Wifi not loading and slow when rebooting from Windows

Nacho · September 16, 2020, 7:54pm

Hello everyone,

A few weeks ago I installed Manjaro KDE and Windows 10 in my laptop and got the dual booting working perfectly. Since then I have had some issues with Manjaro but everything works mostly fine.
Eventhough, I am having two problems with the wifi connection which I have not managed to solve.

The first one is that sometimes when I boot the wifi driver does not load at all, just as if there is no wifi card in the laptop. Once this happens I know no way of getting it back and for the moment it just comes back as mysteriously as it left. Today I managed to get it working when connecting via ethernet to the internet but other times this has not worked. The only hint I have is that it might be related to Windows because it often happens after I boot into Windows but I am not sure this is always the case. When the wifi is working the result of the command inxi -Fazy is the following:

Note that when this problem happens in the network section for the wifi card the driver is listed as N/A (instead of iwlwifi).

The second problem, which might be related, is a slow internet speed getting most of the time 0 bytes per second both for upload and download of data.

Any help will be most welcome.

Thank you very much

There can be several reasons for this. Does the failure of your wifi to load follow a pattern? For example, does it routinely work from manjaro session to manjaro session, but fail when you leave a windows session and boot into manjaro? If that’s the case, this is a known issue–sometimes windows doesn’t relinquish its ‘hold’ on the adapter, so the bios still things it’s spoken for. Try removing your battery and pressing the power button for 20 seconds or so, then reinstalling the battery and booting into manjaro. Can you let us know if that works?

Nacho · September 17, 2020, 1:57pm

I think it must be related to what you are commenting, it has happened twice in a row after booting in windows and before that it didnt happen for a long time while only booting in manjaro. I cannot remove the battery although there is some sort of battery reset button in the PC that I could use. For the moment I think is not necessary because I have also noticed that after leaving the laptop turned off for the whole night the wifi usually comes back in the morning.

Would this explanation relating Windows to the problem also explain why the wifi is so slow?

Is there a fix to this problem then? Could I update the windows drivers or modify some settings in the BIOS?

Fabby · September 17, 2020, 2:08pm

That is called a “side effect”: the hardware is certified for Windows and there is a bug in the Windows driver or UEFI firmware. The solution to this is to always shut down Windows and then press the power button again to boot into Manjaro (Cold boot) I.E. Do not reboot from Windows and then start Manjaro

Please give us the output of:

 nmcli device wifi list | grep "*"

P.S. It’s also better to ask one question per … well… Question! because it’s easier to find one expert per question than one expert that has an answer to both questions. (as both are networking questions you’re in luck though)

Nacho · September 17, 2020, 2:20pm

The solution to this is to always shut down Windows and then press the power button again to boot into Manjaro (Cold boot) I.E. Do not reboot from Windows and then start Manjaro

I think this is not enough because I always turn off the laptop and boot into a different laptop, I think the key is to wait for a given amount of time (or reset the battery as @mendizale suggested).

Sorry about the two questions I though it would be better to explain all the issues relating the wifi card just in case both are consequences of the same problem. The result of nmcli device wifi list | grep "*" is:
* E2:41:36:9A:AD:68 INTERNET_COMPANY Infra 1 130 Mbit/s 65 ▂▄▆_ WPA2

Fabby · September 17, 2020, 3:14pm

Please, consistently:

Shut Windows down completely
Wait for 1 second
Turn the machine back on
Boot Manjaro

Because there probably is a bug in the Windows driver or UEFI firmware. This is called a Cold boot. I.E. Do not reboot from Windows and then start Manjaro (Warm boot)

That’s good, so that’s not the problem.

Try the following:

disable power saving by adding power_save=0 to /etc/modprobe.d/iwlwifi.conf
If the above doesn’t help, try the 5.4 LTS kernel (Intel had some issues in the 5.7 kernel, maybe they’re not all gone), keep the parameter above there as well
Please provide the full contents of /etc/modprobe.d/iwlwifi.conf

Nacho · September 17, 2020, 4:24pm

Thank you for the feedback. I have no /etc/modprobe.d/iwlwifi.conf file, should I create one with root permissions?

Fabby · September 17, 2020, 9:53pm

Yes, please.

Nacho · September 22, 2020, 10:56am

After some testing I can confirm that both solutions you gave are working, it has been enough to edit the wifi configuration file to improve the speed and letting a few seconds between boots is often enought to ensure the wifi gets loaded.

Thank you for the help!

Fabby · September 22, 2020, 11:08am

I’ve edited the solution and the title of this conversarion to include all scenarios.
Please verify so the next person that has the same problem as you will find a ready-made solution…

pobrn · September 22, 2020, 11:14am

I recommend turning off “fast startup” in Windows if you have a dual-boot configuration. Maybe your problem is related.

Fabby · September 22, 2020, 11:32am

Please confirm that “fast startup” was already disabled? (or wasn’t)

Thanks @pobrn: I should have asked that first!

Nacho · September 23, 2020, 8:40am

Hi! Yes I already had it disabled as part of the installation of manjaro in dual boot with windows.

Nacho · September 23, 2020, 8:42am

Yes, your edit looks perfect to me, thanks for taking the time!
