Plum Lightpads use the 2.4ghz frequency band. If you have a dual band router and the 2.4ghz and 5ghz bands have the same SSID, Plum recommends that you login to the router admin panel and separate them by giving them each a unique name. When you provision the Lightpad to your WiFi access point the first time, your smart phone will need to be connected to the same 2.4GHz network that you want your Lightpads to be connected to. After provisioning, your smart phone can be connected to any WiFi network or to any WAN network.
example: [Mywifi_2.4ghz / Mywifi_5ghz]
Plum recommends WPA-2 security on your WiFi network.
If your SSID is hidden, you will need to unhide the network temporarily when you are provisioning the Plum Lightpads. After provisioning the Lightpads to your WiFi network, you may re-hide the SSID if you’d like.
