• Speedtest by Ookla (to measure download/upload speed).
• Ping & DNS (to check connection latency and stability).
• WiFi SweetSpots (to analyze the signal strength at different points in the room).

Optimal parameters for comfortable work:

If the speed is below the minimum:

• Restart your router and tablet.
• Check if other devices on the network are downloading updates.
• Change the Wi-Fi channel in the router settings (optimal: 1, 6, 11 for 2.4 GHz; 36, 40, 44, 48 for 5 GHz).
• Update your router firmware (in your personal account) Rostelecom or on the manufacturer's website).

FAQ: Frequently Asked Questions

Is it possible to connect a tablet to Wi-Fi without a password?

Yes, but only if the network is open (unencrypted). Such networks are found in some public places, but they are unsafe. If you're using a home router, a password is required—otherwise, strangers can connect to your network. As a last resort, you can temporarily disable the password in the router settings (section Wireless Security → Disabled), but it's risky.

My tablet connects to Wi-Fi, but the internet isn't working. What should I do?

The reasons may be different:

1. Problems on the provider's side (check the service status in your personal account) Rostelecom).
2. Incorrect IP/DNS settings (try manually entering DNS 8.8.8.8 And 8.8.4.4).
3. Block the device by MAC address (add the tablet to the allowed list in the router panel).
4. The tablet is malfunctioning (restart it or reset network settings).

If all else fails, connect another device (like a phone) to the router. If the internet works on it, the problem is with the tablet.

How to connect an old tablet (Android 5-7) to a modern Wi-Fi network?

Older devices may not support modern encryption standards (WPA3) or frequencies (5 GHz). Solutions:

• Change the router security type to WPA2-PSK (in settings Wireless Security).
