We'll cover how to change your password both on a computer and on a smartphone, as well as what to do if you've lost your old password.

⚠️ Note: The router admin panel interface may vary depending on the model and firmware version. If your screen looks different than the screenshots in this article, check the device model on the sticker on the back and compare it with official documentation of Dom.ru.

1. Preparing to change your password: what you need to know before entering settings

Before changing your password, make sure you have access to the router And administrator rightsWithout this, you won't be able to save the new settings. Here's what you'll need:

  • 🔌 Connecting to a router — via cable (recommended) or Wi-Fi. If you are connected via wireless but have forgotten your password, use network cable from the set.
  • 🖥️ Device with a browser — a computer, laptop, tablet, or smartphone. Any modern browser will do (Chrome, Edge, Safari).
  • 🔐 Administrator login and password - usually it is admin/admin or user/userIf they have changed, use the latest data.

If you've never changed your router's login information, try the standard combinations:

  • 🔹 Login: admin, password: admin
  • 🔹 Login: user, password: user
  • 🔹 Login: domru, password: domru (for some models)

Router IP address — is another key parameter. Usually it is 192.168.0.1 or 192.168.1.1, but at Dom.ru may differ. You can find it out:

  • 📋 On the sticker on the back of the router (look for the line Default Gateway or IP Address).
  • 🖱️ Via command line: press Win + R, enter cmd, then run the command 
    ipconfig
    and find the line Main gateway.

⚠️ Attention: If you are connected to the router via PPPoE (like many subscribers Dom.ru), changing your Wi-Fi password won't affect your internet connection settings. However, if you reset your router to factory settings, you'll have to re-enter your network access details—you can find them in your provider's account.

2. Login to the Dom.ru router control panel

Now let's get practical. Follow the instructions to open your router settings:

1. Open your browser and enter in the address bar Your router's IP address (For example, 192.168.0.1). Click Enter.

2. In the window that appears, enter administrator login and password (default or your current ones). If the data doesn't fit, try the options from the previous section.

3. After successful authorization, you will see main menu of the control panelDepending on the router model, the interface may look like this Dom.ru, Sagemcom or Sercomm.

  • 🔌 Make sure the cable is connected to the port LAN (usually yellow in color), not WAN.

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

Once you've logged into the control panel, find the wireless network settings section. For routers, Dom.ru It can be called differently:

Find the tab Wi-Fi or Wireless network|

Go to Security settings or Wireless Security|

Search for an item WPA/WPA2 or PSK password|

Check section Additionally, if you did not find the options you need-->

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

For routers Sagemcom F@st 5364:

  1. Go to Network → Wi-Fi → Security.
  2. In the field Network Key (PSK) Enter a new password.
  3. Select encryption type: WPA2-PSK (recommended) or WPA3-PSK (if supported).
  4. Click Apply or Save.

For routers Sercomm RV6699:

  1. Open Wireless → Security.
  2. Find the line Pre-Shared Key - this is the Wi-Fi password.
  3. Install Security Mode V WPA2-PSK.
  4. Save the changes by clicking the button Apply.

New password requirements:

  • 🔐 Length: from 8 to 63 characters (optimally 12+ characters).
  • 🅰️ Use it uppercase and lowercase letters, numbers and special characters (!@#$%).
  • 🚫 Avoid obvious combinations: dates of birth, names, words from the dictionary.
  • 📱 If your password is complex, save it in password manager (For example, 1Password or Bitwarden).

Important: After changing the password, all devices will be disconnected from Wi-Fi. You will need to re-enter the new password on each device.

4. Selecting encryption type: WPA2 vs. WPA3

When you change your password, you will be asked to choose network protection typeThe level of security and compatibility with devices depends on this:

Encryption type Security level Compatibility Recommendation
WPA3-PSK ⭐⭐⭐⭐⭐ Devices after 2019 It's best if all gadgets are new.
WPA2-PSK ⭐⭐⭐⭐ All devices (including old ones) Universal choice
WPA-PSK ⭐⭐ Obsolete devices Not recommended (vulnerable to hacking)
WEP ⭐ Very old gadgets Prohibited for use

If you have devices older than 5 years (eg. old smartphones running Android 6 or printers without updates), choose WPA2-PSKFor modern technology, you can safely put WPA3-PSK - it connects devices more reliably and faster.

What happens if I select WPA3 and my device doesn't support it?

If your gadget does not support WPA3, it simply won't connect to the network. In this case, go back to the router settings and select WPA2-PSK or mixed mode WPA2/WPA3 (if available).

⚠️ Note: Some routers Dom.ru by default they use WPA2 with an outdated protocol TKIPIf you see this option, be sure to change it to AES - This will increase security without losing compatibility.

5. What should I do if I can't change my password?

Sometimes errors occur when saving new settings. Let's look at common issues and their solutions:

Error 1: "The current password is incorrect."

  • 🔄 Check what you're entering administrator password (to log into the panel), not the Wi-Fi password.
  • 🔍 If you forgot your admin password, try the standard combinations (admin/admin, user/user).
  • 🔧 If nothing helps, you'll have to reset the router to factory settings (button Reset on the back panel).

Error 2: "Failed to save settings"

  • 🔌 Check it out router power supply — there may not be enough voltage (try a different power supply).
  • 📶 Make sure that no IP conflicts: in the command line, run 
    ping 192.168.0.1
    - If packets are lost, reboot the router.
  • 🌐 Try a different browser or clear your cache (Ctrl + Shift + Del).

Error 3: After changing the password, the Internet disappeared.

  • 🔄 Reboot your router (unplug it for 30 seconds).
  • 📡 Check if your settings have been reset PPPoE (if you have Dom.ru, they should be in the section Internet or WAN).
  • 📞 Call support Dom.ru by phone 8 800 333-70-00 — the problem may be on the provider’s side.
