Hi there,

I'm new to Ubuntu, but I'm really liking it more than Windows. :)

I always have problems with hardware when switching OSes and unfortunately, Ubuntu has not been any different. Fortunately, most of the hardware has been detected, but there's one which is really driving me nuts. It's my builtin wireless card (I'm running a HP laptop)

I'm still a bit of a dunce with linux commands, so please bear with me.

I have a power button on my wireless, which I turn on (it turns on Bluetooth too)

Bluetooth works, and I can pair devices. No matter what I try, I cannot seem to get my wireless card to pick up any networks, nor can I see it in the Network applet.

I really could use some help. :P

Hi

Could you open a terminal menu>acccessories>teminal

Enter the following


iwconfig

and post the output here. We will see if it is configured.

Have you right clicked on the network icon at top right and selected "enable wireless"?

Here we go:


#: iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wlan0 IEEE 802.11abg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=off
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off



Re your second point: "Enable Wireless" is not selectable.

Can I bump this topic? I'm still no closer to an answer than previously?

In the time it took to get an answer on this, I've been able to find out, by chance what was going on. I had a hard and soft block on my wireless card, which I fixed by doing


sudo rfkill unblock 0

Where 0 was my wireless card id in the rfkill list. After that, I turned off and on my card and it worked.

Hi again

Glad you solved it. I was about to say that your card - last line in you lspci list - is pretty standard and normally works OK.............

Thanks for your help -- you nudged me in the right direction by getting me to check the hardware. :)
