Connecting to a Wi-Fi network ByFly on a smartphone seems like a simple task - until you encounter errors like "Authentication failed" or "Saved, but no internet access"Problems arise for both newbies and experienced users: the router isn't assigning an IP address, the phone isn't seeing the network, or the password is entered correctly, but the connection still drops. In this article, we'll look into these issues. all current connection methods To ByFly on Android And iOS, including bypassing typical errors and manually configuring network settings.

Peculiarity ByFly As a provider, some plans use MAC address binding and dynamic IP allocation via DHCP. This means that even if you enter the password correctly, the network may block your device if its MAC address isn't registered in your account. We'll take these nuances into account and show you how to work around them. We'll also explore why a simple router reboot sometimes helps, while sometimes resetting your phone's network settings is necessary.

Let's clarify right away: these instructions are valid for all modern router models. ByFly (including Sercomm H500-s>, Huawei HG8245H And ZTE ZXHN H268A), as well as for smartphones on Android 10+ And iOS 14+If you have older equipment, some menu items may differ, but the general connection logic remains the same.

1. Preparing for connection: what to check before starting

Before attempting to connect to Wi-Fi, make sure the problem isn't in the basic settings. Here's 4 key points, which are often missed:

✅ The router is turned on and distributing the networkLook at the indicators: light bulb Wi-Fi (or WLAN) should be green or blue, not flashing red. If the light goes out, check the power supply and cables.

✅ Net ByFly Visible in the list. Open the Wi-Fi settings on your phone and make sure the network is visible. If it's not visible, the SSID broadcast mode (hidden network) may be disabled or the router may have been reset to factory settings.

✅ The Wi-Fi password is knownBy default, it is indicated on the router sticker (field Wi-Fi Key or Password). If the password has been changed, check with the person who set up the network.

✅ No MAC address restrictionsSome tariffs ByFly Require device MAC addresses to be registered in your personal account. If you connect a new phone, its MAC address may be blocked.

⚠️ Attention: If you rent a router from a provider, its firmware may block connections from other devices. In this case, you'll need to whitelist your phone's MAC address through your personal account. ByFly or call support.

If even one of these steps is not completed, the connection will fail. For example, many users try to enter the password, not realizing that the router isn't distributing Wi-Fi at all due to a glitch. Or they enter the password incorrectly because they mix up the characters. l (el) and 1 (unit) on the sticker.

2. Standard connection via phone settings

The most obvious way is to connect via the Wi-Fi menu. Let's look at the process for Android And iOS separately, since the interfaces are different.

On Android

1. Open Settings → Wi-Fi (on some phones the path may be Settings → Connections → Wi-Fi).

2. Find the network in the list ByFly (usually its name starts with ByFly_ or HOME-XXXX).

3. Tap on the network and enter the password. If the field Show password active - turn it on to avoid typing errors.

4. Click Connect.

If the password is correct, the Wi-Fi icon will appear in the notification bar within a few seconds. If not, the system will display an error (we'll discuss these in Section 5).

On iOS (iPhone/iPad)

1. Go to Settings → Wi-Fi.

2. Select a network ByFly from the list.

3. Enter the password and press Connect in the upper right corner.

4. Wait until a check mark appears next to the network name.

On iOS There's one peculiarity: if the network was previously connected but is now down, the system may automatically try to connect without displaying an error. In this case, forget the network and reconnect: 

Settings → Wi-Fi → [Tap the "i" next to ByFly] → "Forget this network"

Make sure the router is turned on and distributing Wi-Fi.

Check the visibility of the ByFly network in the list

Enter the password correctly (it’s better to copy it from the sticker)

Restart your phone if the connection fails-->

3. Connection via QR code (if supported)

Many modern routers ByFly (For example, Sercomm H500-s) support QR code connection. This is convenient if you don't want to manually enter a long password. Here's how it works:

1. Find the QR code on the router sticker (usually next to the SSID and password).

2. On your phone, open the camera and point it at the code. Android you may need to use an app Google Lens, on iOS - standard application Camera.

