Stuck on 100 Mb Ethernet

long_b

Hi all,

Not sure what I did but my Linux Mint install is stuck on 100Mb speed.
It's a HP Microserver N54L, I've seen it do 200 Mb+ before.

Plugging the cable into a Windows laptop instantly gives 250Mb+ speed.

I've messed around with ethtool but have only managed to break the settings altogether and had to revert to wifi.



Any suggestions for what I should try ?

Output from ethtool eth0 below

Whatever you're plugged in to is only advertising up to 100Mb.
Have you changed anything else including the cable ?

Thanks very much!
I plugged the cable and gave the network socket a good blast of Compressed air.
Back up to 200 Mb now
