In today's digital world, stable internet access is a basic need, comparable to electricity or water. Provider subscribers Rostelecom often encounter a situation where the speed stated in the tariff plan does not correspond to the actual performance when using a wireless network. Diagnostics The problem begins with precise measurements, which allow us to understand where the bottleneck lies: in the provider's equipment, in the router settings, or in interference in the premises itself.
Using a mobile phone for testing is the most accessible and quick way to obtain objective data on signal quality. Unlike a desktop computer, a smartphone allows you to move around your home, identifying areas of poor reception or "dead zones" where the signal is weak. WiFi becomes unstable. It's important to understand that the speed received from your provider may differ significantly from what your device receives over the air.
In this article, we'll take a detailed look at the process of measuring connection parameters, review the best online tools for this purpose, and analyze the factors that influence the final figures. You'll learn how to distinguish theoretical limit channel and the actual bandwidth available to your gadget at the current moment in time.
Preparing your smartphone and network for testing
Before running any tests, it is necessary to exclude external factors that may distort the results. Background processes Phones often consume bandwidth without the user's knowledge: cloud photo syncing, app updates, or downloading large files can consume up to 80% of the phone's bandwidth. This will lead to incorrect, understated meter readings.
To obtain clean data, we recommend temporarily disabling your mobile internet (3G/4G/LTE) so that testing is performed exclusively via WiFi. You should also ensure you are in close proximity to the router, ideally within 1-3 meters of any physical barriers. Signal At such a distance it will be as powerful as possible, which will allow us to evaluate the equipment's limits.
It's important to check which frequency network you're connected to. Modern routers Rostelecom (for example, series RT or Sagemcom) Two networks are often used: 2.4 GHz and 5 GHz. For accurate maximum speed measurements, the 5 GHz band is preferable, as it is less noisy and has a wider bandwidth.
⚠️ Attention: If your router assigns networks with the same name (SSID) for both frequencies, your phone may automatically switch between them depending on signal strength. For a cleaner experiment, it's best to temporarily separate the network names in your router settings or force the 5 GHz network to be used in your smartphone's WiFi settings.
Popular online speed testing services
There are many resources that allow you to measure connection parameters directly in your mobile phone's browser. The most well-known and authoritative tool is Ookla SpeedtestThis service automatically selects the optimal server for connection, minimizing the impact of distance to the provider's node on the result.

Step-by-step instructions: how to take measurements
The measurement process doesn't require any special technical knowledge, but following the steps carefully ensures reliable results. First, open a browser on your smartphone (Chrome, Safari, or Yandex Browser) and navigate to the selected testing site. Make sure other devices on the network (TVs, tablets, or computers) aren't consuming heavy traffic.
Click the "Go" or "Start Test" button. The service will send and receive data packets for 10-30 seconds. During this time, do not switch between apps and try not to move your phone abruptly to avoid triggering switching between access points if you have multiple. The system will first measure Ping (response time), then download speed (Download) and finally upload speed (Upload).
☑️ Checklist before measuring
After completing the test, you will receive three main values. Please note the units of measurement: providers (including Rostelecom) indicate speed in megabits per second (Mbps), while some downloaders may show megabytes per second (MBps). The difference between them is eightfold: 1 MBps = 8 Mbps. This is a common cause of misunderstandings between subscribers and technical support.
Why is the download speed in the browser slower than in the test?
Browsers and torrent clients often display speeds in megabytes (MB/s), while providers and speed tests use megabits (Mbps). To get your actual download speed, divide your plan's figure by 8. For example, a 100 Mbps plan will give you approximately 12.5 Mbps download speed.
Results Interpretation: Ping, Download, Upload
The obtained figures require correct interpretation. Ping (or response time) indicates how many milliseconds it takes for a signal to reach the server and return. For comfortable surfing and video viewing, a ping of up to 40-50 ms is considered excellent. For online gaming, a ping of up to 20 ms is critical; higher values will result in lag and control delays.
Parameter Download (Download) is the speed at which data is received from the internet. This determines how quickly pages open, images appear, and the quality of video you can watch without buffering. If your plan is 100 Mbps, but the test shows 15-20 Mbps on WiFi, the problem is either hardware or interference.
