What causes poor WiFi signal?

There are a few key factors that can contribute to poor WiFi coverage in your space:

Distance from the router

WiFi signals weaken significantly the further you move away from your wireless router. While today’s routers have an average range of 150 to 300 square feet, the signal has to pass through walls and other obstructions that further limit range. If your router cannot reach all areas with a strong signal, dead zones with no connectivity can occur.


WiFi signals operate on unlicensed radio frequencies that are also shared by other household devices like baby monitors, Bluetooth gadgets, microwaves, and cordless phones. If too many devices emit radio signals in the same frequences, interference occurs, slowing WiFi speeds.


Dense materials in your home weaken radio signals as they pass through. Brick and concrete walls, metal appliances, mirrors, fish tanks and more can all block, reflect or absorb signals to limit range. Additionally, utility pipes and ductwork create barriers for the signals.

Old/inefficient router

If your router is over 3-4 years old, replacing it with a newer model can boost speeds and widen coverage area. New mainstream routers include better internal antennas, amplifiers, and newer technologies to transmit faster, stronger signals through obstacles.

When do I need a WiFi booster?

Adding WiFi extenders and access points can amplify signals for better whole-home coverage. Boost your network if you experience any of the following WiFi connectivity problems:

Dead zones

If you notice certain spots in your home with extremely low signal strength, frequent disconnects or no service at all, WiFi boosters can fill coverage gaps. Target boosting devices to areas farthest from your router first.

Slow internet speeds

While an internet plan upgrade can raise your maximum speeds, strength of local WiFi networks plays a big role too. Boosting signals in weak areas will help devices maintain consistently high speeds closer to your plan’s limits.


Latency sensitive applications like streaming video, gaming, video calls and even web browsing can stall and buffer due to poor signals. Extending your network keeps latency low for smooth streaming and real-time apps.

Router overload

If your existing router cannot handle the sheer number of connected devices at once, adding WiFi access points or routers handling client connections can prevent overloads for better performance across all gadgets.

How to choose a WiFi booster

With different designs, standards and features available, use the following guidelines when shopping for signal boosters:

WiFi range extender

This is the most affordable and compact option that plugs directly to an outlet midway between your router and weak area. While easy to set up, their small antenna and single network name can limit speeds.

Mesh WiFi system

Full home mesh systems include a base router unit with satellite modules placed around your space to create a unified network. Mesh routers feature robust radios, intelligent steering between access points and simple setup. But fully robust mesh systems have a high upfront cost.

Wireless access point

Access points connect to your router via ethernet cable (you’ll need wiring in place), but feature the best bandwidth and range available. They allow for multiple backhaul channels and guest networking, but require more IT experience to configure.

Considerations when choosing either option:

WiFi standards – Look for support of the latest WiFi 6E or WiFi 6 standards that operate on less crowded frequencies for faster speeds and less interference.

Backhaul – Mesh and access point systems need a dedicated wireless or wired backhaul link to carry signal between router and boosters without choking client device connections.

Band steering – Boosters that can intelligently connect your devices to less congested bands (2.4Ghz vs 5Ghz) maintain speed performance.

Antenna design – Units with 4 to 8 internal or external high gain antennas in a multi-direction layout best cover range throughout large homes.

Key takeaways on WiFi boosters

  • WiFi range can be limited by distance, interference and obstructions – causing dead zones with poor connectivity in parts of your home.
  • Boosters fill in weak spots by amplifying signals for consistent coverage and speed, resolving connectivity problems.
  • Options like range extenders, mesh systems and access points all serve to boost networks, but vary in layout, features and pricing.
  • Consider ease of use, WiFi standards, band steering and antenna design when choosing a suitable signal booster.


Adding WiFi boosters can effectively and affordably resolve frustrating dead zones and intermittent connections from an aging router. Newer solutions like mesh networks amplify signals for reliable whole-home coverage but often carry higher price tags. For large homes with many obstructing materials, professional installers can survey spaces to strategically place access points wired to your router via ethernet backhaul for best commercial-grade networks. Consider the WiFi problems you want to fix and evaluate different booster system features before choosing the best option matching needs and budget. Reliable in-home connectivity greatly impacts how we work, learn and entertain ourselves each day.

