In Germany, the network technology is called WLAN, while the term Wi-Fi is used in English-speaking countries. The 802.11 numeric sequence indicates the radio standard, the letter combination behind the version. In 2018, the combination of numbers and letters was replaced with the abbreviation "Wi-Fi" plus a number. Wi-Fi-4 is 802.11n compliant, Wi-Fi-5 is 802.11ac, the successor to current 802.11ax is called Wi-Fi-6. The more up-to-date the standard, the higher the possible data transmission rates in the WLAN.

What is a WiFi Repeater?

WiFi repeaters

Commercially available WiFi repeaters are electronic devices that pick up and forward signals from a WiFi router. It increases the range of the WiFi signal. At the same time, repeaters can have a positive effect on signal stability. Alternatively, WiFi repeater is referred to as WiFi booster, signal booster, WiFi booster, or range extender. In short, the repeater strengthens the home network/WiFi network coverage or closes dead spots and provides another WiFi access point.

Important to know: The German term WLAN amplifier is not entirely accurate. Because WiFi repeater can't improve WiFi connection or performance, but just forwarding it slightly improved.

What is WiFi and how does it work?

To understand how WiFi repeaters work, it's a good idea to take a look at how WiFi technology works. WLAN stands for Wireless Local Area Network or in German a wireless local radio network. This is a radio connection that allows wireless Internet access. WLAN networks have been around since the late 1990s. Previously, computers could only be connected via a LAN cable connected to a worldwide data network.

WiFi signals can be sent over different channels and on different frequencies. For connection between transmitter and receiver, both devices must use the same channel on the same frequency. There are two frequency bands in Europe – 2.4 gigahertz (GHz) and 5 gigahertz (GHz). Both use different channels. 2.4 gigahertz (GHz) uses channels 1 through 13 and 5 gigahertz (GHz) uses channels 36 through 64 and 100 through 140.

The data rate - that is, the speed - of the WLAN connection depends on the WLAN standard being used. The 802.11g standard is used for a long time, up to 54 megabits are transmitted per second. The next 802.11n standard allows data rates of up to 150 megabits per second. With the newer 802.11a standard, up to 1,300 megabits per second is possible. For comparison: 8 megabits (Mbit) is 1 megabyte. So 1,300 megabits is 162.5 megabytes per second.

The range of a WiFi signal on a network is influenced by many factors, such as physical barriers such as furniture, wall materials, and wall thickness. Connection problems are common in older buildings if the router is in a different room from the end device.

How do WiFi repeaters work?

The technical function of a WiFi repeater is very complex. Simply put, a WiFi repeater is a combination of a WiFi client – ​​i.e. the receiving device – and a WiFi router. The repeater logs into an existing WLAN home network and creates its own radio cell on the radio network that other clients can access. A WLAN repeater acts as a sort of mediator between two remote WLAN devices. The range varies from model to model. Depending on the WiFi repeater and structural conditions, WiFi signals may be relayed to devices 10 to 200 meters away.

With multiple WiFi repeaters, data rates are halved during the range increase process. If you have a slow internet connection, you should make sure that this is not the case on the device you are considering.

Positive side effect: When the WiFi signal reaches the repeater, it is equalized before being forwarded. As a result, the signal is passed on without much loss. This can also have a positive effect on the stability of the WLAN connection. This means that the risk of normal WiFi interference due to sources of interference associated with short-term data rate drops can be reduced by using a WiFi repeater.

Unlike wireless routers, no manual setup is required on most extenders. After connection to the socket, signal adaptation is carried out completely automatically by the device. This works because the extender uses the same SSID as the router by default. SSID stands for Service Set Identifier and indicates the name of each WLAN radio network. If you want to connect the device to the router via WLAN, you must use the correct access point, which can be identified by the SSID name.

Possible uses – when is it worth using a WiFi repeater?

WiFi repeaters

Contrary to what is often assumed, WiFi repeaters cannot speed up slow internet connections. The repeater does not increase the speed of the Internet connection, it only increases the range. Therefore, purchasing a WLAN repeater is always beneficial when wireless Internet usage does not work due to a weak WLAN signal - i.e. insufficient coverage. This can happen in many situations, such as:
  • In the park
  • In the attic, in the garage or in the basement
  • In an apartment with several floors
  • In old buildings and apartments with thick or metal-reinforced walls
  • In an apartment, office or factory with a large area
Most desktop PCs have a wireless card that allows you to open a wireless hotspot. This allows wireless devices to access the computer's Internet connection independently of the wireless router. The problem with this method is the fact that the range of such a hotspot is often only a few meters.

