Routers with faster processors and more RAM can handle more data traffic simultaneously, leading to smoother performance, especially with multiple connected devices. Look for routers marketed as “high-performance” or those that explicitly mention powerful processors.
- Antennas: Routers with external, adjustable antennas generally offer better signal strength and range than those with internal antennas. The number and quality of antennas can impact how well the signal reaches all corners of your home.
- MU-MIMO Technology: Multi-User, Multiple-Input, Multiple-Output (MU-MIMO) is a technology that allows a router to communicate with multiple devices simultaneously, rather than one at a time. This significantly improves efficiency and speed when you have many devices connected.
- Beamforming: This feature directs the WiFi signal directly towards connected devices, rather than broadcasting it equally in all directions. This strengthens the signal and improves performance for individual devices.
- Ports: Ensure the router has enough Ethernet ports for your wired devices and that it supports the latest Ethernet standards (like Gigabit Ethernet) for optimal wired speeds.
Mesh WiFi Systems: Eliminating Dead Zones
If you live in a larger home or have a home with multiple floors or thick walls, a traditional router might struggle to provide a strong signal throughout. This is where mesh WiFi systems shine.
A mesh system consists of a main router unit and several satellite “nodes” or “points” placed strategically around your home. These nodes work together to create a single, seamless WiFi network.
- How They Work: The main router connects to your modem, and the satellite nodes communicate with each other and the main router, extending the WiFi coverage. When you move around your home, your devices automatically connect to the strongest signal from the nearest node, without any interruption.
- Benefits:
- Eliminates Dead Zones: Provides consistent, strong WiFi signal in every room.
- Seamless Roaming: Your devices switch between nodes automatically, so your connection never drops.
- Easy Setup and Management: Most mesh systems come with user-friendly mobile apps for setup, monitoring, and guest network creation.
- Scalability: You can add more nodes to expand coverage further.
- When to Consider a Mesh System: If you’ve tried range extenders with limited success, have a home larger than 2000 square feet, or experience significant signal drops in certain areas, a mesh WiFi system is likely the best solution.
Boosting Your Signal: WiFi Extenders and Powerline Adapters
While a new router or a mesh system are the most impactful upgrades, sometimes you might need to supplement your existing network to reach specific areas or improve signal strength in a particular spot.
WiFi Extenders (Repeaters)
WiFi extenders are relatively simple devices that capture your existing WiFi signal and rebroadcast it, effectively extending the range of your network.
- How They Work: You place an extender midway between your router and the area with weak WiFi. It picks up the signal from the router and sends out its own signal.
- Pros:
- Easy to Set Up: Generally plug-and-play.
- Affordable: Typically less expensive than mesh systems.
- Cons:
- Can Halve Bandwidth: Many extenders create a separate network or have to use the same radio for receiving and transmitting, which can significantly reduce the available bandwidth.

- Limited Effectiveness: Performance can be inconsistent, and they don’t always solve underlying signal strength issues.
- Best Use Cases: Small dead spots or to boost signal to a single device in a nearby room. For larger homes or more robust solutions, consider a mesh system.
Powerline Adapters
Powerline adapters utilize your home’s existing electrical wiring to transmit internet data.
- How They Work: You plug one adapter into a power outlet near your router and connect it to the router via an Ethernet cable. You then plug a second adapter into a power outlet in the room where you need internet access and connect your device to it via Ethernet cable. Some powerline kits also include WiFi-enabled adapters that create a WiFi hotspot in the remote location.
- Pros:
- Bypasses Walls: Effective for getting a wired connection through thick walls that might impede WiFi signals.
- Stable Connection: Can offer a more stable connection than WiFi extenders in some situations.

What is the most impactful single purchase for improving WiFi speed?
The most impactful single purchase for dramatically improving your WiFi speed is typically a new, high-performance WiFi router. Older routers, especially those that are several years old, may not support the latest WiFi standards like WiFi 6 (802.11ax) or WiFi 6E, which offer significantly faster speeds, lower latency, and better performance in crowded environments. Upgrading to a router with these newer standards can unlock the full potential of your internet service and provide a noticeable boost to all connected devices.
Beyond the WiFi standard, consider a router with a powerful processor and ample RAM. These internal components allow the router to handle more devices and more demanding tasks, such as streaming 4K video or online gaming, without performance degradation. Look for routers that advertise features like MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) and beamforming, as these technologies help direct WiFi signals more efficiently to your devices, further enhancing speed and reliability.
Should I upgrade my modem or my router first?
Generally, you should prioritize upgrading your WiFi router first if your primary goal is to increase your WiFi speed and improve the wireless experience within your home. Your modem’s primary function is to convert the internet signal from your Internet Service Provider (ISP) into a format that your home network can use. While a slow modem can be a bottleneck, if your ISP plan’s speed is not being fully utilized by your current router, a new router will yield more immediate and noticeable improvements to your wireless performance.
