What You'll Learn
Manually changing channels on Airport Extreme
If you have a "round" AirPort Extreme, you will need to download and install AirPort Utility 5.6 for Mac OS X Lion. You can keep both AirPort Utility 5.6 and 6.0 on your Mac.
To manually change the channel on your AirPort Extreme, follow these steps:
- Open Finder > Applications > Utilities > AirPort Utility.
- Click on the AirPort Extreme icon, then click Edit.
- Edit the 2.4 GHz Channel and 5 GHz Channel by clicking on the selection box to change the setting from Automatic to a channel of your choice.
- Click Save, then click Update and allow 25-30 seconds for the AirPort Extreme to restart.
Please note that the available channels depend on your region. For example, channels 12 and 13 are not allowed in North America, and Apple does not support the use of higher-numbered channels on European versions of AirPort Extreme.
Manually changing the channel may help improve your Wi-Fi performance, especially if there are many other wireless networks around you that may be causing interference. However, keep in mind that other wireless routers are constantly changing channels as well, so you may need to experiment with different channels over time.

Improving Wi-Fi speed
Next, connect the Ethernet cable to the AirPort Extreme and check its settings on the AirPort Utility on your Mac. Open the utility and click on the AirPort Extreme, then click Edit. Click the Wireless tab and ensure the setting for Network Mode is set to "Create a wireless network". Once you have checked the settings, run some speed checks with the Wi-Fi turned back on and your Mac in close proximity to the AirPort.
If you are extending your AirPort Extreme with another base station, your network will lose around 50% of its bandwidth. To avoid this, use wired connections between the base stations. Additionally, when using an AirPort Express to extend the range of an AirPort Extreme, ensure that they are not using the same channel, as this can cause issues.
If you are experiencing interference from other nearby networks, try to locate your wireless router away from outside walls or windows to help shield it from other signals. You can also try changing the channel that your AirPort Extreme uses. The default setting is usually automatic, where the base station will scan and select the best available channel. However, you can manually select a channel by opening the AirPort Utility and clicking on the AirPort Extreme, then Edit, and selecting the desired channel.
Other methods to improve Wi-Fi speed include ensuring you have strong encryption and a secure password for your Wi-Fi network, as well as regularly restarting your AirPort Extreme, especially if you live in an area with many other wireless networks.

Using a second router
If you're using two Airport Extremes, you can set them up to use the same channel or different channels. If you want devices to roam and connect to the AirPort with the best signal, you'll need to let them use the same channel. If you assign different SSIDs to each AirPort, you will have to log on to a different network when you move a WiFi device closer to another AirPort access point.
If you want to use different channels, you can set up your second Airport Extreme to create a wireless network with the same name and password as the first one, but with a 2.4 GHz channel chosen so as to be separated from the first one's channel by three empty channels. For example, the first airport could be on channel 5, and the second on channel 9. For 5 GHz channels, just choose two different ones (5 GHz channels don't overlap as 2.4 GHz do).
You can also set one or two routers manually and let the others use auto. If you use the Automatic setting, the AirPort will scan and select the best channel to use. However, it will swap channels hourly as it continues to scan, as well as when other wireless routers scan and change channels.
If you want to change the wireless channel on your AirPort Extreme manually, open Finder > Applications > Utilities > AirPort Utility. Click on the AirPort Extreme, then click Edit in the smaller window that appears. The setting for the 2.4 GHz Channel is here. The setting should be on Automatic now, but you can change it to select a channel manually. However, this can be a guessing game, as you won't know which channel to choose, and even if you find a good channel, you will likely have to change it again soon as other routers are constantly changing their channels.

Using a Wi-Fi extender
You can use an AirPort Extreme as a Wi-Fi extender to boost your wireless network. To do this, you need to connect your AirPort Extreme to your primary router. You can do this either by using a wired Ethernet cable or by connecting wirelessly.
If you are using a Mac, you can find the AirPort Utility program by clicking "Go," then "Applications," and choosing the "Utilities" folder. On a Windows PC, you can find it in the "Start Menu" by clicking "Programs" and then "AirPort."
Once you have opened the AirPort Utility, follow these steps:
- Connect to your primary router using the "Base Station Chooser" in the setup program.
- Click "Manual Setup" and enter your password if prompted.
- Click "Airport," then "Wireless," and click "Create a Wireless Network."
- Check the box that says "Allow This Network to Be Extended" and enter or confirm your desired network name.
- If you want to secure your network, click "Wireless Security" and select a security type, such as "WPA2 Personal." Choose a password that meets the specified requirements.
- Under "Radio Channel Selection," click "Automatic" and then click "Update."
- Now, connect to your AirPort Extreme (secondary router) using the "Base Station Chooser."
- Disconnect from the secondary router and connect to the primary router.
- In the AirPort Utility, set "Connection Sharing" to "Off (Bridge Mode)." This ensures that the secondary router will pass traffic to the primary router.
- Ensure that the network name, security settings, and password are the same on both the primary and secondary routers.
- Click "Update" to save the changes.
If you are using a wired Ethernet connection between the routers, you can stop here. If you are using a wireless connection between the routers, you may need to take additional steps, such as ensuring that the secondary router is within good reach of the existing Wi-Fi network.
Additionally, note that the AirPort Extreme will automatically scan and select the best available wireless channel. However, if you want to manually change the channel, you can do so through the AirPort Utility.

Using a wired connection
If you are using a wired connection with your Airport Extreme, you may still be able to change the wireless channel. However, it's important to note that the specific steps may vary depending on your operating system and the version of your Airport Extreme.
- Ensure that you have the latest version of Airport Utility installed on your computer. In some cases, older versions of Airport Utility may not be compatible with your Airport Extreme, so updating to the latest version is recommended.
- Open Airport Utility on your computer. You can usually find it in the Utilities folder within the Applications directory.
- Connect your computer to the Airport Extreme using an Ethernet cable. This will ensure a direct wired connection between your computer and the router.
- Launch Airport Utility and click on your Airport Extreme. You may need to click on "Edit" or "Wireless" to access the settings.
- Look for the Wireless Options or Wireless Settings. This is where you will find the settings for the 2.4 GHz and 5 GHz wireless channels.
- Change the channel selection from "'Automatic' to "Manual." By default, Airport Extreme is set to "Automatic," which allows it to scan and select the best available channel. However, in congested areas with many wireless networks, manually selecting a channel may provide better performance.
- Select the desired channel for the 2.4 GHz and/or 5 GHz band. The available channels may vary depending on your region due to local regulations. For example, in North America, only channels 1-11 are available, while in other regions, additional channels like 12 and 13 may be usable.
- Save the changes and restart your Airport Extreme. Once you've selected the desired channel(s), apply the changes and restart your router for the new settings to take effect.
It's worth noting that manually selecting a wireless channel can be a bit of a guessing game, as other nearby routers may also be changing their channels frequently. This may result in you needing to change your channel again in the future to maintain optimal performance. Additionally, cordless phones and other wireless devices can also cause interference, so keep them away from your Airport Extreme and computers if possible.
