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!

I have the same question.  

I am able to go to Xfinity App / WiFi / View WiFi Equipment / Advanced Settings / LAN & WAN in the app, but I don't see any option for managing connected devices.  All I see are the following:

    Gateway Address

    Subnet Mask

    DHCP Start Range

    DHCP End Range

    Client Lease Time

If I try to go to 10.0.0.1 like I used to to make changes in my router I get the following:

    "Managing your home network settings is now easier than ever. To manage your gateway settings and other features, please download the Xfinity app."

So 10.0.0.1 no longer works it seems.

If this should be a new separate question, feel free to break it off this one or let me know and I can create a new quetion.

Thanks,

Bill

My problem too, and the Xfinity App doesn't do the job.

bilhen The admin tool does have limited access, but you can still log in. You do have to enable access first. You can do that by navigating to the WiFi tab > View WiFi equipment > Advanced settings > Admin Tool online access, then toggle it on and save

Thanks @XfinityAmandaB 

That worked great.  Thank you so much.  Just what I needed.

I will say that the actual path in the app for me to change that setting was:

View WiFi equipment > Advanced settings > Gateway Admin Tool > Allow Admin Tool access

Your signature box says to mark a reply as the accepted answer, but I can't see how to to that.

Thanks again!

bilhen Thank you for letting me know the update path. You may not see the option to make a solution since you did not make the original post, but by providing the update that helps anyone else checking the same thread.
