Why cant I remove a device from my wireless Fios router?

Question

I have some APC "smart" surge protectors, but they work terribly so I'm considering just turning off the wifi part.  Unfortunately, I dont see any way to do that from the plug itself, so I'm looking at the devices connected to my router.  There seems to be no way to delete an active device.

So now I have these old wireless standard surge protectors that I cannot remove from my network and the Fios app is telling me that their old standard is slowing down the devices on my network.  How do I delete these two "smart" devices?  I can block them, but it still shows them as connected and just blocks traffic.

If the router sees the UPSs actively connected, that might be the reason that they cannot be removed. Does APC have the instruction guide for the UPSs available for download? If so, check to see if there is a way to disable the Wi-Fi functionality. Once that has been done, reboot the router and see if they can be delisted.

The other option would be to remove the UPSs completely, move them far away from the router, reboot the router and see if they appear as offline.
