Connection issues: why your smartphone can't see the network or connect

Many people are familiar with the situation where a device can't find a network or constantly asks for a password. The causes can be either router-related or smartphone-related. Let's look at the most common ones.

1. The router does not broadcast the network

• 🔌 Check if the router is plugged into a power outlet and if the power indicator is on.
• 📡 Make sure the button Wi-Fi on the router body is pressed (on some models it may be off).
• 🔄 Reboot your router by unplugging it for 30 seconds.

2. Incorrect network settings

• 🔒 The password was entered incorrectly (check the case of the letters and symbols).
• 📶 The network operates in the range 5 GHz, and your smartphone does not support it (relevant for older devices).
• 🛡️ Filtering is enabled on the router MAC address, and your device is not whitelisted.

3. Problems with your smartphone

• 📱 Mode enabled On the plane - it disables all wireless modules.
• 🔋 Power saving mode may limit performance Wi-Fi.
• 🛠️ Adapter failure - try resetting network settings (more on that below).

If none of these steps help, try connecting to the network from another device (laptop, tablet). If the problem persists, the issue is with the router or ISP. If the other device connects normally, the problem is with your smartphone.

What should I do if my smartphone connects to the network, but the internet doesn't work?

1. Check if the router is turned on parental control or time limits.

2. Make sure your provider isn't blocking access (sometimes authorization through your personal account is required).

3. Try specifying it manually DNS-servers (for example, 8.8.8.8 And 8.8.4.4 from Google) in the network settings on your smartphone.

4. Restart your router and smartphone at the same time.

Choosing the Optimal Band: 2.4 GHz vs. 5 GHz

Modern routers support two frequency ranges: 2.4 GHz And 5 GHzWhich one should I choose for maximum speed and stability?

When to choose 2.4 GHz:

• 🏠 If you are far from the router or there are several walls between you.
• 📱 You have an old device that does not support 5 GHz.
• 🌐 Maximum compatibility with smart devices (lamps, sockets, etc.) is required.

When to choose 5 GHz:

• 🚀 High speed required (streaming video, online gaming).
• 🏢 There are many networks in an apartment building 2.4 GHz, creating interference.
• 💻 Your smartphone supports the standard Wi-Fi 6 (802.11ax).

Important: Some routers combine both networks under one name (SSID). In this case, the smartphone automatically selects the range, but not always optimally. To force a connection to 5 GHz, separate the networks in the router settings by assigning them different names (for example, MyWiFi_2G And MyWiFi_5G).
