However, it's important to proceed systematically: first, rule out external factors (problems with the router or ISP), then check the phone's settings, and only as a last resort should you resort to drastic measures like a factory reset.

In this article - step-by-step diagnostic algorithm Troubleshooting, as well as answers to frequently asked questions. If, after all these steps, your Wi-Fi still isn't working, we'll finally discuss when it's time to call a specialist and how much it might cost.

1. Check the source of the problem: phone or router?

The first thing to do is determine whether the phone itself is to blame Or the problem lies with the router, ISP, or even the power supply. To do this:

🔹 Connect another device to the same Wi-Fi network (laptop, tablet, second phone). If the internet works, the problem is definitely with your device. If not, the router or ISP is to blame.

🔹 Reboot your router. Unplug it for 30 seconds, then plug it back in. Wait until it boots up completely (the indicators should be steady, not blinking). On some models (TP-Link Archer, ASUS RT-AX88U) After rebooting, it may take 1–2 minutes to re-establish the connection with the provider.

🔹 Check your provider's cableIf you have PPPoE-connection or dynamic IP, inspect the network cable for damage. Try connecting it to a different router port (they are usually labeled WAN or Internet).

🔹 Make sure your subscription period has not expired.If you have a prepaid plan (for example, from Rostelecom or Beeline), check your balance in your personal account. Some providers block network access when your balance is zero, but the Wi-Fi network remains visible.

⚠️ Attention: If after rebooting the router the indicator Internet or WAN If the light is flashing orange or not lit at all, the problem is with your ISP. Contact technical support (the numbers are usually listed on the router sticker).

  • 🔒 Check the security type. Make sure that your router settings are set to WPA2-PSK or WPA3-PSK. Outdated WEP may cause problems on modern phones.
  • 📡 Turn off Smart Connect. On some Android-devices (Xiaomi, Realme) There is a function that automatically switches between Wi-Fi and mobile networks. This can interfere with a stable connection. Look for it in Settings → Wi-Fi → Advanced.

🛠 Reset network settings (if the previous steps did not help):

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

After the reset, your phone will lose all saved Wi-Fi passwords, so make sure you have them ready in advance.

⚠️ Attention: On some firmware (MIUI, ColorOS) resetting the network can also remove passwords from Bluetooth-devices and VPN configurations. Before the procedure, back up important data.

Make sure Wi-Fi is turned on in the Quick Settings panel.

Check if power saving mode is activated (it may turn off Wi-Fi in the background)

Select the correct frequency band (2.4 GHz or 5 GHz)

Disable "Auto-connect to open networks" (on Android)
