Thanks Alan, I follow your instruction and it works eventually! But I got another question:
- I am using official Raspberry-PI WIFI dongle (BCM43143) - I configure kernel so that driver "brcm80211" is enabled, however, WIFI is not working. - Then I add driver "ipw2x00", then WIFI works. - So my question, why do we need both "ipw2x00" and "brcm80211" for official Raspberry-PI WIFI dongle? - (Sometimes the WIFI dongle works if I add drivers: "brcm80211, iwlwifi, rt2x00", without "ipw2x00", so I am really confused!) Thanks!
