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),
n> 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
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.

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!

Not quite sure what you mean by "touch panel", I guess mine is not though. It is a Fn+<something> combination.
Cheers,

don't forget that you need b43-firmware from aur as well.

IIUC he needs a GUI to press the button?! There's no "real" switch?!
Anyway, I installed Ubuntu to get my Wi-Fi USB adapter supported, it still doesn't work as needed, but already is available, IOW my iPad is able to "see" the USB adapter of my Linux PC, but I don't get an Internet connection, or anything that is stable, instead of being connected and disconnected and connected and disconnected ... all the times.
If I should get it working with Ubuntu, I'll compare it with my Arch Linux for troubleshooting.
Wi-Fi is a PITA and I experienced Arch as more problematic as Ubuntu "might be".
I also don't have a Windows installed, resp. I've got an install for VirtualBox on Arch Linux with a Windows to run an iThingy as long as WLAN doesn't work.
Wi-Fi seems to be an issue with Linux, I'm uncertain to install a Windows, I already hate to run it with VirtualBox.
Regards, Ralf

Seems you have had bad luck. Most wifi devices work well with Linux these days, of course assuming you have installed the right drivers / firmware, and that they are not blocked by the firmware which seems to be the issue in this thread.
When it comes to usb adapters, the vendors have a tendency to do very evil things. In the past I have needed usb_modeswitch to be installed to make things work, but YMMV.

Thank you, it's an USB device. Installing usb_modeswitch (and a restart) didn't change anything. For a vanilla install of Ubuntu the USB adapter's LED will flash, it doesn't for Arch Linux. I don't want to capture this thread. If needed I'll open a new thread, when I again start to get it working with Arch Linux.
