How to Check and Improve Your Wi-Fi Speed: Easy Tips for Faster Internet

Low Wi-Fi speed is one of the most common issues in home networks, showing up as slow website loading, video buffering, dropped calls, and unstable app performance. The reasons can range from your provider’s plan to router settings, network congestion, or even the layout of your home. In this guide, we’ll break down what affects Wi-Fi speed, how to properly test your connection, and which steps can help you improve the stability and speed of your wireless network.

Before trying to improve your Wi-Fi, it’s important to accurately measure your current speed. Without this, it’s easy to jump to the wrong conclusions and start changing settings or hardware unnecessarily. Proper testing helps you pinpoint where the bottleneck is: with your provider, the router, the wireless network, or a specific device.

Start by checking the speed over a wired connection using the same device you’ll use for Wi-Fi tests. Connect your computer or laptop directly to the router with an Ethernet cable, then run a speed test using a dedicated service. Examples include:

This test shows the speed from your provider without the influence of the wireless network. If the wired speed matches your plan, your provider’s line and equipment are working properly, and any speed drops are due to Wi-Fi. If the wired speed is low to begin with, tweaking Wi-Fi settings won’t help.

Once you’ve checked the wired speed, switch to Wi-Fi and repeat the speed tests.

For a more accurate picture, it’s best to run several tests at different times and, if possible, on different devices. The same spot can give different results in the morning and evening due to network load or neighbors’ Wi-Fi activity. Plus, different devices have different adapters and may interact with the same router in different ways.

When analyzing the results, don’t just look at download speed. Upload speed, ping, and connection stability matter just as much. High ping or sudden spikes often cause lag in games, video freezes, and video call issues—even if the speed looks good on paper. Only by considering all these factors together can you get a real sense of your Wi-Fi’s condition and start looking for solutions.

The first thing to check is your provider’s plan and the quality of their line. Your router and Wi-Fi can’t deliver more speed than what comes in through the cable. If the line is unstable, there’s packet loss, or the actual speed is lower than promised, your wireless network will only pass that problem along. When in doubt, always rely on your wired speed test results.

The main issues often come from the router itself. Its capabilities directly limit the maximum speed and stability of your Wi-Fi. Older models that only support Wi-Fi 4 aren’t designed for modern internet plans or a large number of devices. Newer standards like Wi-Fi 5 and Wi-Fi 6 handle heavy loads better, process data faster, and are more effective in apartment buildings. Other important factors include the power of the radio module, the number of antennas, and the speed of the network ports.

The frequency band you use and the channel you select are also key.

Channel selection matters too, since multiple networks on the same channel can interfere with each other, reducing speeds and increasing latency.

Nearby Wi-Fi networks, Bluetooth devices, microwave ovens, wireless cameras, and smart gadgets all create radio noise that degrades signal quality. This is especially noticeable in densely populated buildings where dozens of networks operate on the same frequencies.

Thick walls, concrete floors, mirrors, metal structures, and heavy furniture weaken the signal. Even the router’s location matters: a device placed in a corner or hidden in a closet will provide much worse coverage than one positioned closer to the center of your home and higher off the floor.

Network congestion. The more devices using the internet at the same time, the more the available bandwidth is divided up. Downloads, high-quality video streaming, online games, and torrents can significantly slow down other devices—especially if your router isn’t very powerful.

Older smartphones and laptops often have weak Wi-Fi adapters and don’t support modern standards or wide channels. Outdated drivers, active VPNs, antivirus software, and background updates can also lower speed and increase latency. As a result, even with a strong signal, you might get much slower speeds than expected.

Move your router. A router placed in the corner of your apartment, on the floor, behind the TV, or inside a cabinet is already at a disadvantage. The signal spreads unevenly, and a lot of its strength simply gets lost in walls or floors. Moving the router higher off the ground, closer to the center of your home, and away from large appliances and metal objects often gives a noticeable boost to speed and stability—especially in rooms farther from the router.

