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.
