Comment 61 for bug 2031537

after around 68 hours without network problem
it happened again

there was some network issue on other devices at the moment where it resolved automatically but not on my ubuntu pc I tested the cable on other pc and it worked with no issue but I had to restart my pc

I do not know if there is a way to restart just the part managing the network may be make a script restarting it if a problem detected

sudo dmesg
