WiFi Adapter Not Found

Ask Fedora

I recently upgraded from Fedora 31 to Fedora 32, but couldn’t start the WiFi as it shows no adapter found. I have previously been using Fedora 31 and the WiFi worked perfectly. I upgraded using GNOME Software application and not the terminal.

dmesg | grep iwlwifi

Doesn’t print anything, even though I’m pretty sure the wireless controller was from Intel. I know this because the first thing I did when the error occurred was run lspci and the output contained Network Controller and dmesg | grep iwlwifi too printed something, but then I connected my phone via USB tethering and Ethernet controller showed up.
I have searched all threads on this forum and made no progress, if not worsened the situation already.
Also, will doing a fresh boot of Fedora 31 restore my WiFi, because at this point, I might as well try that.
Thanks very much.

Hi there,

We need more info. Please share the kernel version (uname -a).

It’s weird that lspci don’t show your wifi adapter. Do you happen to know the chipset model? that could help in the search. Seems like a Realtek since you have a Ethernet Realtek adapter as well.

What does sudo dmesg alone returns? Post it.

Post also the result of ‘sudo lsmod’.

Try ‘sudo lshw | grep ireless’ and post it. Another option is to run 'sudo lshw | less ’ and then press “/Wireless” to find any pluged-in adapter, active or not.

Once we have the wireless chipset brand and model number you can get a proper working driver.

sudo lshw| less and then the search for “/Wireless” does find the WiFi adapter, or what I believe it is.

The kernel version,
name -a:
Linux Tanmays-Fedora.localdomain 5.7.7-200.fc32.x86_64 #1 SMP Wed Jul 1 19:53:01 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

It is weird that lspci doesn’t show Intel or Wireless anywhere and even weirder that it did before and did show Intel.
Thanks.

Ok, this is what I know, friend:

I just took a look and there are several versions of the 7265 chipset. You might want to check out first the web for ‘your laptop model+intel 7265’ to find out exactly the version you need.

Intel wifi adapters use firmware. Should be included in your kernel, but seems it doesnt, so you’ve got two options, for installation:

1.Download from Intel directly.
So, you should head here to get the latest versions:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/

or, if something goes wrong, the first version of the firmware here:

Once you have that, well you have to install the ucode.

Now the vendor says all you have to do is:

  1. Copy the files into the distribution-specific firmware directory, /lib/firmware.
  2. If the directory doesn’t work, refer to your distribution documentation.
  3. If you configure the kernel yourself, make sure firmware loading is enabled.Copy the files into the distribution-specfications

Thant means all you have to do is: ‘cp iwlwifi-7265-XX.ucode /lib/firmware’ just make shure you change XX to match fully your filename and reboot. You might want to check if there are any iwlwifi files already in your directories, you might want to back it up and rename as ‘.old’ in the firmware to avoid any conflicts.

If that doesnt work, manually load with modprobe:

sudo modprobe iwlwifi-7265-XX

Check if this did loaded the firmware and reboot to fully

lsmod
reboot

Then retry lshw and dmesg to check if its already up.

  1. Years ago, when using Ubuntu I used a iwlwifi command to install the firmware directly from repositories. It was something like ‘apt-get install iwlwifi something something’. You might want to check out if there is a version of iwlwifi in the Red Hat or Fedora repositories for you to install. But no promises there.

Well, try some of that and if you can post results.

Bye.

Thanks for the reply.
On further inspection into /lib/firmware, I found out that I already have the latest driver from Intel Wireless i.e. iwlwifi-7265-17.ucode in /lib/firmware
So on your advice, I tried

sudo modprobe iwlwifi-7265-17:
modprobe: FATAL: Module iwlwifi-7265-17 not found in directory /lib/modules/5.7.7-200.fc32.x86_64

I don’t understand why I can’t load the driver. I’m beginning to think that it isn’t a driver problem.
Also, will giving a fresh boot of Fedora 31 fix the WiFi as it was previously, because I might as well try that?

Thanks

modprobe can only load kernel modules/drivers, associated firmware is then requested & loaded by those modules. Which firmware to load is programmed into the module - that should be listed in the output of modinfo <module>

What happens when you try to manually load the intel wifi module?

$ sudo modprobe iwlwifi

Thanks for all your replies, but this problem, I guess, lies with Fedora 32 and is not a simple missing or unloaded driver issue.
@lcts, I did $ sudo modinfo iwlwifi and indeed the driver was programmed to load into the module and was present in the output from the command. As @nachosan stated, it indeed was weird that lspci didn’t show the WiFi adapter.
So, I gave Fedora 31 a clean install from the Live USB and got a working WiFi. After that I tried Fedora 32 from another Live USB and it still showed “WiFi driver not found” (go figure). Anyway, no Fedora 32 for me, I guess I’ll just have to wait for Fedora 33.
Cheers.

There have been a lot of reports of wifi-card-not-detected issues or similar for F32 recently. I suspect there are some issues with the most recent kernels.
