+Repack live
+===========
+You might want to save the state of your live system to the usb stick. In order
+to do so, run the following commands:
+
+apt update
+apt-get install -y cpio pigz
+rm /etc/rc.local
+# remove '#' before allow-hotplug
+vi /etc/network/interfaces
+mount /dev/sda1 /mnt
+mv /mnt/initrd.gz /mnt/initrd.old
+cd /
+find . -xdev | cpio --quiet -H newc -o | pigz -9 > /mnt/initrd.gz
+umount /mnt
+
+iwd
+===
+With iwd you can force to use 5ghz. The following needs to be done to get iwd
+running.
+
+sudo apt-get install iwd
+
+cat <<EOF > /etc/iwd/main.conf
+[Rank]
+ BandModifier5Ghz=10
+EOF
+
+# Remove or comment out the following interfaces from /etc/network/interfaces
+# allow-hotplug wlp1s0f0
+# iface wlp1s0f0 inet dhcp
+# wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
+
+# Add the following interfaces to /etc/network/interfaces
+allow-hotplug wlan0
+iface wlan0 inet dhcp
+
+# Reboot
+reboot
+
+# Configure iwd:
+sudo iwctl
+device list
+station wlan0 scan
+station wlan0 get-networks
+station wlan0 connect SSID
+
+Deinstall Linux
