Ubuntu 16.04 and connect my machine alongside other machines by using a
Hub to a modem to use Internet. Today I encounter with a problem:
Other machine can connect to the Internet; but I cannot access web (
Server Not Found error on browser and
ping: unknown host google.com as result of
$ ping google.com in terminal), unless after doing disconnecting/re-connecting network cable. But this way only works for a few seconds up to 2 minutes. Although my Android device can connect to the web continuously without any problem through
Also I connected my machine directly to the modem and even changed the network (Ethernet) cable. But result was the same.
What causes this problem and how I can solve that?
I can open
192.168.1.1 from my machine but cannot login; although it is possible to do that from my other machines.
nameserver 127.0.1.1(but that file is a link to
- the result of
$ nmcli device show $ethernet | grep DNSis:
$ dig 126.96.36.199 google.comand
$ dig 188.8.131.52 google.comwork when I can access web ; but when problem occurs, I get "
;; connection timed out; no servers could be reached"
It seems that my machine automatically changes used connection from
Internet (which is used to access web) to
virbr0 which causes problem:
$ ip route show when I can access & cannot access the web:
