Hi guys,

After switching from Linux Mint to Archlinux, my wireless card refused

My laptop is hp 6515b, with a touch panel for the toggle of wifi on/off etc. After a search in google I found the problem may be that the power of wifi has been shut down, and solution is to boot into windows and turn wifi on, because the touch panel will not work under Linux (as far as I know),

After 'rfkill unblock all', I get:

And still no wireless card detected. So my question is, is there any way to power the wifi on without booting into windows? (in fact, windows has diappeared from my laptop for 3 years, and there is no partition on my harddisk supporting windows install). Hi, I don't know if this is gonna help, but when I first installed Arch I had the same problem. What solved it was bringing my wireless interface up manually after activating the wifi switch.

So check out your `ifconfig` output. If you don't see your wireless interface bring it up. `ifconfig wlan0 up`, or whatever your wireless interface name is.

Hi,

Is not ifconfig deprecated now? It is probably not present on the OP's pc. There should be an equivalent command in the replacement. You would probably have to use the following command. I am not sure about the correctness, so please refer to the link.

ip link set wlan0 up

Hi Moncef and Jayesh,

Thank you for your advice. I've tried both 'ifconfig' and 'ip link set', with 'wlan0' and 'eth1', and both said 'no such device'. So I think it's still a wifi power switch thing. On Fri, 24 Feb 2012 12:25:03 +0100, Tom Gundersen wrote:

I had a similar problem with another HP laptop. I was able to switch on the wifi by pressing the wifi switch when I was in BIOS, but YMMV.

Cheers,

And thank you Tom. I tried pressing my wifi switch when in BIOS. But it is in a touch panel, so I cannot switch it on manually. And I wonder whether your wifi switch is in a touch panel or a seperate button? Thanks!
