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).
