Starting last month the PC Ethernet connection is sometimes not made
atbootup or is occasionally lost. When this happens the only way I
havefound to re-establish the connection is to turn the TP-Link AC1750
router off and on again.
The system is Debian Stretch.
The connection was just dropped and I recorded the attached last 60
lines of dmesg and syslog
Can anyone tell me why this happens or point me to references I must
study to learn how to fix this?
