 To open the gateway, put it down with the antenna socket at the top and (gently) lift the left and right sides of the white shield.
 
 To close the gateway, align the lid and push firmly at the sides so you can hear it snap in place.

 Upon every power cycle and every 24 hours, the gateway checks for a new firmware. If the latest firmware is not downloaded yet, it will download the new image and perform a reboot in order to install the new image. This can take up to a few minutes. The process is indicated by a flashing power LED. Power cycling during this process is not dangerous, but this process will be restarted on the next start-up, so please be patient!

+### My gateway is in a reboot loop. How can I fix it?
 
 A possible cause of this issue is that the LoRa board is not fully pushed in in the socket. Open the lid and push the LoRa board in the socket. If this fix does not work for you, check the [product repository](https://github.com/TheThingsProducts/gateway/issues), browse through issues to search for solution or file a new issue.

+### My gateway stays in AP mode. What do I do?
 
 This behaviour occurs when there is a glitch in the WiFi connection of the gateway. When this happens, your gateway will turn into an AP and devices you used to set up the gateway can connect to it (your laptop or phone). To avoid this, you should remove the gateway from the list of APs from your laptop/phone (*Network Settings &#8594; Things-Gateway-XXXX &#8594; Forget this network*).

 The gateway has a UART port on which it prints debug messages. To see these messages you need to connect a device between the gateway and your computer that can read out a UART (e.g. an FTDI cable/board).
