I am using a D-Link GLB-502T router at my place which provides me with a cable with an RJ-45 plug. I put this into a D-Link DIR-605L Wifi router to access internet wirelessly.

All is fine till I am using Windows 7. However, the problem starts when I switch to Linux. I am unable to connect to the Internet when I am working with Linux. This does not work irrespective of whether I am trying to connect wirelessly or via a cable. However, I am able to connect to other systems on the LAN under my wifi router.

Can anyone suggest what is wrong with my system?

P.S: I am using Linux Mint.

  • Can you ping the ip of your router? What is the output of the commands of "ip addr ls" and "ip route ls"?

  • Here is the cause: "eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP>". Your ethernet connection is down. You are accessing your LAN through your wifi connection. Turn your lan down, and make a reconnect with your ethernet connection, what happens?

Successful local(same LAN under AP) communication means there is no problem on wired/wireless connection it self. So I can guess wrong configuration of GW or DNS on linux box.

If your local LAN use DHCP, check GW and DNS was auto configured or manual, and has right value.

anyway I think this Q is off topic.
