+To enter promiscuous mode on a ThinkPad T60, a monitor device needs to be created. Follow the steps below to get it working:
+<code>iw dev wlan0 interface add mon0 type monitor
+ifconfig mon0 up
+ifconfig mon0 promisc</code>
+Now, package dumping should work on ''mon0'' and ''wlan0''. The monitor device also emits all low level WLAN packets.

+===== cryptroot missing after updating to Debian testing =====
+After updating from Debian stable to testing, the file cryptroot in /etc/initramfs-tools/conf.d is missing. Extract it from a previous initrd and put it back. Old initrd images can be extracted using
+<code>
+gzip -dc /boot/initrd-XXXX | cpio -id
+</code>
