There are several things people do at their router that can prevent setup of IoT devices (MAC filtering, DHCP address limits, etc). This was written for the old Plug, but most of it still applies. Give it a look and see if anything applies to you:
After reading great reviews, I bought the 2-pack Wyze Plug, 2021 version, to replace C for GE plugs that have been less than satisfying.
Unfortunately, I can’t get either of these Wyze plugs to connect, although they say they are pairing first.
Just spent an hour on the phone with Wyze customer support, and they weren’t able to help.
I’ve got CenturyLink 1 gig service and am using Orbi Modem and Satellite. Is it possible there is something about the Orbi setup causing an issue? I don’t have connection issues with the C for GE plugs.
