How to Speed ​​Up Wi-Fi on ByFly: A Complete Optimization Guide

Slow wireless connection speeds are a familiar issue for many ByFly subscribers, especially during peak hours or when using outdated equipment. Users often encounter situations where the advertised plan doesn't match the actual speed they receive on mobile devices or laptops. This can be caused by a variety of factors, from physical obstacles in the apartment to incorrect router settings.

Before calling technical support, it's worth performing a series of diagnostic tests yourself, which in most cases can significantly improve signal quality. Network optimization — this process doesn't require in-depth programming knowledge, but it does require attention to detail. We'll explore effective methods that will help you get the most out of your plan.

In this article, we'll take a detailed look at how to choose the right location for your router, how to configure frequency ranges, and what hidden parameters can affect connection stability. You'll learn why neighboring networks are interfering with your internet connection and how to combat it. Correct configuration equipment can work wonders even without changing your provider or buying expensive gadgets.

Diagnosing current speed and identifying bottlenecks

The first step toward high-speed internet is an objective assessment of your current situation. You can't optimize what you haven't measured. There's a common misconception that the speed displayed in the Windows or Android connection status is the actual internet speed. In fact, it's just an indicator. physical limit interface between the device and the router, which can be 300 Mbps, even if the Internet itself barely manages 10 Mbps.

To obtain reliable data, use specialized services such as Speedtest.net or Fast.com. It's important to test with a device connected via a cable to eliminate the radio channel's influence, and then compare the results with Wi-Fi results. If the difference is significant, the problem lies with wireless data transmission. Otherwise, it's worth checking the line's condition or whether your plan is up-to-date.

Please note the time of day when your measurements are taken. In the evening, when all your neighbors are actively downloading torrents or watching 4K videos, the load on your ISP's nodes increases. Compare speed readings during the day and late at night This will help you determine whether the drop is due to network congestion on your provider's network or problems within your local network. If your speed is excellent during the day but drops significantly in the evening, you might want to consider upgrading to a higher-priority plan.

Optimal placement of a router in an apartment

The physical location of the router plays a critical role in coverage. Radio waves used for data transmission do not penetrate well through metal structures, mirrors, aquariums, and thick concrete walls with reinforcement. The ideal location for installing the device is ByFly router is the geometric center of the apartment, located at a height and in an open space.

Don't hide the router in niches, behind cabinets, or inside weak electrical outlets. Enclosed spaces create a "thermos" effect, where the device overheats, leading to processor throttling and reduced Wi-Fi performance. Furthermore, metal cabinet doors shield the signal, directing it in the wrong direction. Ensure free air circulation around the enclosure.

⚠️ Attention: Avoid placing your router near microwave ovens, baby monitors, or cordless phone base stations. These devices operate in the same frequency range and create strong interference that can completely block the desired signal.

If your apartment is elongated (like a pencil case), a single router may not be enough. In such cases, the signal weakens toward the end of the hallway. A solution may be to use repeaters or set up a mesh system, if your equipment supports it. The antennas on your router are also important: if they are removable, try adjusting their angle. For omnidirectional coverage, it's best to position the antennas vertically.

Setting up frequency ranges: 2.4 GHz vs. 5 GHz

Modern routers provided by ISPs are often dual-band. This means they can broadcast simultaneously on both 2.4 GHz and 5 GHz frequencies. The 2.4 GHz band is the noisiest, as it's used by Bluetooth devices, microwave ovens, and neighbors' Wi-Fi networks. It offers greater coverage but lower speeds.

The 5 GHz band offers significantly higher throughput and less interference. However, it has a significant drawback: it penetrates walls less effectively. If your goal is maximum speed For online gaming or watching high-definition video, and you are in the same room as the router, choose a 5 GHz network.

You can force the operating mode in your router settings. Go to the web interface (usually at 192.168.1.1 or 192.168.0.1) and find the wireless network section. Make sure the channel width is set to 80 MHz for the 5 GHz band and 20 MHz for the 2.4 GHz band (or 40 MHz if the air is clear). A wide channel on 2.4 GHz often causes instability due to interference with neighboring networks.

