I am using di 624 c3 wireless router and able to go online wirelessly in windows xp. However, I use use Ubuntu 9.04 and the laptop only able to go online when it is wired to the wireless router. I am able to go to the http://192.168.0.1/ setup page. But when unplug the cable from the laptop, wicd manager was unable to connect to go online.

Do you know how to fix it?

Lucy

What is your wireless network card?
Does it appear in network manager?
If not please post the following commands:

The driver of your network card is installed, so it's probably a configuration issue. What did you do to try to setup your connection?
Did you specify WEP, WAP, or did you input a password?

Hello,

Did you try the network manager that comes with Ubuntu? If so, did it show up any wireless network?

If not, try in a terminal this:
and post the output here.

Kind regards,

Eric

Sorry: Just noticed in your title that you used wicd. You could try from the command line though, put the output of the command I posted here. That way we can determine if it's a wicd problem or not.

I have chosen WPA-TKIP PSK and entered a password in the setup page http://support.dlink.com/emulators/d..._wireless.html

iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

Thanks

Please, post outpost of "iwlist eth1 scan" (from root terminal).

Ok,

Now, execute the following commands:
It will give you an output of all available wireless networks encountered. Write down the ESSID and address of yours.

Next execute the following:
The key part expects hexadecimal so if you only know the ASCII you change the command to this
If this works your wireless should be up and the fault lies in my opinion with wicd. If the fault is with wicd, just uninstall it and re-install to see if it fixes it.

Kind regards,

Eric

I'm sorry I didn't mention that but did you run those commands in a root terminal? If not you'll have to put 'sudo' in front of everyone of them.

And the "Your_key" part is where you put in your passwordkey you have to provide in order to connect to the wireless network.
