How to Set Up Wi-Fi ByFly on an Android Phone: A Complete Photo Guide

Connecting to home Internet ByFly via Wi-Fi on a smartphone Android It seems like a simple task—until you encounter authentication errors, "limited connection," or sudden loss of signal. The problem is that the provider uses a non-standard authorization scheme (PPPoE over Wi-Fi), which requires manual entry of the login and password for the personal account. This distinguishes ByFly from most operators, where it is enough to simply select the network and enter the router password.

In this article we will analyze all setup methodsFrom a basic router connection to manually creating a PPPoE connection (if the automatic method doesn't work). We'll also cover common errors, such as when a phone "sees" the network but doesn't connect, or when speeds drop after a firmware update. Android. The instructions are valid for all OS versions (from Android 8.0 to Android 15) and any smartphone models: Samsung Galaxy, Xiaomi Redmi, HONOR, Realme and others.

Let us warn you right away: if you use Public Wi-Fi from ByFly (for example, in a cafe or hotel), the settings will be different - they usually use captive portal authorization. This article is dedicated exclusively to home connection via a personal router.

1. Preparation: What you need to know before setting up

Before you begin connecting, please check three key points:

• 📋 ByFly account login and passwordThis isn't a Wi-Fi password, but rather the login information for your provider's system (usually found in your contract or receipt). If you've lost it, you can recover it through personal account or call support.
• 📡 Router model. U ByFly devices are often used Sercomm RV6699, Huawei HG8245H or ZTE ZXHN H267NDepending on the model, it depends on whether you need to configure PPPoE on your phone or if the router does this automatically.
• 🔄 Router operating mode. If it is turned on Bridge (bridge), then authorization will have to be completed on each device separately. In the mode Router (router) it is enough to connect to Wi-Fi as to a regular network.

A common mistake users make: trying to connect to Wi-Fi ByFly the same as to the network MTS or A1 — simply by selecting the SSID and entering the router password. This will only work if the router is already configured for automatic authentication (automatic authentication mode). Router). Otherwise, it will be necessary manual PPPoE setup directly on the phone.

⚠️ Attention: If you rent a router from ByFly, its default settings are usually already optimized for automatic connection. Problems most often arise with personal routers (for example, TP-Link or ASUS), connected to the provider's network.

2. Method 1: Connecting to Wi-Fi in Router mode (the easiest)

If your router is configured in mode Router (This can be clarified in your personal account ByFly (or on the device sticker), then the Wi-Fi connection is no different from the standard one:

1. Open Settings on the phone.
2. Go to the section Wi-Fi (or Network and Internet → Wi-Fi on new versions Android).
3. Turn on Wi-Fi and select the network with the name of your router (for example, ByFly_1234 or HOME-ABCD).
4. Enter your Wi-Fi password (indicated on the router sticker or in the contract) and press Connect.

If after connecting, the internet icon (🌐) appears in the status bar and websites open in the browser, the setup is complete. If the connection is "limited" or websites don't load, proceed to Method 2 (manual PPPoE setup).

Wi-Fi is active (📶 icon in the notification bar)

Any website (for example, google.com) opens in the browser.

Download speed matches the plan (check on speedtest.net)

There are no exclamation marks next to the network name-->

On some phones (eg. Xiaomi or Samsung with shell One UI) After connecting, a notification “Additional configuration required” may appear. This means that the router is operating in the “Additional configuration required” mode. Bridge, and you need to create a PPPoE connection manually.

3. Method 2: Manually create a PPPoE connection on Android

If the router is operating in mode Bridge (bridge), then authorization in the network ByFly Each device must be tested separately. To do this, you need to create an account on your phone. PPPoE tunnelThe instructions vary depending on the version. Android:

4. Troubleshooting: Why ByFly Wi-Fi Won't Connect

Even after proper setup, errors may still occur. Let's look at the most common ones and how to fix them:

Authentication or Incorrect Password Error

Reasons and solutions:

• 🔑 Incorrect login/password: check the case (login is case sensitive!). For example, Ivanov@byfly.by ≠ ivanov@byfly.by.
• 🔄 Account blocking: after 3 unsuccessful attempts ByFly may temporarily block access. Wait 10-15 minutes or reboot your router.
• 📡 Incompatible encryption type: in the router settings, change the security type from WPA3 on WPA2-PSK (relevant for older phones).

Connection is "limited" or there is no internet access

Most often this means that:

• 🔌 PPPoE is not connected: Check if the connection is activated in your phone settings.
• 📵 Router in Bridge mode: If you haven't created PPPoE on your phone, the internet won't work.
• 🔍 DNS servers are not responding: Manually enter Google's DNS (8.8.8.8 And 8.8.4.4) in the Wi-Fi settings.

Wi-Fi connects, but the speed is very slow

Possible reasons:

• 📶 Weak signalCheck your Wi-Fi signal strength in your settings. If it's less than 2-3 bars, move your router or use a repeater.
• 🔄 Channel congestion: in the router settings, change the Wi-Fi channel from Auto to a fixed one (for example, 6 or 11 for 2.4 GHz).
• 📱 Restriction from the providerIf your speed drops after connecting multiple devices, check your plan in your personal account. ByFly.