What are the advantages and disadvantages of WiFi repeaters?

The main advantage of a WiFi repeater is that it allows wireless Internet access over a large area with just one router. The WiFi repeater is compact, takes up little space and is inexpensive. Another advantage: you can equalize the WLAN signal and help ensure it remains stable over the long term.

The biggest disadvantage lies in the fact that multiple WiFi repeaters can negatively affect surfing speed and, in the worst case, cut it in half. Also worth mentioning: WLAN repeaters can't increase surfing speed. Many people buy repeaters for this purpose and are then disappointed when their slow Internet speed remains unchanged.

  • Improve signal strength - better WiFi coverage
  • Compact design
  • Support WiFi connection stability
  • Can only increase WiFi signal strength
  • Surfing speed can be halved
  • Unable to increase browsing speed
What types of WiFi repeaters are there?

WiFi repeaters

There is no type of WiFi repeater. However, based on their nature, devices can be divided into two categories. This includes:
  1. WLAN repeater without LAN connection
  2. WLAN repeater with LAN connection
WLAN repeater without LAN connection

A WLAN router without a LAN connection is the device most of which have been described in this product overview so far. They pick up the signal from the wireless router, equalize it and pass it on to the receiving device.

WLAN repeater with LAN connection

A WLAN repeater with a LAN connection works like an extension cable. The repeaters are positioned as needed and connect wirelessly to the WLAN router. Now the repeater can be connected to other devices via a LAN cable - for example a desktop PC, television, or game console. This makes it possible to go online with devices that do not support WLAN without a direct connection to the router. The repeater then functions as a "bridge", which is why it is often referred to as a "LAN bridge".

A WLAN repeater with a LAN connection makes sense, for example, if the router is on a different floor from the target device - for example, the TV in the living room is downstairs and the router in the study is upstairs. Laying cables across multiple floors takes a lot of effort. With a WiFi repeater, the problem can be solved in a few minutes.

How much does a WiFi repeater cost?

WLAN repeaters are in a manageable price range. The cost depends on the performance of the repeater, the frequency band used and the technology used. Cheap WLAN repeaters are readily available for low double-digit counts. In the mid-range price range there are devices for the mid-to-higher double-digit counts. In the upper price range, triple digit investment may be required. The following costs can be expected when purchasing a WiFi repeater.
  • WiFi repeater in lower price range: 20 to $50
  • Mid-range Wi-Fi repeaters: 50 to $75
  • WLAN repeaters in the top price range: from $75
Internet versus specialist stores: where can I buy a WiFi repeater?

Outside of the Internet, WiFi repeaters can be found almost exclusively in computer and electronics stores. The advantage of local trading is the opportunity to get personal advice. In addition, buying from local retailers is often impractical. The range of available models is usually limited, as is consumers' ability to compare devices. In the worst case, it will take a lot of time to visit several shops to find a suitable WiFi repeater.

The internet offers better conditions to buy a good WiFi repeater quickly and with less effort. Not only are almost all the currently available models available here, but there are also good conditions for obtaining comprehensive information and comparing each device precisely with each other. As soon as the best WiFi repeater is found, orders can be placed easily and quickly from home. In the end, the advantages of the Internet outweigh the disadvantages. That doesn't mean that you can't find good WiFi repeaters at local stores with more effort.

WiFi repeater buying advice: What to consider when buying a WiFi repeater?

WiFi repeaters

Interested parties should pay attention to the following criteria before making a purchase:
  1. Setting function
  2. WLAN standard and frequency band
  3. Dual band and MU-MIMO capability
  4. LAN port or bridge function
  5. Additional equipment/techniques
  6. WiFi Encryption
  7. WLAN system uniformity
  8. Size

The first thing to do is determine how the WiFi repeater should be set up. This is an important decision, especially for a technical layman. WLAN routers and repeaters can be connected to each other using two different systems:
  • WPS - Wi-Fi Protected Setup - Wireless routers and repeaters are equipped with a WPS button. First, the button on the router is pressed. The WPS button on the repeater must then be pressed within a few minutes, manufacturers often specify two minutes. After that, automatic connection. This function is often referred to as PBC or Push Button Configuration.
  • PIN code – Routers and repeaters can be paired with each other using an eight-digit PIN code. Since both devices usually don't have displays, this has to be done manually in a web browser. In practice, this can prove to be a hassle.

