Comment # 2 on bug 1101244 from Mark Stutter

Hello David,

I think the problem is indeed that the card is recognized as a 100mbit card.
The output of ethtool enp0s25 says it only has a speed of 100Mb/s:

For some reason after a recent kernel update I now get speed of around 3MB/s
wich should be close to the 100Mbit/s, right?
Can you compare the output of the command on your system?
