The modern smartphone has become the main device for consuming content, and the quality of communication directly affects the comfort of use. Subscribers of the provider Beltelecom often face a situation where the declared speed of the tariff does not coincide with the actual performance on the mobile device. This can happen for many reasons: from interference on the air to incorrect router settings. To understand who is to blame for the “brakes” - the provider or your equipment, it is necessary to carry out competent diagnostics.
The measurement procedure is not as simple as it seems at first glance. Simply launching the app may give erroneous results if there are updates running in the background or if you are far from a hotspot. In this article we will examine, how to check the Internet speed correctly, what nuances should be taken into account when using Wi-Fi networks from ByFly and how to interpret the obtained figures.
Preparing the device for testing
Before starting any test, it is necessary to exclude factors that can artificially lower the indicators. Smartphones based Android often have background processes that consume traffic. Turn off automatic app updates in Google Play and stop synchronizing cloud storage services such as Google Drive or Yandex.Disk.
It is also important to close all third-party applications running in the background. Messengers, streaming services and social networks can silently download media files. For maximum accuracy, it is recommended to put your phone in airplane mode for 10 seconds and then turn on Wi-Fi only. This will allow you to reset old network connections and get a fresh IP address from the DHCP server.
⚠️ Attention: Do not test if other devices (TVs, laptops, tablets) are currently connected to your Wi-Fi network. Any activity on third-party gadgets will divide the channel bandwidth and distort the measurement results.
Make sure that your smartphone is connected to your home network Beltelecomand not to the mobile data of your cellular operator. Sometimes users forget to switch after leaving home. You can check this in the top notification curtain: the Wi-Fi icon should be active, and the 4G/LTE icon should be absent or inactive for data transfer.
☑️ Preparing your smartphone for an honest test
Choosing the right tool for measurement
There are many diagnostic services networks, but not all of them are equally accurate. The most popular and authoritative tool is Ookla Speedtest. It has its own servers around the world, including nodes in Belarus, which allows you to minimize ping delay. The application is available in Google Play and works stably on any versions. Android.
An alternative option is a service from the provider itself or independent platforms like Fast.com from Netflix. However, for subscribers Beltelecom it is best to use servers located geographically close. In the application Speedtest You can manually select a server in Minsk or another large city to eliminate the influence of trunk delays.
For a more in-depth analysis, you can use the built-in tools of the system, although they are less informative. Go to Settings → About phone → Status (the path may differ depending on the shell MIUI, OneUI or ColorOS). The current connection speed is displayed here, but this is only a snapshot, not the result of a load test.
To obtain representative data, take at least three measurements at different times of the day and calculate the arithmetic average. This will smooth out random surges in network load.
The influence of Wi-Fi frequency range on the result
A critical factor is the frequency range on which your router operates ByFly. Most modern models support two bands: 2.4 GHz and 5 GHz. The 2.4 GHz range is subject to strong interference from neighboring networks, microwaves and Bluetooth devices, which significantly reduces the speed.
If your tariff provides for speeds above 50-100 Mbit/s, and you are connected to a 2.4 GHz network, you physically will not receive the declared values. The real ceiling for this range in an apartment building often does not exceed 40-60 Mbit/s. You need to make sure that the phone is connected to a network with a name containing a prefix _5G or similar.
You can check the current connection in the Wi-Fi settings. Click on your network name to reveal detailed information. The “Frequency” field must indicate 5 GHz. If it says 2.4 GHzthere, you need to either switch manually (if the router broadcasts two different networks) or go to the router settings through a browser.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Maximum speed | up to 150 Mbit/s (actually less) | up to 867 Mbit/s and higher |
| Range | High, penetrates walls | Medium, passes obstacles worse |
| Interference level | Very high | Low |
| Support for older devices | All devices | Only modern smartphones |
Remember, that the 5 GHz signal attenuates faster when passing through solid walls. If you conduct the test in a distant room, the result may be lower than expected not because of the provider, but because of the physics of radio wave propagation. In such cases, it is better to move closer to the router for the purity of the experiment.
Interpretation of indicators: Ping, Jitter, Speed
After the test is completed, you will see three main indicators. Download speed shows how quickly you can download files from the Internet. This figure should correspond to your tariff plan Beltelecom. If the tariff is 100 Mbit/s, and you see 90-95 Mbit/s, this is an excellent result, since part of the speed is spent on service protocol headers.
Upload speed is important for those who download videos, conduct video conferences or play online. For home plans, this speed is often limited by the provider and can be significantly lower than the download speed. This is normal practice for asymmetric communication channels.
The most important for comfort is Ping (delay). It is measured in milliseconds (ms) and shows the server response time. For surfing and video, a ping of up to 50-60 ms is acceptable. For online gaming, values below 30ms are critical. Also pay attention to Jitter (ping variation) - the lower it is, the more stable the connection. High jitter causes freezes in games and video twitches.
