Hey there,
first of all I’m very new to Linux so my knowledge is very little and my english isn’t the best, so I hope you can excuse some mistakes I eventually make.
I just bought the new Asrock DeskMini A300 which has a RTL8111H installed and I’m using it with Tumbleweed.
After setting up Samba I wanted to copy some files from my Windows 7 PC to the DeskMini but the network speed was very slow. I made a direct connection with a crossover cable, both sides sync to 1000Mbit/s and I even get ~100MB/s at the beginning but then the speed drops down to ~30-50MB/s. And this was tested with one large file.
After some research I now know that the RTL8111H doesn’t work very well on Linux and sudo ethtool -i enp51s0 told me the loaded driver was r8169 which comes with the main kernel.
Then I searched for a better driver and I found this page: https://software.opensuse.org/package/r8168-kmp-default
It tells me, that the r8168 also applys to the RTL8111H. So I did the 1-Click-Installation of the Sauerland package and when I now do sudo ethtool -i enp51s0 it returns:
driver: r8168
version: 8.046.00-NAPI
firmware-version:
expansion-rom-version:
bus-info: 0000:33:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no
So it has loaded the new driver but the speeds are the same.
[FONT=tahoma]sudo ethtool enp51s0 returns the following:

Am I doing something wrong? Am I missing something? Would be really nice if someone could help me to get the gigabit network working.
An old-school fix that sometimes works is to turn off auto-negotiation and set full duplex for whatever speed you want manually.
Of course,
You have to have a direct connection or through devices that support the speed you want, any slow devices between source and target like routers and switches will restrict speeds.
so today i tried at first turning off auto-negotiation and set the speed manually to 1000Mbit/s.
So if you look at this screenshot i made: https://abload.de/img/network1w9kyn.jpg you can see my network speed with auto-negotiation “on” on the left side (don’t mind the time passed, I canceled the job) and with auto-negotiation “off” on the right side. Looks pretty good at the first few second but then the speed drops again.
Then I changed auto-neg back to “on”, deinstalled the old driver changed the repo, installed the new ones. Median speed was a bit better (~70MB/s). As you can see in the next screenshot the traffic looks like a hacksaw: https://abload.de/img/network2sekti.jpg
Then I turned auto-neg back to off and set my speed manually to 1000Mbit/s again. And as you can see in this last screenshot I made (https://abload.de/img/network3vnj2o.jpg) it looks a bit better but somethings still not quite right because of this speed drops.
Yesterday I had my DeskMini connected to my router with a different cable and it didn’t change anything. So today I connected it directly to my PC again.

today i did some more testing. I downloaded a larger file of 4,4GB to test with. Then I remembered that I got a NVME SSD and that I could test the bandwitdh on this one instead of the HDDs. It looked very stable. Then I copied that file on a HDD and got 2 drops. Then I did this again and both copy jobs looked very well.
I also did a screenshot of my network monitor: https://abload.de/img/network4cjjut.jpg
I then copied some more but smaller files and it looked much better copying to the SSD than to the HDD. So I guess from now on it’s either the S-ATA interface or even the HDDs that are bottlenecking.
So I’m going to stick with the home:Sauerland:hardware repository and auto-negotiation turned off.
