Ethernet connection with r8152 drops randomly

Hello to everyone,
I’m using Manjaro for about 6 months and I can say that it’s one of my favorite distro. Now I have a problem and I would like to know which is the cause.
Until now, my internet connection was through WiFi using a Wireless adapter. Some days ago I decided to buy a Ethernet/USB dongle (with chipset Realtek RTL8153) to improve the connection performance. The connection with the WiFi works well while the wired connection does not work: the connection deactivates itself or the speed becomes zero after a random period of time (may be after 1 minute, may be 10 minutes).

What I did:

  • I tested the connection with other distros (Pop OS, Ubuntu). The wired connection works properly without any issue.
  • I installed and selected the same Kernel (5.4) used with other distros, checking the driver version (it is r8152 v1.10.11). Nope.
  • I downgraded the NetworkManager selecting the same version running on Pop OS (v1.22.10, while the latest is the v1.26.2-1). Nope.
  • I tried to debug the log of the NetworkManager with journalctl but I did not find any error or problems.
  • I installed dhclient and configured the NetworkManager to use it. Nope.

In addition when the connection drops or deactivates the NetworkManager can not be restarted. The laptop hangs on the shutdown waiting for the NetworkManager service and I had to poweroff the computer with the power button.

Thank you for your support!

It seems to be difficult to get this device to work, see here a similar case:

You could try the dkms version from AUR by first disconnecting the device and then

sudo pacman -Syyu bc dkms git base-devel pamac-cli --needed
sudo pacman -S $(ls /boot | awk -F "-" '/^linux/ { print $1"-headers" }')
pamac build r8152-dkms

Blacklist the kernel module by

echo "blacklist r8152" | sudo tee /etc/modprobe.d/r8152-blacklist.conf

and run

sudo depmod -a

sudo mkinitcpio -P

and finally reboot.

Thank you Wollie. I followed the procedure for the dkms driver installation but now there are no available wired connections. The driver is now usb-network:

OK, let’s have a deeper look into your system. Please post output of:

uname -r
lsmod | sort
sudo rfkill list
lspci -knnvvv | grep -i net
hwinfo --netcard | grep -Ei "(speed|hotplug|model|status|cmd|file|detected|driver:)"
journalctl --no-pager -S "$(date +'%Y-%m-%d')" -u NetworkManager  | grep -i 'discon\|error\|seg\|fail\|broke\|warn\|change\|8152' 

Also, please check the other side of your network adapter (router etc.).

Here you go (note that now I’m using an external WiFi adapter (Ralink MT7601U Wireless Adapter) because the internal WiFi ( wlp2s0) does not work every time as well (the connection is not always successful but it is out of the scope of this thread):

Thank you so much

Are you using tlp? You could try to temporary stop and uninstall it by

sudo systemctl disable --now tlp
sudo systemctl mask tlp
sudo pacman -Rs tlp

This is only to test if your issue is linked to tlp. If yes, then you need to find the right tlp settings. I would not use the system completely without it. If it’s not helping reinstall tlp.

It could be an option to blacklist your device from tlp though. With lsusb you should be able to find your device ID.

Have you tried other kernels?

I never used tlp, is it enabled by default?
I have tested the 5.4, 5.6, and 5.8 kernel but the same problem occurs.

Now I have removed the dkms driver and renabled the default driver (r8152). Then I have disabled and removed tlp as you suggested.

I will try it out and I will update you. Thank you Wollie.

Hello Wollie,
I suppose that the problem was caused by TLP because now the connection is working correctly :slightly_smiling_face:

Thank for your help!
