Thanks so much for posting your inquiry in the community! 🙂
I can understand how convenient it would be to be able to extend your WiFi coverage to your pool house. There should not be any issues doing this.
Pod placement is very important to consider. If the pods and the modem are too close together they can cause interference with each other. If the pods are too far away from the modem, another pod, or if the signal is weak in that area, then the pods will not function well.
Keep the community posted if you are having issues and we can help troubleshoot it for you.
