Hi @all,
to increase the network speed on my vero4k i’ve bought the usb network adapter from csl that’s mentioned in many threads here.
Nowy network speed is lower than without the adapter, i used to have file transfers fromy pc to the vero with about 12MB/s, with the adapter the speed is 4- 7MB/s.
What am i doing wrong?
To get a better understanding of the problem you are experiencing we need more information from you. The best way to get this information is for you to upload logs that demonstrate your problem. You can learn more about how to submit a useful support request here.
Depending on the used skin you have to set the settings-level to standard or higher, in summary:
enable debug logging at settings->system->logging
reboot the OSMC device
reproduce the issue
upload the log set either using the Log Uploader method within the My OSMC menu in the GUI or the ssh method invoking command grab-logs -A
publish the provided URL from the log set upload, here
Thanks for your understanding. We hope that we can help you get up and running again shortly.
OSMC skin screenshot:
If you’re able to SSH to the device, what’s the output from running the command lsmod?
here you are:

Try this:
echo "blacklist cdc_ether" | sudo tee /etc/modprobe.d/blacklist-cdc_ether.conf
then reboot.
hmmm, now it’s even worse, under 5MB/s… 
Please show the output from lsmod again.
thanks for your patience!

I’m just about out of time for today.
For now, remove the blacklist file
sudo rm /etc/modprobe.d/blacklist-cdc_ether.conf
then reboot. During the reboot process, pull out the ethernet adapter and only insert it once the Vero4K has fully restarted. See if it makes any difference.
sadly it didn’t change anything… 
Can you try another adapter?
Might just be a limitation of the adapter.
the adapter should be ok, it’s the recommended csl/realtek adapter that people in this forum recommend.
i don’t have another one.
Have you tried a different Ethernet cable? It could just be a marginal cable.
Hi,
today i’ve changed the cable, but the results are the same.
I really don’t know what to do now, because i’ve bought the adapter to migrate my HDDs to my new PC and stream my media over net. Frustrating…
Perhaps the adapter is faulty. Can you swap it with the seller?
Could you show us some iperf3 figures for the unmodified configuration?
Since I tried to blacklist cdc_ether, which didn’t seem to help, I suppose we should also try to blacklist the r8152 driver.
echo "blacklist r8152" | sudo tee /etc/modprobe.d/blacklist-r8152.conf
then reboot.
Ok, thanks for your help!
I totaly forgot, that i have a switch in my network. I think it’s important for you to know!?
It’s a GS108Ev3 - 8-Port Gigabit ProSAFE Plus Switch from netgear and to be honest, i did install it and didn’t do any settings in it (because i really don’t know what settings to make). I think that this could be the problem?
Well first step would be to check the negotiation with ethtool (sudo apt-get install ethtool).
Share the output here.
