# Using multiple base stations in an Ethernet network

You can set up multiple AirPort Extreme Base Stations or Time Capsules to create a single wireless network (known as a “roaming” network).

## To set up a roaming network:

1. Connect all the base stations and Time Capsules to the same subnet on your Ethernet network and give the same network name and password to each device.

2. To assign IP addresses to clients on the network using Dynamic Host Configuration Protocol (DHCP), set up one device as the DHCP server. To do this:

- Open AirPort Utility, located in the Utilities folder in the Applications folder on a computer using Mac OS X, and in Start > All Programs > AirPort on a Windows computer. Select the device you’re setting up as the DHCP server, and then click Manual Setup.

  Make sure the device assigns a range of real IP addresses. Private IP addresses used by Network Address Translation (NAT) cannot be used for roaming. Click Internet in the toolbar, click Internet Connection, and then choose “Distribute a range of IP addresses” from the Connection Sharing pop-up menu.

3. Set up all of the other base stations as bridges by turning off DHCP and NAT. To do this:

- In AirPort Utility, select the device you want to set up as a bridge, and then click Manual Setup. Enter the password if necessary.

  Click Internet in the toolbar, click Internet Connection, and then choose “Off (Bridge Mode)” from the Connection Sharing pop-up menu on the device you want to set up as a bridge.

If you’re using wireless devices that support 802.11n, you can extend the range of the network by setting up a Dynamic Wireless Distribution System.
