Slow connection speeds are often a source of irritation, especially when you need to urgently download a large file or conduct a video conference without lag. Owners of equipment from the ByFly provider (a Beltelecom brand) often encounter situations where the advertised speed doesn't match the actual speeds on their devices. This can be caused by a variety of factors, from simple network congestion in the evening to incorrect router settings or physical obstacles.
Before calling technical support or upgrading your plan, it's worth running a diagnostic of your home equipment yourself. Often, the problem lies in small issues that can be easily fixed in minutes. Optimizing WiFi signal — is a process that requires a comprehensive approach, including analyzing the airwaves, checking cables, and configuring the router's software parameters.
In this article, we'll walk you through a step-by-step process to get the most out of your current connection. We'll cover both software settings and physical hardware placement to ensure stable and fast network access for all your devices.
Diagnosing current speed and identifying bottlenecks
The first step should always be an objective assessment of the situation. You can't rely solely on your subjective perception of a "slow" internet connection, as human perception often distorts reality. It's essential to conduct speed tests using specialized services such as Speedtest.net or Fast.com, connecting first via cable and then via WiFi.
If the speed is consistent with the plan's plan via cable, but significantly lower via wireless, the problem lies with the radio channel or router settings. If low speeds are also observed with a wired connection, it's worth checking the condition of the cable coming into the apartment or contacting your provider to have the line checked.
It's important to conduct tests at different times of day, as the load on the provider's network increases in the evening, which can naturally reduce available bandwidth. It's also a good idea to turn off all devices except the test one to prevent background traffic consumption by other devices.
For accurate diagnostics, it is useful to know the difference between megabits and megabytes, since providers indicate speed in Mbps, while file downloaders often show MB/s. Conversion of units measurements will help to avoid false conclusions about the quality of the connection.
Optimal placement of the ByFly router indoors
The physical location of the router plays a critical role in radio wave propagation. A WiFi signal consists of radio waves, which are easily absorbed or reflected by various materials. The ideal location is considered to be the center of the apartment, on an elevated surface, where the signal can spread evenly in all directions.
Avoid placing your router in alcoves, behind televisions, inside cabinets, or near metal objects. Metal and mirrors create a "shielding" effect, blocking the signal, while thick concrete walls with reinforcement can completely block the signal from reaching adjacent rooms.
⚠️ Caution: Placing your router near a microwave oven or a baby monitor may cause strong interference, as these devices operate in the same 2.4 GHz frequency range.
Router antennas also require proper orientation. If your device has removable or rotatable antennas, point them vertically upward for horizontal coverage, or fan them out if the router is on one floor and the devices are on different floors.
Setting up the 2.4 GHz and 5 GHz frequency bands
Modern ByFly routers, such as models Eltex, RT-IX or ZTE, support dual-band operation. The 2.4 GHz band has a longer range, but is heavily congested with neighboring networks and household appliances. The 5 GHz band offers significantly higher speeds, but has a shorter range and is less effective at penetrating walls.
If your device supports 5 GHz, it is highly recommended to switch to this frequency. In the router settings (usually in the Wireless or WiFi) You can separate networks by giving them different names, for example, "Home_24" and "Home_5G." This will allow you to manually select the fastest connection.
The table below compares the ranges' characteristics to help you decide which one to choose for your situation:
| Characteristic | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Maximum speed | Up to 150-300 Mbps (actually less) | Up to 867 Mbps and higher |
| Penetration ability | High (goes well through walls) | Low (walls significantly dampen the signal) |
| Interference level | Very high (many neighboring networks) | Low (channels are freer) |
| Range of action | Big | Smaller |
Usage channel width It also affects speed. In the 2.4 GHz band, it's best to set it to 20 MHz for stability, while in the 5 GHz band, you can safely set it to 40 or 80 MHz for maximum performance.
What is the 802.11ac standard?
