Do I need a Wi-Fi booster?

Wi-Fi boosters, also known as Wi-Fi range extenders or repeaters, are devices that help improve your existing Wi-Fi coverage in areas with poor or no signals from your wireless router. They work by receiving the wireless signal from your router and rebroadcasting it to create a stronger signal in weak coverage areas.

Do I need a Wi-Fi booster?

A Wi-Fi booster can benefit your home network if your router does not provide enough Wi-Fi range for all your needs. However, before deciding to get a booster, it helps first to understand the factors causing Wi-Fi dead zones in your home and ways to optimize your current setup.

Common causes of Wi-Fi dead zones at home

Several factors can contribute to Wi-Fi dead zones in a home:

  • Obstructions – Thick walls, ceilings, large furnishings like cabinets can physically block or weaken wireless signals. Wi-Fi uses radio frequency waves similar to how radio broadcasts travel through air. Any barriers impeding the path of these waves can decrease signal strength.
  • Distance from router – Wi-Fi signals get weaker the farther users move from the wireless router. 2.4GHz signals can cover about 100 to 150 feet indoors, but 5GHz signals only reach about 35 to 90 feet on average.
  • Interference – Signals from baby monitors, microwaves, cordless phones occupying the same wireless frequencies compete and interfere with Wi-Fi signals. This leads to slower network speeds and connectivity issues.
  • Old router hardware – Outdated Wi-Fi routers tend to have less transmitting power compared to newer models. If your router is 5 or more years old, its weakening signals can impact wireless coverage.
  • High network usage – During peak usage hours with multiple users streaming, gaming, video conferencing over Wi-Fi simultaneously, even robust routers can slow down, leading to choppy speeds and dead zones.

Tips to improve existing Wi-Fi coverage

Before getting a Wi-Fi booster, simple adjustments around your home can potentially fix dead zone issues for better whole-home coverage:

  • Adjust router placement – Place the wireless router in a central area free from obstructions. Removing objects blocking antennae also helps optimize Wi-Fi signals.
  • Update router firmware – Check for and install the latest firmware update for your router. Updates often upgrade Wi-Fi performance.
  • Enable QoS – Quality of Service gives high-bandwidth activities like gaming and streaming higher priority and more speed. This maintains fast speeds network-wide.
  • Adjust Wi-Fi bands – Switch 5GHz-only devices to 5GHz for faster speeds. Reserve 2.4GHz for longer range throughout your home.
  • Reduce Wi-Fi interference – Simple fixes like not using the microwave while Wi-Fi is in use can reduce interference issues. Checking settings for least congested wireless channels also helps.
  • Upgrade your router – New mesh router systems with Wi-Fi 6 offer faster wireless speeds, expanded coverage, and improved capacity to minimize dead zones.

If Wi-Fi still remains spotty after troubleshooting, then Wi-Fi extenders are the next step.

Should I buy a Wi-Fi booster?

Purchasing a dedicated Wi-Fi booster like a wireless repeater or Wi-Fi extender makes sense if you have localized dead zones in some parts of your home. These compact plug-in devices cost between $50 and $200 depending on booster range and number of Ethernet ports.

Key benefits of Wi-Fi signal boosters:

  • Dedicated wireless access point – Dual or tri-band Wi-Fi boosters offer an extra wireless access point for faster data rates for nearby devices. Helps avoid network congestion and buffering issues.
  • Stronger signal strength ??? Wi-Fi boosters capture, amplify and rebroadcast Wi-Fi signals from the router into areas that are outside of its range. Expanding wireless coverage to get rid of dead zones.
  • Ease of installation ??? Most Wi-Fi boosters just need an electrical outlet and a few minutes to set up. No additional wiring needed in most homes. Easy to test placement too before permanently mounting.

However, there are also some downsides to be aware of before investing in an extender:

  • Half speed bandwidth ??? Maximum data rates when connected to a Wi-Fi booster are typically half that of what your main router offers since data has to be received and re-transmitted.
  • No impact on router performance ??? Adding an extender will not improve any underlying issues due to router hardware limitations or network congestion during peak hours.
  • Potential interference ??? Poorly placed boosters can negatively impact router signals. Careful testing of location is vital for optimal benefit.

Wi-Fi extenders buying guide

When shopping for a Wi-Fi signal booster for home use, consider these key factors:

  • Compatibility – The booster should work with any Wi-Fi router brand but verify protocol and band support matches your wireless network.
  • Coverage – Estimate the size of your dead zone and buy an extender that can adequately cover the required area. Long-range boosters over 1,000 sq ft work best for larger homes.
  • Speed – Match the peak data rates your current router provides. AC1200 or AC1750 boosters are common for mainstream use. Wi-Fi 6E models offer future-proofing.
  • Number of bands ??? Dual or tri-band Wi-Fi boosters allow both 2.4GHz and 5GHz signal support for all-round use with varying client devices. Have dedicated data channels to reduce congestion issues when connected.
  • Number of Ethernet ports – Having one wired LAN port allows connecting a wired device like a smart TV or games console to the extender instead of using Wi-Fi.