⚠️ Attention: If your ping to servers in Minsk exceeds 20 ms with a wired connection or ideal Wi-Fi, the problem may not be the channel speed, but an overload of the provider's equipment or a malfunction of the router.
Don't panic if the numbers fluctuate a little from test to test. The network is a dynamic environment. The big picture is important. If the speed is consistently below 70% of that stated in the tariff, then you should sound the alarm and contact support.
High download speed is useless if you have high ping or jitter. For games and calls, stability is more important than maximum throughput.
Typical errors and ways to fix them
Users often complain about low speed, but the problem lies in the settings of the smartphone itself. Some shells Android have a “Wi-Fi Assistant” or “Switch to Mobile Network” function that tries to improve the signal by constantly jumping between networks. Disable this option in the section Settings → Wi-Fi → Advanced.
Another common mistake is using an outdated encryption standard or channel. Go to the router settings (usually address 192.168.1.1 or 192.168.0.1) and check the wireless network operating mode. For the 5 GHz band, it is recommended to set the standard 802.11ac or 802.11ax (Wi-Fi 6), if your device supports it.
- 📶 Rebooting the router: A simple power off of the device for 1 minute often solves problems with NAT table freezing and frees up clogged communication channels.
- 🔌 Cable connection: Check whether the patch cord is tightly inserted into the WAN port of the router. Oxidized contacts can reduce the connection speed to the provider's line by up to 100 Mbit/s, even if the tariff is higher.
- 📱 Updating drivers: On Android, Wi-Fi module drivers are updated along with the system. Make sure you have the latest phone firmware installed.
If all else fails, try resetting the network settings on your phone. This will remove all saved Wi-Fi passwords and Bluetooth settings, but will return the network stack to its factory state. This can be done in the menu Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings.
What to do if the speed is low on only one device?
If the Internet flies on other gadgets, but slows down on a specific phone, the problem is almost certainly in the phone itself. Try to forget the network and connect again. If it doesn’t help, check your phone on another Wi-Fi network (for example, with friends). If it is also slow there, the Wi-Fi module of the smartphone may be faulty.
When to contact Beltelecom support
There is a clear algorithm of actions before calling technical support. First, you must rule out problems on your side: reboot the equipment, check the cables, test the speed on different devices and at different frequencies. Only if the problem persists on all gadgets when connected directly with a cable to the router, does it make sense to write a request.
When contacting the operator, prepare test results. Screenshots from the application Speedtest indicating the time of measurement and the selected server will be a powerful argument. Operators Beltelecom can carry out remote diagnostics of the line and see the signal level on their equipment.
⚠️ Attention: Tariff conditions and technical capabilities of the network may change. If you are using very old equipment (router older than 5-7 years), it may simply not support modern speeds, even if the provider's line is working. In this case, replacing the equipment will solve the problem.
Remember that over a radio channel (Wi-Fi), the provider cannot guarantee 100% speed compliance with the tariff due to external interference. Warranties usually apply to the speed up to the entrance to the apartment (to the router port). Therefore, the ideal test for a claim is to connect the laptop with a cable directly to the provider’s port (bypassing the router), if such a technical possibility exists.
Technical support will be able to help effectively only when you have ruled out all internal causes of the problems: router malfunction, Wi-Fi interference and phone settings.
Frequently asked questions (FAQ)
Why is the speed on the phone lower than on the computer via cable?
This is normal. Wi-Fi is a half-duplex channel with a lot of losses to overcome walls and airborne interference. A loss of 20-30% speed compared to cable in the 2.4 GHz range is standard. In the 5 GHz range, losses should be minimal.
Does the case affect the Internet speed?
Yes, it can. Metallic cases or cases with magnetic clasps can shield the smartphone's antenna, especially if it is located on the top or bottom of the case. To test the speed, it is better to remove the case.
How to check if someone is stealing my Internet?
Go to the web interface of your router ByFly (the address is usually on the sticker below). In the “Wi-Fi Clients” or “Status” section, look at the list of connected devices. If you see an unfamiliar MAC address, change your Wi-Fi password to a more complex one.
Can weather affect Beltelecom speed?
Weather has virtually no effect on fiber optic lines (FTTB). However, if you have an xDSL connection (via telephone cable) or radio access, severe thunderstorms or humidity can degrade the signal quality and reduce the speed.
Why pay for a 500 Mbps tariff if the phone shows less?
High speed is needed not only for one phone. It allows you to simultaneously watch 4K video on your TV, download games on your PC, and work with the cloud on your laptop without slowing down the speed of each device. The total bandwidth is distributed among all gadgets.
