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

show up in lspci. It DOES worked fine under Linux Mint, but .... Below
is
my output of 'lspci -vnn |grep Broadcom' :
10:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M

Ethernet PCI Express (rev 02)
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),
n> And the I found a software named rfkill, hoping it will work. 'rfkill

After 'rfkill unblock all', I get:
0: hp-wifi: Wireless LAN
? ? ? ? Soft blocked: no

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
More information can be found at http://linux.die.net/man/8/ip
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.

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!
