Important: If you rent a router from a provider (for example, Rostelecom or Beeline), some settings may be locked. In this case, you'll need to contact support—but first, check whether your model is a "white" version, where restrictions can be removed by resetting to factory settings.

1. Preparation: What you need to know before changing your password

Before you go into settings, make sure that:

• 🔌 Router ASUS connected to the power supply and turned on (the power indicator is green or blue).
• 💻 Do you have a device (PC, laptop, smartphone) that already connected to this router's network via cable or Wi-Fi.
• 📝 You know the current network password (if you're connecting via Wi-Fi) or your admin panel login information.
• 🔄 The red error indicators on the router are not lit (if they are, first resolve the connection issue).

By default, most routers ASUS Use the following login details to access the admin panel:

If you have previously changed your login/password for entering the settings and have forgotten them, you will have to do it again hard reset router.

After the reset, all settings, including the Wi-Fi password, will return to factory defaults, but customized settings (such as port forwarding) will need to be reconfigured.

⚠️ Warning: If your router was configured by your ISP (for example, for IPTV or MAC address binding), resetting it may disrupt your internet connection. In this case, before resetting, check with your ISP support to determine which settings you'll need to restore manually.

2. Login to the ASUS router web interface

The most secure way to change your Wi-Fi password is through a computer browser. Mobile app ASUS Router Sometimes it doesn't display all the options, especially on older models. Follow these instructions:

1. Connect your device to the router via cable (recommended) or Wi-Fi.
2. Open any browser (Chrome, Firefox, Edge) and enter in the address bar 192.168.1.1 or router.asus.com. Click Enter.
3. In the window that appears, enter your login and password (default - admin/admin). If the data does not match, check the sticker on the bottom of the router.
4. After successful login, you will see the main page of the web interface. On new models (RT-AX88U, TUF-AX3000) it will have a dark background and tiles, on the old ones (RT-N12) - with a blue menu on the left.

If the page does not open:

• 🔄 Check that you are connected to the correct network (not to a neighbor with the same SSID).
• 🛠️ Disable VPN or proxy in your browser.
• 🔧 Try a different browser or clear your cache (Ctrl+Shift+Del).
• 📡 Make sure your router's IP address hasn't changed. To do this, use the command line (Win+R → cmd) enter ipconfig and find the line "Default gateway" - this is the current IP.

3. Step-by-step instructions: changing your Wi-Fi password

After entering the interface, proceed to the main menu. On new models ASUS (firmware Asuswrt-Merlin or standard) the path is:

1. In the side menu, select Wireless network (Wireless (in the English version).
2. Go to the tab General (General). Here you will see fields for network settings. 2.4 GHz And 5 GHz (if the router is dual-band).
3. Find the field WPA Pre-Shared Key (WPA Pre-Shared Key) — this is your current Wi-Fi password. Erase it and enter a new one.
4. In the drop-down menu Authentication method select WPA2-Personal (recommended) or WPA3-Personal (if all your devices support this standard).
5. In the field WPA encryption install AES (Not TKIP!).
6. Click Apply (Apply) at the bottom of the page.

For older models (RT-N10, RT-G32) the interface may differ:

Settings → Wireless → Authentication Method: WPA2-PSK → WPA Key: [enter password] → Save

The password is at least 8 characters long|Uses uppercase and lowercase letters and numbers|Encryption method is WPA2-Personal or WPA3-Personal|Encryption is AES (not TKIP)|The password is written down on paper or in a password manager-->

After applying the changes, the router will reboot (this will take 1-2 minutes). All devices will be disconnected from Wi-Fi, and you will have to reconnect with the new password. If the internet still doesn't work after the reboot, check to see if the settings have been reset. WAN (especially if you have PPPoE or static IP).

⚠️ Warning: If you use guest network on the router ASUS, its password is changed separately in the section Guest network (Guest Network). Changing the master password does not affect guest access.

4. Optimal security settings for Wi-Fi

Simply changing your password isn't enough—you need to set up proper security. Here's what network security experts recommend:

• 🔐 Encryption type: always choose WPA2-Personal (or WPA3-Personal, if all devices support it). Protocol WEP hacked in minutes, and WPA (without number) is obsolete.
• 🔤 Password length: minimum 12 characters, 16+ is better. Use a mix of uppercase letters, numbers, and special characters (!@#$%). Example of a strong password: K9#pL2$vQ1!mN5*.
• 📡 Hiding the SSID: disable the option Hide SSID (Hide SSID). This does not improve security, but it does make connecting new devices more difficult.
• 🔄 Firmware update: check the software update in the section Administration → Firmware UpdateOutdated versions contain vulnerabilities.

For advanced users: If your router supports WPA3, but some devices (like older printers or smart light bulbs) can't connect, turn on compatibility mode (WPA2/WPA3-Personal). This will allow both standards to be used simultaneously.

How to check which Wi-Fi standard your device supports?

On Windows: open command prompt and type netsh wlan show driversFind the "Radio Types" line—it will list the supported standards (for example, 802.11ac means Wi-Fi 5).

On AndroidGo to Wi-Fi settings, tap your network, and check your connection speed. 866 Mbps and above are Wi-Fi 5 (802.11ac) or 6 (802.11ax), which support WPA3.

5. Common mistakes and their solutions

Even after changing your password correctly, problems may still arise. Let's look at common issues and how to fix them:

🔴 Devices won't connect to Wi-Fi after changing the password

• 🔄 Reboot your router (button Power or via the web interface).
• 🔧 On your device, remove the network from your saved connections and reconnect.
• 🛠️ If this doesn't help, check if your Wi-Fi channel settings are correct (in the section Wireless Network → Professional Select a channel manually, such as 6 or 11 for 2.4 GHz).

🔴 After changing my password, my internet connection disappeared.

This means that the settings are lost. WAN (connection to the provider). Go to Internet (WAN) and check:

• 🔌 Connection type (PPPoE, Dynamic IP, Static IP).
• 📝 Login and password from your provider (if PPPoE).
• 🔢 VLAN settings (if used).

If you are unsure, call your provider's support team and clarify the parameters.

🔴 Changes to settings are not saved

Possible reasons:

• 🔋 The router is overheating or not receiving enough power (try a different power supply).

• 👤 Set up MAC access control: in the section Wireless Network → MAC Filter Whitelist only your devices. Cons: You'll have to manually add each new device.
• 🕒 Enable Wi-Fi scheduling: If the network is not used at night, turn it off Wireless Network → ScheduleThis will save electricity and reduce the risk of night attacks.
• 🔍 Check connected devices: in the section Network map (Network Map) Check for any unknown devices. Unknown IP addresses are a sign of hacking.

For owners of routers with firmware Asuswrt-Merlin (popular alternative firmware) additional options available:

• 🛡️ Enabling the VPN server directly on the router (section VPN).
• 📊 Detailed traffic statistics by devices.
• 🔗 Configuring individual VLANs for the guest network.

⚠️ Attention: If you have enabled MAC address filtering, but forgot to add a new device, it won't be able to connect to the network even with the correct password. Always keep a backup device with an authorized MAC address on hand in case of blocking.