Parameter Upload Upload speed (upload) characterizes the speed of data transfer from you to the network. This is important for video calls (Zoom, Skype), sending large files to the cloud, or streaming. Upload speeds from providers are typically lower than download speeds, but they shouldn't be critically low (less than 5-10 Mbps for modern plans).
| Parameter | Standard for WiFi | Impact on the user |
|---|---|---|
| Ping | 10-40 ms | Game responsiveness and website loading speed |
| Download | 80-90% of the tariff | Video quality, file downloads |
| Upload | 30-50% of the tariff* | Video calls, photo/file uploading |
| Jitter | < 10 ms | Connection stability (important for VoIP) |
Factors that reduce WiFi connection speed
Even if the provider Rostelecom While the Wi-Fi network delivers full bandwidth to the apartment, it may only reach the phone in a reduced form. Physical obstacles are the primary enemy. Load-bearing concrete walls, mirrors, aquariums, and even the foliage of houseplants can significantly attenuate the signal. Microwave ovens and Bluetooth devices create interference in the 2.4 GHz band.
The second factor is airtime congestionIn apartment buildings, dozens of neighboring routers operate on the same channels, creating a "mess" of radio signals. This leads to increased packet loss and the need to retransmit data, which is visually noticeable as a drop in speed.
The third factor is the technical limitations of the router itself. Older models, even if they were issued by the provider several years ago, may not support modern encryption and speed standards (for example, they are limited by the standard 802.11n instead of 802.11ac or ax). The class of network adapter in your phone also plays a role: budget smartphones often have single-stream WiFi modules, which physically cannot deliver more than 40-50 Mbps.
- 📡 Distance: Each distance from the router reduces the signal level.
- 🏢 Neighbours: Multiple networks on the same channel create interference.
- 📱 Phone hardware: The old WiFi module limits the maximum speed.
- ⚙️ Router settings: Incorrectly selected channel or bandwidth.
⚠️ Attention: Personal account interfaces Rostelecom Router models are updated periodically. If you don't find the settings described below, please refer to the official documentation for your specific device model or use the "My Rostelecom" app, where some diagnostic features are available automatically.
What to do if the speed is significantly lower than the tariff
If, after all the tests, you find that your performance is consistently low, you need to perform some optimization steps. The first step should be changing the WiFi channel. Go to your router settings (usually at 192.168.1.1 or 192.168.0.1) and in the wireless network section, try changing the channel from "Auto" to a specific available number (e.g., 1, 6, or 11 for 2.4 GHz). For 5 GHz, it's best to use channels above 100, if supported.
It's also worth checking if speed limiting (QoS) is enabled in your router settings. Sometimes the traffic prioritization feature is configured incorrectly and artificially throttles the speed of the primary device. If you're using the 2.4 GHz band, try increasing the channel width to 40 MHz, but only if the airwaves aren't too noisy; otherwise, interference will increase.
If software solutions don't help, the problem may be hardware-related. Try connecting your phone to the router via cable (using a USB-LAN or USB-C-Ethernet adapter) to eliminate the possibility of interference from the radio channel. If the cable speed matches your plan's speed, but not via WiFi, and reconfiguring channels doesn't help, it might be time to upgrade to a more modern dual-band router that supports the standard. WiFi 6 (802.11ax).
Can a virus on a phone slow down the internet?
Theoretically, yes, if malware is using your device as part of a botnet to send spam. However, in 99% of cases, the cause of low speed is the radio channel, distance, or hardware limitations, not viruses.
Frequently Asked Questions (FAQ)
Why is the speed on the phone lower than on the computer via cable?
WiFi is a half-duplex transmission medium, meaning a device cannot simultaneously receive and transmit a signal on the same frequency. Furthermore, the signal loses strength when passing through air and walls. A 20-40% speed loss when switching from cable to WiFi is a completely normal physical characteristic of wireless networks.
Does the number of connected devices affect the speed of one phone?
Yes, it does have a direct impact. The channel's bandwidth is divided between all active users. If one TV is watching 4K video and the other is downloading updates, your phone will only have the remaining bandwidth, which will result in a drop in speed during tests.
Do I have to pay for a speed test?
No, all the mentioned services (Speedtest, Fast.com, etc.) are free for the end user. Rostelecom They also don't charge for access to diagnostic tools. If you're asked to pay for "speedup" or "checkup," you're dealing with scammers.
Can weather affect home WiFi speed?
Severe thunderstorms, magnetic storms, or very high humidity can theoretically impact the quality of the radio signal, but in a city apartment, this effect is minimal. Most often, weather-related issues affect the provider's backbone lines, not the internal Wi-Fi network.
How often should I check my internet speed?
It's sufficient to do this when signing up for a new plan, purchasing a new router, or if you encounter any network issues. Continuous monitoring isn't required, as data can fluctuate depending on the time of day and the load on the provider's network.
