Fresh-Installed 37 over 33; wifi is gone!

Ask Fedora
, , , ,
1

I was expecting the install procedure would ask me to activate wifi but it didn’t. So now I have a no-network laptop.

Until yesterday, wifi has never been a problem under Fedora 2x to 33, but upgrade to 35 was failing, and 35 was unsupported so advice was to do a clean install. I’ve now done so.

I’d like to just go over to Windows and check but my GRUB has also been wiped out and I can’t figure out if there’s a way to boot to the Windows partition from the Boot Manager on this Thinkpad T470p.

From googling around, I’m not seeing how to fix this but I will provide info that others seem to ask people with similar problems to provide.

Settings->Network only shows Wired and VPN, no Network Proxy.

ifconfig doesn’t see a wifi at all, not even one that’s down:

Check that you have iwl7260-firmware-1:25.30.13.0-148.fc37.noarch. This supports Intel 7000, 8000, and 9000 wifi.

Look for the section in dmesg where the kernel loads the wifi driver. Here, with Intel 9560, searching on “iwl”:

% dmesg | grep -F iwl
[    6.168537] iwlwifi 0000:00:14.3: enabling device (0100 -> 0102)

Thank you George!

I didn’t know dmesg. I grep it for iwl and see only two lines:

0000:03:00.0: enabling device (0000 → 0002)
probe of 0000:03:00.0 failed with error -110

Googling, I found this page: 214557 – mt7921e: probe of 0000:05:00.0 failed with error -110

It suggests a cold powerdown without AC. Sounds like the equivalent of “turn it off, and turn it on again, and see if it suddenly works.”

4

Sorry, dmesg has no more iwl info after the cold reboot…

5

The link you found is for a different wifi chipset. A cold start can be needed for some wifi
configurations when a previously loaded driver (for PXE boot or wifi) conflicts with the linux driver. That should not be an issue with Intel cards.

I think error-110 means initialization failed – usually due to lack of correct firmware, possibly due to incorrect parameters to modprobe. Did you check that you have the firmware package mentioned above?

You can check without rebooting after installing the driver package by manually loading the iwlwifi module:

First, use -nv for a “[n]othing-done [v]erbose” dry-run:

$ sudo modprobe -nv iwlwifi

Then if there are no errors run without the dry-run (n) option. You should see a normal wifi initilazation in dmesg.

modprobe -nv iwlwifi

… no output?

7

If you installed the driver package then rerunning the command without the “n” should enable wifi.

8

Many thanks for your help with this so far George.

OK after running that without the n (just -v, right?) (which produces no output) I do nmcli d show and still no wifi. nmcli radio all still shows wifi hardware missing. dmesg doesn’t show anything new, and specifically doesn’t show a new driver, just the two lines "enablinng device 0000->0002, followed by probe failed -110. lsusb -v -v -t doesn’t show anything new.

Perhaps I misunderstood what you meant to do? Sorry I’m not experienced on the current-day sysadm and probably don’t understand things that would be obvious to many…

You still haven’t told us whether the current 'iwl7260-firmware.noarch : Firmware for Intel(R) Wireless WiFi Link 726x/8000/9000 Series Adapters` (recently updated) is installed on your system. The 110 error usually means you don’t have the right firmware for your device.
[edit name and description of firmware package]

10

OK, I’m not sure how to verify if it’s on my system. I tried the command you gave and no output, and no apparent other effect.

So how would I go about getting it onto my system?

Also odd that it wouldn’t be available: T470p was I would have thought a pretty popular machine.

11

sudo dnf list installed \*firmware\*
sudo dnf install iwl7260-firmware

Edit, added installation.

I’m finding this page: iwl7260-firmware - Fedora Packages

I don’t know exactly how to install it. I think I can shuffle some gear and put the laptop on an ethernet cable, which would let me access the net, but I don’t know how to actually download this thing. Is it dnf? rpm? yum? Or something else? Or is it easy to download from Windows then carry a memory stick to the laptop?

13

The package info you can check like:

sudo dnf info iwl7260-firmware
If you want to read before install.

sudo dnf install iwl7260-firmware

Thanks, I could run that if I had a network, but the problem is: without wifi, I don’t have the laptop on the LAN. To hook a LAN to the router I would need some help to move furniture to get to the router, and to disconnect my Synology disk array which is my only LAN cable…

Is there a way I can download the needed files on my PC? Then copy on a memory stick?

You’ll also want to download, iwlax2xx-firmware (weak dependency)

Hey, that’s a good command to know, thanks.

sudo dnf list installed \*firmware\* shows (along with 25 other things)

iwl7260-firmware.noarch 1:25.30.13.0-140.fc37 @anaconda

So I guess the problem isn’t that I’m missing the driver, but something else…

17

That shows the original installed version when installing F37. (reflected by the @anaconda there)
The current version is

# dnf list installed iwl7*firmware
Installed Packages
iwl7260-firmware.noarch                                            1:25.30.13.0-147.fc37                                            @updates

It seems the best fix is to somehow connect the laptop to the internet and do a full update.
sudo dnf upgrade --refresh then see if there is a change.

The issue may not be the driver not installed, but that the driver (and kernel) are not fully updated.

18

I’ve been in similar situations, so now have a USB wifi adapter that can provide wifi when cables and built-in wifi fail. Such adapters are not expensive, but due diligence is needed to ensure there is robust linux support. Plugable is one vendor that often supports linux.

The problem is that multiple packages may need updating together. It would be useful to know if you have a way to boot the PC with working wifi, e.g., the F37 Live Image.

  • Which installer did you use: Live Image, Standard Image, or Netinstaller?

  • If you have the Live Image, does wifi work there?

  • Did you install any updates, or are you using what you got from the initial install?

19

I used the most obvious ISO, but can’t remember if it was called “standard” or what. I see I should have recorded that.

Your advice sounds good and practical but in fact I have a ethernet cable for my disk array. The router’s pretty inaccessible but I can just power down all the other computers in the house, power down the disk array, and do the upgrade under my desk using its cable.

20

If you used the ISO to create a bootable USB key, you should be able to mount the key to see what it contains. Please let us know how the update goes. Any added details could help us understand where things went wrong.

The take-home from your experience is 1) if available, use ethernet for OS installs (and it is preferred for upgrades), and 2) upgrading should be done right away to protect you from already fixed issues.
