The way I do it
I created the passphrase as described and moved it to /etc/wpa_supplicant/wpa_supplicant.conf and did rc-update add wpa_supplicant. Then I let dhcpcd service handle the wlan0 interface, bascially, keep only the lo interface in /etc/network/interfaces and then start dhcpcd service. --Ncopa 08:19, 25 January 2011 (UTC)
An unfortunate mix
This page is an unfortunate mix of how bring up a wireless interface on a running system vs. how bring up a wireless interface at boot time. Those topics should be discussed separately and they are not. It's possible to tease the information out of this, but it's much more difficult than it should be.
- I agree, same goes with 'Broadcom Wi-Fi Chipset Users' which I just updated. It can stay on the same page, but it should be separated into sections? --Mark (talk) 04:20, 18 March 2017 (UTC)