5. Setting up Wi-Fi ByFly on phones without PPPoE support

Some budget phones (eg. Tecno, Infinix or old models Lenovo) do not support creating PPPoE connections. In this case, there are two options:

Method A: Use the router in Router mode

If your router allows it (for example, Sercomm RV6699), switch it from the mode Bridge V Router:

1. Connect to the router via cable or Wi-Fi.
2. Open your router's control panel (usually at 192.168.1.1).
3. Go to the section WAN or Internet.
4. Select connection type PPPoE and enter your login/password from ByFly.
5. Save the settings and reboot the router.

After this, connect to Wi-Fi as you would to a regular network—authorization will occur at the router level.

Method B: Set up PPPoE on another device and share Wi-Fi

If the router does not support the mode Router, use a second phone, tablet or laptop:

1. On a PPPoE-enabled device, create and connect a PPPoE connection (as described in Method 2).
2. Turn it on Wi-Fi hotspot (in settings Network and Internet → Access Point).
3. Connect the main phone to the shared network.

⚠️ Attention: When sharing Wi-Fi via your phone, internet speed may drop by 20-30% due to hardware limitations. For stable performance, use a device with Wi-Fi 5 (802.11ac) support.

6. Optimize Wi-Fi ByFly for maximum speed

Even if the internet is working, its speed may be lower than what's stated in your plan. Here's how to improve your connection:

1. Choosing the right Wi-Fi band

Modern routers ByFly support two ranges:

• 2.4 GHz: Better through walls, but susceptible to interference from neighbors. Optimal for older phones.
• 5 GHz: higher speed, but smaller coverage area. Suitable for newer smartphones (e.g. Samsung Galaxy S22 or Xiaomi 13).

How to choose:

1. Open Wi-Fi settings on your phone.
2. Click on your network name and select Range (if the router supports both).
3. For maximum speed, select 5 GHz, but if the signal is weak, go back to 2.4 GHz.

2. Changing the Wi-Fi channel

If you have many neighbors with Wi-Fi in your home, the networks may interfere with each other. To find a free channel:

1. Install the application WiFi Analyzer (available in Google Play).
2. Run a scan and see which channels are the least crowded.
3. Enter your router settings (192.168.1.1) and in the section Wi-Fi change the channel to a free one (for example, with 6 on 11).

3. Updating the router firmware

Outdated router firmware can limit Wi-Fi speed to 50–70 Mbps, even with a 100+ Mbps plan. To update:

1. Check the current firmware version in the router control panel (section System or Update).
2. Download the latest version from the website ByFly (Support section).
3. Download the firmware via the router's web interface and wait for it to reboot.

7. Security: How to protect your ByFly Wi-Fi

An open or poorly secured Wi-Fi network can become a target for hackers or neighbors who can jam your connection. Basic protection measures:

1. Change the default Wi-Fi password

By default on routers ByFly the password is indicated on the sticker (for example, 12345678). It definitely needs to be changed:

1. Go to your router's control panel (192.168.1.1).
2. Go to the section Wi-Fi → Security.
3. Select encryption type WPA2-PSK (Not WPA or WEP!).
4. Create a complex password (at least 12 characters, with numbers and letters).

2. Disabling WPS

Function WPS (quick connection with PIN) is vulnerable to hacking. Disable it:

1. Find the section in the router panel Wi-Fi → WPS.
2. Disable the option or set the mode Disabled.

3. Filtering by MAC addresses

You can allow connections only to certain devices:

1. Find your phone's MAC address in Settings (About phone → Status → Wi-Fi MAC address).
2. In the router panel, go to Wi-Fi → MAC Address Filter.
3. Add your phone's MAC address to the whitelist.

⚠️ Attention: MAC filtering doesn't provide 100% protection—experienced hackers can spoof MAC addresses. Use it as an additional measure in addition to a strong password.

8. Frequently Asked Questions (FAQ)

Is it possible to connect to ByFly Wi-Fi without a router, directly via cable?

Yes, but you need a phone with a port for this. Ethernet (or adapter USB-C/OTG → Ethernet) and PPPoE support. This method is inconvenient on most smartphones—it's easier to use a router.

Why did Wi-Fi ByFly stop working after updating Android?

The update may have reset your PPPoE settings. Check:

1. Do you go into settings? PPPoE and whether the connection checkbox is active.
2. Have your login/password been reset (sometimes the fields are cleared after an update).
3. Has the phone's MAC address changed (relevant if MAC filtering is used).

If nothing helps, delete the PPPoE connection and create it again.

How do I know if my ByFly router is operating in Bridge or Router mode?

There are three ways:

1. Look at the sticker on the router - if the mode is indicated Bridge, then PPPoE needs to be configured on each device.
2. Log in to your personal account ByFly — the equipment information usually indicates the mode.
3. Connect to Wi-Fi: if the Internet works without additional settings, the router is in mode Router.