This is a modern WiFi standard that operates exclusively in the 5 GHz band. It provides data transfer rates of up to several gigabits per second, which is several times faster than the older 802.11n standard.
Selecting a free WiFi channel
One of the most common causes of slow speeds is multiple routers operating on the same channel. Imagine a multi-lane road where all the cars are trying to travel in the same lane—a traffic jam will result. In WiFi, this is called a collision, and it leads to packet loss and reduced speed.
To find a free channel, you can use mobile analyzer applications, for example, WiFi AnalyzerBy launching this app, you'll see a channel load chart. Your task is to find the channel number that's least used by your neighbors and manually enter it into your router settings.
In the 2.4 GHz band, only channels 1, 6, and 11 are non-overlapping. If you don't want to perform a detailed analysis, try switching to one of these three channels, as the router's automatic channel selection doesn't always work correctly.
☑️ Check WiFi channels
After changing the channel, you need to reboot the router for the changes to take effect. This simple action often works wonders, instantly improving network responsiveness.
Firmware update and factory reset
A router's software, or firmware, controls all its functions. Manufacturers regularly release updates that fix bugs, patch security holes, and, most importantly for us, optimize the radio module's operation. An outdated firmware version can cause instability.
You can check for updates in the router's web interface. This section is usually located in the menu. System Tools or AdministrationSome modern ByFly models can update automatically, but it's best to check the version manually by comparing it with the information on the equipment manufacturer's website.
⚠️ Caution: During the firmware update process, do not unplug the router or interrupt the connection to the computer. This may cause irreversible damage to the device ("bricked").
If the router has been running for several years without interruption, software errors may have accumulated in its memory. A full factory reset (Factory Reset) often helps clear system junk. To do this, press the button Reset on the device body (usually you need to hold it for 10-15 seconds) and configure the network again.
Using a wired connection and repeaters
For stationary devices such as TVs, gaming consoles, or desktop PCs, a cable connection (Ethernet) is always preferable. Cable is immune to radio interference, provides minimal ping, and guarantees the provider's advertised speed without any loss of bandwidth.
If your WiFi signal isn't reaching remote rooms, you don't need to buy a new, powerful router. You can use a repeater (signal extender) or configure a second router as an access point. This will expand your coverage area without losing signal quality in the farthest reaches.
When choosing a cable for connection, it is important to use a twisted pair cable of a category not lower than Cat 5eOlder cable standards may not physically support speeds above 100 Mbps, which will become a bottleneck for your high-speed plan.
Why is Cat 5 cable better than Cat 5e?
Cat 5 cable is considered obsolete and often only supports 100 Mbps. Cat 5e is guaranteed to support speeds of up to 1 Gbps and beyond, which is critical for modern plans.
Frequently Asked Questions (FAQ)
Why does WiFi speed drop in the evening?
In the evening, usually between 7:00 PM and 11:00 PM, the provider's network experiences peak load, as most subscribers return home and begin actively using the internet. Furthermore, neighbors also turn on their routers, which increases the noise level in the air.
Does the number of connected devices affect the speed?
Yes, it does have a direct impact. The WiFi channel is shared between all active devices. If one computer is downloading torrents while others are trying to watch 4K videos, the speed may not be sufficient for everyone. The router also uses CPU resources to service each connection.
Do I need to replace my ByFly router with my own?
This is worth considering if your device is more than 5-7 years old or doesn't support the 802.11ac (5 GHz) standard. A modern router can often provide increased speed and stability, even when using the same ISP plan.
Can weather affect internet speed?
Weather doesn't affect the WiFi signal inside an apartment. However, heavy thunderstorms, snowfalls, or ice can affect the provider's equipment outside or the connection line if FTTB or GPON technology is used, which will indirectly impact speed.
How can I check if my neighbors are stealing my WiFi?
The router interface has a "Client List" or "Wireless Statistics" section. All connected devices are displayed there. If you see unfamiliar MAC addresses, change your WiFi password and use WPA2-PSK or WPA3 encryption.
