Setting up Wi-Fi on a ByFly BY router: from logging into the control panel to network optimization

If you use the Internet from a Belarusian provider ByFly and received a router from him BY-series (for example, BY-RT-4G, BY-RT-Dual or BY-RT-AX1800), setting up a wireless network may seem complicated at first glance. Unlike all-in-one routers, ByFly equipment often comes with pre-activated settings, but it's still worth checking them—especially if speeds are poor or the network drops out intermittently.

In this article we will look at all stages of Wi-Fi configuration — from basic router connection to fine-tuning settings like channel selection, enabling a guest network, and updating firmware. We'll also cover common errors (such as devices not seeing the network or connecting but not connecting to the internet) and troubleshooting steps. If you're renting equipment from a provider, some settings may be locked—we'll highlight these.

Let's get started with the step-by-step instructions. We'll start with the simplest part: how to access the router control panel and find the Wi-Fi settings section.

How to access the ByFly BY router web interface

The first step is accessing the admin panel. To do this, you'll need any device (computer, laptop, or smartphone) connected to the router. via cable (recommended) or via Wi-Fi. If you haven't changed your default login details yet, use the following:

• 🌐 Panel address: 192.168.1.1 or byfly.by (Sometimes 192.168.0.1 - check the sticker on the router).
• 🔑 Login: admin (or user for some models).
• 🔒 Password: admin, password or an empty field. On newer devices, the password may be on a sticker (e.g., BY12345678).

If the default settings aren't working, try resetting your router to factory settings. To do this:

1. Find the button on the back panel Reset (usually recessed into the body).
2. Press it with a paper clip or toothpick and hold it 10-15 secondsuntil the indicators start flashing.
3. Wait 1-2 minutes for the router to reboot.

⚠️ Warning: Resetting will delete all user settings, including the Wi-Fi password, linked devices, and parental control rules. If the router is rented from ByFly, reactivation may be required through support after the reset.

After successfully logging in, you'll see the main page of the web interface. It may look different depending on your router model, but the section Wi-Fi (or Wireless network) is usually located in the top menu or sidebar. If the interface is in English, look for Wireless.

Basic Wi-Fi settings: network name and password

In the section Wi-Fi (or Wireless Settings) you'll find the basic wireless network settings. Here you can:

• 📛 Change network name (SSID): By default it often looks like this BYFLY_XXXX or BY-XXXXWe recommend setting a unique name to avoid confusion between your network and neighboring ones.
• 🔐 Set password: The standard password is usually indicated on the router sticker, but it is worth changing it to a more secure one (at least 8 characters, with numbers and letters).
• 📡 Select network standard: For maximum compatibility, please select 802.11n/ac/ax (mixed mode)If you have older devices (pre-2012), you may need to enable 802.11b/g/n.
• 🔄 Enable/Disable Network: Useful if you need to temporarily suspend Wi-Fi distribution (for example, overnight).

Example of a secure password: ByFly_2026!WiFiAvoid simple combinations like 12345678 or qwerty — they're easy to hack. If you're worried about forgetting your password, write it down in a notepad or a password manager.

After making changes, don't forget to click Save or ApplyThe router will reboot, and all connected devices will be disconnected. To reconnect, use the new network name and password.

Channel Selection and Signal Strength: How to Eliminate Interference

If your Wi-Fi is slow or drops out intermittently, the problem may be channel congestionIn apartment buildings, many routers use standard channels (for example, 6 or 11 in the 2.4 GHz band), which creates interference. To select the optimal channel:

1. Open the section Wireless Settings → Channel.
2. For the range 2.4 GHz Select a channel manually (recommended: 1, 6 or 11 - they do not intersect). For 5 GHz you can leave it Auto.
3. Use apps like Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) to see the channel load of your neighbors.

Also check the setting Transmit Power (transmission power). By default, it is set to 100%, but in a small apartment it's enough 50–75%Reducing power reduces interference to other networks and reduces the router's power consumption.

If you have BY-RT-AX1800 or another model with support MU-MIMO And Beamforming, enable these features in settings. They improve connection stability for multiple devices simultaneously:

• 📶 MU-MIMO: Allows the router to communicate with multiple clients in parallel.
• 🎯 Beamforming: Focuses the signal towards the connected device rather than scattering it in all directions.

⚠️ Warning: In range 5 GHz The signal penetrates walls worse, but is less susceptible to interference. If you have thick concrete partitions, use 2.4 GHz or install a repeater.

Setting up a guest network and parental controls

If you have guests, friends, or colleagues connecting to your Wi-Fi, it's a good idea to create a private area for them. guest networkThis will allow:

• 🔒 Restrict guest access to local devices (printers, network drives).
• 🕒 Set a time or traffic limit.
• 📵 Disable the guest network on a schedule (for example, at night).

To set up a guest network on a ByFly router:

1. Go to Wireless → Guest Network.
2. Turn on the guest network (Enable Guest Network).
3. Specify a name (eg. Ivanov_Guest) and password.
4. In the section Access Control limit your speed (for example, to 10 Mbps) or working hours.

For parental control (access restrictions for children) use the section Parental Control or Access RestrictionHere you can:

• 🕒 Block internet access during certain hours (for example, from 10:00 PM to 7:00 AM).
• 🌐 Block specific websites or categories (social networks, games, torrents).
• 📱 Link restrictions to the MAC address of the child's device.

On some ByFly models (eg. BY-RT-4G) Parental control features are simplified. In this case, use third-party solutions like OpenDNS or settings on the device itself (for example, Screen time on iPhone).

What to do if the guest network is not working?

Make sure the Guest Network setting is enabled. Allow guests to access the Internet. Also check that the IP addresses of the guest and main networks do not conflict (for example, the main network on 192.168.1.0/24, and the guest one is on 192.168.2.0/24).

Firmware update and factory reset

If the router is unstable, periodically freezes, or does not provide the stated speed, the problem may be in outdated firmwareSoftware updates fix bugs, add new features, and improve security.

To update the firmware on your ByFly router:

1. Go to System Tools → Firmware Upgrade.
2. Click Check for Updates (check for updates).
3. If a new version is available, download it and follow the on-screen instructions. Do not turn off the router during the update!

If the automatic update does not work, download the firmware from the official ByFly website (section Support) and download it manually via Manual UpgradeMake sure you select the file specifically for your router model!

If after updating or changing the settings the router stops working, follow these steps: hard reset (as described in the first section). After that:

• Connect to the router via cable.
• Enter the standard login/password (admin/admin).
• Re-configure your Internet connection (connection details are usually specified in your ByFly contract).

⚠️ Note: On rented ByFly routers firmware update may be blocked provider. In this case, please contact technical support by phone 123 (for ByFly subscribers).
