WiFi pod won’t connect to router

Hi, I recently moved home to an xgs pon area, which means I’ve had to change route from old hub 5 which had coax connection from the omni box outside to 5x router which takes the optical fibre connection from the omni box.

i had a WiFi booster pod the black one with my previous router, I can’t seem to get it to connect to my new router it constantly flashes white as if it’s trying to connect but can’t. 

does anyone know if there’s a work around this or will the pod be assigned to my old router only? 

thanks :)
