Wireless with wicd on HP Pavilion dv5000 on Ubuntu

**jayd512** · 03-27-2010

From the Ubuntu Forums... it involved a different module, but maybe it'll work for you.

Code:

rmmod b43
rfkill block all
rfkill unblock all
modprobe b43
rfkill unblock all
ifconfig wlan0 up

I changed, in red, the module you might have to use.

Code:

ben@ben-laptop:~$ rmmod b43
ERROR: Removing 'b43': Operation not permitted
ben@ben-laptop:~$ rfkill block all
ben@ben-laptop:~$ rfkill unblock all
ben@ben-laptop:~$ modprobe b43
ben@ben-laptop:~$ rfkill unblock all
ben@ben-laptop:~$ ifconfig wlan0 up
SIOCSIFFLAGS: Permission denied

I did all that. Still doesn't seem like it's working. If anyone has any other ideas or would like to see any more output, let me know.

Try running those 2 that failed with sudo privileges:

Code:

sudo rmmod b43

then the rest of it...

Code:

sudo ifconfig wlan0 up

Code:

ben@ben-laptop:~$ sudo rmmod b43
[sudo] password for ben: 
ben@ben-laptop:~$ sudo ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device

HHmmm...
Maybe we have the wrong interface name. Execute

Code:

ifconfig -a

This is odd... It should be working for you

Let's do this... (reed9's commands)

Code:

dmesg | grep firmware
iwconfig
sudo iwlist wlan0 scan

Is there an On/Off switch for the wireless? Is it turned on?

Enter this command:

Code:

 cat /sys/class/rfkill/rfkill0/state

It should return with a 0 or 1

0 = off
1 = on

What do you get?

This one returns a 2. I did think of that. There is a wireless button on the keyboard that in Windows used to light up when active. This never lights up although I dried toggling it.

Code:

ben@ben-laptop:~$ cat /sys/class/rfkill/rfkill0/state
2

To Jay,

Keep in mind, I just keep checking wicd to see if it says any wireless networks are found, but it still says none. Is there anything else I should do in wicd?

Code:

ben@ben-laptop:~$ dmesg | grep firmware
