16X WiFi Issue
Hi My recently purchased Alienware Aurora has developed a problem over the weekend.
It no longer connects to wifi. I am currently connected on LAN.
Device manager shows drivers. but they are marked with(!)
Spent all afternoon on this. DellSupport Assist will not run!
Dell AI help is useless
When I asked to speak to a person, I was told my PC was not supported ... which is WRONG, because I have chatted before, and I am under warranty.
Any ideas other than to reinstall the operating system ?
I guess I downloaded an update it didn't like.
Second support issue in under 6 months .... not impressed TBH.
Tried a recovery (not full reinstall). Same problem.
Regards
Tim

Hi
The internet reports......
Install the correct Dell MT7925 driver cleanly
Dell has an internal defect logged for unstable Wi‑Fi on systems using MT7925 (Alienware 16 / 16X Aurora family, etc.), and the main mitigation is updating to their latest package.
On a working machine, go to Dell Support, enter your Alienware Aurora/16X service tag and download the latest MediaTek MT7925 / Wi‑Fi 7 driver for Windows 11.
Copy it to the Alienware via USB.
On the Alienware:
Right‑click Start → Device Manager → Network adapters.
Right‑click the MediaTek MT7925 / Wi‑Fi 7 adapter → Uninstall device → tick “Delete the driver software for this device” if available → OK.
Reboot. Windows will re‑detect the adapter.
Run the Dell Wi‑Fi driver installer you downloaded, let it finish, then reboot again.
Not this though.......
Fix “no Wi‑Fi option” / adapter missing
Some Aurora R16/Alienware users report Wi‑Fi disappearing entirely until they change a BIOS security setting.
Reboot and tap F2 to enter BIOS.
Go to Security.
Find Enable Kernel OS DMA (or similarly named DMA security option) and set it to Disabled.
Save and exit, then boot into Windows and check if the Wi‑Fi adapter and toggle reappear.
If it’s still missing in Device Manager, rule out hardware:
In BIOS, check that Wireless/WLAN is enabled (if there is such a toggle).
If you’re comfortable opening the case, reseat the MT7925 M.2 card and check both antenna leads are firmly clipped on.
Finally...... Contact Dell support and reference that your system has the MediaTek MT7925 WLAN and matches the symptoms of their known defect. Ask for either a driver‑level fix or a warranty swap to an Intel AX or Killer AX Wi‑Fi card (many users end up going this route when troubleshooting fails). NB: Your BlueTooth is aslso showing a problem, hence the replacement.
