What Is Mesh WiFi? (& How Does It Work?)

Compared to other forms of WiFi network setups, mesh WiFi networks provide distinct advantages. Let’s look at some of the more common setups compared to mesh WiFi.

• • Mesh WiFi vs. traditional WiFi – Mesh WiFi offers better coverage by using multiple nodes to eliminate dead zones, whereas traditional routers often struggle to cover large or complex spaces effectively.
  • Mesh WiFi vs. wired ethernet networks – Mesh WiFi offers wireless connectivity and scalability without the need for cables, in contrast to ethernet which is highly stable but less flexible to install.
  • Mesh WiFi vs WiFi extenders – Mesh networks use a single network SSID and manage data paths more efficiently than WiFi extenders which often create multiple networks and reduce bandwidth during retransmission.

As most homes typically use traditional WiFi setups, let’s dive into the benefits of mesh WiFi over traditional WiFi.

While mesh WiFi and traditional WiFi systems both serve the purpose of providing wireless internet access, they differ significantly in design, coverage, performance and management. Let’s compare the two below.

• • Traditional WiFi: Typically involves a single router that’s connected to a modem and is responsible for broadcasting WiFi throughout the entire area.
  • Mesh WiFi: Consists of multiple router-like devices. One node connects to the modem and acts as the primary router, while strategically placed nodes help create a grid.

• • Traditional WiFi: Coverage is limited by the range of the single router. Physical obstructions like walls and floors weaken the signal as distance from the router increases.
  • Mesh WiFi: Coverage is extensive, as nodes can be added to eliminate dead zones and ensure consistent signal strength across larger and multi-story buildings.

• • Traditional WiFi: Performance degrades with distance from the router. Users farther away from the router or behind obstructions experience weaker signals and lower speeds.
  • Mesh WiFi: Designed to maintain stronger and more consistent performance throughout the covered area. Nodes communicate with each other to ensure devices are always connected to the strongest signal available.

• • Traditional WiFi: Usually managed through a web-based interface that can be less intuitive. Adding extenders for increased coverage can complicate management and often requires separate network SSIDs.
  • Mesh WiFi: Generally managed through a user-friendly app that offers features like device prioritization, parental controls, and easy guest network setup.

• • Traditional WiFi: Generally less expensive initially as it usually requires just one router.
  • Mesh WiFi: More expensive due to the technology and multiple devices involved, but offers better value for larger spaces or buildings with many obstructions.

• • Traditional WiFi: Scaling up involves adding range extenders or additional routers, which can create a fragmented network with multiple SSIDs.
  • Mesh WiFi: Easily scalable by simply adding more nodes. The system remains unified with a single SSID.

• • Traditional WiFi: Adequate for small apartments or homes where a single router can provide sufficient coverage.
  • Mesh WiFi: Ideal for larger homes, multi-story buildings and spaces with many physical obstructions where maintaining consistent coverage and performance with traditional WiFi would be challenging.

There are many variables to consider when choosing the best mesh WiFi system for your home or apartment. Make sure to factor in the size and layout of your home, your internet usage or internet habits and the specifications of the mesh WiFi system you’re considering.

Without a mesh network, your WiFi may have issues reaching the other side of the house or reaching the top of the home. Using mesh networks, your coverage area is no longer limited to the size or layout of your home.

However, you may need to design your mesh network with your home in mind. When doing so, make sure to note any dead zones or areas where you’ll want WiFi.

As you determine how to optimize your mesh network, you’ll need to consider all users within your home and what their internet habits are.

• • Streaming: Consider how many people in your household stream video content simultaneously and the quality of the content they prefer.
  • Gaming: If multiple household members play online games, especially competitive multiplayer games, prioritize a stable connection with low latency.
  • Smart devices and users: Smart home devices such as smart speakers, security cameras, thermostats and others typically don’t require a lot of bandwidth. Many connected devices individually may not consume bandwidth, however, dozens of them act like internet vampires.
  • Usage patterns: Consider the peak usage times in your household. For example, evening hours might see the highest usage if all family members are home and using the internet. Bandwidth needs to be sufficient to handle peak load without slowing down.
  • Download and upload speeds: Most activities are heavy on downloads, but if anyone in your household uploads large files, does live streaming, or uses cloud services extensively, consider an internet plan with higher upload speeds.

Mesh network systems can enhance coverage and performance across larger homes or homes with layout challenges.

In a few simple steps you can be up and running with the mesh WiFi system of your choice. While there are many different mesh WiFi systems, like eero, we’ll run through some basic steps for setting up mesh networks so you know what to expect.

1. Choose your mesh WiFi system
   Purchase a mesh WiFi system that meets your coverage needs, budget and the number of devices you plan on connecting. Make sure it has the features you require, like parental controls, home network security and compatibility with your smart home devices – if any.
2. Place your nodes
   Position the main router node in a central location near your modem. Place additional nodes around your home for optimal coverage – in open spaces, and away from obstructions like closets and cabinets.
3. Connect main node to your modem
   Use an Ethernet cable to connect the main node (the one acting as the router) to your modem. This node will act as the gateway to the internet for your entire network.
4. Power up your network
   Plug in the main node to a power outlet and turn it on. Repeat this process for all other nodes.
5. Download the app and create an account
   You can manage most mesh systems from a mobile app. Download the app, create an account and follow the setup instructions.
6. Sync the nodes
   Connect the nodes to your network through the mobile app. You may need to scan QR codes or manually add them.
7. Configure your network
   Set up your WiFi network name (SSID) and password. You can also configure other settings such as guest network options, parental controls, and device prioritization.
8. Test the network coverage
   Walk around your home with a device connected to the WiFi to ensure you have strong signal coverage. Use the app to check each node’s connection strength. Adjust the nodes if there are areas with weak coverage.
9. Regularly update the firmware
   Make sure your mesh system’s firmware is updated to the latest version. New updates can improve performance and security, improving your whole home WiFi overall.

Knowing the possible steps involved in managing a mesh network can help you understand how it can benefit your home.
