Authored by: Support.com Tech Pro Team

1. Introduction

In This Guide

You'll Learn How To:

Resolve basic problems you may encounter with your ASUS RP-AC55 Range Extender.

Before We Begin:

Be near your Range Extender.
Be prepared to test both your connection to your home's Wi-Fi network and your Range Extender's network.

2. Check Devices Off Range Extender

Before checking your range extender at all, it's best to make sure the rest of your home network is functioning properly.

Test your connection using a computer, smartphone, or tablet that is not connected to the range extender. Preferably, it's best to test using a device that is directly connected to your router via Ethernet cable. If this is not possible, use a device that's connected wirelessly to your home's Wi-Fi network.

A home computer that is hard-wired to your router via Ethernet is ideal for this test. Otherwise, make sure the wireless device you're testing with isn't connected to the range extender's Wi-Fi network (this usually contains "_EXT" in the network name).

4. Problem Check

Depending on the problem you're having, different steps may need to be taken to help solve them.

Can't Browse

You can connect your device(s) to your range extender, but you're unable to bring up a web page, email, or other services on the Internet.

Slow Connection

You're able to connect your device(s) to your Range Extender, and you're able to bring up web pages, email, and other services, but the connection seems slow.

No Connection

You're unable to find your Range Extender's Wi-Fi network to connect your device(s) to.

Poor Connection Between Range Extender and Router

The connection between your Range Extender and your wireless router has weak or poor signal, making the connection slow.

Won't Turn On

The Range Extender won't turn on at all.

5. Reduce Wireless Interference

Wireless signal interference can cause performance issues such as slow or intermittent connections and even complete disconnects. This type of interference can be caused by the presence of:

Electromagnetic fields created by other electronic devices such as: Wi-Fi or Bluetooth capable devices, cordless phones, baby monitors, remote controlled toys, microwave ovens, seasonal lighting, or even garage door openers.
Structural materials in walls, floors, furnishings or other large objects. The potential for structural materials in your home to absorb wireless signal and cause signal loss or undesirable behavior is as follows:

Interference PotentialType of MaterialLowSynthetic material, wood, glassMediumBrick, marble, waterHighConcrete, plasterVery HighMetal

To Reduce Wireless Signal Interference Caused by Other Electronic Devices:

Temporarily turn off or power down any of the devices listed above, and test your connection.
If the issue persists, try physically moving the device having connection problems away from any device(s) that could cause interference, and re-test.

To Reduce Wireless Signal Interference Caused by Other Objects or Structures:

Relocate the device having connection problems away from any obstacles, and test the connection.
If your range extender or the device having connection problems is set up inside of a cabinet, closet, or other type of enclosure, consider relocating them.

Range extenders are designed to be relocated easily. For this reason, finding and testing alternative locations in your home that may provide better and more reliable signal coverage and be less prone to wireless interference may be the best option.

6. Location

Finding the most optimal location for your Range Extender in your home is important for both maximizing your signal range and wireless coverage. Your Range Extender has a built-in meter to help you determine where this might be.

Move Closer

If the left of the two lights is on, that indicates you need to move the Range Extender closer to your router, so it gets a better signal.

Good Location

When no lights are on for the range indicator, your Range Extender is in a good location.

Move Away

If the right of the two lights is on, that indicates that you need to move the Range Extender farther away from your router, to avoid an overlap of signal that could cause problems.

You can move your Range Extender from outlet to outlet using the meter depicted above as a guide for selecting locations that will provide the best wireless performance in your home.

In general, you want your Range Extender at least six feet away from your router. At most, you want it half-way between where your router is, and where you want the signal to reach. Finding and testing multiple locations may be necessary if wireless interference is a factor within your home.

7. Power Cycle

Turn off your range extender.