Manufacturers often do not provide precise information on how to set up their WiFi repeaters. If there is no WPS button, it can be assumed that the repeater can only be set using a PIN code.

Frequency bands and standard WLAN devices

WLAN backward compatible. That means a 2.4 gigahertz device can be paired with a 5 gigahertz router. Surfing speed is reduced to the maximum data rate of devices with lower frequency bands. In order for full data rates to reach the target device, it is therefore important to ensure that the WLAN router and WLAN repeater work on the same frequency band.

Manufacturers often state the maximum data rate a repeater can achieve under optimal conditions. Buyers should also pay attention to the properties of the end device – i.e. the device that is supposed to receive the WiFi signal from the repeater. If the target device operates in the 2.4 gigahertz band, there is no point in having routers and repeaters operate in the 5 gigahertz band.

There are several WLAN standards with different data rates in the frequency band. It should also be ensured that all devices are compatible with each other. The WLAN standard is identified with the IEEE 802.11 designation. The following distribution applies to the 2.4 gigahertz band:
  • 802.11 with 1 to 2 megabits per second
  • 802.11.b at 6 megabits per second
  • 802.11.g at 20 megabits per second
  • 802.11.n at 170 megabits per second
The following applies to the 5 gigahertz band:
  • 802.11.a and h at 20 megabits per second
  • 802.11.n at 170 megabits per second
  • at 1,300 megabits per second
The WiFi repeater with tri-band technology belongs to the fastest devices in the market. They have three transmitter and receiver units and use the 2.4 and 5 gigahertz bands simultaneously. Two units each use the 5 gigahertz band and one unit each uses the 2.4 gigahertz band. Tri-band technology can be found almost exclusively in devices in the higher price range.

Dual-band and MU-MIMO function

If you want to avoid reducing your surfing speed, you should make sure that a new WiFi repeater having dual-band functionality is provided. A repeater with dual-band functionality has two transmitter and receiver units. It receives the signal from the router through one unit and sends it to the target device through another unit. It can also be used as a crossband repeat function which is designated to reduce losses in data rates.

In order to be able to connect multiple devices to the Internet at the same time via a WLAN repeater, the MU-MIMO function is required. This allows the repeater to communicate with multiple devices at the same time. This reduces device waiting time for signal and thus optimizes network/home network speed.

LAN port or bridge function

To connect non-WLAN-enabled devices to a repeater, a LAN connection is required - often referred to by manufacturers as a bridge function. The number of LAN ports must be taken into account here. While many devices are limited to a single LAN port, others offer up to five connection options for a LAN cable. The more LAN ports a WiFi repeater has, the larger it will be. Prior to purchasing, interested parties should get an idea of ​​whether and how many devices they can connect to via a LAN cable want to connect to the repeater.

Additional equipment/technology

WLAN repeaters can be equipped with a variety of additional technologies and functions that enhance ease of use and support WLAN signals. This includes:
  • LED light: Most WLAN repeaters are equipped with LED lights that indicate, for example, the frequency range used and the operational readiness of the device. Less common but useful are LED lights that show signal strength -- called signal strength indicators. This makes it easier to find a good position for the WiFi repeater.
  • Mesh system support: WiFi repeater with mesh system support can work in network with other repeaters. This allows a larger area to be covered by the WLAN signal.
  • Access Point Steering: The network automatically detects whether a router or repeater is providing a better signal. The network establishes a connection to the appropriate end device.
  • DFS function: DFS function helps maximum speed. If routers and repeaters are equipped with it, they will recognize all available 5.0 gigahertz channels and automatically avoid channels already used by other devices.
  • USB port: A USB port allows a wireless repeater to connect an external hard drive, scanner, printer, or other device to the Internet via a cable.
  • Audio interface: The analog audio interface on the WLAN repeater makes it possible to connect the hi-fi system to a WLAN radio network and control it via WLAN. In this way, the home stereo system can be controlled wirelessly via a computer.
WiFi Encryption

WLAN encryption is used to protect wireless data transmissions from unwanted access. There are also four encryption protocols for WLAN repeaters to use:
  • WEP - Privacy Equals Wired
  • WPA - Protected Wi-Fi Access
  • WPA2 - Wi-Fi Protected Access 2
  • WPA3 - Wi-Fi Protected Access 3
A repeater that only works with WEP is not recommended. It is an encryption protocol with many weak points that is no longer considered up-to-date. WLAN repeaters should at least be secured with WPA. The WPA2 encryption protocol is better because it uses a more modern algorithm and offers higher security standards. The latest standard is WPA3. Most repeaters work with WPA or WPA2.

