+Example how to convert wlan0 interface settings to the new wifi configuration script:
+
+```diff
+auto wlan0
+iface wlan0 inet dhcp
++   pre-up devmem 0x100C0080 32 0x530
++   pre-up echo 7 > /sys/class/gpio/export
++   pre-up echo out > /sys/class/gpio/gpio7/direction
++   pre-up echo 0 > /sys/class/gpio/gpio7/value
++   pre-up modprobe mt7601u
+    pre-up wpa_passphrase "SSID" "password" >/tmp/wpa_supplicant.conf
+    pre-up sed -i '2i \\tscan_ssid=1' /tmp/wpa_supplicant.conf
+    pre-up sleep 3

+!   post-down echo 7 > /sys/class/gpio/unexport

+### Wireless credentials
+
+For the initial setup, the device will create an access point with the name OpenIPC and password 12345678.
+
+The accesspoint will be automatically closed after 5 minutes to prevent misuse.
+
+After connecting to the device, credentials can be changed with a builtin script:
+
+```
+wireless setup [SSID] [PASS]
+wireless connect
+wireless show
+```
+