3. After scanning, a notification will appear prompting you to connect to the network. Confirm your action.

If the QR code does not work:

  • 🔹 Make sure the code is not damaged and is well lit.
  • 🔹 Make sure the QR scanning feature is enabled in your camera settings.
  • 🔹 On older phones, you may need to install a third-party scanning app (e.g. QR Code Reader).

Important: The QR code contains not only the password but also the encryption type (WPA2/WPA3). If the router is configured for WPA3 and your phone doesn't support it, the connection will fail—you'll have to change the security settings in the router's admin panel.

4. Manually adding a network (if ByFly is not displayed in the list)

If the network ByFly is not visible in the list of available ones, this may mean:

  • 📡 Network is hidden (SSID broadcast is disabled).
  • 📶 The signal is too weak (for example, you are far from the router).
  • 🔄 The router is in the "Security Mode" mode. 5 GHz, but your phone doesn't support it.

In this case, the network can be added manually:

On Android

1. Go to Settings → Wi-Fi → Add network.

2. Enter:

  • 📛 Network name (SSID): the exact name (eg ByFly_1234).
  • 🔐 Security type: usually WPA2-PSK or WPA/WPA2-PSK.
  • 🔑 Password: from the router sticker.

3. Save the settings and try to connect.

On iOS

1. Open Settings → Wi-Fi → Other network.

2. Enter the same details as for Android.

3. Click Connect.

If the network still does not connect, check:

  • 🔌 Correctness of the entered information SSID (case important!).
  • 📡 Distance to the router (try getting closer).
  • 🔄 Router operating mode (if it only works in 5 GHz, and the phone only supports 2.4 GHz, connection is impossible).
⚠️ Attention: On some routers ByFly the function is enabled by default Wi-Fi Isolation (Client Isolation). This means that devices on the same network will not "see" each other. If you need your phone to be able to exchange files with your computer via Wi-Fi, disable this option in the router settings (section Wireless → Advanced).

5. Common connection errors and their solutions

Even if you've done everything correctly, errors can still occur. Let's look at the most common ones and how to fix them.

Error Possible cause Solution
Authentication failed Incorrect password or security type Check the password on the router sticker. If that doesn't help, change the encryption type in the router settings to WPA2-PSK.
Received an IP address, but no internet Problems with DHCP or MAC filtering Restart your router. If that doesn't help, register your phone's MAC address in your account. ByFly.
The network is saved, but the connection is not established. Weak signal or incompatible Wi-Fi standards Move closer to the router. If that doesn't help, change the Wi-Fi channel in the router settings (for example, from Auto on 6).
Limited access (on Windows when sharing from a phone) IP address conflict Disable Internet sharing from your phone or set up a static IP manually.

If none of the solutions helped, try reset network settings on your phone:

  • 📱 On Android: Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
  • 🍎 On iOS: Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.

This will delete all saved networks, but often solves connection problems.

🔹 Turn off the mode 802.11r (Fast Roaming)This feature speeds up reconnection between access points, but it can cause glitches on some phones. Find it in Settings. Wireless → Advanced and deactivate.

🔹 Update your router firmwareOutdated software may contain errors that prevent connection. Check the current version in your personal account. ByFly or on the router manufacturer's website.

🔹 Set up DHCP reservationsIf your phone frequently loses connection, reserve a permanent IP address for it. To do this:

  1. Find out the MAC address of your phone (Settings → About phone → General information → Wi-Fi MAC address).
  2. In the router panel, go to DHCP → Address Reservation.
  3. Add a new rule by specifying the phone's MAC and the desired IP (for example, 192.168.1.100).
⚠️ Attention: Router settings may vary depending on the model and firmware version. If you're unsure, it's best to contact support. ByFly or use the "Equipment Setup" service (usually free for subscribers).
