qtplasmac (Operation Error: hm2/hm2_7i76e.0:) in middle of cut

I replaced the thermal paste on the cpu and I am still getting this error at lower temperatures.
 
here is a ping test
 

My problem is not being caused by low latency due to overheating here is the temperature at the time of the error. Mach 3 would never do this using this same PC I cant get a full cut and it is very frustrating. please tell me what PCs you guys are using to not have these problems please let me know where to find instructions on how to start a cut in the middle of the file so at least cut recovery is simpler. 

What does

lspci  | grep -i eth

report?
 

 

lspci  | grep -i eth

The character after lspci is a vertical bar
( usually shift \ ), not an 'L'

 

OK that's Intel so needs IRQ coalescing disabled

Before messing with the network setup its possible
to do this from the command line:

sudo ethtool -C [device] rx-usecs 0

where [device] is the name of the Ethernet device connected
to the Mesa card (usually something like eno1 or enp2s5 or similar)

You can determine this name with the command:

ip a

 

I got a command not found
 

Try

locate ethtool

to see if its installed

if it is found, you may need to give the complete path

if it's not installed you will need to install ethtool

sudo apt-get install ethtool
