Hi there.
I can't access Internet when my centos7 PC linking on a router,but other windows PC on this same router can.Whatever I use auto DHCP or configure the IP address manually.
In this condition,I can ping other PC on the router and I can configure the router on the centos PC,but I cannot access Internet(can't use google).
When the centos PC directly links to adsl modon by UTP,I can access Internet instead.
I'm really a new hand，and I've been confused a long time,can anybody help me there?Grateful!

Re: I cannot access Internet with router
Experiment (DNS check):
From a terminal window
ping -c3 google.com
If it works, then skip the rest - your DNS is working and something else is amiss.if that bombed however, then
ping -c3 8.8.8.8
If that works, (but pinging a 'name' fails) then you have a DNS (name resolution) issue. Try using 8.8.8.8 and 8.8.8.4 as your DNS servers.in your network card config.

thanks for all.
The problem has been solved.It's not centos's fault but my computer.I don't know where the prblem is,but when I restart the PC,and ues only one of the Ethernet port,the router does work so I can access Internet.
