How to set up IP Address Reservation on a NetGear DG834G
From PhonePower Knowledge Base
To set up IP address reservation with DHCP, please follow these steps. This will ensure that the Phone Power device will receive the same IP address every time you power cycle it without the need to configure a static IP.
For the first step in this process, we will need to find out the current IP address being assigned to your Grandstream by your router. Please refer to How to receive the current WAN IP Address on a Grandstream for more information.
Open up a web browser and navigate to http://192.168.1.1 to log into the router.
Click LAN IP Setup.
Under Address Reservation, click Add.
In the next screen you will see a list of connected computers.
Note: The MAC address of the Phone Power device will be displayed on the sticker on the bottom of the device, however, the router will show the same number, but the last character will be one higher than what is displayed on the sticker. This is because the WAN port and the LAN port of the Grandstream have unique MAC addresses. As far as the router is concerned, the WAN MAC address is the relevant MAC address.
Give the device a name of your choosing and click Add.
Save the settings.
You will need to reboot the Grandstream device for this to take effect. Simply remove the power cord from the back of the Grandstream, wait 20 seconds, and put it back in. If you are unable to place a call after 15 minutes, please contact our support department for additional assistance.
