Extending a network with two Airport Extreme Base Stations
I am trying to extend my network with two Airport Extreme Base Stations. They are both 4th generation base stations. One I have had for a long time with and it works with no problems. The other I just bought used today and I am trying to get it set up. The configuration I want to utilize is a wireless extended network. I have a wireless thermostat now and need a strong internet connection close to it since its antenna is incredibly poor.
I have followed Wi-Fi base stations: Setting up and configuring an extended wireless network (802.11n) this guide and have been extraordinarily unsuccessful. I have been able to configure the extended network over Ethernet but that does not work for what I want and need to do.
If anyone has some Ideas I surely would appreciate the help. I think I am really close but am missing something that is key to the process. I am using Airport Utility 6.3.2.
