Does hard-wiring pods improve WiFi performance?
Having Ethernet cabling in your home provides a large advantage in terms of the WiFi speeds you can achieve.
When Ethernet is not available throughout the home, the pods will use WiFi to back-haul the traffic to your modem. However, if you have Ethernet in your home, you can connect the pods to the Ethernet jacks in your home and the back-haul traffic will travel over the Ethernet cable. This leaves more airtime available for the WiFi network for increased WiFi speeds.
Also, because you are using the Ethernet to back-haul traffic instead of WiFi, you may be able to space the pods a little further apart since their connection to each other is no longer over WiFi.
