I've installed a new OS on my machine which is a pure Arch Linux. Everything works well, but I have difficulties to find out what is going on with my Ethernet.

On the same machine, I have PopOS working flawlessly.

The symptoms are the following:

  • With neovim I need to do :PlugUpdate8 to get the update through otherwise it is loosing connection (Like explains there: https://github.com/junegunn/vim-plug/issues/502)
  • Still with neovim, when tree-sitter try to downloads what it needs, it never works. I always have an error message telling me to check my Network.

While this look like only neovim. I realize that I was loosing the connection and could not access any sites.

At one point other device connected to the same Switch lost the connection too.

I remember having this issue the first time I install this computer. A BIOS update at the time fixed the issue.

I checked those informations:

lspci | grep -i net
05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
sudo dmesg |grep r8169

[ 8143.010760] r8169 0000:05:00.0 eno1: Link is Up - 1Gbps/Full - flow control off

Which looks ok...

Could someone helping to debug my issue?

After some bandwidth check and some debugging. I did not find anything...

Until I realize that the error on the browser relates to DNS. I am behind AdGuard installed on my local NAS.

Changing the D.N.S. to 1.1.1.1 solved the issue...

So, it is finally not Linux related. I will continue debugging my issue on AdGuard.
