How WiFi Boosters Work

WiFi boosters, also called range extenders, help increase WiFi signals in areas your router doesn’t reach well. They connect wirelessly to your router then rebroadcast the signal at full strength.

Boosters have limited bandwidth so internet speeds generally decrease the farther users are from the router. Using Ethernet backhaul from the booster to router maintains full speeds.

Benefits of Adding a Second Extender

There are several potential perks of networking two WiFi boosters:

  • Extend coverage farther – Daisy chaining boosters reaches distant spots by leapfrogging the signal. This expands WiFi access to the edge of properties.
  • Less interference – Strategically placing boosters creates clearer signal pathways free of obstructions.
  • More bandwidth – Some boosters have Ethernet ports to connect devices via cable. This provides higher speeds for stationary equipment without taxing the WiFi network.
  • Prioritize bands – Utilize the 2.4GHz band for longer range to outer buildings and 5GHz for high-performance needs closer to the source.
  • Seamless roaming – Handing off connections from one booster to the next prevents dropped signals as users move around.

Drawbacks of Dual Extender Setups

Using two WiFi extenders can also introduce some potential downsides:

  • Halved bandwidth – Each extender typically has half the available bandwidth of the router itself, so adding more partitions speed capacity.
  • Double NAT issues – Network address translation (NAT) helps boosters connect properly but also risks limiting speeds or breaking connectivity.
  • Signal noise – Nearby boosters broadcasting on the same WiFi channel can create interference and reduced performance if not carefully coordinated.
  • Complexity – Daisy chaining multiple boosters makes WiFi analysis and troubleshooting more difficult with multiple points of possible failure to check.

Best Practices for Multiple Boosters

There are several key tips to follow when linking two WiFi boosters:

Carefully Position Boosters

  • Place boosters in between dead zones to bridge gaps in coverage.
  • Elevate boosters for clearer signal paths without obstructions.
  • Ensure sufficient overlap of extended networks for smooth device roaming as users move about.

Assign Different Channels

  • Check channels used by your router and other nearby WiFi networks.
  • Set each extender to broadcast on the least congested channel to avoid interference.

Enable Ethernet Backhaul

  • Connect one or both boosters to the router via Ethernet cable.
  • This maintains fast, reliable speeds since data doesn’t retransmit wirelessly between boosters.

Enable Same SSID Network

  • Give both extenders and router the same network name (SSID) and password.
  • This allows devices to roam seamlessly without needing to reconnect as they switch connections.

Update Firmware

  • Check periodically for latest firmware versions for router and both extenders.
  • Updates often resolve bugs and improve performance of WiFi networks.

Alternative Ways to Boost Weak WiFi Signals

Beyond plugging in a second WiFi booster, there are a few other options to try strengthening wireless internet access:

  • Upgrade router – Newer routers with WiFi 6/6E support faster speeds, expanded capacity, and reliable signals. A mesh router system can also help blanket homes with strong WiFi.
  • MoCa adapters – Use coaxial cables already installed in homes to backhaul network signals, maintaining wired speeds over WiFi.
  • Powerline adapters – leverage existing electrical lines as a backbone for networking. Models with WiFi build in power access points.
  • Run Ethernet cable – Directly connecting devices via cable guarantees fast, reliable connectivity though it limits mobility.

Key Takeaways

  • Adding a second WiFi extender can further boost range and capacity but also risks slowing speeds if not properly configured.
  • For best results, carefully position boosters to bridge gaps, assign different channels to prevent interference, and enable Ethernet backhaul.
  • Alternative options like upgraded routers, MoCa/powerline adapters, or running new Ethernet cable can also help stabilize weak WiFi signals.
  • Dual booster networks take more effort to set up but provide better whole-home coverage and reliability when optimized properly.


Pairing two WiFi boosters can provide expanded WiFi access throughout larger homes and properties. Paying attention to optimal placement, reducing interference, and maintaining wired backhaul connections will ensure dual extenders enhance rather than hinder network performance. Taking the time to properly configure and manage dual booster setups allows even distant devices to connect with fast, reliable wireless internet.

Frequently Asked Questions

  1. What are the disadvantages of using two WiFi boosters?
    Potential drawbacks of dual boosters include halved bandwidth, double NAT issues, signal interference if broadcasting on same channels, and added network complexity.
  2. Where should I position multiple WiFi extenders?
    Carefully place boosters in between dead zones to bridge gaps in coverage, elevated for clearer signals without obstructions, and with enough overlap for smooth device roaming.
  3. Is it better to get a WiFi booster or mesh network?
    Mesh systems are easier to set up but more expensive. Boosters provide targeted improvements in weak signal areas for less cost but require more effort to optimize.
  4. Can I use WiFi boosters from different brands?
    You can mix and match boosters from different manufacturers but may lose out on optimized performance and seamless roaming between brands.
  5. Should I get a dual band or tri band WiFi extender?
    Tri band boosters feature a dedicated band for booster to router transmissions, reducing congestion. But dual band models are typically cheaper with simpler setup.
  6. Do I need new WiFi boosters for WiFi 6?
    You don’t need latest WiFi 6 boosters to improve range and speeds. But they do provide faster peak wireless data rates if you have WiFi 6 compatible devices.
  7. Why does my WiFi booster keep disconnecting?
    Frequent booster disconnects are often due to poor placement, interference from nearby devices, incompatible firmware, or overloaded network capacity.
  8. How can I optimize placement of dual WiFi extenders?
    Make sure to position them in dead zone gaps allowing enough overlap for roaming, elevated for line of sight, and use Ethernet backhaul to relieve wireless congestion.
  9. What causes WiFi signals to degrade?
    Distance from router, interference from devices or structures, network congestion, outdated equipment, and environmental factors all contribute to WiFi signal degradation.
  10. Should I disable my router’s WiFi when installing a booster?
    You don’t need to disable the router’s WiFi but setting it to low transmit power can reduce overlap and confusion connecting devices.
  11. Do powerline network extenders work as good as WiFi boosters?
    In homes with newer electrical wiring, powerline signal range and speeds often outperform WiFi extender capabilities.
  12. Can using too many WiFi extenders reduce network speeds?
    Adding more than 2 or 3 daisy-chained boosters almost always introduces bandwidth limitations, lag, and other performance issues.
  13. Where should I place my second WiFi extender?
    The second booster should be positioned to bridge gaps in coverage that remain after installing the first extender while allowing some overlapping coverage.
  14. Can I use the same SSID name for both my router and WiFi extenders?
    Yes, using the same SSID and password for boosters and router provides seamless roaming as devices switch connections moving around.
  15. How far should Wi-Fi boosters be from the router?
    Boosters should be close enough to reliably connect to router at good speeds but far enough to effectively blanket weak coverage areas, usually 30-100 ft apart.
  16. What factors affect Wi-Fi booster performance?
    Distance, interference, network demand, environmental factors, firmware, and device capabilities can all impact Wi-Fi extender speeds and reliability.
  17. Will a more expensive Wi-Fi booster work better?
    More expensive boosters often pack helpful features like tri-band, but well-positioned dual-band models can provide reliable extended coverage at lower costs.
  18. How do I know if I need one or two Wi-Fi boosters?
    If a single centrally located booster leaves some rooms/areas still with weak signals, adding a second extender specifically targeting those remaining dead zones is worth trying.
  19. Do I need a booster that supports same speeds as my router?
    Your booster’s max speeds just need to match or exceed the typical bandwidth needs of connected devices rather than always matching the router.
