Low bandwith on ethernet

Hey, I'm aref. I'm new to Arch and Garuda. Recently I've installed Garuda KDE Dragonized. But my problem is my internet bandwidth is super slow while it is ultra fast on my Galaxy A12 device. How can I make my internet super fast on Garuda KDE Dragonized?

My PC specs:
Intel Pentium G3250
1TB HDD
DDR3 8GB RAM

Hi there, welcome to the forum.
Could you please provide your garuda-inxi, as per new topic template?

May I cannot do that.

Why? There's nothing confidential in there.
I've seen so many topics where the simple garuda-inxi provided important info.
It is a rule... From the template:

Refusing to post the output of the required "garuda-inxi" on a help request will likely result in you not receiving any help from the Garuda team. A failure to provide your system specs may also result in your thread being closed without notice, (as without this information providing assistance is often next to impossible)

Try to renegotiate and see if that fixes it.

ethtool -r enp0s25

If not, try to set it explicitly.

sudo ethtool -s enp0s25 speed 1000 duplex full autoneg on

You can probably do this pretty easily from the GUI as well.

For a permanent solution, you will need to determine why auto-negotiation is not working correctly. You may find this thread informative: [Solved] - How to permanently set the speed of my ethernet device? / Networking, Server, and Protection / Arch Linux Forums

In addition to the above, if the speed is really bad, don't forget to try a different cable (this is a source of troubles more than you could expect).
Finally, you could try switching to the r8168-dkms driver, installing the relevant package.

The above great suggestions cover the most common fixes of slow Ethernet. However, there are a few fixes that are often overlooked that I might add:

Reboot your router.

Try a different port on the router.

Most speed issues using Ethernet have a simple solution. The most basic is cabling (as already mentioned). Most people discount cabling as a cause because their speeds are fine using Windows. This logic is faulty, as Linux and Windows are very different. Linux can be far more finicky than Windows when it comes to cabling. Be sure to test out at least a cat6e grade of cabling to remove any doubt that cabling is an issue.

Also be sure your router's firmware and your bios are both up to date. Another solution that may help when all else fails is resetting your router to the factory default. This can be made painless if you save a backup of your router's customised config before resetting your router to default. If resetting your router does not improve performance you can simply restore your old customized config from the backup you made.

If none of these work, then occasionally changing from using dhcp to a fixed IP address (and vice versa) can help.

Good luck tracking down the cause, and welcome to the forum.

find-the-command: "enp2s0" is not found locally, searching in repositories...
find-the-command: command not found: "enp2s0"

What is this?

In what context?

Please post the entire input and output.

It looks like an incorrectly typed command.

This means you typed a command where enp2s0 was taken as the command, not a value or argument. If I had to guess, I would say you just entered what I quoted out of your inxi as a command.

That's not a command, that is output copied from your garuda-inxi.

Now that I think of it, there was a similar bug a while back that could be related to your issue. Switching to the LTS kernel helped in that situation. I think that bug was resolved a while back, but it still couldn't hurt to test both the LTS and mainline kernels to see if they might improve things for you.

In the future, when requested to run terminal commands, please always post the command input, and command outputs. This is essential when trying to diagnose issues remotely.

Which are you using, enp2s0 or enp2sO?
