Asus laptop, Intel PRO/Wireless 3945ABG, Wireless does not work.

[gintunas]

Just installed Kubuntu 11.10 Everything looks fine except that the wireless does not work. In KNetworkManager, once try 'Scan', nothing in the surrounding is detected. I have just another laptop and it detects a lot of routers.

Additional info below. Would be really thankful for any suggestions how to proceed further.

... abd from the KnetworkManager , I am not allowed to enable wireless, and if I click on wireless interface I get this

Type: Wireless 802.11
Connection Status: Unavailable
IP address: No IP address
...
System name: wlan0
MAC address: 00:1B:77:B8:C9:80
Driver: iwl3945

Can it be that there are problems with the device itself? How one can test it?

[SecretCode]

Have you checked for proprietary drivers in Applications > System > Additional Drivers?

Do you have a keyboard function to enable the wireless? It's normally the blue Fn key and the key with a blue antenna symbol.
- Check output of

rfkill list all

May also help to check

nmcli nm
nmcli dev

Can you activate the interface from the command line using sudo? (Not sure whether you should use ifup or ifconfig ... up or iwconfig...)

(I also have 11.10 on an Asus, but this one has an Atheros wifi card.)

Aside: It's a good idea to post the output of commands between [ code ] tags [/ code]

[wizard10000]

The driver is loading properly or seems to be but iwconfig says the device is powered off. I've got an Intel 3945 card that's not currently installed and it ran out of the box. Stupid question, but did you check the hardware switch on the laptop to insure the card's turned on?

[pookito]

Maybe it is because it is off. Most computers have an actual switch on the size. It might be turned off. Turn it on. U should be alright. If that does not work. Try to turn it on via BIOS. That would help as well. I spent countless hours trying to get my wireless to work when it was that simple

As usual, the best solutions are the simplest ones... I just had to switch manually the card and ... everything works!!! My little daughter loves this computer, especially all the buttons... And sorry for your time.

[dequire]

This thread is why this forum rocks! Well done, people.

[SecretCode]

Do we have a "mark solved" function on the board? (yet?)

Glad you got it sorted. My 11-month old granddaughter turns my laptop off about twice a day - the power button is on the side and is lit up. She pokes it with her finger and the laptop does an orderly shutdown

[SecretCode]

How clean are your granddaughter's fingers, on a normal day?

*waits for thread on cleaning jam and silly putty out of power button*

The larger issue is why I can't set the power button to "Do Nothing" in the power management applet

[SecretCode]

And why is that? I hope you mean that you have neglected to do it just yet ... or is it actually not possible on your system?

[wizard10000]

The setting doesn't work. It's set to "Do Nothing" now and the power button still shuts the machine down

[SecretCode]

Odd. Sounds like a bug.

Have you tried setting it to "prompt logout dialogue" and seeing if it takes effect? This will still power down after 30s so don't leave it at that. But if it works, maybe setting it back to "Do nothing" would stick.

It's worth a shot
