[arch-general] Ways to power on broadcom bcm4311 wireless adaptor without booting into windows
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) 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), 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).
Your BIOS migt contain a wifi swich.... Sent from my phone. Sorry for any spelling mistakes
Thanks Jesse, I'm afraid there's no wifi switch in BIOS. Actually, BIOS options related to LAN/WLAN are as follows: LAN powersaving: disable Embedded WLAN Device Radio: enable Network Interface Controller(LAN): enable LAN/WLAN Switching: enable Wake on LAN: enable I tried to toggle these options except the first one enabled/disabled, but still no luck. Any suggestions? On Wed, 22 Feb 2012 17:42:50 +0200, Jesse Jaara wrote:

Hi guys,

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" http://www.broadcom.com/support/802.11/linux_sta.php http://linuxwireless.org/en/users/Drivers/b43
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).

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 -- ------------------------------------------------------- Cheers Jayesh Vinay Badwaik Electronics and Communication Engineering VNIT, INDIA -

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, Tom
