Wi–Fi base station - Any variety of AirPort Extreme Base Station, AirPort Express, or Time Capsule.

Extending a wireless network - Using multiple Wi-Fi base stations wirelessly to extend the range of an AirPort network over a wider physical area, when the range of a single base station is insufficient.

Before we begin looking at how a Wi-Fi extender can help your home network, let’s consider some of the descriptions you might have seen. Wi-Fi range extenders are sometimes called Wi-Fi boosters, Wi-Fi repeaters, internet boosters or Wi-Fi amplifiers.

Multi Wi-Fi base station network - A network that utilizes more than one Wi-Fi base station to extend the range of a network, or to extend features such as Internet access, music streaming, printing, storage, etc. The Wi-Fi base stations may be connected together via Ethernet or wirelessly.

• WiFi Range Extender Boosts the range of your existing WiFi and creates a stronger signal in hard-to-reach areas. When the wireless device connects through the extender to your router, the MAC address of the wireless device shown on the router is translated to another MAC address. If your router’s MAC filter is.

Wi-Fi Client - A Wi-Fi client is any device that uses Wi-Fi (access to the Internet, printing, storage, or music streaming). Client examples include computers, iPad, iPhone, game console, digital video recorder, and/or other Wi-Fi devices.

Primary base station - This is typically the base station that connects to the modem and has the gateway address to the Internet. It is common for the primary Wi-Fi base station to provide the DHCP service for the Wi-Fi network.

Extended Wi-Fi base station - Any Wi-Fi base station that connects to a primary Wi-Fi base station to extend the range of the network. Unless otherwise indicated, extended Wi-Fi base stations should be set to use bridge mode.

Throughput - The amount of data that is transmitted or received each second, measured in megabits per second (Mbps).

Choosing between single versus multiple Wi-Fi base stations

Before you add additional Wi-fi base stations to your network, you should consider whether or not you really need to.

Adding Wi-Fi base stations when it is unnecessary can reduce Wi-Fi throughput because the Wi-Fi network will require more data management overhead. The network configuration also becomes more complex. In the case of a wirelessly extended network, throughput may be reduced to less than 60 percent of that of a single device. The general rule is to keep the Wi-Fi network as simple as possible. You can accomplish this by using the minimum number of Wi-Fi base stations required to service the physical network area and by using Ethernet wherever possible.
Extending the range of your Wi-Fi network by connecting Wi-Fi base stations together using Ethernet is always the best option, and will provide the best throughput. Ethernet offers up to one gigabit rate, which is much faster than wireless (for wireless, the maximum rate is 450 Mbps on 802.11n @ 5 GHz). Ethernet is also resistant to radio frequency interference and is easier to troubleshoot. Additionally, as there is virtually no management overhead over Ethernet, more data will move from one point to another in the same space of time.
Given that, in some environments, a single Wi-Fi base station doesn’t fulfill your requirements, using multiple Wi-Fi base stations can improve your network range and throughput in areas farther away from the primary Wi-Fi base station. Consider that the farther away you are, or the more obstructions between your Wi-Fi client device and the Wi-Fi base station (such as bathroom tile which the signal must attempt to pass through), the weaker the radio signal strength and the lower the throughput.
Assuming that a single base station doesn't fulfill your requirements, you should understand the different methods you can employ to extend your Wi-Fi network range, and choose which of those methods is best for you.

Multiple Wi-Fi base station network types

Learn about the types of networks and how to choose between them.

If you need to extend the range of your wireless network, which method should you use?

For 802.11a/b/g/n Wi-Fi base stations:

• Roaming Network (Recommended)
• Wirelessly Extended Network

For 802.11g Wi-Fi base stations:

• Roaming Network (Recommended)
• WDS

These methods are explained below. At the bottom of this article are links to individual articles that explain the set up and configuration for each method. Wi-Fi base stations will provide an Internet connection with client computers wirelessly or through an Ethernet connection if the client computers are connected to the base station by Ethernet.

Roaming Network (Ethernet-connected Wi-Fi base stations)

For 802.11n Wi-Fi base stations, creating a roaming network is by far the best choice. This will provide the best throughput between the base stations and your Wi-Fi devices.
This set up requires that your Wi-Fi base stations are connected via Ethernet.
The primary base station provides DHCP Services, while the extended base station will be configured to use bridge mode.

All Wi-Fi base stations within the roaming network should use the same passwords, security type (Open/WEP/WPA), and network name (SSID).

You can add several extended Wi-Fi base stations to expand a roaming network.

You can incorporate a network switch if you don’t have enough LAN ports available on your primary Wi-Fi base station.

Wirelessly Extended Network (802.11n)

If you are unable to build the recommended Roaming network, then a Wirelessly Extended Network is the next best option.

To create a Wireless Extended Network you must place the extended Wi-Fi base station within range of the primary Wi-Fi base station.

Extended network range considerations

In the above example the primary Wi-Fi base station ➊ is out of wireless range of the extended Wi-Fi base station ➋, therefore the extended Wi-Fi base station cannot join or extend the wireless network. The extended Wi-Fi base station must be moved to a location that is within Wi-Fi range of the primary Wi-Fi base station.

Important note

If another extended Wi-Fi base station ➋ is placed between the primary Wi-Fi base station ➊ and the extended Wi-Fi base station ➌, the extended Wi-Fi base station ➌ will not allow clients to join it. All extended Wi-Fi base stations must be in direct range of the primary Wi-Fi base station

WDS (802.11g)

A Wireless Distribution System (WDS) is the method used to extend the range of AirPort Extreme 802.11a/b/g and AirPort Express 802.11a/b/g Wi-Fi base stations. WDS is supported by AirPort Utility 5.5.2 or earlier.

Range Extenders For Mac Computers

WDS allows you to set up each Wi-Fi base station in one of three ways:

➊ WDS main (Primary Wi-Fi base station)
➋ WDS relay
➌ WDS remote

A WDS main base station ➊ is connected to the Internet and shares its connection with WDS relay and WDS remote base stations.

A WDS relay base station ➋ shares the main base station’s Internet connection and will also relay the connection to WDS remote base stations.

A WDS remote base station ➌ simply shares the WDS main base station’s Internet connection either directly if in direct range, or through a WDS relay.

All three base station configurations (WDS main, WDS remote, and WDS relay) can share the WDS main Wi-Fi base station’s Internet connection with client computers wirelessly, or through an Ethernet connection if the client computers are connected to the base station by Ethernet.

When you set up base stations in a WDS, you need to know the AirPort ID of each base station. The AirPort ID, also known as the Media Access Controller (MAC) address, is printed on the label on the bottom of the AirPort Extreme Base Station next to the AirPort symbol, and on the power adapter side of the AirPort Express Base Station.

Note: As a relay, the Wi-Fi base station must receive the data from one Wi-Fi base station, repackage it, send it to the other Wi-Fi base station, and vice versa. This method effectively cuts the throughput by more than half. An 802.11a/b/g Wi-Fi base station should only be used in this manner in areas where there is no other option, and where higher throughput is not essential.
