Ubuntu

No network Connection. Replaced a switch.

Asked by Gunnar Tryggvason

I reconnected from 1 GB switch to 100mb switch. All is on auto, i.e. receiving IP automatically etc. I am able to get IP-nr, from the router on a windows-xp laptop. This is a wired connection and I tried to put in a manual address, but the computer is unreachable. The computer is running 9.04. How do I unblock the connection?

Try this one:

Change your static address to dynamic address option then open your terminal and input the following command below:

Release IP:

sudo dhclient -r

and Renew your IP from your DHCP server with:

sudo dhclient

Lastly, try pinging your gateway IP address:

ping IP_of_your_Gateway

HTH.

Thanks. If I ping the gateway, or any other computer, result is "unreachable". There is a green light on the onboard netcard and also on the switch. When sending Sudo dhclient -r I get following reply .: sending on Socket / fallback. If I input manually an IP-address I can Ping that address but I cant see the gateway or any other computer. Maybe my netcard is broken?. The wiring is ok.

Can you help with this problem?
