Problem in connecting Wireless Internet in Ubuntu!!


Hey guys,
I was trying to configure wireless network on my ubuntu machine but could not do it. I am possibly stuck as I don't know much about configuring things on linux platforms.

Any help on it will be highly appreciated.

thanks in advance.

What did you try? What error messages did you get? What type of wireless card? USB, PCMCIA, internal? What version of ubuntu? If you want help, you need to bring something to the table: information.

@ brucehinrichs,
I have windows 7 also installed on my machine and wireless internet works perfectly fine on it.The wireless card is inbuilt.While the wireless icon on the top taskbar on Ubuntu always says "Disconnected-working offline",although the internet works perfectly fine with the wired networks(eth0).

I also tried the "/sbin/ifconfig" which gave me some description about the eth0 and "lo" about which I have no idea.
What I feel is that some drivers are missing 'cause otherwise the net won't connect even on the windows platform(the wireless card is present inbuilt...).
If that is the case or any other thing please let me know as its pretty urgent for me to start things up.

Thanking again.

You are still not giving much information. If you have windows installed, you could check the hardware configuration and give the make and model of the wireless chip. This will help finding the right driver for Ubuntu. It is possible, if you are using new Lucid, that drivers are already included. You just need to configure it properly.
You should also do:

lspci -vv on Ubuntu and paste the output. Also iwconfig and paste the output here.
Can you left click on network icon in Ubuntu and see if you see any wireless network list?

You sure are missing something. The drivers are loaded and wireless card has been detected. And you can see that from the iwconfig.
Can you right click on the network and edit connections and see what you get. I do not have wireless on the current desktop. Will try to get hands on some and let you know.

Connecting to wireless network is quite easy. Just left click on the network icon and if the card is properly configured, and if it can find any wireless networks around, you will get the list of the networks. Click one you want to connect to and bingo you are done. If its a secured one, you need passphrase for it.
But the one I am testing on is Dell Vostro 1014 with Atheros chip and is working in Live Mode and not installed. And testing with Ubuntu 10.04 LTS Lucid.
