Hi Vladimir, In fact I've tried 'lspci -vnn | grep 14e4' before, and this is the output, JUST one row: 10:00.0 Ethernet controller [0200]: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express [14e4:1693] (rev 02) If I just type 'lspci' I will not find anything related to wireless card either. About the kubuntu thing, did you mean this? http://ubuntuforums.org/showthread.php?t=1349025 I've read it before open this thread. My problem is just the same as that of stark222000: it's wifi card CANNOT be powered on, not that driver thing listed in archwiki or linux wireless. He solved it through booting into windows. But I don't have windows installed and I don't want to install it anymore. So I opened this thread as 'how to power on my wifi card' instead of 'my wifi card dose not work', which will of course be classified as a driver issue. And if I missed anything after my explanation, plz let me know. Thanks! On Thu, 23 Feb 2012 17:07:03 +0900, Vladimir Lomov wrote:

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 Gigabit Ethernet PCI Express (rev 02)

Sorry, if you find my answer a rude but did you use search engines? See wiki.archlinux.org? E.g. https://wiki.archlinux.org/index.php/Broadcom_wireless

IMHO, proper command must be $ lspci -vnn | grep 14e4

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),

Ah, broadcom and HP (6515b), something familiar. I remember a problem with HP notebook with broadcom wireless card about a year or two ago. The problem was solved by downloading kernel module source compiling then and installing (not Archlinux, Kubuntu).

This Google returns me for "broadcom linux bcm4311"

And the I found a software named rfkill, hoping it will work. 'rfkill list' out put as follows :

...

0: hp-wifi: Wireless LAN Soft blocked: yes Hard blocked: yes

...

After 'rfkill unblock all', I get:

...

0: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes

...

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).
