WIFI not working in linux 5.9.1 #176

Closed mrfluffy-dev closed 3 years ago

mrfluffy-dev commented 4 years ago

Seems like the driver has an incompatibility with linux 5.9.1 Can't tell what is causing the problem but I have seen comments saying something about RFE all I can tell you is that the wifi keeps connecting and disconnecting non stop.

Thanks for the help.

tomaspinho commented 4 years ago

Blacklist rtw88, then make sure this module is actually installed and running.

mrfluffy-dev commented 4 years ago

The rtw88_8821ce module was the only one that resembles this name there was the 8821ce as well tried blacklisting them one for one and when i blacklist the rtw88_8821ce I had no wifi ran a mkinitcpio can't see the rtl8821ce model and modprobe can't find it even went as far to look in the /lib/modules/linux*/modules.alias file and the module is not there

tomaspinho commented 4 years ago

You need to blacklist rtw88_8821ce, but keep 8821ce (which is the module in this repository).

ukbeast commented 4 years ago

Native rtw88 definitely has a lower signal strength, 23% vs. 70% 8821ce. On Debian sid, (5.9.0) I followed the instructions and blacklisted rtw88_8821ce. works like a charm.

Thanks @tomaspinho and everyone else.

@mrfluffy69 did the module build without any errors under dkms?

mrfluffy-dev commented 4 years ago

Funny enough using 8821ce just doesn't work for me im using the native rtw now because blacklisting it just gives me no WIFI sadly and yes I installed the package from the AUR with no problem even tried using the git clone method with no luck sadly but I appreciate the help a lot I'll give it another shot

tomaspinho commented 4 years ago

@mrfluffy69 that reads like a borked installation. Please follow the removal instructions in the README and attempt a clean reinstall.

mrfluffy-dev commented 4 years ago

Thanks for all the help sadly removing all traces of it and reinstalling it with the rtw88 module blacklisted didn't do the trick the 8821cl module just doesn't want to do anything with my card it seems but Thanks for the help I do appreciate it

ukbeast commented 4 years ago

Make sure to blacklist first and reboot before running the dkms-install script, I'd suggest not using aur. Run dkms-remove and start from scratch with using dkms-install after.

slapelachie commented 4 years ago

Tried blacklisting the rtw88 module but no dice even after rebooting and then installing through dkms

Had my laptop in suspend and re-opened it later, for some reason it now works (using rtl8821ce not rtw88).

Only difference from before is I am now using an old commit (18c1f607c10307a249be82cb398fb08eb7857a9f) so it may be some change after this commit that causes the wifi scanning to not work.

mrfluffy-dev commented 4 years ago

Interesting sadly my WIFI card just doesn't work cant find it as an available card if I use this driver quite sad coz I have been using this driver since I got the laptop now it just doesn't want to work and its quite sad forced me to go get another driver it works but I have to compile manually everytime i get a new kernel and being on Arch that is going to get annoying fast so I hope I can switch back to this package fast

  1. blacklist rtw8821, reboot
  2. reinstall rtl8821ce-dkms aur package, reboot

but my wifi still not working, why?

I see I am not loading the kernel driver and cant find a way to manually do it. So I think I found the problem but I don't have the solution (ps this is a clean install of arch only modding I did was blacklist the trw88_8821ce module)

Both of you seem to be experiencing the same issue: having both modules available but none getting loaded.

Can you post the output of dmesg | grep rtl and dmesg | grep rtw?

mrfluffy-dev commented 4 years ago

don't have the slightest idea of what changed but the driver is now running the rtl8821ce one and the wifi works again all I did was reboot (and I did that a lot over the past few hours trying to fix it)

but here is my output

energygreek commented 4 years ago

@tomaspinho thank you! it still doesn't work, what i have done is uninstall rtl8821ce-dkms aur package, blacklist rtw88_8821ce, after a reboot, i got no output from lsmod | grep 8821 . finally i install rtw88_8821ce-dkms package. after reboot, the wifi still does not work.

Both of those outputs of dmesg look good to me, what issues are you experiencing? Does the card come up on ip link, for example? Can you scan networks at all?

@tomaspinho This also happened to me and one of the Reddit user who posted on r/archlinux. It is quite weird that it starts working automatically.

Just to be clear both me and the Reddit user had the same issue our card was being detected properly. But was not able to scan the network. it just keeps showing no network found as @karl-tye is mentioning. I even downgraded my kernel to arch-lts but it did not even work there. which was quite weird too... I even tried blacklisting ideapad_laptop module as suggested in README and rebooted 2 times, but was still not working.

I then thought to re-install as even changing the kernel was not doing anything. So I dual booted into my windows system to do some other stuff and after some time I booted into linux again and guess what is started working!

Glad to hear that it's working for others, however it is still not working for me after a few reboots. I think it may be linked to this post from the arch linux forums

Upon further inspection and research, I have discovered it is because my RTL8821CE chip is RFE2, which is not supported by the kernel driver yet.

mrfluffy-dev commented 4 years ago

The rtl8821ce driver works with it the rtw88 does not work with RFE2 so run lspci -k to see what kernal driver the device is trying to use at this moment

tomaspinho commented 4 years ago

It's really though helping you guys without the hardware myself. Blacklisting rtw88 correctly and rebooting once should've fixed the problem for you all, given a correct installation of rtl8821ce.

mrfluffy-dev commented 4 years ago

Well my /etc/modprobe.d/blacklist.conf did the trick not right away even after blacklisting it didn't tun the modules but kept using the wrong kernel driver then it just suddenly changed oo and the contents of my /etc/modprobe.d/blacklist.conf is

blacklist rtw_8821ce blacklist rtw88_8821ce

The rtw_8821ce shouldn't be on your system i installed it in an attempte to get wifi but didn't work well so after this only the 8821ce will run

karl-tye commented 4 years ago

Hopefully we can get to the bottom of this soon. @tomaspinho if there is any other information you think I can provide then please let me know. I'm not fond of having to carry a 10 meter Ethernet cable with me when I need to access the internet :stuck_out_tongue_closed_eyes:

HugoForrat commented 4 years ago

Hello,

First of all, I would like to thank @tomaspinho for your work on this driver, I appreciate it immensely.

I hope you don't mind if I add myself to the list of users whose card stopped working after the Linux 5.9.1 update, even after blacklisting the new modules. I am running Arch Linux, without secure boot.

Here is the content of my /etc/modprobe.d/rtw88_blacklist.conf:

blacklist rtw88
blacklist rtw88_8821ce
blacklist rtw88_pci
blacklist rtw88_core
blacklist rtw88_8821c

Here is what I believe is the relevant part of lspci -k:

dmesg | grep rtw doesn't return anything.

And here is the output of sudo ./dkms-install.sh after my manual installation:

I should add that I use this card as a Wifi Access Point and as a way to connect to my bluetooth headphones. In this first case, I can run the usual nmcli command without any error but I am unable to find the network with my phone. In the second, I can run power on in bluetoothcl but when trying to connect <my_device> I get an Failed to connect: org.bluez.Error.Failed. My card also does appear when running ip link. All of this makes the bug quite strange. I am of course available for more information if someone has any idea about what the problem could be.

PinkD commented 4 years ago

I upgraded my kernel to 5.9.1 yesterday and the driver seemed not working. Then I degraded my kernel to 5.8.9 and reboot(like I always did in the past), the driver still did not work. I tried to compile the newest version driver from this repo and it still did not work. I gave up and used my wired card. But today I found my driver works again. It's really weird. Is there any difference between reboot and poweroff-and-on? Or I missed some thing important?

karl-tye commented 4 years ago

I have joined the group of 'restarted and it worked'ers! I have outlined the steps I took below. Hopefully this can help anyone who is still having this issue (@HugoForrat).

cd .git/rtl8821ce
sudo ./dkms-remove.sh
cd /var/cache/pacman/pkg
sudo pacman -U linux-5.8.13.arch1-1-x86_64.pkg.tar.zst linux-headers-5.8.13.arch1-1-x86_64.pkg.tar.zst nvidia-440.100-1-x86_64.pkg.tar.zst nvidia-settings-440.100-1-x86_64.pkg.tar.zst nvidia-utils-440.100-1-x86_64.pkg.tar.zst
reboot
cd .git/rtl8821ce
sudo make clean
sudo ./dkms-install.sh
mkinitcpio -P
reboot
tomaspinho commented 4 years ago

Is dkms on Arch no longer doing mkinitcpio automatically on dkms install? That would explain the multiple reboot issue - the module would not be included properly in the subsequent upgraded kernel.

tomaspinho commented 4 years ago

If someone can reproduce @karl-tye's solution, maybe we can add it to the README afterwards?

darkretailer commented 4 years ago

It didn't work for me. But in my case the same problem occurs if i boot in Windows. But only since I've updated the kernel for arch.

I did the steps but no networks were avaiable - so in windows too.

So i disassembled my notebook but the antenna cables were ok. I started windows again and it works. So i tried Arch with lts kernel and it works too. Booted again but with 5.9.1 and the problems occurs again. Now back to windows => again problems no networks available. I left the pc off for a while. And now it works again with lts 5.4.

So it seems that booting up linux 5.9.1 with the current version of this driver causes a problem which survives a restart.

Makes this any sense to you?

