Slow Network Speed Troubleshooting

mdoverl · 1 December 2022 03:29

I'm abandoning Windows 11 on my daily driver due to no boot issues after system updates that would occur once every 3-4 months it seems. I've been running Manjaro for a longtime on my workshop computer. The no boot issue is easily fixable, I'm just tired of windows.

My network speeds are stuck in the Bs to KiBs and never reach MiBs. These slow speeds occurs on both Ethernet and WiFi. I've ran a couple other Arch flavors on here and didn't have an issue with the network speeds. I'm able to browse most web pages from FireDragon right now, as a matter of fact, I'm writing this post from the same machine.

I'm guessing I need a different network driver being that my system is somewhat new. I just have no clue how I should look up the proper driver.

I've pasted the garuda-inxi output below in a collapsible box.

I need to learn to cross reference the network info from below and figure out where to look to find the correct drivers.

If anyone has the time to teach someone how to fish, I would be thankful.

Speed test turned out well, which is strange

mdoverl · 1 December 2022 03:57

This may not be driver related. I downloaded a few browsers to test. Falkon and Vivaldi do this wild blinking on all web pages and doesn't play any videos. Edge (don't shoot me), worked just fine.

filo · 1 December 2022 05:02

Try to give a look at the kernel boot parameters mentioned in the post below.

If not helping, also testing other kernels might help. I’d start with the lts:

sudo pacman -Syu linux-lts linux-lts-headers

Finally you might search in the forum for your WiFi card or relevant driver.

filo · 1 December 2022 05:09

Damn edit button not working...
The first kernel parameter seems interesting because it stops the power management for the WiFi (which can cause speed slow down). The second parameter is about connecting to a network. In my opinion you could try also without it...

tbg · 1 December 2022 05:35

You should double check your bios version. I believe there is an update available.

https://www.dell.com/support/home/en-ca/drivers/driversdetails?driverid=r69t0&oscode=wt64a&productcode=xps-8940-desktop

Updating your bios is a very important step in resolving issues with your hardware.

Your wifi adapter is well known for having on again, off again issues in Linux. There are no shortage of threads dealing with that adapter.

As far as your Ethernet goes, it might be worth testing out the r8168-dkms driver. Switching drivers may improve your performance. Reboot after installing the new driver.

Good luck, and nice to see you back on the forum again.

mdoverl · 1 December 2022 06:52

I’ll do this first before moving on to @filo 's suggestion.

EDIT: I’ve never updated a BIOS with Linux running on a machine. Hopefully I figure it out.

Flashing a Dell BIOS in a Linux Only Environment

As Linux and Ubuntu distributions are becoming more popular on Dell systems, there are more situations where a Linux only environment is present.

UEFI Capsule updates

If your system is listed at LVFS: Device List, then it supports UEFI capsule updates and can be updated natively within the OS.

Ubuntu 16.04 and later natively notifies you of new BIOS updates. When an update is available, a notification is displayed to flash the update.

Note: Other Linux distributions may need to have the capsule flashing tools manually installed. Check with your distribution vendor for more information.

If your system or Operating System does not support UEFI capsule updates:

For newer systems (post-2015), refer to Section 2 below.

For older systems and releases of Linux/Ubuntu, the process to create a bootable USB BIOS update is referenced in [Section 3](Update the Dell BIOS in a Linux or Ubuntu environment | Dell US a USB Bootable Storage Device) and Section 4 below.

Luckily my device is listed in the LVFS Device List. So Now I need to find a Capsule Flashing Tool

EDIT: Scratch that. I’m going to a method listed below that, I’ll flash it with a USB.

mdoverl · 1 December 2022 23:20

Just updated the BIOS and still getting network lag.

Going to try r8168-dkms driver now.

mdoverl · 1 December 2022 23:28

Installed r8168-dkms and rebooted.

Still network lagging.

Going to start looking at the kernels now.

mdoverl · 1 December 2022 23:34

Tried to manually look at kernels via start menu, settings application launches put it's not bringing up screen where I can look at kernels. I know this was a feature in Manjaro. Not sure if it's not available in Garuda.

mdoverl · 2 December 2022 00:01

Changing the kernel to linux-zen solved the network issues.

The blinking issues in browsers is casued by some weird addon in vivaldi and falkon called FeedreaderObserve.

BluishHumility · 2 December 2022 00:37

Glad to hear it, although Zen is the kernel you started with. Do you mean the LTS kernel?

mdoverl · 2 December 2022 00:59

Ahh, I selected Zen. I didn’t realize I was on Zen already. I select LTS during the installation.

Edit: :Checks Notes: so I was already on Zen. What the hell actually fixed it then? Well I’ll take a happy accident over nothing.

mdoverl · 2 December 2022 02:54

Thank you both to @filo and @tbg

Both issues have been resolved.

mdoverl · 2 December 2022 03:26

It’s nice to see you also. Actually, seeing your name and many others that I remember from Manjaro and Endeavour was the main reason I came full time to Garuda. I remember I tried Garuda a few years ago but I was super intimidated by it back then and left. I actually left Linux after that because of some community drama elsewhere a couple years ago. I look forward to lurking on the forum and learning how to fish.
