Very new to linux. I have built a server that I have being hosted about an hour away from me. I set it up with Ubuntu server 22.04 lts and it was able to ssh in locally and remotely just fine. Only issue I was having was the link speed was only getting around 940 mb even though the MB i'm using (Gigabyte MZ33-AR0) has native dual 10gig nic's.
SO after a semester of linux (googling for a few hours) I figured out (I think) it was the link speed settings
I ran the following code (of course without backing up because why would I)
sudo ethtool -s enp9s0 speed 10000 duplex full autoneg onhit enter and now I cant ssh back into it or even ping it. I had the host pull the ethernet out and place it back in and also restart the server itself. Other thing I did notice when running another ethtool command was it wasnt showing all available link speed capabilities.
after some more google university I think my only other option is to try restarting the network manager.
So question is am I on the right path or is there something else I can try to get my network adapter settings back to default.
I have mentioned here everything I did before making the change using ethtool
Note: I did give it a static IP in the ISP gateway.
