Realtek 8852BE not working properly

Issues & Assistance Networking Support
1

I just got a new laptop with a RTK8852BE wifi card, and after installing Garuda on it (what else would you use amirite?), I noticed that my wifi is behaving very strangely. I can connect to networks just fine, but after connecting the internet is basically unusable, any page will take 30+ seconds to open, and it often won't get rendered properly, I tested this 3 ways, at work with a 5GHz connection, at home with a 2.4GHz connection, and I tried it with USB tethering from my phone, and I had the same result each time, so I'm assuming the Realtek card might not be the only issue. I tried installing both variants of rtk89 from AUR, as well as directly from GH, and it changed nothing, additionally, Garuda Network Assistant doesn't detect any drivers for the card (tho I'm assuming this is normal as the same thing happens on my PC where everything works normally).

First time posting here, so I'm sorry if I missed something, but I tried looking through both linux-related forums and arch-related, and I found nothing that solves my issue, so this was my last resort. Let me know if you need any additional info, and thank you in advance

Try other kernel

That didn't seem to do much, tho one interesting thing did happen.
I tried 3 other kernel versions:
6.3.1-AMD
6.3.1-arch
6.1.27.1-lts

On 6.3.1-arch and 6.1.27.1-lts the result was identical, it connects very easily but it's effectively unusable, on 6.3.1-AMD however, it wouldn't even detect my WiFi card at all. I tried using USB Tethering just to run garuda-update, maybe it'd help, but it couldn't hold a stable connection for long enough, which again leads me to believe that the issue isn't the wifi card itself, otherwise USB Tethering would run just fine right?

They wrote about black listing some driver in the link, but IDK nothing about this part.
So wait for other or try by yourself, please.

Create a file /etc/modprobe.d/rtw8852be.conf with the following contents:

blacklist rtw_8852be

and reboot.

I'm not a blacklist karate-kid :slight_smile:
Give also a look at:
https://wiki.archlinux.org/title/Kernel_module#Blacklisting

If still not working, this could be the culprit (I expected this to be fixed in kernel 6.3), but there seem to be a workaround (see comment #2, but again, read entirely):
https://bugzilla.kernel.org/show_bug.cgi?id=217207

Edit:
Sorry, I really think you can disregard this post...
Rereading the bug description I see that the problem was different (WiFi was not working at all due to firmware not found).
I hope the other solution/driver, with blacklisting, has better luck.

Thank you for the suggestion, but I just tried something completely different, and it turns out that it's not the wifi card at all.

In my previous laptop, I also used Garuda, and it had a 8821CE or something like that, and it worked perfectly fine, so I took it out, replaced it with the 8852BE in the current one, and the issue persisted, I tried installing the driver for 8821CE and rebooting, nothing. I do have windows in dual boot, and I have secure boot disabled as well as fast startup in windows, but again, the issue definitely doesn't seem related as wifi does actually still work, it's just completely unusable. I would often get DNS related errors when doing things like paru -S *package name* or garuda-update, but it'd eventually start working, same for the browser, it might take a while, but it does connect eventually (most of the time).

If anyone has any other troubleshooting steps I'm open to anything at this point. It's starting to look like it's not a Linux/Arch/Garuda issue at this point and Lenovo did some BS to it, but I'm all out of ideas.

Are you dual-booting with Windows? If so, you will need to change the default shutdown method Windows uses. The “fast startup” feature that is enabled by default is known to interfere with the network card and other resources when booted to another OS.

If you are not dual-booting with Windows, run a basic ping to test for dropped packets. First point the ping at your gateway.

ping 192.168.0.1

Obviously change that IP address to whatever your gateway’s IP is.

Test an external IP address:

ping 9.9.9.9

Test a ping that uses DNS.

ping archlinux.org

If some tests have dropped packets but not others, that will be informative.

Hi, thanks for replying.

As I already mentioned in my comments, fast startup is disabled. I have already tried pinging my router, but not the rest.

Router: 10 received, 0% packet loss, time 9016ms
External IP: 10 received, 0% packet loss, time 9013ms
archlinux.org: 10 received, 0% packet loss, time 67883ms

Another thing I find fairly interesting is that if I run garuda-update, during the Synchronizing package databases step, core, extra, community, and multilib repos get retrieved very quickly, but garuda, chaotic-aur, and blackarch always fail to download.

Please show what you have in /etc/resolv.conf.

cat /etc/resolv.conf

# Generated by NetworkManager
nameserver 84.200.69.80

Nothing else

Edit:
I checked the same thing on my desktop PC (connected by LAN but still) and the contents are

# Generated by NetworkManager
nameserver 192.168.100.1
nameserver fe80::1%eno1
12

It looks like your desktop machine is using the gateway as a nameserver (that's pretty common). If you have not set it yourself, the gateway probably has a nameserver assigned by your ISP.

You can try changing the DNS server on the laptop to OpenDNS or something else, to see if the issue is related to the DNS server, but my hunch is the network card is to blame after all.

As I mentioned earlier, it can't be the network card, as the issue persists when using USB tethering, and also with a different network card that has worked perfectly fine in a different device.

Also, setting the DNS to 8.8.8.8 did nothing (assuming I was expected to change it in connection settings)

Hey guys, issue solved!

Turns out that I (probably?) missclicked during the first time setup and DNS was set to DNS.Watch by the Setup Assistant, which seems to be either broken or misconfigured. Anyway, after resetting it everything seems to be working perfectly smoothly. Sorry for wasting everyone's time!
