Why can’t I release a reserved IP address in xfi router?
I have a number of devices that I no longer use but for which I reserved IP addresses in my xfi router. I want to free those addresses for use with the replacement devices. In the past, I had some success by forgetting the device if it showed up as offline in the Xfinity app, but these devices long since stopped appearing in the app. It does not appear there is any way to delete or block offline devices in the router UI, either.
I presently have ten offline devices on the “connected devices “ list in my router interface. Some of them used to have reserved addresses, but I have changed them back to DHCP. However, the router does not release the reserved address even though I have stripped it from the offline device. When I try to assign the same address to the replacement device, I get an error message saying that the address has been reserved for another device, even though that address is not then in use.
I have had home internet since the 1980’s and have owned routers from half a dozen brands. Until I started to use the xfi, I never had seen a router that did not have an explicit means of releasing a reserved addresses for a device no longer in use.
Searching this forum, I have learned there is no apparent means of accomplishing what I want with this router, short of a complete factory reset, which always is a recipe for disaster on a network with as many devices as mine serves. I am posting this question, anyway, in case someone has doe up with a workaround for this since the last forum member asked the same question a year or so ago.
Of course, I could revert to my user-owned equipment, but that would mean living without tech support entirely. Still, given the xfi router’s many UI issues, it may be the smart solution.

Hi there. Thank you for reaching out to us via our forums. Just to clarify, you are trying to forget the devices for which you have assigned the IP addresses. If that is the issue you are having. You would need to access the offline device through the device details and forget the device so that it no longer shows assigned to the gateway.

These devices no longer appear as inactive on the app, so there is no way to forget them using the app. There also is no way to forget them in the router connected devices interface.

I have confirmed with xfinity tech support that there is no way to get the xfi router to release reserved IP addresses even after devices have been forgotten. Xfinity suggested a factory reset, but that would be disruptive, require me to re-reserve the addresses of about 20 devices in total, and would solve the problem only until the next time a MAC address changed as a result of a device image update.

@MikeRubin Did you try to change them not using the app, just logon direct to the router, I think there’s a bug, so when you try to change it, you HAVE to put a word in the comments box, if you don’t you get a error, just a thought
