WCO base station

The setup video is lacking My cable/WiFi is in the basement. Set up for the WCO says plug into the router for setup but there’s no mention of does it have to remain plugged in or can I unplug and move after it’s setup???

Just going by what I’ve read here the base station must be attached to your network via wired Ethernet at all times. This can be accomplished via a WiFi extender/bridge to Ethernet if necessary.

As @customer stated the WCO base must remain plugged into your router or another Ethernet access point, the WCO cam itself is what you can relocate to another place