Power supply type

A WLAN repeater with an integrated power plug plugs directly into the socket. Alternatively, there is a standing device that is supplied with power via a power cord. The advantage of a WLAN repeater with an integrated power strip is that it does not require a parking space. Downside: It's more difficult to find a suitable place because the repeater is tied to the position of the socket. This loss can be compensated by using an extension cord. Another disadvantage: Depending on the design, repeaters can block adjacent slots. WLAN repeaters with external power are usually more expensive, but can be set up more flexibly and don't block sockets. Looking at consumption in kilowatt hours makes sense before you buy.


It is advisable to get an idea of ​​where a new WiFi repeater can be placed before you buy it. Action must be taken in these places. This way, interested parties can consider the dimensions of the repeater when purchasing and ensure that there is enough space. This is especially important for repeaters that can be plugged directly into a socket.

What to consider when setting up a WiFi repeater?

To ensure the best signal transmission, it is often recommended to position the extender halfway between the router and the target device. As long as the router and repeater are in line of sight, good reception is usually guaranteed. To avoid interference, there should be no large metal devices near the router or repeater - such as a refrigerator or microwave oven. After positioning and running the repeater, reception should be tested. When in doubt, the device should be repositioned as often as necessary to achieve the desired signal strength.

WiFi repeater with signal strength indicator can help find a suitable place quickly.

Frequently asked questions about WiFi repeaters

WiFi repeaters

Which wifi repeater is the best?

There is no such thing as the best WiFi repeater. Each buyer has different requirements and must consider aspects such as different data rates, target devices, and the distance to be bridged to their place. No device is the same for all interested parties. If you consider all the tips in this guide, you have a good chance of finding the best WiFi repeater for your personal needs.

Are WiFi Repeaters Dangerous?

According to the current state of research, scientists assume that the radiation emitted by WLAN routers and repeaters is harmless. Most measurements come from the Federal Office for Radiation Protection. Radiation exposure from electronic devices is determined by a specific absorption rate – abbreviated as SAR. The SAR level is given in watts per kilogram. Value refers to how much the body is heated by electromagnetic energy. For comparison: smartphones and tablets are rated at 1 watt per kilogram. WLAN routers and repeaters have power between 0.1 and 0.5 watts per kilogram. Values ​​of more than 2 watts per kilogram are considered questionable.

What is the difference between a WiFi booster and a WiFi repeater?

WiFi booster and repeater are synonymous terms that refer to the same device. In this context, amplification simply means that the WLAN signal is amplified, i.e. the range is increased. No device can boost Internet connection and make it faster at the same time.

Can I use multiple WiFi repeaters at the same time?

Yes, theoretically up to 254 WiFi repeaters can be connected in series. It should be noted that surfing speed decreases with each enhancement. If you want to connect multiple repeaters to each other, you should look for mesh support and dual-band functionality respect, think highly. In this way, speed loss can be reduced.

Is it a wireless repeater with all routers? compatible?

No, WiFi repeaters are not compatible with all routers. In general, it can be assumed that support for current devices - released in the last 3 to 5 years - is provided. If you want to be on the safe side, you should pay attention to the information provided by the manufacturer. Manufacturer's specifications are often not very precise. Most of the time it says "compatible with all routers" or "compatible with standard WiFi routers". Looking at testimonials from other users can provide clarity.


What do you think? Have you got a suitable signal amplifier? A WiFi repeater will make your work and activities easier, whether at home, office, park, or the place of business that you are starting.

Therefore, you need to choose the best WiFi repeaters. Read carefully each point we have explained. Next, compare the advantages of each product. Don't forget to adjust it to the budget you have prepared. Hope this review helps you.
