 If you are struggling with this tutorial and still want to try OpenIPC on a Smartwares CIP-37210, you can [buy it with OpenIPC v2.2 firmware pre-installed at open collective](https://opencollective.com/openipc/contribute/wifi-camera-showme-by-openipc-44355).
 
 ## Connecting to wifi
-Now it's time to connect the camera to your 2.4 GHz Wi-Fi network. First of all, make sure that the firmware environment variables are set correctly. This is necessary so that `udhcpc` gets a DNS lease (because it is requesting `$ipaddr`) and the gateway is set correctly.
+Now it's time to connect the camera to your 2.4 GHz Wi-Fi network. First of all, make sure that the firmware environment variables are set correctly.
+
+First set the network driver:
 
 ```sh
-fw_printenv ipaddr
-fw_printenv gatewayip
-fw_printenv netmask
+fw_setenv wlandev rtl8188fu-generic
 ```
-Set the correct values according to your needs, for example:

+Then the correct values according to your needs, for example:
 ```sh
-fw_setenv ipaddr 10.42.42.42
+fw_setenv wlanssid guest
+fw_setenv wlanpass guest-password
 ```
-The last step is to configure the wlan0 interface:
+
+You can check the settings as folows:
 ```sh
-vi /etc/network/interfaces
+fw_printenv wlandev
+fw_printenv wlanssid
+fw_printenv wlanpass
 ```
-Delete or outcomment the eth0 block, the device doesn't have ethernet and the auto setting will slow down boot. Add the following lines to your interfaces file, alter your SSID and password accordingly.

+Now it's time to check whether it's working:
 ```sh
 ifup wlan0
 ip addr
 ```
 Check whether you can ping and ssh into the camera. Reboot and check, if the camera connects automatically to your wifi network. Reassamble the camera, now it's time so say goodbye to UART and use ssh and the web interface. (The credentials are root and the password you set earlier.)
+
+Finally, you should look at `/etc/majestic.yaml` and in particular set this sections as follows in order to have a correct GPIO mapping for nighmode and audio.

+  volume: 70
+  srate: 8000
+  codec: alaw

+  irCutPin1: 64
