Slow internet(just installed yesterday Manjaro KDE)

Hi everyone,

I have a slow internet the whole system is lagging even when i use the konsole.

▶ uname -ra
Linux dan-pc 5.4.18-1-MANJARO #1 SMP PREEMPT Thu Feb 6 11:41:30 UTC 2020 x86_64 GNU/Linux

Screenshot with speed test from Netflix

Can someone tell me the reason why this is so slow?


Can you try another kernel: e.g. 4.19.xx ?

I did install 4.19.102 but don't know how to enable it. Because in Kubuntu from where i come from that was not advised.

Do i have to edit grub default to enable it?

For others that may look for the info visit this link

You can use a different installed kernel by using the advanced options in Grub menu.

Yes, unfortunately still lagging even after moving to 4.19.102-1 kernel

Got 72 speed and latency of 18

In wired connections, I have auto-negotiation turned on

Can we test this with wireshark for TCP window scaling problem? Could that be the problem?

Do you have another OS (Win) to test your computer and the data transfer rate?

The first boots of a freshly installed Manjaro KDE system can be a bit slow sometimes, especially on systems with HDD. There is some fs initialization ongoing, depending on settings baloo file indexing could still be active, and maybe you missed to verify your entropy by not doing systemctl enable haveged. So, for my taste a bit premature decision to switch to Kubuntu right away. This cannot be deemed as solution, sorry.

You maybe right. I will come back because amd r9 390 my video card doesn't work with vulkan no matter what I do. It only works in Manjaro.

Thanks @Wollie for the tips, I will try them soon.

Very fast after using your suggestions @Wollie. But the internet is still lagging unfortunately.

To describe the felling is like this:

It waits for a couple of seconds before transfering packets. I don't know what is causing it.

Can you try to install an additional network card with an Intel or Realtek chip?
And test again?

Your firmware is pretty old (11/03/2015), have you checked if there is an update available?

Also, here is a thread with a similar problem, have a look and verify if the suggestions from almighty @tbg might be helpful in your case as well.

Thanks I will take a look in the thread. Also what is the best way to find manually the newest bios for my motherboard?(I am asking because i always used the program that came with the board and updated automatically from gygabyte server)


From the vendor's website, usually.

I don't know if the version from Gigabyte is newer then the one they had on their servers.
The newest I found is from 2016

Either way, your current one is F1, the first released BIOS for that board. Gigabyte is offering F2.
I have no experience updating via their utilities, but any method should give you a more recent version.

Edit: The update is LAN-related, no less.

I will try this one. Thanks

I did it using q-flash:

  • You need to have an usb with fat32 partititon
  • Download the bios, extract it and copy to usb stick,
  • Reboot
  • Then press end .
  • You will enter q-flash menu
  • Select the from file option
  • Select the file and hit yes

[dan@dan-pc ~]$ inxi -Fzxxx | grep F2

Thanks for the help everyone

I was wondering if in the meantime a new release of network manager has arrived for building because i couldn't see anything on their gitlab.

Also following an arch post

This timeout looks odd

Also maybe i should open a new thread with the specifics of this problems?

No, do not cross post.

Have you disabled IPv6.
