I'm trying to install WiFi drivers. I read that I need to do a sudo modprobe wl, but then I get an error saying

modprobe: ERROR: could not insert 'wl': Operation not permitted

Googling leads me to believe that this is because "secure boot" is enabled on my system. I can see it enabled in my BIOS settings (ASUS motherboard).

I am dual booting (unfortunately I need Windows 10 installed as well, for gaming), and I suspect that Windows 10 needs secure boot to be enabled? I don't know.

So my questions are

a) How do I install the WiFi drivers, when secure boot is enabled?

b) If I need to disable secure boot, will that mess up my dual boot setup? Should my Windows 10 installation still work normally, if I disable secure boot?

(If it's relevant, the device I need drivers for is ASUS AC68 WiFi adapter)

EDIT: Here is why I try to do sudo modprobe wl

    Is this a USB device? I doubt that wl is the correct driver. – chili555 Apr 24 '22 at 19:04
  • No it's a "card" connected to the (PCI?) slot on my motherboard. https://www.asus.com/no/Networking-IoT-Servers/Adapters/All-series/PCEAC68/ – birgersp Apr 24 '22 at 19:05
  • I think you have misdiagnosed your problem. Look at `sudo journalctl -b 0` and see what is said about your hardware. – waltinator Apr 24 '22 at 22:57

    Let's have a look at: `lspci -nnk | grep 0280 -A3` – chili555 Apr 24 '22 at 22:57

    Does this answer your question? [My wireless/WiFi connection does not work. What information is needed to diagnose the issue?](https://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-information-is-needed-to-diagnos) – waltinator Apr 24 '22 at 23:01
  • @chili555 here's where I got the information that I need to do `sudo modprobe wl`: https://askubuntu.com/a/704150/332138 – birgersp Apr 25 '22 at 08:04

    Manufacturers can and do change the chipset over the years. Again, may we see: `lspci -nnk | grep 0280 -A3` – chili555 Apr 25 '22 at 12:15
  • I'll paste the results of that command as soon as I'm back on the computer in question – birgersp Apr 25 '22 at 12:17

I disabled secure boot, and the Windows installation did not suffer.
