Hi great work and thanks.

I have been trying for a few days now to get a new encrypted system up and running from a already known working non encrypted one.

The problem is under experimental-initramfs-wifi the wifi driver loads but i never comes up. 

Below is the following errors i get with putty when i follow via tty

I have also been able to compile in a a new wifi module 8821cu that also loads but i get the same error.

Unit: Raspberry pi 2 OS: as in config file WIFI: wifi card DWA-131 r8712u WIFI: wifi card cudy WU650 8821cu

any advise would be great. Thanks

Greetings, Not really sure, I at this time, only test on rpi3b+ and rpi4. I did do a sample run on next-4.x branch with:

rpi3b+ and examples/kali-encrypted-basic-dropbear and all wifi settings set

Run was successful and luks unlocked over wifi. You might try the examples/kali-encrypted-basic-dropbear and see if works for you. Please verify the image from kali you need for your hardware.

I at this time, only test on rpi3b+ and rpi4

These have onboard WiFi and which limits the type of case i want to used at a distance, there is no IPEX connector for external antennas

I have got it  working partly with using your examples/pios-encrypted-basic-dropbear as the base for the install and then setup my WiFi manually.

I then look looked at the hooks/0000-experimental-initramfs-wifi.hook and followed the link to the references notes,    http://www.marcfargas.com/posts/enable-wireless-debian-initramfs/ which has a  git gist page.

There i used the scripts in my tests and found that i was still getting the same errors and complaints about wlan0.

I decide change INTERFACE="wlan0" to INTERFACE="wlx28107bb6d4ac" ( mac address of the wifi card ) and also

/sbin/wpa\_supplicant -i$INTERFACE -c/etc/wpa\_supplicant.conf -P/run/initram-wpa\_supplicant.pid -B -f /tmp/wpa\_supplicant.log

to

/sbin/wpa\_supplicant -Dnl80211,wext -i$INTERFACE -c/etc/wpa\_supplicant.conf -P/run/initram-wpa\_supplicant.pid -B -f /tmp/wpa\_supplicant.log

i added ip=:::::wlx28107bb6d4ac:dhcp:1.1.1.1:1.0.0.1 to /boot/cmdline.txt

Now the WiFi came up but I still having ifconfig complained about too many parameters, so i change above to match

ip=:::::wlx28107bb6d4ac:on.

Now it all working  and pulling a it own ip address, dns still gives me errors when i add.

Predictable-Network-Interface-Names was the problem for me with wlan0

Fixed by creating /etc/initramfs-tools/10-rename-network.rules with

SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="28:10:7b:b6:d4:ac", NAME="wlan0"

then in /etc/initramfs-tools/hooks/enable-wireless added

copy_file config /etc/initramfs-tools/10-rename-network.rules /usr/lib/udev/rules.d/10-rename-network.rules

This problem has now been fixed for my but i hope this information helps other stuck with the same or similar problem
