4. Connect to a hidden Wi-Fi network

Some routers are configured not to broadcast the network name (SSID). This is done for additional security, but it makes connecting new devices more difficult. To connect to such a network on your phone:

On Android:

1. Go to Settings → Wi-Fi.
2. Click Add a network (or Other networks).
3. Enter the network name (SSID) manually.
4. Select the security type (WPA2/WPA3 or another, depending on the router settings).
5. Enter the password and save.

On iPhone:

1. Open Settings → Wi-Fi.
2. At the bottom of the list, click Other....
3. Please specify Network name (SSID).
4. Select Security (usually WPA2 or WPA3).
5. Enter your password and click Connect.

If you don't know the SSID or security type, you can find this information:

• 🖥️ On a computer already connected to this network (via Control Panel → Network and Internet → Network and Sharing Center on Windows).
• 📋 On the router sticker (usually the default SSID is indicated, for example, TP-Link_1234).
• 🔧 In the router's web interface (address type 192.168.0.1 or 192.168.1.1).

5. Connection Optimization: How to Speed ​​Up Wi-Fi on Your Phone

Even if Wi-Fi is turned on and connected, speeds may be slow. Here are some ways to improve performance:

• 📶 Range selection. Modern routers support two ranges: 2.4 GHz (larger radius, but lower speed) and 5 GHz (higher speed, but smaller radius). Android You can manually select the range in the network settings. iPhone The device automatically connects to the optimal range.
• 🔄 Change channel. If there are many networks in your area 2.4 GHz, they may be causing interference. Go to your router settings and change the channel to a less crowded one (for example, 1, 6, or 11).
• 🛡️ Disabling VPN. If you're using a VPN, it may be slowing down your speed. Try disabling it in your settings (Settings → Network & Internet → VPN on Android).
• 📱 Firmware update. Outdated software may contain bugs that affect Wi-Fi performance. Check for updates in Settings → System → System Update.

It is also worth paying attention to DNS serversBy default, your ISP's servers are used, but they aren't always optimal. To change them:

1. On Android: go to Settings → Wi-Fi, hold your finger on your network, select Change Network → Advanced → IP Settings and install StaticIn the field DNS 1 enter 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
2. On iPhone: Settings → Wi-Fi → (i) next to the network → Configure DNS → Manual and add the same addresses.

6. Security: How to connect to Wi-Fi without risks

Public Wi-Fi networks (in cafes, airports, hotels) are convenient, but often unsafe. Hackers can intercept traffic or create fake access points. Follow these rules to protect your data:

• 🔒 Use a VPN. A reliable VPN (for example, ProtonVPN or NordVPN) encrypts all traffic. Enable it before connecting to public Wi-Fi.
• 🚫 Avoid important operations. Do not log into online banking, do not pay for purchases, and do not enter social network passwords in public networks.
• 🔍 Check the network name. Fraudsters may create a network with a name similar to the official one (for example, Starbucks_Free instead of Starbucks_WiFi). Please confirm the correct name with the staff.
• 📱 Disable automatic connection. On Android disable the option Auto-connection to open networks in the Wi-Fi settings. iPhone — Auto-connection in the network profile.

If you frequently use public Wi-Fi, consider using mobile Internet (4G/5G) instead of connecting to unfamiliar networks. Modern plans offer sufficient data for most tasks.

⚠️ Attention: On Android 10+ And iOS 14+ There's a "Private MAC Address" feature that randomly changes your device's MAC address when connecting to Wi-Fi. This makes it harder to track your phone, but it can cause problems with some routers (for example, those in hotels that require MAC authentication). If necessary, disable this option in your network settings.

7. Diagnosing Wi-Fi problems: When to call for service

If none of the suggested methods help, the problem may be hardware-related. Here are some signs that indicate you should contact a service center:

• 📵 Wi-Fi does not turn on even after resetting the settings.
• 🔌 The phone doesn't detect it not a single one network, although other devices connect normally.
• 🔥 The Wi-Fi module gets very hot (this may indicate a short circuit).
• 🛠️ A message appears on the screen Wi-Fi error or Failed to enable WLAN.

The cost of repairing a Wi-Fi module depends on the phone model:

• For iPhone — from 3,000 to 8,000 rubles (depending on the model and type of module).
• For Android- smartphones - from 1,500 to 5,000 rubles.

Before visiting the service:

1. Back up your data (in case a hard reset is needed).
2. Check if the service provides a repair warranty.
3. Check reviews about the workshop, especially if it's an unofficial service.
