Sorry to hear this is still not working for you Carlislepete
Please ensure that the pod is in a mains socket (not in an extension) as close to the router as possible.
I recommend to try a 60 second pin hole reset on the router. This will revert any customisations back to factory settings and full update the router with firmware/software updates. Please do not reboot the router whilst it is completing the pin hole request.
The pod should flash for 15 minutes whilst communicating to the router and then stop flashing when it's ready to be positioned in the home to boost the coverage further.
