I tried following[1]: I opened the boot partition of the sdcard and copied cmdline-wifi.txt -> cmdline.txt
$ cat cmdline.txt
readparts=1 nvram=#S/sdM0/nvram ether1=type=4330
I don't understand these options, so I did not change anything. Booting Plan9 gets stuck on the console:

What exact changes do I need to make to be able to connect to a WiFi network with WPA2?
Thanks!
