Hello there,
so i have a laptop with Atheros AR8151 Gigabit ethernet adapter, it runs fine with OpenElec 6.0.3 and Windows 7 at 1Gbits (i can transfer files over the network with OpenElec at aroung 70-80MB/s), however, with Kodibuntu the link runs at 100mbps. although ethtool eth0 output shows 1000baseT is supported. i can only transfer at about 10MB/s.
i've already done the following to make sure my system is up to date:
Code:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install update-manager-core
sudo do-release-upgrade
what is the solution so the card works at 1Gbps instead of 100mbps?
thanks!
if ethtool shows 1000baseT is it should be ok.
How do you test transfer speed?

thanks for the reply,
sorry i meant to say 1000baseT is supported, but link speed is 100Mb/s
please see below output of:
Code:

i test using ftp download of a 5GB mkv file,
sudo ethtool -s eth0 autoneg off
sudo ethtool -s eth0 speed 1000 duplex full
Better check your cable :-) it most of the time has a reason to only sync with 100 Mbit.

thanks, that worked, although autoneg still shown on. i also had to run the commands while the link is down (used a usb ethernet adapter for this), as running it through SSH to eth0 did nothing.
now link speed is 1000 and i can transfer over wireless AC at 30MB/S, so that confirms it works fine.
here is the ouput of
after the commands above:

although it works fine in OpenElec, before i start this thread, i tried the exact same setup using a usb gigabit realtek ethernet adapter (same cables and config connected to same laptop, only unplugged LAN cable from built in Atheros adapter and connected to realtek usb adapter, link speed is 1000Mb/S without doing any changes or entering any commands.
thanks wsnipex and fritsch, much appreciated.
