So my laptop has a wireless card, but AlmaLinux can’t see it: in the Gnome interface, I can’t switch Wi-Fi (“No Wifi adapter found”).
However, if I run
hwinfo --pci,
I can see that, indeed, there is a Wifi adapter on this laptop.
My understanding is that this situation stems from BIOS (that’s the tricky part, may detail that if needed), and I try to found any way to re-activate Wifi from CLI or elsewhere.
Then I tried
nmcli radio wifi on
nmcli radio all on
but still, I can’t see the Wifi adapter in Gnome.
Therefore, I would like to access, and possibly update, the BIOS configuration items in the laptop running AlmaLinux.
To access this information, I tried those commands:
dmidecode
hwinfo
But how could I update the Wifi (Wireless) adapter flag in the BIOS from AlmaLinux ?
As you did notice, the stock kernel does not have a driver for it:
$ modprobe -c | grep -i 10ec.*c821
$
The next place to look for is ELRepo: http://elrepo.org/tiki/DeviceIDs
Alas, not there either. (ELRepo has drivers that Red Hat has chosen not to include in RHEL.)
By the way, @jlehtone, would you have a suggestion please about how to check BIOS / EFI parameters from AlmaLinux? (nb: it’s understood advanced settings for instance should be handled with care, and I am thinking of reading/dumping these settings, logs, etc.).
I further searched the topic and found for instance the efitools package, with the manual here:
Wondering if there is already a similar tool installed in RHEL/AlmaLinux or which could be installed?
