1. Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
2. Enter your password and confirm.

After the reset, all saved networks and passwords will be deleted. You will need to re-enter your home Wi-Fi password.

3.3. Outdated firmware or OS errors

If your phone hasn't been updated in a while, there may be compatibility issues with the Wi-Fi module and the current firmware version. Update your operating system:

• On Android: Settings → System → System Update.
• On iOS: Settings → General → Software Update.

If the update does not help, try rolling back the firmware to the previous version (relevant for Android). To do this:

4. Router Problems: Diagnostics and Settings

If your phone can't detect Wi-Fi, but other devices connect fine, the problem may lie in your smartphone's individual router settings. Let's look at the key settings to check.

4.1. Incorrect Wi-Fi channel

Routers automatically select a channel for broadcasting, but sometimes they choose a congested one, which leads to connection issues. Try manually setting the channel:

1. Log into your router's web interface.
2. Find the section Wireless Settings (or "Wireless Network").
3. Select a channel in the range 1–11 (for 2.4 GHz) or 36–165 (for 5 GHz).
4. Save the settings and reboot the router.

To analyze channel load, use applications like Wi-Fi Analyzer (Android) or NetSpot (iOS/macOS). They will show you which channels are less crowded in your area.

4.2. Inappropriate security type

If the router uses an outdated encryption type (for example, WEP), modern phones may not connect to such a network. Optimal security settings:

• 🔒 WPA2-PSK (AES) — the most reliable and compatible option.
• 🔒 WPA3-PSK — is a new standard, but some older devices do not support it.
• ❌ WEP or Open network - unsafe, not recommended.

To change the security type:

1. Go to your router settings.
2. Find the section Wireless Security (or "Wireless Security").
3. Select WPA2-PSK and enter a password (at least 8 characters, with numbers and letters).
4. Save the settings.

4.3. Limitation on the number of devices

Some routers have a limit on the number of simultaneously connected devices (usually 10-30). If this limit is reached, new devices will not be able to connect. Solutions:

• 📱 Disconnect unnecessary devices from Wi-Fi (old phones, smart bulbs that haven’t been used for a long time).
• 🔄 Restart your router - this will reset the list of connected devices.
• ⚙️ Check your router settings for device restrictions (section DHCP or "Local Area Network").
How do I find out how many devices are connected to my router?

In the router's web interface, find the section Connected Devices, DHCP Clients or "Connected Devices." There will be a list of all devices with their IP and MAC addresses. If the router doesn't display this information, use mobile apps like Fing (Android/iOS).

5. Problems with your provider: when the internet is to blame, not the equipment

Sometimes the problem isn't with your phone or router, but with your internet connection itself. For example, your provider may have temporarily suspended service or changed your connection settings. Here's what to do:

• 📞 Call your provider's support team and check if there are any issues on their end. Ask if any connection settings have been changed (for example, the authorization type). PPPoE, L2TP).
• 🔌 Check if the indicator light is on Internet or WAN On the router. If it's red or blinking unusually, there's a problem with the line.
• 💻 Connect your computer to the router via cable. If the internet isn't working on your PC either, the problem is with your internet provider.

If your provider has confirmed that everything is fine on their end, but the internet still isn't showing up on your router, try:

1. Disconnect the ISP cable from the router and connect it directly to the computer. If the internet works, the problem is with the router.
2. Reset the router to factory settings (button Reset on the back panel, hold for 10-15 seconds).
3. Reconfigure the router from scratch using data from the provider (logins, passwords, connection type).
