Before you begin, make sure your laptop is connected to the router. via cable (recommended) or via Wi-Fi. If you've forgotten your current Wi-Fi password but are connected via a wired connection, there won't be any problems. However, if you've completely lost access to the network, you'll need to resetting the router to factory settings.

1. How to access router settings using a laptop

The first step is to open the router's web interface. To do this:

• 🌐 Enter in the address bar of your browser Router IP address. Usually it is 192.168.0.1 or 192.168.1.1. For Apple AirPort use 10.0.1.1, and for some models Zyxel Keenetic — my.keenetic.net.
• 🔑 Enter your username and password to log in. By default, this is often admin/admin or admin/empty fieldFor exact information, see the sticker on the bottom of the router.
• ⚙️ After logging in, you'll be taken to the control panel. If the page doesn't open, check your connection to your router or try a different browser (we recommend Google Chrome or Mozilla Firefox).

Where can I find my router's IP address if the default ones aren't working?

1. Click Win + R, enter cmd and press Enter.
2. In the command line, run:

   ipconfig /all

3. Find the line Main gateway - this is the required IP.

⚠️ Attention: If you have previously changed your login settings (username/password) but have forgotten them, you will have to do Hard reset of the router. This will return the settings to factory defaults, including the default network name and password.

2. Find the Wi-Fi settings section

Router interfaces vary, but the wireless network settings section always contains the words Wireless, Wi-Fi or Wireless networkHere's where to look from popular manufacturers:

A critical detail: if your router has two networks (2.4 GHz and 5 GHz), you will have to change the password separately for each range. In most cases, setting up only 2.4 GHz is sufficient—this will ensure compatibility with all devices, including older smartphones and smart appliances.

Connect to the router via cable (recommended)

Find out the router's IP address (192.168.0.1 or 192.168.1.1)

Find your login/password (on the router sticker)

Open your browser in incognito mode (avoid saved cached data)-->

3. Select the encryption type and a new password

In the Wi-Fi settings section, find the following fields:

• 🔒 Security Mode / Security mode — choose WPA2-PSK (or WPA3-PSK, if supported). Never use WEP or Open network - This will make your network vulnerable to hacking in a few minutes.
• 📝 Password / Network key / PSK password — Enter a new password. Recommended length: 12–20 characters using letters (upper and lower case), numbers and special characters (!@#$%).
• 🔄 Version - If there is a choice, give preference WPA2 (the most balanced option in terms of security and compatibility).

Examples of strong passwords:

• Green$Tree7!Moon2026 - easy to remember, difficult to guess.
• C0ff33!nTh3_M0rn1ng - replacing letters with numbers increases durability.
• MyW1F1_N3t!Un1qu3 - Use personal associations, but avoid obvious data (dates of birth, pet names).

⚠️ Attention: If your router supports WPA3, but among the connected devices there are old ones (manufactured before 2018), select WPA2/WPA3-Personal (hybrid mode). Clean WPA3 may cause compatibility issues.

4. Saving changes and reconnecting devices

After entering the new password:

1. Click the button Save / Apply / Save (usually at the bottom or top of the page).
2. Wait for the router to reboot (this may take up to 2 minutes). The indicators on the router should flash.
3. Disconnect and reconnect all devices to Wi-Fi using the new password.

What should I do if I lose internet access after changing my password?

• 🔌 Check if the indicator light is on Internet / WAN On the router. If not, the problem is on the ISP's side.
• 📡 Make sure your laptop is connected to the correct network (sometimes routers create an additional guest network).
• 🔄 Reboot the router using the button Power or by removing the power supply for 30 seconds.

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

This may be due to:

1) Incorrect password entry (check letter case and special characters).

2) Incompatibility with WPA3 (try returning to WPA2).

3) MAC address restriction (if filtering is enabled in the router settings).

4) Device malfunction (restart your phone/tablet).

5. Additional security settings

In addition to changing your password, we recommend taking these steps to protect your network:

• 🔄 Change your login and password for logging into your router. (chapter System Tools / Administration). Use the same principles as for the Wi-Fi password.
• 📡 Disable WPS (tab Wi-Fi Protected Setup). This function is vulnerable to brute force attacks.
• 👤 Enable MAC address filtering (if you need to restrict access to specific devices).
• 🌐 Update your router firmware (chapter Firmware Upgrade). This closes the vulnerabilities.

How to check who is connected to your Wi-Fi?

Most routers have a section DHCP Clients, Connected Devices or Client listAll devices with their IP and MAC addresses are displayed there. If you see something unfamiliar, turn it off and change your password.

6. What to do if you forgot your router password

If you are unable to access your router settings due to loss of login information, please follow these steps: hard reset:

1. Find the button on the back of the router. Reset (usually recessed into the body).
2. Take a paper clip or a toothpick and press and hold the button 10-15 seconds.
3. The indicators on the router will flash - this is a signal that the router has been reset to factory settings.
4. Connect to the network with the default name (indicated on the sticker) and use the default password (usually admin).

Important: After the reset you will have to reconfigure:

• Internet connection (data from the provider: connection type, login/password).
• Wi-Fi name and password.
• Port forwarding (if used).

⚠️ Attention: On some routers (MikroTik, Ubiquiti) A reset only erases the settings, but preserves backup copies of the configurations. A complete wipe may require an additional procedure via WinBox or SSH.

7. How to disable other people's devices from your Wi-Fi

If you find unfamiliar devices in the list of connected devices, proceed as follows:

1. Remember or write them down MAC address (example: 00:1A:2B:3C:4D:5E).
2. Find the section in your router settings MAC Filtering / MAC address filtering.
3. Add other people's addresses to the blacklist (Deny) or allow only your own (Allow).
4. Save the settings and reboot the router.

Alternative method (fast, but temporary):

• Change your Wi-Fi password - all devices will be disconnected.
• Turn on the function Client Isolation (if any) so that devices do not see each other on the local network.

For advanced users: in routers based on OpenWRT or DD-WRT You can limit the bandwidth for specific devices or block them through iptables.

8. Common mistakes and their solutions

When changing a Wi-Fi password on a laptop, users encounter typical problems:

If the router does not respond to settings:

• Disconnect it from the power supply for 1 minute.
• Try a different Ethernet cable (if you are connecting via wire).
• Reset the settings and set up again.

⚠️ Attention: Router interfaces are subject to update. If your control panel looks different from the screenshots in the instructions, please refer to the manufacturer's official documentation or support.
