Hello, i'm realy new in all linux concern, and i dont really have to many problems with ubuntu. But the other day i strted using CDLinux, which is really amazing despite the fact i can't get it connect to the wireless, i know the pass of the signal, i'm not trying to hack it, is a WPA, and i don't really know what i'm doing wrong. Thanks gave behind.

CDLinux ? did you mean live CD ?

Regardless of distro, it will help others to assist you if we know

• Which application you are using to connect
• Model of wireless interface
• Actions you have taken so far which haven't worked

If you need any help in obtaining this information, please ask in reply. Thanks.

No no, I mean "CDLinux" it's a 214mb version, is very good, but i heve this little problem with the wifi, thanks

to gold_leaf

I am using Wicd Network Manager
The signal is at 74%, is WPA, it say's Channel 11 which i dont know what means. In the poperties of the signal is on "Use encryption" and "Use these settings for all networks sharing this essid"
Is selected WPA 1/2 (Passphrase), and the key is o.k.
In preferences, general settings, the wireless interface is wlan0, and the wired interfece says eth0, i don't know if this last one is important or not.
In preferences, external programs, DHCP Client is in automatic, the route table flushing is in automatic, and the graphical sudo application also automatic.
In preferences, advanced settings, WPA Suplicant, Drive is "wext", Backend is "external", and Debugging and Wireless Interface isn't on.

These are the options i have been switching on and off, up and down, and so.
My machine is an Acer Extensa 5230, i'm running CDLinux from a USB-flashdrive, and with ubuntu the connection works well.

Thanks again.

Moved: This thread is more suitable in Linux-General and has been moved accordingly to help your thread/question get the exposure it deserves.

The channel shouldn't make a difference since you say the connection works on Ubuntu, proving that there isn't too much interference. What I know from experience using wicd is that it's important to select the currect subcategory for WPA, you should see options for preshared key, hex and so forth - have you tried these?

It's not, and assuming that you only have one wireless interface it should be wlan0. Just to make sure, you can do

in a terminal just to make sure, it will list all your network devices and settings. Depending on your $PATH and permissions, you might need to do

or even

IIRC wicd has the option to let it choose automatically which backend, driver and so forth to use. I'd let it. WPA Supplicant and driver are probably right, but choosing backend as "external" implies that there is one. I'm sorry I don't use wicd right now, or I'd check, but that sounds suspicious to me. Perhaps someone else will know better or at least have wicd to hand. Debugging should probably be off, but having "Wireless Interface isn't on" doesn't sound any kind of right. Could you clarify? I don't remember wicd well enough to understand what you mean here.

All of the above assumes that the distro you're using supports your wireless card out of the box. It might not. You do mention that you're getting a signal, though, which implies that it does. Just to make super sure, and I'm assuming you're using an onboard wireless card rather than a usb dongle with this, the command:

should hopefully tell you the model of card you're using, and which kernel modules have been loaded to make it work. If you continue having difficulties you can post that information here to help others help you. Best of luck.
