1. Preparation before connecting to Wi-Fi

Before attempting to connect to the internet via Wi-Fi, ensure all the conditions for a successful connection are met. Often, problems arise not from user error, but from improper configuration of the equipment or provider.

First, check that your router turned on and working stably. The indicators on the front panel should be green or blue (depending on the model) TP-Link, ASUS, Keenetic or MikroTik). A red or flashing orange light usually indicates a connection error with your ISP. In this case:

• 🔌 Reboot your router by unplugging it for 30 seconds.
• 📡 Make sure the cable from your ISP is firmly inserted into the port WAN (usually highlighted in blue).
• 📞 Check if your internet provider is currently undergoing maintenance (you can find this information in your personal account or by calling support).

Secondly, make sure the device you are trying to connect from supports Wi-Fi standard, which your router uses. For example, if the router only operates in the range 5 GHz, and your laptop 2015 release supports only 2.4 GHz, connection will be impossible. Most modern devices support both bands, but for stability it is better to use 5 GHz for nearby gadgets and 2.4 GHz — for devices in remote rooms.

2. How to connect to Wi-Fi on a smartphone (Android and iOS)

Connecting to Wi-Fi on mobile devices is extremely simple, but there are some nuances that affect connection speed and stability. Let's look at step-by-step instructions for Android 12+ And iOS 15+.
