Ethernet occasionaly not working

Issues & Assistance Networking Support
1

I recently moved my computer to a different room and understandably have been connecting it to a different Ethernet port then before. This Ethernet port is very spotty, sometimes doesn't work entirely or flickers on and on. I connected a windows machine to the same ethernet port and had no issues. On the ethernet in the room I used to be in I never had even a slight performance drop. The ethernet I am attempting to use is going through a ZyXEL network switch if that makes any difference

I appreciate any and all help!
Thank you in advance!

What matters is.... We need a garuda-inxi report so someone can potentially help you. That will provide us details on what Ethernet NIC you actually have as a starting point.

I hope this helps!

You MIGHT be a good candidate to try the r8168 driver (package r8168), or the r8168-dkms (from chaotic-aur), which it what I use myself.

[SOLVED] Problem with Realtek 8111/8168/8411 | No internet | r8169 / Kernel & Hardware / Arch Linux Forums is one reference to it, including the manual blacklist if need-be, but doesn't include the r8168-dkms which works with more kernels, including one you seem to be using as well, linux-zen, so, yes.

pacman -S r8168-dkms might solve your problem.

90% of Ethernet performance problems are related to cabling.

Windows will often be problem free, while Linux can have issues with the same network cabling. I would highly suggest purchasing some cat 6e or cat 7e cabling to make sure cabling is not part of the issue.

so it would be the cableing from the router to the network switch if I understand you correctly?

I installed the r8168-dkms driver and the issue persisted

Thank you for the help though!
