Dropped again. Here are the results of ifconfig: rsteff@ENU-2:~$ sudo ifconfig [sudo] password for rsteff: enp0s31f6 Link encap:Ethernet HWaddr 70:8b:cd:7f:0c:56 inet6 addr: fe80::aff0:732b:5508:6fb5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6750853 errors:0 dropped:0 overruns:0 frame:0 TX packets:4152265 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:6321412070 (6.3 GB) TX bytes:867072229 (867.0 MB) Interrupt:16 Memory:f7100000-f7120000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:304784 errors:0 dropped:0 overruns:0 frame:0 TX packets:304784 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:30561735 (30.5 MB) TX bytes:30561735 (30.5 MB) From that I conclude that I don't have a dhcp lease. The lease is renewed by clicking on the Wired Connection 1 line in the drop down menu called Ethernet Network. rsteff@ENU-2:~$ sudo ifconfig enp0s31f6 Link encap:Ethernet HWaddr 70:8b:cd:7f:0c:56 inet addr:192.168.0.134 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::aff0:732b:5508:6fb5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6752256 errors:0 dropped:0 overruns:0 frame:0 TX packets:4153960 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:6321770679 (6.3 GB) TX bytes:867335636 (867.3 MB) Interrupt:16 Memory:f7100000-f7120000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:306131 errors:0 dropped:0 overruns:0 frame:0 TX packets:306131 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:30680298 (30.6 MB) TX bytes:30680298 (30.6 MB) Using the Google FOO: ubuntu MATE 16.04 loses dhcp lease I found this: https://superuser.com/questions/1087359/occasionally-losing-wired-lan-connection-on-ubuntu-16-04 I have to leave in a few minutes, but I'll pursue that further when I get back. Thanks for the pointer to dhcp lease. -- Regards, Dick Steffens _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
