The Wired Network option is not enabled

achu_ncl · 01-29-2009, 10:48 AM

Hello,

I am using the latest version of Ubuntu . When I select the network manager applet to connect my laptop to wired internet connection, I can't select the Wired Network option as it is disabled(I don't know why).
Would anyone be able to help me in telling how to activate the wired internet connection option on ubuntu?

Thank you very much for your time and help.

With the network manager open, click on the unlock button.

Enter your password and this will unlock the options.

What network card/chip? If you don't know, you can find it by running this command in a terminal:

lspci

It could be that the driver is not loaded. First we need to know what the card is and then find out what driver it needs. Then you can check to see if it is loaded.

Hi,

Thanks for suggestion but I couldn't find the unlock option in network manager. Can I have some more specific direction to achieve that thing.
Thanks again

Thank you,
When I type lspci, lot of cards(like USB installer, Ethernet....) etc are displayed. I am new to Linux, could you please tell me which one to look for?
I appreciate your help

Ethernet is what is used for a Wired Network.

if you have manually edited /etc/network/interfaces and made changes to your wired interface (such as assigning a static IP address), network-manager will just ignore the interface and not have any control over it. Network-Manager basically just greys out all the options for that interface so you can't view or change any settings for it.

click on system>administration>network
The box that open up will have the unlock option on the bottom.
