Hello ak_k80

The response to the first command is exactly as I would expect.

The latter is a bit of a puzzle!

First thing to appreciate is that there are two ways of controlling wireless in Fedora, and they both conflict with each other.

I think the first thing to try is to make sure that isn't happening.

I assume you are running Gnome as your desktop and that you have a networking icon in the notification area right hand end of the top toolbar?

If not stop right there and post back.

If you have, go to the System Menu - Administration - Network. In the applet that appears you should have on the "Device" tab an entry for wlan0.

Highlight it and click "Edit".

In the new screen make sure "Activate device when computer starts" is not marked. If there is an entry for "Controlled by NetworkManager" make sure that is marked. Save the changes, restart and try the iwlist command again.

Don't forget the su part first or it won't work.

Post back the results.

Hello ak_k80

I've never come across this error message before:

Code:
Response: wlan0 Failed to read scan data : Resource temporarily unavailable
So I'm going to struggle to offer you much more help.

However I note in an earlier post you said that NetworkManager tried to connect to a network but just went round in circles. Is that still the case?

If it is, is there any chance you could turn off encryption on your wireless setup and see if it connects then?

Hello ak_k80

I've been re-reading the posts in this thread and I notice that in post #11 you say:

Quote:
i even tried to install wireless driver of intel for linux as mentioned in the above post,but i am toooo new to understand kernel and all
Does that mean that you did the following commands from post #8?

Quote:
% iwconfig wlan0 channel <channel>
% iwconfig wlan0 key <key>
% iwconfig wlan0 essid <name>
% iwconfig wlan0 ap <mac>
If you did take a look in the file /etc/sysconfig/networking/devices/ifcfg.wlan0 and see if the information you substituted in those commands is in there.

In fact, if you paste back what is in yours, I'll comapre it with mine.

Or did you download this file:

Code:
iwlwifi-1.0.0-1.tgz
from the intel site and try to install that?

Hello ak_k80

Actually, I asked you to look in the file /etc/sysconfig/networking/devices/ifcfg.wlan0. That doesn't mean trying to run it as a command, I meant opening that file in a text editor and seeing what is in there. Do not alter anything at random either.

As to the driver, you do not need to install one.

In fedora 8 all that is needed to make a 3945 card work is already in place when you install the operating system.

What I am trying to find out is just what extra steps you have taken that would stop the already installed driver working.

Hello ak_k80

Nothing there to give any clues I'm afraid.

When you said in post #12

Quote:
n N/w manager,wen i goto "CONNECT TO OTHER WIRELESS N/w" and type in the SSID along wid the key....it tries to connect but it again and again returns a window in which it asks the details abt the key...
did you have any existing wireless networks listed there to select from or were you still not seeing wireless networks then?

Really you should not need to be typing in these commands:

Quote:
[root@localhost ~]# iwconfig wlan0 channel 11
[root@localhost ~]# iwconfig wlan0 key
Error for wireless request "Set Encode" (8B2A) :
too few arguments.
[root@localhost ~]# iwconfig wlan0 key ankit
[root@localhost ~]# iwconfig wlan0 essid Ankit Khare
iwconfig: unknown command "Khare"
[root@localhost ~]# iwconfig wlan0 essid "Ankit Khare"
[root@localhost ~]# iwconfig wlan0 ap 00:18E:B7:5E:73
[root@localhost ~]# ifconfig up
up: error fetching interface information: Device not found
[root@localhost ~]# iwconfig up
You should be letting NetworkManager do it all.

One thing that does leap out though is that you have a space in your essid, hence the output:

Quote:
iwconfig: unknown command "Khare"
Does your access point work in Windows? I really don't think spaces are a legal character in ssid's or if they are then the iwconfig command doesn't recognise them without 'escaping' them.

If you didn't see any networks in NetworkManager earlier, is it possible that you are hiding your ssid? That won't work with the Fedora NetworkManager either.

I really do have to suggest now that you go for a reinstall of the whole operating system so that we are certain that everything is back to clean install. I'm fast running out of ideas and a 3945 should just work.

hello bbfuller,
REgarding post 12...
since the day i hv installed fedora,i hv been noticing n/w manager appearing on the top right corner(Gnome)....wen i used to RIGHT click on it,there were 2 options Enable wireless and Enable wired n/w....both were marked...
wen i used to left click on it,then tho option "wireless n/w in range"(i dont remember exact words as i m in windows rite nw) was NEVER HIGHLITED,only one option was highlited,CONNECT TO ANOTHER WIRELESS N/w...on clicking on that,it used to ask me the n/w name,and key if there was any....thats y,i tried every possibilities with it....wen i used to fill in the detail and press ENTER, on the place of n/w manager icon,there were 2 small balls, 1 being green and other being red appeared...and then after smtime i finally get msg "DISCONNECTED FROM N/w"

after ur last post,i also changed the name of wireless n/w to "ankit" and even removed the encryption,but still no progress.And yes,my access point work fines wid windows!!!!
dont know wats wrong...
if u say,i m ready to install all over again,but the only thing is tht i remember that i FIRST INSTALLED LIVE CD....then also there was the same problem, so if u think...i can reinstall it!

Hello ak_k80

Here's a thought.

If you have the live CD, why not run the machine up with it in. I've just done it with my 3945 machine and connected without needing to install.

As soon as the machine had booted there was the NetworkManager icon on the Gnome toolbar, left clicking on it showed me the two wireless networks around, mine and another. Left clicking on my network prompted me for the WPA key, I entered it and I'm connected.

That avoids installing again if it doesn't work.

If it doesn't we'll really have to think again.

If it does then you can think about reinstall.

By the way, lots of places in Linux don't like spaces in paths and filenames. If you are using a graphical file manager it will usually smooth over any spaces, but if you are using the command line to say CD to cd (change directory) to a folder the process will fail with spaces.

The space caused the fail in the command I referred to above.

Although we use a lot of graphical tools for networking, they are usually just front ends to command line utilities and spaces can still cause them problems.

It's a throwback to the Linux/Unix past. Windows of course doesn't worry about spaces in paths or anything else.

Something to remember in your Linux journey.

hello bbfuller,
Thanks for tht tip on linux,i'll surely keep tht always in mind!about LiveCd,i just did wat u said...i booted frm d cd and checked n/w manager,but it is also the same...no n/w is listed there,only CONEECT TO OTHER WIRELESS n/w is highlited...on doing the same,it responss the same..i even tried iwlist scan,but again the reply was Resource temprorily......its making no difference!!
BTW,wen i SHUT DOWN fedora..a black window appears in which it shows stopping all services and devices..there is an entry smthin "irqbalance" it alwayss say FAILED corresponding to it!!by any chance it has any connection wid wlan0?
