All computers/devices that connect to a network get an IP Address (an IP Address is a number used to identify the specific device. Think “street address”). Computers can acquire this IP address one of two ways:
- They assign one to themselves.
- They can choose to get one from the router itself.
Every time a computer disconnects/reconnects to the router, or turned off/on a new IP address is assigned to it by the router. Any port forwarding/remote access rule in the router is based on the computer’s IP address. Using port forwarding/remote access rules the computer in question is required to be assigned the same IP address assigned from the router. DCHP Reservations provide this functionality.
Things to do before setting this up:
- Make sure the router firmware is up to date.(How to Verify Firmware Version)
- Make sure the device you want to set up the reservation for is turned on and connected to the router via Wi-Fi or Ethernet.
- You will need to know the CURRENT IP Address of the device you want to set up a reservation for at this time.
How to set Up DHCP Reservation:
- Log into the routers administration page (login instructions).
- If you see a button in the top left that says Basic Mode, click on it. It should now say Advanced Mode (Depending on the firmware version and the router, you may not see this button)
- Click the Network Settings tab then select DCHP Server.
- Locate the Active Leases section then find the IP Address of the device in question select it then click Reserve.
What if this Doesn’t Work?
- Try doing a hardware reset of the router. This will return all router settings to factory default, so then follow the instructions to set up the reservation again. (Hard Reset instructions)
- Try clearing your browser’s cache. Most browsers (IE, Firefox, and chrome) allow you to do this by pressing “CTRL” + “F5” on your keyboard. (Clear Browser Cache)
