15 R4, driver issues
I have a 15 r4. After a recent fiasco with himachi somehow deleting my Killer wireless wifi drivers, I did a full factory reset. Now even using the wifi driver downloaded from the page about my computer, they won’t install. I cannot use wireless wifi and I don’t have an Ethernet cable though the driver for that still work. So if anyone is able to give me any help I would really appreciate that.

Hi @Bob joe thank you for sharing your install Dell driver problem.
Alienware 15 R4 Drivers & Downloads includes click on [Check for Updates] box, which will automatically customise and download drivers for you.
However do not select the BIOS updates, these must be manually applied consecutively (one by one), and not jump to the most recent version. You may decide not to update BIOS if system has overclocking CPU that you do not want disabled by Dell.

Bonjour,
je viens de mettre à jour mon BIOS sur un Alienware 15 R4, j'ai donc aujourd'hui le 1.20.0, 09/05/2022. Est-ce le dernier ?
Bien à vous

Hello @chris de Nantes , while there is discrepancy between firmware posted date and released date, you do have the latest BIOS firmware for your Alienware 15 R4.

Well you can try the following:
Check whether Windows detects your Wi-Fi card.
Remove the broken driver entry.
Check the driver package.
Try installing the driver manually.
If you don't have another computer or USB drive