Switch the frequency band. If your devices support 5 GHz, it’s usually best to use it. In most apartments, this band is less crowded than 2.4 GHz and can deliver higher speeds. Its range is shorter, but within one or two rooms, the difference in connection quality is usually obvious right away. If your device can only connect to 2.4 GHz, be prepared for more modest speed results.

Restart your router. Over time, the device can get bogged down with active connections, glitches, or temporary errors. A simple reboot often restores normal speed and reduces the number of dropouts. It’s also a good idea to check for firmware updates—manufacturers often fix bugs and improve Wi-Fi performance through updates.

Disconnect unused devices. If files are downloading, torrents are running, videos are streaming, or system updates are happening, the speed for all other devices will inevitably drop. Temporarily pausing unnecessary downloads or limiting their speed can noticeably improve the situation without any extra configuration.

Check your cables. Bends, damaged connectors, or loosely plugged-in cables can cause speed loss and instability—issues that are often mistaken for Wi-Fi problems.

These steps don’t require any special knowledge, take very little time, and in many cases can noticeably speed up your Wi-Fi. If things improve after these actions, the problem was likely with the basic network conditions—not your internet plan or serious hardware limitations.

If your Wi-Fi is fast and stable near the router but slows down or becomes unstable in distant rooms, the issue is usually with coverage—not your plan or settings. In this case, boosting the signal or expanding the network can give a real improvement in Wi-Fi speed.

The most effective solution for large apartments and private houses is a mesh system. These consist of several nodes that create a single network with one name, automatically handing off your device from one node to another as you move around. This keeps your speed and connection stable without manual switching. Mesh systems cost more than regular routers, but they deliver noticeably better coverage and convenience.

Alternatively, you can use repeaters. These devices receive the signal from your main router and extend it further. This can help expand your coverage area, but there’s a trade-off: for wider coverage, you sacrifice network speed. As a result, repeaters are better suited for basic network access throughout an apartment, rather than for achieving high speeds.

You can also use a second router set to access point mode instead of a repeater. If you’re able to run a network cable, this option provides stable speed and a reliable connection in distant parts of your home. In this setup, the second router doesn’t create a separate network—it simply extends your existing one by receiving the internet via cable.

The best way to improve coverage depends on your layout, square footage, and speed requirements. If your main goal is stable Wi-Fi throughout your entire home, a mesh system remains the most reliable choice. For boosting the signal in just one room, a repeater is usually enough.

Depending on the band, 2.4 GHz and 5 GHz have different channel selection features.

In the 2.4 GHz band, there are really only three non-overlapping channels: 1, 6, and 11. These channels are commonly used in home networks, and their congestion can seriously affect your connection quality. It’s best to pick one of these channels to minimize interference. However, keep in mind that other devices—like microwaves or Bluetooth gadgets—can also cause interference and impact signal stability.

The 5 GHz band offers many more available channels, making it easier to reduce network congestion. However, automatic router settings often get it wrong and pick crowded channels. This happens because routers don’t always accurately assess how busy each channel is. That’s why it’s a good idea to periodically check which channels are occupied and manually select the least crowded one.

To figure out which channels are busy and pick the most open one, you can use different tools:

Setting up your router correctly can make a big difference in network performance and lower your latency.

Channel width determines how much data can be transmitted over Wi-Fi on a given frequency. The recommended channel width differs for 2.4 GHz and 5 GHz bands:

For most modern devices, it’s recommended to disable “mixed mode” on your router, as it can reduce performance. If all devices on your network support newer Wi-Fi standards (such as 802.11n/ac/ax), turning off “mixed mode” can help improve connection quality.

Enabling WMM (Wi-Fi Multimedia) optimizes data transmission for multimedia applications like video streaming and gaming. With WMM enabled, these applications get higher priority for a more stable connection.

If you don’t have any older devices that require 802.11b/g protocols, you can disable them to increase speed and stability. These older protocols significantly slow down the network, while modern devices support much faster standards.

There are several reasons why your Wi-Fi might slow down in the evening, and most are related to network congestion:
