problem with usb wifi adaptor: access point not-associated
 
hello everybody!

I'm trying to use a wireless adapter on ubuntu;
network manager seems not recognize it, but if I execute

iwconfig

a wlan0 is shown.

the problem is that it shows the name of my essid, but at access point field it says : not associated


what I can do?

I'm very new using ubuntu, so feel free to treat me like an idiot :)

Hi,

A few questions to clear things up:

1 - What are the make and model of the wireless adapter (to find this try the command "sudo lspci")?

2 - What is the output of the terminal command "sudo iwlist scan"?

3 - If you right click on Network Manager, is wireless enabled or disabled?

Also, you may want to look in the file /var/log/daemon.log for anything related to Network Manager. Maybe try "sudo grep -i networkmanager /var/log/daemon.log".

Feel free to ask me anything you like, I know what it's like taking up a new OS!

thank you very much!!

to answer your questions:

1) the adapter is a dlink dwl-g122, and is a usb one;anyway the command lsusb says: ID 07d1:3c03 D-link system
2) sudo iwlist scan gives output, for wlan0 : Address : 00:19:5B:98:01:06
ESSID : 'name of my connection'
mode : Master
frequency: 2.437 Ghz
encryption key : on
extra tsf= 00000033823781a5
3)if I right click on network manager it just says "enable networking" (I think is network magic 0.6 version)
4)the output at the command you suggest is attached in this post

thank you again!!

Hi afo3,

as far as I understand the logfile, you'll have at first to configure networkmanager to use your wireless network.

Which encryption are you using?

Hi, and thanks for the info.

First of all, is Enable Networking checked? It seems like your wireless device is working fine, but that your network manager app isn't picking your wireless interface up. I've not used anything called Network Magic before. I take it you installed it instead of the standard Network Manager? If not, then what's the distribution running on, as it's not the standard Ubuntu application?

I just made a mistake! I'm using network manager..and yes, enable networking is enabled!!

Markus

how can I control my encryption?anyway if I've understood what are you asking, it is WEP.

markush 12-20-2010 06:04 AM

Well, I don't have good experiences with all those networkmanager tools. But all of these tools should be able to handle WEP encryption.
Is there any field in this networkmanager where you can insert the key for your network?

no there isn't because networkmanager doesn't recognize the usb adapter..

Hi,

your text from post #3
Code:

2) sudo iwlist scan gives output, for wlan0 : Address : 00:19:5B:98:01:06
ESSID : 'name of my connection'
mode : Master
frequency: 2.437 Ghz
encryption key : on
extra tsf= 00000033823781a5

tells me that your wireless-adapter is working.
So if networkmanager isn't working correctly, uninstall it and take wicd (as an example).

ok, I uninstalled network manager..I found wicd at this url:

http://sourceforge.net/projects/wicd/files/wicd-stable/

which version you suggest? take in count that I'm using an old version of ubuntu (6.06)...
once downloaded, what command I have to execute to install it?

markush 12-20-2010 07:35 AM

Well, such an antique version of Ubuntu.... maybe that's the main problem.

Did you ever try to update Ubuntu? I'd strongly recommend to do so! I'd guess with a newer/recent distribution your problems with the wireless Network are solved instantly.

In order to help you further, please provide more information about your hardware (processor, Ram, diskspace).

I can't update because I'm running on an old machine that not support newest versions.
processor pentium III
ram 320 mb
disk 120 gb

at the moment I've downloaded wicd 1.7.0
reding install file it says to run :
Code:

sudo python setup.py install
I didi it, and then I reboot.
How can I use wicd now?

maybe not Ubuntu but a smaller but more recent distro than Ubuntu 6.06. Look at this: http://puppylinux.org/main/Overview%...%20Started.htm

if wicd is installed, there should be an icon anywhere in the gui. On my system (kde) on the right hand side near the bottom. There you may click (righthand button) and look what it says.
There are also configurationfiles in the /etc directory, please read the manpage
Code:

man wicd
