Many home network users are familiar with situations where the internet speed advertised by their provider differs dramatically from the actual speed. We often encounter 4K video content that stops loading, and online games are plagued by lag, even though the plan promises gigabit speeds. Checking Wi-Fi speed in an apartment — This is the first and most important step in diagnosing connection problems, allowing you to understand where exactly the bottleneck lies.
It's important to understand that wireless data transmission is subject to many factors that aren't present in a wired connection. Walls, appliances, neighbors' routers, and even microwave ovens can all create interference, reducing overall channel performance. Speedtest and other popular services only provide a general picture, but for a deeper analysis, it's necessary to consider the specifics of your living space.
In this article, we'll explore proven testing methods that will help you obtain objective data on your network's condition. You'll learn to distinguish between provider issues and your equipment limitations and understand how to correctly interpret the resulting data for further optimization.
⚠️ Attention: Test results can vary significantly depending on the time of day. In the evening, when the load on the provider's backbone is highest, results may be lower than during the day.
Preparing equipment for testing
Before running any tests, you need to make sure that your hardware is ready for the load and does not distort the results. Router It should be operating normally, and it's best to temporarily disable any unnecessary devices that actively consume data. If possible, it's best to take measurements from a device connected via cable to eliminate any radio interference, but for testing Wi-Fi specifically, we'll be using wireless devices.
Make sure your smartphone or laptop is within the range of the access point where you typically experience problems. Frequency range Also plays a critical role: modern routers operate in two bands—2.4 GHz and 5 GHz. To achieve maximum speed, testing should be performed in the 5 GHz band, as it is less noisy and provides a wider data transmission channel.
Close all background apps that may be downloading updates or syncing data to the cloud. Background download This can significantly underestimate the final results, creating the false impression of a slow internet connection. Restarting the router before starting a series of tests is also a useful procedure, clearing the cache and resetting any connection errors.
☑️ Preparing for the speed test

When using online services, if the server is overloaded or physically located far away, the results may be inaccurate. Always run a series of 3-5 tests on different resources to obtain an average and objective result.
Using the Command Line for Professionals
For users who want to get more technical information about connection quality, the operating system's command line is an excellent tool. Windows and macOS have a built-in utility ping allows you to estimate the response time to a remote node and check the channel stability. This won't show you megabits per second, but it will help identify packet loss and latency spikes.
To run the test, open a terminal or command prompt and enter the ping command to a trusted server, such as Google DNS. The command will look like this:
ping 8.8.8.8 -tOnce launched, you will see a stream of responses with the time indicated in milliseconds. Pay attention to the parameter time (or ms). If the values fluctuate between 10 ms and 300 ms, this indicates signal instability, even if the download speed is technically high. It's also worth paying attention to the line Request timed out - These are lost packets that cause pages to freeze and games to tear.
⚠️ Attention: Teamping -tIn Windows, it runs indefinitely until it's forced to stop. To end the test, press the key combinationCtrl + Cin the terminal window.
Additionally, you can use the utility tracert (or traceroute (in macOS/Linux), which will show the entire path your request takes to the endpoint. This helps you understand where network delays are occurring (at the provider or the backbone). Enter the command:
tracert 8.8.8.8How to decipher Ping results?
A ping of up to 40-50 ms for a cable connection and up to 80-100 ms for Wi-Fi is considered normal. If you see values above 150-200 ms, you may be experiencing problems with internet access. Packet loss should be 0%.
Factors Affecting Indoor Wi-Fi Speed
Why are actual speeds often lower than advertised? The answer lies in the physics of radio wave propagation. Wi-Fi signals weaken when passing through obstacles. Brick walls, reinforced concrete, and even mirrors can block or reflect the signal, causing interference. Wall materials play a key role: drywall transmits the signal well, and metal reinforcement in concrete creates a virtually impenetrable barrier.
Another important factor is airborne noise. In apartment buildings, dozens of neighboring routers operate on the same channels, creating a jumble of radio signals. This is especially true for the 2.4 GHz band, which has only 13 channels, and they often overlap. Interference forces your device to wait for the channel to become free before transmitting data, which reduces effective throughput.
Your router's specifications also matter. Older standards, such as 802.11n, physically cannot provide gigabit speeds, even if the provider offers them. The presence of external antennas, support for MIMO (Multiple Input Multiple Output) technology, and channel width affect the final result.
| Influencing factor | Impact on signal | Recommendation |
|---|---|---|
| Thick concrete walls | Strong attenuation (-10..-20 dB) | Use a repeater or mesh system |
| Microwave oven | Strong interference in the 2.4 GHz band | Do not use the internet while the oven is on. |
| Neighbors' routers | Crossing channels, noise | Switch to 5 GHz or a free channel |
| Aquarium with water | Complete blocking of the signal | Do not place the router behind the aquarium |
Results Analysis: Bits vs. Bytes
One of the most common mistakes when checking speed is confusion in units of measurement. Providers indicate speed in their tariff plans in Megabits per second (Mbit/s or Mbps), while browsers and torrent clients show speed in Megabytes per second (MB/s or MB/s). The difference between them is eightfold.
To determine whether your actual speed matches your plan, divide the result obtained in the test by 8. For example, if your plan is 100 Mbps, your maximum download speed will be around 12.5 MB/s. If you see 10-11 MB/s in the downloader, this is a completely normal result, taking into account the protocol overhead.
It's also worth considering the overhead of the Wi-Fi protocol itself. Some bandwidth is always spent on overhead, encryption, and error correction. Therefore, the efficiency of a wireless channel is typically 60-70% of the theoretical speed of the physical connection.
What to do if the speed is low
If after all the tests you find that your speed is significantly lower than advertised, don't rush to change your provider. Start by rebooting your router and checking your cables. Sometimes the problem can be solved by simply switching to a different, less congested channel in your wireless network settings. Log into your router's admin panel (usually at 192.168.0.1 or 192.168.1.1) and try changing the channel from "Auto" to fixed.
If the problem is only observed in distant rooms, consider installing an additional access point or a modern Mesh systemsIt will create a single, seamless network throughout your entire apartment, automatically switching devices to the closest point with the best signal. Older repeaters often cut speeds in half, making Mesh a preferable solution for larger areas.
Don't forget to update your router firmware. Manufacturers regularly release updates that improve stability and compatibility with new devices. You can check for a new version in the section System Tools → Software Update.
⚠️ Attention: Router settings interfaces may vary depending on the model and firmware version. If you're unsure, it's best to contact the manufacturer's technical support.
