So, I have a new Lenovo Ideapad L340 15IRH Gaming laptop, and I've been trying to use Linux on it. However, in every distro I've tried so far with this new laptop, my wifi and bluetooth just won't work. So, after about a month of distro hopping, I finally landed here (I'm currently running Garuda GNOME), and to my great surprise, the bluetooth works flawlessly here. So, I do wanna congratulate the team on this great job, because in my experience this is the best looking distro and the only distro which lets me use my bluetooth.
However, the wifi issues continue to persist. When I turn on my computer, it connects automatically, but in about a minute I get an error notification saying:
Activation of Network Connection failed
And I lose my connection.
I have a Realtek 8822be Wireless card as mentioned in the title, and this is the dmesg output:
[ 51.978178] rtw_8822be 0000:07:00.0: failed to read ASPM, ret=-5
[ 51.978276] rtw_8822be 0000:07:00.0: stop vif 8c:c8:4b:f2:6f:71 on port 0
[ 53.978359] rtw_8822be 0000:07:00.0: failed to poll offset=0x5 mask=0x2 value=0x0
[ 55.978904] rtw_8822be 0000:07:00.0: failed to poll offset=0x5 mask=0x2 value=0x0
[ 55.978911] rtw_8822be 0000:07:00.0: mac power on failed
[ 55.978913] rtw_8822be 0000:07:00.0: failed to power on mac
So I was hoping I could get some help fixing it.
Thank you!
PS: During updates I also get an error saying that /sys/module/pcie_aspm/parameters/policy can't be written to. Could that be the cause of the problem?
I just installed the new drivers and rebooted, and now it doesn't even detect the wifi card. I'm guessing it's because I didn't disable the old drivers. So, how do I disable them?
Also, these new errors have popped up in dmesg:
[ 11.964409] rtw_8822be 0000:07:00.0: failed to setup chip efuse info
[ 11.964414] rtw_8822be 0000:07:00.0: failed to setup chip information
and,
[ 11.996979] Error: Driver 'rtw_8822be' is already registered, aborting...
If the above suggestions brought no improvement that brings us back to the proprietary Realtek driver. Perhaps the rtw88-dkms-git driver installer did not create the required blacklist file. There are a few realtek installers that are missing this important step. If you wish to retest the proprietary driver follow these instructions:
Create a file /etc/modprobe.d/rtl8822be.conf
Add the following lines to the conf file (and save the changes):
blacklist rtw_pci
blacklist rtwpci
Then, again install rtw88-dkms-git and reboot.
Sorry but I'm done for now (commitments), good luck.
For sure Windows can have side effects on wifi cards (and also bluetooth if I remeber correctly) in general, but I guess this depends also on the specific card model.
I think it would be anyway important at least to make sure that Fast Boot is disabled in Windows.
I don't think it's a hardware issue because it works perfectly well with windows. And it does work sometimes even in Garuda, but only if I boot into windows connect to the internet and then reboot into Garuda.
That’s the problem, Windows.
It always works when Win does not block the hardware.
I can’t explain it well, but that’s why Garuda doesn’t recommend this dual-boot.
Secure boot was already disabled. I've now disabled fast boot. The wifi seems to be working at the moment. But I guess only time will tell if this is a permanent fix or not.
I've had the wifi work for a few minutes and then die a lot of times before.
Fastboot breaks lots of thing as it does not release the hardware properly to other systems.
Its a windows thing to make it feel like its booting faster
I think it worked. I disabled some powersaving options in windows' device manager, disabled fast boot and mac randomization, and I'm now sitting here connected to the internet and to my bluetooth earphones, with no external adapters. All that's left to see is whether this fix can survive the night.
If it's all working when I boot into my computer tomorrow morning, I'll mark this question as solved.