Leading Wi-Fi extender brands like Netgear, TP-Link, Linksys, and ASUS offer reliable performance based on Wirecutter???s recent testing. Consider buying from retailers that accept opened returns in case the booster fails to resolve Wi-Fi issues.

Key takeaways on Wi-Fi boosters

  • Try simple adjustments first before installing extenders for improved Wi-Fi range. From finding the optimal spot for your router to upgrading firmware and hardware.
  • Adding a Wi-Fi booster is easy and affordable. It expands wireless coverage delivering faster speeds in problem zones.
  • Check that the booster specifications match and works with your home network before buying one. Consider long-range models for larger homes.

Conclusion

In summary, while Wi-Fi boosters have benefits, improving wireless coverage for reduced dead zones, they are more of a workaround “band-aid” rather than resolving underlying network issues due to interference, congestion or simply router hardware limitations because of age or range.

Invest first in analyzing current router placement and settings, reducing interference from other devices, upgrading firmware and enabling QoS settings before deciding on whether buying a Wi-Fi extender or upgraded mesh networking router system makes the most long-term sense for better whole home connectivity.

Frequently Asked Questions

  1. Who needs a WiFi booster?
    Those with an existing WiFi router that leaves some parts of their home with a weak wireless signal or dead zones can benefit from a WiFi booster. It helps amplify signals into these unreachable areas.

  2. Do WiFi boosters really work?
    Yes, WiFi boosters are proven to effectively improve signal range and strength by receiving wireless signals and rebroadcasting them. This fills in coverage gaps that exist beyond your router’s wireless range.

  3. Do I need a new router or WiFi extender?
    Try adjusting your current router’s settings and placement first before deciding on either option. If issues persist only in some rooms, a cheaper WiFi extender makes sense. But if the router itself is old or troubles are network-wide, investing in a new upgraded router is the better fix.

  4. Where should I place my WiFi extender?
    Ideally midway between your wireless router and the WiFi dead zone. Avoid placing it too close to the router or too far into weak coverage areas for optimal signal relay. Test performance after setup to adjust positioning as needed.

  5. How do I know if I need a 5GHz WiFi extender?
    Check what WiFi bands your router broadcasts on. If it supports dual-band 2.4GHz and 5GHz already, match capabilities when choosing an extender so you maintain support for devices that connect on either frequency.

  6. Does a WiFi booster reduce speed?
    Connecting to an extender typically offers half the maximum wireless data rate or speed that your router provides since it’s receiving then retransmitting. This is why they are not recommended for bandwidth-intensive uses like gaming or 4K streaming.

  7. Can I use WiFi boosters to extend my WiFi to the backyard/garage?
    Long-range WiFi boosters that specify outdoor signal coverage will be able to effectively transmit into your yard or garage but likely at much slower speeds suitable only for basic web browsing use.

  8. What is better WiFi repeater vs extender?
    WiFi repeaters and WiFi extenders refer to the same type of product designed to improve wireless coverage areas by receiving and re-broadcasting WiFi signals from an existing router. Think of the terms as interchangeable.

  9. How far can WiFi boosters extend?
    Depends on the booster but roughly add between 25 to 70% more range onto what your current router covers. Models explicitly labeled long-range boosters that specify expanded coverage typically reach up to 1000+ square feet or cover a home up to 5000 sq ft total.

  10. Can you have too many WiFi boosters?
    Adding more than 1 or 2 WiFi boosters can negatively impact performance instead. The multiple devices attempting to extend signals from the same router creates wireless interference. Most homes only require a single booster.

  11. Where is the best place to position WiFi booster?
    For optimal signal relay, install the WiFi extender halfway between the router’s location and the dead zone location while keeping it out in the open, away from obstructions. Use the booster’s signal indicators when testing locations.

  12. Do outlets affect WiFi boosters?
    Yes, connect plug-in WiFi boosters directly to wall outlets instead of power strips. Electrical interference from other devices on the same strip can disrupt signals. Also, keep boosters separated from appliances and electronics to minimize interference issues.

  13. How can I boost my WiFi speed without an extender?
    Simple adjustments like finding an obstruction-free central spot for your router, updating router firmware, using a compatible LAN ethernet cable for wired devices instead of WiFi, disabling WiFi on devices using ethernet, or upgrading your router can all help increase speeds without needing an extender.

  14. Will two WiFi boosters work?
    You can setup two boosters in very large homes placing them on opposite sides to cover distant zones with weak signals. But generally more than one risks degraded performance due to wireless interference between them when both trying to connect to the same router.

  15. Can using old hardware like routers affect WiFi range and cause dead zones?
    Yes, aging router hardware often lacks the transmission power and wireless capabilities of newer models. They can struggle providing consistent, reliable signals leading to dead zones even with routine use. Replacing outdated routers helps significantly.