Lenovo L340 Arch Linux - 5.9.1-arch1-1 / linux-lts 5.4.72-1 | Windows 10

jeancf commented 4 years ago

Hello all. I am joining the party with a Lenovo Ideapad L340 with an RTL8821CE Wi-Fi chipset that I have been happily using for months on MANJARO with the AUR driver rtl8821ce-dkms-git. But when I rebooted after trying the linux-5.9 kernel, no more Wi-Fi connection was available in KDE Plasma's Network Manager.

I tried removing and reinstalling the driver, I tried rtl8821ce-dkms instead, I tried using the 5.4 and the 5.8 kernel with the same result. I have unfortunately not reached the "rebooted and it worked again" stage and I am happy to contribute to the investigation.

Here are more details:

Sorry for the late reply: unfortunately, @karl-tye's solution didn't work for me at least not as is. Doing

sudo pacman -U linux-5.8.13.arch1-1-x86_64.pkg.tar.zst linux-headers-5.8.13.arch1-1-x86_64.pkg.tar.zst

and then reboot immediately broke my booting process and I had to find a live USB to put back the updated kernel. I think I will try the solution @darkretailer which is to use linux-lts.

Also, I should add that, like @darkretailer and @jeancf, who still have the issue, my computer is a Lenovo L340.

mrfluffy-dev commented 4 years ago

@HugoForrat my Wifi works now on 5.9.1 and I also have a L340 so I don't think It has to do with the device itself I cant give you a reason it is happening just that I spent hours trying to fix it and just a random reboot I did fixed it

I'm glad to know that there is still hope, but it's been about about a week, I've made dozens of reboots and it still doesn't work... I've just tried booting with the linux-lts kernel and unfortunately, it didn't change anything (I redid the whole manual installation after booting in linux-lts), so I'm really at loss for idea now... Only thing left is perhaps wiping my whole system clean and installing a fresh Arch with linux-lts, and hoping to avoid the problem that survives a restart that @darkretailer was talking about.

Hi @HugoForrat, when you say that it broke your booting process it could have been your video drivers not working with your new (old) kernel version. I had the same problem and had to uninstall my nvidia packages and instead use nvidia-dkms.

Sorry, I worded this poorly, you weren't responsible in any way, but no actually, I meant that GRUB was looking for the kernel 5.9.1 to boot but couldn't find it; I think it was because I didn't run mkinitcpio nor grub-mkconfig after downgrading. But do not worry, I've fixed this issue, and I am back in step 1.

jeancf commented 4 years ago

I found a log trace that may be interesting. Look at the last 3 lines.

The scan is not taking place because some timer related to a previous scan has not expired yet. It seems to need 4921 (what? ms? s? m? h?) before re-running. This would explain why people are suddenly seeing the functionality coming back to life. It is not after a reboot but after the expiration of some time.

What is this timer though and how to override it or set it to 0?

jeancf commented 4 years ago

OK. So the issue discussed here was resolved for me by the latest Manjaro stable update… albeit for only a few minutes.

I performed today’s stable update on my system then rebooted with kernel 5.4 and Wi-Fi woked again with the rtl8821ce driver. Great!

Then I rebooted with kernel 5.9 which is also installed on the system. There Wi-Fi did not work. I tried blacklisting rtw88_8821ce and rebooted but it did not work either.

BUT when I finally booted again with kernel 5.4… No Wi-Fi. I tried the usual since: remove blacklisting, de-install rtl8821ce, de-install 5.9, re-install rtl8821ce, reinstall kernel 5.4, nothing works. I also tried kernel 5.8 with no better result.

It looks like it is booting with 5.9 (and its rtw88_8821ce driver) that screws everything up but I don’t understand why.

rany2 commented 4 years ago

Very strange. I can't reproduce.. Are you sure you're blacklisting properly?

P.S after you make changes to /etc/modprobe.d or /etc/default/grub be sure to run mkinitcpio -P and grub-mkconfig -o /boot/grub/grub.cfg respectively

jeancf commented 4 years ago

To make sure I removed the 5.9 kernel and removed any blacklisting from /etc/modprobe.d. I removed and reinstalled the driver. I manually ran mkinitcpio -P and grub-mkconfig -o /boot/grub/grub.cfg and rebooted. But still no Wi-Fi.

The situation is the same as described above: rtl8821ce driver is loaded but no wireless scan seems to take place.

rany2 commented 4 years ago

@jeancf After a reboot it seems to have mysteriously stopped working again and I got the same no wireless scan issue. It seems like the driver occasionally stops working. It sometimes works and sometimes doesn't. I wonder what may be causing that.

I was impatient so I just swapped the card with an atheros chip but I wonder if trying to unload and load the module fixes it.

jeancf commented 4 years ago

@rany2 Thanks for the suggestion. Removing and re-adding the module does not change anything.

lsmod | grep 8821 returns the same before and after re-adding:

This might be a stretch, is there a wifi switch/key? Try switching it off and on.
