b43-phy0: The hardware RF-kill button still turns the radio physically off. Press the button to turn it on -> BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02) - wlan0 No scan results - cannot connect to wireless router using Dell Inspiron B130 in Ubuntu 9.04

Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -C usb; uname -a; dmesg | grep ound; dmesg | grep b43; dmesg | grep iwl; iwconfig; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread

Regards,

Mark

Please try this procedure:

Please make sure the /etc/network/interfaces file only contains the following 2 lines (you can edit the file using the command gksudo gedit /etc/network/interfaces) :

auto lo
iface lo inet loopback

During boot, press F12 (or maybe F2) to enter the BIOS setup. Make sure the wireless setting in the BIOS is set to "Controlled by OS or FN Key". If the wireless BIOS option "By application" exists, choose that option instead. Save this change to the BIOS and exit to resume booting.

Try pressing the wireless hardware button on and off to see if it activates the wireless

Make sure your wireless adapter is turned 'on' (Fn + f2 should be the key combination for activating wireless) Fn+F2 normally toggles wireless on and off and the wireless state change survives through a reboot.

Please read this too:

http://www.mepis.org/node/11915

If wireless is still not working after pressing FN-F2 and rebooting, then proceed with the rest:

Reboot again.

Press F2 (or maybe F12) during the dell boot screen to enter setup.

In setup, go to onboard devices and turn the integrated NIC off

go to wireless and make sure Wireless control is not 'off' and wireless devices is 'on'

Save setup and continue to boot

And for testing purposes, disable encryption and enable SSID broadcasting on the wireless router

Then retest wireless.

If wireless still does not work, try installing wicd to replace Network Manager by using the following commands:

sudo aptitude update
sudo aptitude install wicd

After installing wicd, reboot and retest wireless

Thanks Mark Rijckenberg, that solved my question.

Mark,

Most of the answers are for a dell computer. My computer is a acer aspire 3002wlmi.

In the bios menu is NO option 'wireless settings' nor is there a option 'onboard services'.

I'm not able to test your suggestions. Is there anything else I can try?

Sorry for this Mark but here I go again. My hard drive crashed this week and after I installed a new one it will not recognize my wireless network. I have re-followed the steps from above but still not luck. Also I cannot view DVD's as I get an error, but one problem at a time. Are you still able to help me? Thanx. Steve

I think this is very tough issue to solve because when my friend faced it in his device I remember we uninstalled the software and re installed it again as you can see here https://routerinsider.com/ some detailed information about it.
