Network mode: Create a wireless network vs. Extend wireless network via ethernet
Can some one tell me the difference between configuring AirPort Utility : Network mode: Create a wireless network vs. Extend wireless network via ethernet? I connect my cable modem to my Airport Time Capsule to a network switch via ethernet. The switch contacts to three Airport Express (AE connects to two Apple TVs via Ethernet) and another TC. Which is the best mode to configure my network?
Thanks
