I'm having problems with my internet connection with ethernet and wifi. Recently We have changed office and now We have internet connection that the only difference is the new is a Gigabit speed. With ethernet and wifi the connection is randomly disconnected, but applet of NetworkManager keep connected, but ping not working. This only happen when I am iddle by 1 or 2 minutes, then anything command that try uses internet fails.
ping google.cl ping: unknown host google.cl sudo ifconfig enp2s0 Link encap:Ethernet HWaddr 70:8b:cd:05:0a:3f inet addr:192.168.100.5 Bcast:192.168.100.255 Mask:255.255.255.0 inet6 addr: fe80::9bc3:d8f5:a9e9:899d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7258 errors:0 dropped:0 overruns:0 frame:0 TX packets:5997 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4229103 (4.2 MB) TX bytes:856374 (856.3 KB)
Trying using wifi has the same effect, then I think this is not a driver problem for r8169 ethernet. There is no log in syslog and I don't know
Some data about my system:
