You need 2 CPEs 510 one set as AP the others set as Client

if only to send out the signal, the distance away how? You see when I turn on, try a distance of 5 meters no network.

Need to set it up, it's not plug & play
Set channel 149
And need a 5 Ghz device to connect to, like iPhone 5 and up, if you don't have a Smartphone or tablet capable of 5Ghz. buy a NIC wireless card or USB for your Laptop, with 5Ghz ability
