Two ways could re-establish the wire connection:
A. Re-enable the networking
1. click the "Enable Networking" of the network manager indicator on the upper-right coner of the desktop to disable the networking
2. click the "Enable Networking" again right after the networking is disabled.
3. the system will establish the wire connection automatically if the wire has been plugged in the machine.
B. Re-insert the alx kernel module
1. command "lsmod | grep alx" to make sure the alx is in use and it trys to operate AR8161
2. command "sudo modprobe -r alx"
3. make sure the connection is lost
4. command "sudo modprobe alx"
5. the system will establish the wire connection automatically if the wire has been plugged in the machine.