Frequently Asked Questions

  1. How do I know if I need a WiFi booster?
    If you experience frequent disconnections, slow internet speeds, or inability to connect in certain areas – it likely indicates poor WiFi coverage that a booster can improve. Run internet speed tests in multiple spots at both 5Ghz and 2.4Ghz bands to quantify issues.
  2. Where should I place my WiFi booster?
    Ideally midpoint between your main router and the weak coverage area – allowing the booster to receive then re-transmit signal further. Outlets in hallways can often achieve this efficiently.
  3. Do powerline WiFi extenders work well?
    Powerline adapters use electrical wiring to carry signal making them easy to install, but slower speeds than wireless mesh and direct ethernet access points when extending networks.
  4. Should I get a WiFi extender or mesh network?
    WiFi extenders are more affordable for 1-2 dead zone fixes, but offer slower speeds. Mesh kits cost more, include dedicated backhauls for faster speeds and support growing number of devices better – but require more units for whole home coverage.
  5. Can I use an old router as WiFi extender?
    Yes, many routers have modes to function as just access points. Connect via ethernet cable to your main router, disable DHCP service, set a different SSID and match security settings to extend existing WiFi smoothly.
  6. Do WiFi boosters reduce speed?
    Boosters extended your WiFi coverage without reducing speeds – if set up optimally. Adding capacity via network extensions prevents router overload and maintains speed performance. Mesh systems even increase speeds in dead zones.
  7. How many WiFi boosters do I need?
    Most homes need just 1-3 boosters: one placed strategically in problem areas, or mesh satellites spaced across larger spaces. Limit to 3-5 boosters maximum before considering upgrading internet plans for more bandwidth.
  8. Where should I place WiFi extender?
    Ideally in the center between your main router and the weak WiFi area – often a hallway outlet or floor midway. The extender then receives signal cleanly before amplifying WiFi further.
  9. Do I need special wiring for mesh WiFi?
    One benefit of mesh is leveraging WiFi itself to connect router and satellites. But models with ethernet ports allow satellite wiring to router for fastest backhaul traffic flow without choking main network.
  10. Can I use old router as wireless repeater?
    Yes, many routers have wireless repeater modes with the same SSID. Connect via ethernet cable to your main router, disable DHCP on old one, and ensure security protocols match between the two.
  11. Do I need Managed WiFi?
    For robust connectivity across corporate environments, warehouses and campuses – managed WiFi uses centralized controllers to coordinate access points while gathering analytics. Helpful for scaling density and applying traffic shaping quality controls.
  12. What is daisy chain mesh WiFi?
    Daisy chaining means connecting mesh satellite units in a series – one node connects wirelessly to main router while next node connects to first one. Risk of high latency makes Ethernet backhaul better for performance.
  13. Can I convert old router to wireless access point?
    Absolutely. Connect via Ethernet to main router, change old router’s LAN IP address to prevent conflicts, disable DHCP so it assigns no addresses, then set same SSID/password to extend existing network seamlessly.
  14. Where to place WiFi extender for best signal?
    In the middle between your main router and weak signal area – look for a central hallway outlet to plug extender into, allowing it to receive signal strongly from router before amplifying WiFi further.
  15. Do Mesh WiFi systems work with cable Internet?
    Yes. While mesh kits include a main router that connects directly to your cable modem, satellite modules only expand WiFi coverage. So mesh systems can boost wireless signals from any internet source.
  16. Can I use a WiFi booster with Hughesnet?
    Yes – popular options like WiFi extenders and mesh networks will successfully amplify Hughesnet satellite internet signals for better coverage. Just take care not to daisy chain too many boosters to risk high latency.
  17. Where should I place WiFi repeater?
    For best performance, install halfway between your main wireless router and the area with poor signal strength. Hallway electrical outlets are ideal central locations to catch signal strongly before repeating WiFi outwards further.
  18. Do WiFi Boosters reduce Internet speed?
    When positioned well, WiFi boosters maintain – not reduce – your internet speeds in expanded signal areas. They add more wireless capacity preventing router overload. Mesh systems with dedicated backhaul even increase WiFi speeds compared to weak router-only coverage.
