Starting last month the PC Ethernet connection is sometimes not made at bootup or is occasionally lost. When this happens the only way I have found 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? |
