To enable wifi on a raspberry pi:
If you did not already add the ethernet type to cmdline.txt before running Plan 9:
% dossrv; mount /srv/dos /n/9fat /dev/sdM0/dos
Use sam -d to edit /n/9fat/cmdline.txt:
readparts=1 nobootprompt=local console='0 b115200' ether1=type=4330
Afterwards, reboot:
% reboot
To enable wifi:
% bind -a '#l1' /net
ether4330: chip 43430 rev 1 type 1
ether4330: firmware ready
ether4330: addr b827eb2a85bf
% aux/wpa -2 -s 'YOURESSID' -p /net/ether1
!Adding key: essid=YOURESSID proto=wpapsk
password:
!
% ip/ipconfig ether /net/ether1
% ip/ping -n 5 1.1.1.1

To automatically start wifi upon boot, put these lines in /cfg/$sysname/termrc or cpurc:
bind -a '#l1' /net
echo 'key proto=wpapsk essid=ESSID !password='^`{cat /lib/wpa/ESSID} > /mnt/factotum/ctl
aux/wpa -2 -s 'ESSID' /net/ether1
ip/ipconfig ether /net/ether1
Put the wifi password in /lib/wpa/ESSID.
