How many airport expresses can I connect to my time capsule to act as extenders if they are wired with a network switch?


I would like to put an airport express in my 4 level home and 2 on each level (1 each corner) to act as extenders to ensure that the network reaches every corner. Question is, If i am using a 24 port switch, would it be possible to hard wire 7 additional extenders? Would that cause any problems since the Time Capsule only has 3 extra ports in the back?

    The airports will extend any signal they receive.  If you attach 7 network devices to your switch and plug the switch into the Time Capsule, all 7 network devices will receive the network signal from the TC.... and extend it if configured to do so.

    Good wiring practice would have all your Ethernet devices throughout the house connected to the Ethernet switch.


    Then, the switch connects to one port on the Time Capsule. If your switch has enough ports, you only need one port on the Time Capsule to connect to the switch. 


    That would leave 2 ports in reserve on the Time Capsule if you start to run out of ports on the switch. Or, you can add another switch to the switch.....or to another port on the Time Capsule.

    That's a loaded question.


    There are limits to the number of total devices that can be setup on a network. That is about 250.


    Keep in mind that each AirPort Express can handle up to 50 wireless connections. You'll have to do some math to figure out how many wireless iPhones, iPads, laptops will be connected in total, then add the Express devices as well.


    You could have 100 AirPort Expess devices on the network and still be able to accommodate another 100 wireless devices, like iPads, laptops, etc.


    I administer a network at my grandson's school with one "main" AirPort Extreme, a 24 port switch and 20 AirPort Express devices.


    So 20 AirPort Express devices plus 200 iPads = 220 total devices on the network. The system is flawless, but we rarely have more than 100 users on the wireless at the same time.  It does start to slow down a bit at 150 or so.
