Configuring an Edimax Extender for the 5 GHz Band

An Edimax wireless extender can improve coverage in rooms where a router’s signal becomes weak, without forcing every device onto the slower or busier 2.4 GHz band. A 5 GHz-only arrangement is useful when you want higher local speeds for streaming, video calls, gaming or large file transfers and your compatible devices are within reasonable range of the extender.

The process usually involves connecting to the Edimax setup page, selecting the main router’s 5 GHz network, entering its wireless password and choosing how the extended network will appear. Menu names differ between Edimax models, including RE-series range extenders and devices that support universal repeater or access-point modes, so use the labels shown by your hardware.

Choose 5 GHz Extension Mode

A 5 GHz-only extension means the extender uses and broadcasts the 5 GHz frequency, while its 2.4 GHz radio is disabled or left unused. This prevents phones, printers and smart-home equipment from being placed on the extended 2.4 GHz network. It also avoids creating an unnecessary second network when your priority is fast, short-range wireless coverage.

This arrangement works best for recent laptops, tablets, televisions, streaming boxes and gaming consoles. Many older printers, security cameras, smart plugs and irrigation controllers support 2.4 GHz only. They will not connect to a 5 GHz-only network, so retain the primary router’s 2.4 GHz service if those devices still need wireless access.

Edimax firmware may describe the relevant setting as “5 GHz Repeater”, “Universal Repeater”, “Range Extender”, “Wireless Bridge” or “Access Point”. Repeater mode receives Wi-Fi from the existing router and rebroadcasts it wirelessly. Access-point mode normally uses an Ethernet cable between the router and extender, which can provide more consistent performance because the extender does not have to use the same radio for both the wireless backhaul and client traffic.

Check Compatibility and Placement

Confirm that the Edimax model has a 5 GHz radio and supports the operating mode you intend to use. A product marked dual-band generally supports both 2.4 GHz and 5 GHz, but the firmware may still offer separate controls for each band. Check the label on the device, its quick installation guide or the model-specific support page before changing settings.

Place the extender between the router and the area with poor coverage, rather than inside the dead zone. It needs a stable 5 GHz connection to the main router before it can repeat that signal. In a typical Melbourne or Sydney apartment, a hallway shelf may work better than a room behind several concrete walls. In a larger Brisbane or Perth home, test locations near the centre of the floor can reduce the distance between the router and the far bedroom.

Avoid positioning the unit inside a cabinet, behind a television or beside large metal appliances. Thick masonry, foil-backed insulation, mirrors and some reinforced walls reduce 5 GHz range. Because 5 GHz travels less effectively through obstacles than 2.4 GHz, the best location may appear close to the router even when the weak-signal room is much farther away.

Prepare These Details Before Setup

The Edimax model number and current firmware version.
The main router’s 5 GHz network name and wireless password.
A phone or laptop with Wi-Fi and a web browser.
The Edimax default address, often shown in its manual or on its label.
A power point near the router for the initial configuration.

Open the Edimax Setup Page

Connect your computer or phone to the extender before attempting configuration. During first-time setup, the Edimax unit may broadcast a temporary network with a name similar to its model number. Some models also provide an Ethernet port, allowing a laptop to connect directly with a network cable. Disable mobile data temporarily on a phone if it keeps switching away from the extender’s temporary Wi-Fi.

Open a browser and enter the setup address printed in the Edimax documentation. Depending on the model and operating mode, this may be an Edimax-specific web address or a private IP address such as 192.168.2.1 or 192.168.9.1. The exact address is not universal. If the page does not load, check that the device is powered on and that your computer has received a connection from the extender.

The setup wizard may request an administrator password before showing wireless options. This password controls the configuration page and may be separate from the Wi-Fi password used by devices. Replace any default administrator credentials when the firmware allows it, and record the new details in a secure password manager.

Australian households often use an NBN-supplied modem-router from providers such as Telstra, Optus or TPG, sometimes with a separate mesh system connected behind it. Identify which device actually broadcasts the 5 GHz network before beginning. If the Edimax extender is connected to a mesh satellite instead of the main router, the available network name and security settings may differ.

Select the Main 5 GHz Network

Choose the repeater or range-extender wizard and scan for nearby wireless networks. The results normally display separate entries for 2.4 GHz and 5 GHz, although a router using band steering may show one combined network name. Select the entry that is clearly associated with the 5 GHz radio. Signal strength should be good at the extender’s temporary location.

If the router uses one name for both bands, look for a frequency indicator in the scan results or temporarily give the bands distinct names in the router settings. For example, a household might use “HomeNet” for 2.4 GHz and “HomeNet-5G” for 5 GHz. The “5G” suffix here means 5 GHz Wi-Fi, not a mobile phone network. After configuration, you can retain separate names or restore the router’s preferred naming scheme.

Enter the main router’s wireless password exactly as configured. Passwords are case-sensitive, and an extra space can cause the connection to fail. Use WPA2-Personal or WPA3-Personal where the Edimax model supports it and where the main router uses the same compatible security method. Older extenders may not join a WPA3-only network; selecting a mixed WPA2/WPA3 mode on the router can improve compatibility.

Some Australian NBN routers automatically select DFS channels for 5 GHz operation. These channels may be legal and useful under Australian Communications and Media Authority rules, but older extender firmware can have difficulty detecting or repeating them. If the 5 GHz network does not appear during scanning, temporarily select a common non-DFS channel in the router, such as 36, 40, 44 or 48, then scan again.

