These instructions are suitable for most modern routers, from budget ones TP-Link TL-WR840N to the flagship ASUS RT-AX88U And Keenetic UltraWe'll cover not only the standard web interface method, but also alternative methods for situations where access to settings is limited.

It is important to understand that Change your Wi-Fi password This differs from resetting your router to factory settings. In the former case, you simply update the security key, while in the latter case, you erase all settings, including the network name, encryption type, and associated devices. If your goal is to update the password without losing other settings, follow our step-by-step instructions. For clarity, we'll provide screenshots of popular brands' interfaces and point out common errors that cause users to lose network access.

Before you begin, please check:

• 🔌 The router is plugged into the network and the power indicator is green/blue
• 📶 Your device (laptop, smartphone) is connected to the router via cable or Wi-Fi
• 🔐 You have access to the current Wi-Fi password or button Reset on the body

1. Preparation: How to access your router settings

The first step is to log in administrator web interfaceTo do this you need to know Router IP address, login, and password for authorization. This information is usually indicated on a sticker on the bottom panel of the device (look at the fields Default IP, Username, Password). If there is no sticker or the data has been erased, use the universal combinations:

To open the Control Panel:

1. Connect to your router via cable (recommended) or Wi-Fi.
2. Open your browser (Chrome, Firefox, Edge) and enter the IP address in the address bar.
3. In the authorization window that appears, enter your login and password (see the table above).

⚠️ Attention: If the page does not open after entering the IP address, check:

• 🔗 Connect to the router (the LAN/Wi-Fi indicator should be on)
• 🔄 No VPN or proxy in your browser
• 🔍 The entered IP is correct (sometimes the address changes to 192.168.100.1)

2. Step-by-step instructions: how to change your Wi-Fi password

Once you've logged into the web interface, find the wireless network settings section. Its name varies depending on your router model, but it's usually:

• 📡 Wireless / Wi-Fi / Wireless network
• 🔒 Security / Protection / Security
• ⚙️ Settings / Settings (in some Keenetic)

Let's look at the process using popular brands as an example:

TP-Link (Archer, TL-WR)

Go to Basic → WirelessIn the field Wireless Password (or Password) Enter a new password. The recommended length is 8–20 characters using letters, numbers and special characters (!@#$%). Save the changes with the button. Save.

ASUS (RT-AX, RT-AC)

Open Wireless → General. In the block WPA Pre-Shared Key Enter a new password. Please pay attention to the field Authentication Method — it’s better to choose WPA2-Personal (or WPA3-Personal, if supported). Click Apply.

3. How to change your password if you forgot your old one

If you don't remember your current Wi-Fi or admin panel password, there are two solutions:

Method 1: Reset the router to factory settings

Press and hold the button Reset (usually it is recessed into the body and requires a paper clip) during 10-15 secondsuntil the indicators start flashing. After reset:

• 🔄 The router will reboot with factory settings.
• 📋 The network name (SSID) and password will become default (indicated on the sticker).
• ⚠️ All user settings (including linked devices, ports, parental controls) will be deleted.

Method 2: Connecting via cable (if you know the IP address)

If you remember the IP address of the router (for example, 192.168.1.1), but don't know the Wi-Fi password:

1. Connect the router and the computer network cable (usually included in the kit).
2. Open your browser and enter the IP address.
3. Log in with the factory login/password (see table in section 1).
4. Go to Wi-Fi settings and change the password.

⚠️ Attention: After resetting the router through Reset All devices (smartphones, smart speakers, cameras) will be disconnected from the network. They will need to be reconnected using a new password.

What to do if the Reset button does not work?

If the reset button does not respond when pressed, check:

1. Router power supply — the indicator should light steadily, without blinking.

2. Button integrity — sometimes the contacts become oxidized (try cleaning them carefully with alcohol).

3. Alternative method - some models (for example, ASUS RT-AX86U) support reset via utility Firmware Restoration (downloaded from the official website).

4. Optimal Wi-Fi security settings

Changing your password is only part of network security. To minimize the risk of hacking, check the following settings in your router:

• 🔐 Encryption type: Select WPA2-PSK (or WPA3-PSK, if supported). Deprecated WEP hacked in minutes!
• 📛 Network Name (SSID): Do not use personal information (eg. Ivanov_WiFi). A neutral name would be better, for example HomeNetwork_5G.
• 🔄 Opening hours: For maximum speed, select 802.11ac (or 802.11ax for Wi-Fi 6).
• 🚫 Guest network: If you don’t need it, disable it in the settings (Guest Network).
• 🔄 Firmware update: Check the section Firmware Upgrade and install the latest version of the software.

Additional security measures:

• 📵 Turn off WPS (vulnerable to brute force attacks).
• 🔗 Turn on MAC address filtering (if you need to restrict access to specific devices).
• 🔄 Change your Wi-Fi password once every 3–6 months.

5. Common mistakes and their solutions

Users encounter typical problems when changing their password. Let's look at the most common ones:

Error 1: Wi-Fi doesn't work after saving password

Possible causes and solutions:

• 🔄 The router did not reboot: Manually turn it off and on after 30 seconds.
• 📵 Incorrect character case: Password Password123 And password123 — different! Check it out! Caps Lock.
• 🔌 Firmware failure: Reset the router via Reset and configure it again.

Error 2: Unable to log in to the admin panel

What to do:

• 🔍 Check your router's IP address using the command line:

  ipconfig (Windows) or ifconfig (macOS/Linux)

  Look for the line Default Gateway - this is the required IP.

• 🔄 Try a different browser (for example, Firefox instead of Chrome).
• 📵 Disable VPN/proxy—they may block access to the local network.

Error 3: Devices won't connect to Wi-Fi after changing the password

Solutions:

• 🔄 Restart the device (smartphone, laptop) you are trying to connect to.
• 📵 Remove the network from the saved ones on your device and reconnect.
• 🔐 Check that your new password does not contain Cyrillic characters or spaces.

⚠️ Attention: If smart devices (lights, sockets, cameras) stop working after changing the password, they will need to be reconfigured. Some gadgets (for example, Xiaomi Mi Home) require re-binding to the new network.

6. How to create a strong Wi-Fi password

Weak passwords are the main reason home networks are hacked. Follow these rules:

• ❌ Do not use:
  • 🔢 Simple sequences: 12345678, qwerty, password.
  • 📅 Dates of birth, pet names, phone numbers.
  • 📛 The name of the router or network (e.g. TP-Link_123).
• ✅ Use:
  • 🔤 Combination of 12+ characters with uppercase and lowercase letters, numbers and symbols (!@#$%).
  • 🎲 Mental associations, for example: Cat!LovesFish777.
  • 🔐 Password managers (KeePass, 1Password) for generation and storage.

Examples of strong passwords:

• Winter! Evening_2026
• K0fe$Milk0m#5
• Taiga@Siberia99Ru

Check the strength of your password using specialized services (for example, Kaspersky Password Checker). If the service rates it as "weak" or "average," make the combination more complex.

7. Alternative ways to manage your router

If the web interface is unavailable or inconvenient, try these methods:

Mobile applications

Most manufacturers offer official apps for configuring the router from a smartphone:

• 📱 TP-Link Tether (For TP-Link)
