Important considerations


  • Increase Range: Wi-Fi extenders can be used to expand the range of an existing Wi-Fi network, allowing for better coverage in areas that would otherwise be out of reach.
  • Eliminate Dead Spots: Wi-Fi extenders can be used to eliminate dead spots in your home or office by boosting the signal in areas where it would otherwise be weak.
  • Increase Speed: Wi-Fi extenders can be used to increase the speed of an existing Wi-Fi network, allowing for faster data transfer speeds and improved streaming performance.
  • Reduce Interference: Wi-Fi extenders can be used to reduce interference from nearby networks, allowing for a more consistent and reliable connection.


  • Interference: Wi-Fi extenders can cause interference with other wireless devices in close proximity.
  • Cost: Wi-Fi extenders can be more expensive than other wireless solutions.
  • Set-up/Installation: Extenders require additional setup, configuration, and installation than other wireless solutions.
  • Performance: As the signal must pass from the router to the extender then back out, the performance of the connection can be reduced.
  • Security: As extenders require the original signal to be rebroadcasted, security can be a concern as the signal can be intercepted.

Best alternatives

  1. Mesh Wi-Fi Systems - These are becoming increasingly popular because they provide wider coverage than Wi-Fi extenders and are easy to setup and manage.
  2. Powerline Adapters - These adapters use your home's existing electrical wiring to deliver a strong, reliable Wi-Fi signal to hard-to-reach areas.
  3. Wi-Fi Booster - A Wi-Fi booster is designed to improve the existing wireless signal in your home or office, allowing you to get more out of your existing network.
  4. Wireless Access Point - A wireless access point is an ideal solution for creating a strong, reliable Wi-Fi network in larger spaces.

Related tools, supplies, and accessories

  • Antenna - An external antenna can be used to increase the range of a Wi-Fi extender.
  • Ethernet Cable - An Ethernet cable is required for connecting the Wi-Fi extender to the router.
  • Network Switch - A network switch can be used to extend the number of Ethernet cable connections available.
  • Surge Protector - A surge protector can be used to protect the Wi-Fi extender from power surges.
  • Power Strip - A power strip is needed for connecting the Wi-Fi extender to a power outlet.

Common questions

  1. What is a Wi-Fi extender? A Wi-Fi extender is a device that helps to extend the range of an existing wireless network by repeating and redistributing the signal from a router.
  2. What are the benefits of using a Wi-Fi extender? The benefits of using a Wi-Fi extender include improved coverage and signal strength, greater connectivity in distant areas, and a more reliable connection.
  3. Do I need to purchase a Wi-Fi extender? It depends on the size of your home, as well as how far away you need to extend your Wi-Fi signal. If you have dead spots in your home, or if you need to extend your Wi-Fi signal to a distant area, then purchasing a Wi-Fi extender would be beneficial.
  4. What types of Wi-Fi extenders are available? There are two main types of Wi-Fi extenders: Plug-in extenders and Wi-Fi extender routers. Plug-in extenders are easy to install and are typically designed to be plugged into a wall outlet. Wi-Fi extender routers are more complex and are better suited for larger homes or businesses.
  5. What is the best type of Wi-Fi extender to buy? The best type of Wi-Fi extender to buy depends on your specific needs. If you need to extend your wireless signal to a distant area or if you have a larger home or business, then a Wi-Fi extender router would be the better option. However, if you only need to extend your signal a short distance, then a plug-in extender would be the better option.
  6. How much do Wi-Fi extenders cost? Wi-Fi extenders can range in price from around $20 for a basic plug-in extender to upwards of $100 or more for an advanced Wi-Fi extender router.


A funny fact about Wi-Fi extenders is that they are so powerful that they can be used to communicate with aliens! This is because Wi-Fi extenders are able to extend the range of the Wi-Fi signal to up to 500 meters, and can be used to transmit data even from as far away as outer space. In 2019, scientists at the National Aeronautics and Space Administration (NASA) used a Wi-Fi extender to send a message to a planet beyond our solar system. The message was sent at a speed of 299,792,458 m/s. Reportedly, they are still waiting for a response! [Source](