Channel load analysis and manual switching

One of the most common causes of low speeds is operating on a "busy" channel. Think of a channel as a traffic lane on a road. If all neighbors choose the same lane, a traffic jam occurs, and data transmission is delayed. Routers typically attempt to select a channel automatically, but these algorithms often make mistakes or fail to switch dynamically as conditions change.

To analyze the situation, use mobile applications like WiFi Analyzer or WiFi ManThey will display a graphical map of the airwaves, showing which channels neighboring networks are using. Your task is to find the least congested channel and assign it statically to your router settings. For the 2.4 GHz band, non-overlapping channels are 1, 6, and 11.

After changing the channel, be sure to reboot the router. The changes take effect only after restarting the wireless network service. If the situation worsens after a while (neighbors have also changed channels), you will need to repeat the procedure. Some advanced router models have a feature that automatically selects the least congested channel at system startup.

Firmware update and factory reset

A router's software is the device's operating system. Like smartphones or computers, it can contain bugs that affect stability and data transfer speeds. The manufacturer regularly releases updates that fix bugs and improve Wi-Fi performance. Ignoring updates can result in your equipment operating inefficiently.

You can check for a new version in the router's web interface under "System Tools" or "Administration." If automatic updating doesn't work, you can download the firmware file from the manufacturer's official website (Huawei, ZTE, TP-Link) and upload it manually. Important: Do not interrupt the firmware update process or turn off the router's power at this point, otherwise the device may become bricked.

If the router has been running for several years without interruption, software errors may have accumulated in its memory. A full factory reset (Reset) often helps "shake up" the system. After the reset, you'll have to re-enter your internet connection information (PPPoE or VLAN login and password), but this ensures that configuration debris and conflicts are cleared.

Changing DNS servers to speed up response times

While changing DNS servers doesn't physically increase file download speed (bandwidth), it can significantly speed up page loading and application response times. DNS (Domain Name System) translates human-readable website addresses (e.g., google.com) into IP addresses understandable to computers. ByFly's default DNS servers may be slow or intermittent.

Using public DNS from Google or Cloudflare often solves the problem of browsers taking a long time to load a page. This is especially noticeable on mobile devices and in games, where the speed of the first packet is crucial. DNS can be configured either on the router itself (which will then change for all devices) or on a specific computer or smartphone.

Google DNS Primary: 8.8.8.8
Google DNS Secondary: 8.8.4.4
Cloudflare DNS Primary: 1.1.1.1
Cloudflare DNS Secondary: 1.0.0.1

How to change DNS on Windows?

Open Control Panel → Network and Internet → Network and Sharing Center. Click on your connection, then click Properties. Find Internet Protocol Version 4 (TCP/IPv4) in the list, select it, and click Properties. Select Use the following DNS server addresses and enter the numbers from the table above.

After changing DNS settings, it is recommended to clear the DNS cache on your computer. To do this, open the command prompt and enter the command ipconfig /flushdnsThis action will remove old, possibly incorrect, name-to-IP mapping entries, forcing the system to request fresh information from new servers.

Frequently Asked Questions (FAQ)

Why does Wi-Fi speed drop in the evening?

Evenings (7:00 PM to 11:00 PM) are peak hours, when most subscribers in your home and neighborhood are actively using the internet. The provider's bandwidth becomes congested, resulting in a reduction in available speed for each user. Noise levels in the airwaves also increase due to neighboring routers.

Does the number of connected devices affect the speed?

Yes, it does have a direct impact. A router has limited computing power. If 20 devices are connected to the network, five of which are downloading torrents and the rest are watching videos, the router's processor may not be able to handle the traffic distribution, causing lag and speed drops even on a single active device.

Do I need to buy my own router if ByFly provides its own?

Providers' standard routers are often basic models designed for minimal requirements. If you have a plan higher than 100 Mbps, a large apartment, or many devices, purchasing a modern dual-band router that supports the standard Wi-Fi 6 (802.11ax) can provide a noticeable increase in productivity and stability

Will a signal booster (repeater) help?

A repeater can help increase coverage if the signal is simply lost in a distant room. However, it doesn't increase speed; it actually reduces it slightly (usually by 30-50%), as it needs to receive, process, and transmit the signal. For larger apartments, mesh systems are better.

⚠️ Attention: Router interfaces and provider plans may be updated. If you can't find the setting you're looking for, check the latest instructions on your equipment manufacturer's official website or contact ByFly support.
