THC problem

Thanks I have figured out how to make the changes in grub but not how to save it. I did see the options at the bottom, and thinking about it I was not having the complete keystrokes to do the write, Adding the ctrl key was what I was missing.  When I tried a similar route to windows it get a denied message.  I assume when I do the Ctrl^X it will then ask to replace the grub file with the changed one.
 
 

As Aciera suggested, you must use "sudo" when launching the
editor to edit system files:

$ sudo nano /etc/default/grub
 

Ok changed made to grub, did not help the latency error problem. I still get it randomly

Can you run this script to check your setup?

 

Download
chmod +x checkmask.txt
./checkmask.txt ethernet_device_name

ethernet_device_name will be something like eno1 or enp0s25
You can get a list with the command
ip a
 

Well I am dumb and a stick, I got the ip a and attached it here.
 
But had no luck getting the other info you want,  I am not a linux person so you will need to write exactly which the commands are needed for me to supply the info to you.
I tried to use the terminal but no luck,  I did do file searches but could not find that file (checkmask.txt). 
 
 

Case is important in unix/linux commands
(CHMOD is not the same as chmod)

chmod +x checkmask.txt
 
./checkmask.txt eth0