Configure the Extended Wireless Network

When the wizard asks for the extended network name, you can copy the main 5 GHz SSID or create a distinct name. A separate name such as “HomeNet-5G-EXT” makes it clear when a device is connected through the extender. It also simplifies testing because you can manually connect a laptop or phone to the extended signal rather than relying on automatic roaming.

Using the same SSID and password can make movement around the home more convenient. However, an extender is not a full mesh system, and devices may remain attached to the weaker access point until they decide to roam. Separate names provide more control, especially when you need to confirm that a television in a back room is using the Edimax unit.

Disable the 2.4 GHz extended network if the firmware provides separate radio controls. The option may appear under “Wireless Settings”, “Extended Wireless Settings”, “Advanced” or a band selector. Turn off the 2.4 GHz SSID rather than disabling the entire wireless service, and confirm that the 5 GHz SSID remains enabled.

If the interface does not offer a 5 GHz-only option, do not assume that renaming the network has disabled the other band. Some Edimax extenders require separate configuration for each radio, while others repeat both bands automatically. In that case, look for a wireless schedule, radio enable switch or operating-mode limitation in the manual.

Wireless Settings Worth Recording

The extended 5 GHz network name, or SSID.
The selected security mode and wireless password.
The channel width, such as 20, 40 or 80 MHz.
The extender’s final management address.
Whether the 2.4 GHz radio is disabled or still active.

Apply Security and Verify Performance

Save or apply the configuration and allow the extender to restart. During this process, the temporary setup network may disappear. Reconnect to the new 5 GHz extended network using the password entered during setup. If the extender has moved to its final location, wait until its status light indicates a connection to the main router.

Test with a device that supports 5 GHz and stand in the room where coverage was previously poor. Check the connection details to confirm that the device is using the Edimax SSID and not the original router network. A speed test can show whether performance has improved, but test at different times because evening congestion can affect NBN streaming and internet results independently of the Wi-Fi link.

A wireless extender can improve signal strength without increasing the speed of the internet plan. In wireless repeater mode, traffic often travels from the client to the extender and then from the extender to the router over the same general radio resources. A strong signal is helpful, but an Ethernet-connected access point usually delivers better throughput where cabling is practical.

Check local network access as well as internet access. Open a website, play a high-definition stream and access a printer or media device if required. If the extender connects to the router but clients receive no internet, verify that the Edimax is in repeater or access-point mode rather than router mode, and ensure that DHCP is not being provided by two devices.

Troubleshoot 5 GHz Connection Problems

If the main 5 GHz network is missing from the scan, move the Edimax closer to the router and scan again. Confirm that 5 GHz is enabled on the router and that the SSID is visible. Temporarily change the router to a non-DFS channel and use a compatible channel width. A channel width of 20 or 40 MHz can be a useful stability test in a crowded apartment block, even though 80 MHz may offer higher peak speeds.

When the extender accepts the password but fails to connect, check the router’s security mode, access-control list and maximum client settings. Remove any MAC filtering rule that blocks the Edimax. Re-enter the password manually rather than relying on a saved browser value. If the router combines 2.4 GHz and 5 GHz under one SSID, temporarily split the names so the extender can be directed clearly to the correct band.

Frequent dropouts usually indicate distance, interference, channel changes or a marginal backhaul signal. Move the extender one room closer to the router and test again. Keep it away from cordless phone bases, Bluetooth hubs, USB 3.0 storage devices and large appliances. In busy areas such as central Sydney or Melbourne, neighbouring networks can occupy many channels, so a narrower channel width may produce a steadier connection.

A reset is appropriate when an old configuration continues to interfere. Hold the reset button for the period specified in the Edimax manual, wait for the unit to restart and repeat the setup from its temporary network. Record the existing settings before resetting, because the administrator address, SSID and operating mode will return to their defaults.

Confirm the Final Band-Specific Setup

Review the wireless status page after the extender has been running for several minutes. It should show the main router’s 5 GHz network as the uplink or source connection and the extended 5 GHz network as enabled. The 2.4 GHz extended radio should be listed as disabled if your goal is to extend only 5 GHz.

Walk through the home with a phone or laptop and check connection behaviour near the router, beside the extender and in the target room. Devices may switch between the original router and the extender when the names match. For a clear test, temporarily forget the main network on the device and connect only to the Edimax extended SSID.

Remember that 5 GHz is designed for higher speeds over shorter distances, while 2.4 GHz is more forgiving through walls. A 5 GHz-only extension is therefore a targeted solution rather than a universal replacement for dual-band coverage. Keep the router’s original 2.4 GHz network available for older equipment and low-bandwidth devices that cannot use the extended band.

When the configuration is stable, update the Edimax firmware if a suitable release is available for the exact model and Australian region. Firmware updates can improve channel compatibility and security, but apply them only through the official management interface or documentation for that device. Do not interrupt power during the update.

Final Verification Checklist

The extender’s source connection is the router’s 5 GHz network.
The extended SSID appears on a compatible phone or laptop.
The extended 2.4 GHz radio is disabled, if supported by the model.
The signal remains stable from the chosen placement.
Internet and local network access work from the target room.
The administrator password is no longer the factory default.

Open the Edimax status page from the target room, confirm the 5 GHz uplink and extended SSID, then run one local and one internet connection test before leaving the extender in its permanent position.
