How can I add a reserved LAN ip address in a residential router

I have a LAN device which needs a fixed LAN IP address. How can I set that up? The Xfinity app doesn't seem to offer that option.

Hello @user_0x4rn6, thank you for posting on our Xfinity Forums Community platform! Yes, there is a way for you to add a fixed LAN IP. 

 

Just to double-check, were you able to go through these steps in the Xfinity app?

Xfinity App / WiFi / View WiFi Equipment / Advanced Settings / LAN & WAN

 

That’s where the option to manage connected devices (including assigning a reserved LAN IP/DHCP reservation) should appear.

If it still isn’t showing up for you, you can also do this through the Admin Tool at http://10.0.0.1 under Connected Devices.

For more help, here’s our support article Issues-Connecting-Devices-WiFi-Network here.

Let us know any of these steps works for you? We're happy to help!
