View Full Version : [ubuntu] How do I check if my wireless card is installed?

How do I check if my wireless card is installed? It is blacked out in the "network applet" and the physical button does not do anything.

Ubuntu 10.10
Intel® PRO/Wireless 3945 a/b/g

Edit: the sysinfo application crashed on me before but I does look like my wireless card is installed. Which brings me to my next question: How do I turn it on?

rfkill list all

Returns: 0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

Open a terminal and copy and paste into a terminal each of these commands (they are case sensitive)

sudo lshw -C network
lspci -nnk | grep -iA2 network
lsusbPost the results back here by copying and pasting from the terminal into your next post. Enter your password when asked. It will not be echoed to the screen. This is normal.

Kind regards

What is the make and model of the PC/laptop ?

I assume you have checked the wireless kill switch to make sure wireless is enabled ?

Kind regards

If you by "kill switch" mean the physical button above the keyboard then yes. It does not do anything neither does the fn+f10 combo and LED is turned off.

Edit: Googled more and found this but it doesn't work either
sudo ifconfig wlan0 up
SIOCSIFFLAGS: Operation not possible due to RF-kill

There was a bug report raised on this


Unfortunately you do not have a Dell or a HP so the solutions there will not help you.

There may be a backport for you from natty. Have you had a look ?

In the meantime i am looking for a solution. If others know of a solution i am sure they will chime in.

Kind regards

Thanks Matt.

I haven't been using linux in a couple of years and I just switched to 10.10 a couple of months ago from windows so I am not entirely sure what you men by "backport".

Anyway, I use my computer pretty much as a desktop with a wired internet connection so it isn't a big deal for me. It's just a shame when everything else works so perfectly. I didn't even have to install any additional drivers like I had to do in windows.
