The causes aren't just related to the settings. router, but also in the parameters of the device itself, firmware versions, and sometimes in physical interference.

In this article, we will analyze the connection process step by step: from choosing the right Wi-Fi standard (802.11ax, 802.11ac or outdated 802.11n) to the finer details of the settings DHCP, encryption, and channels. We will pay special attention to typical errors in Android 14+ And iOS 17+, as well as rare cases when the problem lies in the settings provider (for example, binding by MAC address). If you have already tried to connect, but were unsuccessful, skip the introductory part and go to the section "Problem diagnosis».

For clarity, we will provide screenshots of the interfaces of popular routers (TP-Link Archer AX73, Keenetic Giga, ASUS RT-AX86U) and mobile OS.

You can check these settings through the router's web interface. To do this:

1. Connect to the router via cable or another network.
2. Enter the address in the browser 192.168.1.1 or 192.168.0.1 (the exact address is indicated on the device sticker).
3. Log in (default logins/passwords: admin/admin or admin/password).
4. Go to the section Wireless network (Wireless).

Example settings for TP-Link Archer AX73:

After changing the settings, do not forget to save them (button Save or Apply) and reboot the router. This is a mandatory step—many settings are applied only after a reboot.

1. Go to the web interface (192.168.1.1).
2. Go to Wireless network → Wireless security.
3. In the field PSK password Enter a new key (at least 12 characters, with numbers and special characters).
4. Save the settings and reconnect all devices.

Additional measures:

• Create guest network For friends, this isolates their devices from your local network.
• Turn it off Remote control in the router settings (section Administration).
• Update your router firmware to the latest version (via System tools → Firmware update).

How do you know if your Wi-Fi has been hacked?

If your internet speed has dropped sharply for no reason, in the list of connected devices (section DHCP or Clients If unknown devices have appeared on your router, or you see suspicious activity in your traffic history, these are signs of unauthorized access. Change your password immediately and check your security settings.

Troubleshooting: Why Your Phone Won't Connect

If after all these steps the phone still doesn't connect, use this table for diagnostics:

Advanced diagnostics:

• 📱 On Android install the application WiFi Analyzer and check the signal level. If it is lower -70 dBm, move the router closer.
• 🖥️ Connect to the router via cable and check the logs (System log or Log). Look for errors like authentication failed.
• 🔧 Reset network settings on your phone: Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