However, if your modem is very old and does not support the full speed of your internet plan, or if your ISP explicitly recommends a newer modem for optimal performance with their service, then a modem upgrade might be necessary. It’s a good idea to check your modem’s specifications against your internet plan’s advertised speeds. If your modem is significantly older than your router and appears to be limiting your connection speed, then upgrading it could be a worthwhile step before or in conjunction with a router upgrade.
What is a WiFi mesh system, and is it right for me?
A WiFi mesh system consists of a main router and several satellite “nodes” that work together to create a single, unified WiFi network throughout your home. Unlike traditional WiFi extenders that can sometimes create separate network names and halve bandwidth, mesh systems seamlessly hand off your devices from one node to another as you move around, ensuring consistent coverage and speed. This makes them ideal for larger homes or those with many rooms and dead zones where a single router struggles to provide adequate signal strength.
You should consider a WiFi mesh system if you frequently experience weak or unreliable WiFi in certain areas of your home, or if you have a multi-story house. They are also beneficial if you have a large number of connected devices that require consistent and strong WiFi signals. While mesh systems can be more expensive than a single router, the improved coverage and performance they offer can be invaluable for eliminating frustration and ensuring all your devices function optimally.
How do WiFi extenders compare to mesh systems for speed?
WiFi extenders, also known as repeaters, work by capturing your existing WiFi signal and rebroadcasting it. While they can extend the reach of your WiFi, they often do so at the expense of speed. Many extenders halve the available bandwidth because they use the same radio to both receive the signal from the router and transmit it to your devices. This can lead to slower speeds and a less stable connection, especially when multiple devices are connected.
Mesh WiFi systems, on the other hand, are designed for seamless coverage and speed. They use dedicated backhaul (either wired or wireless) between the nodes to communicate with each other and the main router, minimizing performance degradation. This allows for a more consistent and faster experience across your entire home, as devices are intelligently directed to the strongest signal without a significant loss in speed. For users prioritizing speed and consistent performance across a large area, mesh systems are generally superior to traditional extenders.
What is WiFi 6, and should I buy a WiFi 6 or WiFi 6E router?
WiFi 6, also known as 802.11ax, is the latest mainstream WiFi standard. It brings significant improvements over its predecessor, WiFi 5 (802.11ac), including faster speeds, increased capacity for more devices, better efficiency in crowded networks, and improved battery life for connected devices. WiFi 6 achieves these advancements through technologies like Orthogonal Frequency-Division Multiple Access (OFDMA), 1024-QAM modulation, and improved MU-MIMO.
WiFi 6E builds upon WiFi 6 by adding support for the 6 GHz frequency band. This new band offers more channels and less interference compared to the crowded 2.4 GHz and 5 GHz bands. Therefore, if you have WiFi 6E-compatible devices and your ISP plan is fast enough to benefit from these new speeds, purchasing a WiFi 6E router can provide the absolute fastest and most reliable WiFi experience currently available. However, if your devices are not WiFi 6E compatible or your internet speed is not exceptionally high, a good WiFi 6 router will still offer a substantial upgrade.
What role do Ethernet cables play in boosting WiFi speed?
While this article focuses on wireless improvements, Ethernet cables play a crucial role in achieving the fastest possible speeds, especially for stationary devices. Connecting high-demand devices like desktop computers, smart TVs, gaming consoles, or streaming boxes directly to your router via an Ethernet cable bypasses the limitations of wireless transmission. This offers a more stable and often significantly faster connection than WiFi, as it eliminates potential interference and signal degradation.
To maximize the benefits of your upgraded router and internet service, it’s essential to ensure you are using appropriate Ethernet cables. For speeds exceeding 1 gigabit per second (Gbps), you’ll need Cat 6 or Cat 6a Ethernet cables. Using older Cat 5 or Cat 5e cables can bottleneck your connection, preventing you from realizing the full potential of your network. Therefore, incorporating quality Ethernet cabling into your setup is a vital, albeit wired, component of a truly fast and reliable home network.
Are “gaming routers” actually faster than regular routers?
“Gaming routers” often incorporate features specifically designed to prioritize network traffic for gaming and reduce latency, which can lead to a perceived improvement in gaming performance. These features might include Quality of Service (QoS) settings that allow you to dedicate bandwidth to gaming applications, built-in VPNs for secure connections, or more powerful hardware for handling multiple connections simultaneously. Some gaming routers also offer advanced steering technologies to ensure devices connect to the optimal band.
However, the term “gaming router” can sometimes be more of a marketing designation than a functional difference for everyday use. A high-performance router, regardless of its marketing label, that supports the latest WiFi standards, has a robust processor, and offers advanced QoS settings, can provide similar or even superior performance for gaming and other demanding tasks. The key is to look for routers with strong specifications and features that directly address your needs for speed, low latency, and network management, rather than solely relying on a “gaming” label.
