Why You Need to Password Protect Your Wi-Fi: 5 Real Threats

Many users leave their networks open "temporarily" or use weak passwords, unaware of the risks. Here's what can happen if your Wi-Fi isn't secure:

• 🕵️ Traffic theftNeighbors or passersby can connect to your network, causing your internet speed to drop by 2-3 times. This is especially noticeable in the evening when everyone is watching 4K videos.
• 💻 Hacker attacksA vulnerable router can allow attackers to access your devices, steal bank card information, or install viruses.
• 📱 DNS spoofingA hacked router can redirect you to phishing sites even if you enter the correct address (for example, vk.com instead of vk.com).
• 🚨 Distribution of illegal contentIf someone uses your IP address to download a pirated movie or hack a website, you will be held responsible.
• 🔌 Router overloadEach additional device on the network increases the load on the router, leading to lag and spontaneous shutdowns.

According to statistics Kaspersky for 2026, 37% of home networks in Russia have weak passwords or are not protected at all. More than 60% of users don't even check the list of connected devices in the router's admin panel.If you haven't changed your default password yet, do so now.

Preparation: What you need to know before changing your password

Before you begin setting up, there are a few key points to check:

1. Find out your router model. It is usually indicated on a sticker on the back or bottom of the device (for example, TP-Link Archer C6 or Xiaomi Mi Router 4A).
2. Find your admin panel login details. This is an IP address (most often 192.168.0.1 or 192.168.1.1), login and password (usually admin/admin or admin/password).
3. Connect your phone to the routerYou can use Wi-Fi (if the password has not yet been changed) or a cable. Ethernet via adapter USB-C/Lightning → RJ-45.

If you can't find the data sticker, try the standard combinations for your model:

⚠️ AttentionIf you previously changed the admin panel password and forgot it, you'll need to reset the router to factory settings. To do this, press and hold the button Reset (usually recessed into the case) for 10-15 seconds. All settings, including the Wi-Fi password, will be reset!

Method 1: Change your password via the mobile app (the easiest)

Method 2: Change the password via the router's web interface from a smartphone

If your router doesn't have a mobile app or you prefer the classic method, you can access the admin panel using your phone's browser. The instructions are universal for all brands:

1. Connect your phone to your Wi-Fi router (or use a cable).

2. Open your browser (Chrome, Safari or Firefox) and enter the router's IP address in the address bar (for example, 192.168.1.1).

3. Enter your login and password for the admin panel (see table above).

4. Find the section Wireless (Wireless network), Wi-Fi Settings or Wi-Fi settings.

• ASUS: Wireless → General → WPA Encryption
• D-Link: Wi-Fi → Security Settings
• Keenetic: Home Network → Access Point → Security

What should I do if the web interface doesn't open?

If the router settings page doesn't load, check:

1. Is the IP address entered correctly (try http://192.168.0.1 And http://192.168.1.1).

2. Is the phone connected to the router via Wi-Fi or cable?

3. Is your browser blocking access (try opening in incognito mode or a different browser).

4. Are the network settings on your phone corrupted? (Try rebooting the router.)

If nothing helps, reset the router to factory settings (button Reset).

On some routers (for example, Zyxel Keenetic) The interface may look different. If you can't find the section you need, use the settings search (usually there's a search bar at the top of the screen).

Which encryption type should I choose: WPA2 or WPA3?

WPA3 — is a new standard (since 2018) that provides better security, especially on public networks. However, some older devices (e.g., Smart TV 2015 or printers) may not support WPA3In this case, choose WPA2/WPA3 Mixed (mixed mode) or just WPA2.

If all your gadgets were released after 2020, feel free to install WPA3-Personal.

Why don't some devices connect after changing the password?

This can happen for several reasons:

• The device does not support the selected encryption type (for example, WPA3). Try it. WPA2.
• The password contains characters that are not recognized (for example, Cyrillic or rare special characters). Use only Latin and standard characters (!@#$%).
• The old password is saved on your device. Delete the network in your Wi-Fi settings and reconnect.
