  • 🔐 Length: minimum 12 characters (optimally 15-20). The longer it is, the more difficult it is to select.
  • 🅿️ Symbols: Use upper and lower case letters, numbers and special characters (!, @, #).
  • 🚫 Exclude: dates of birth, names, dictionary words, repeating sequences (aaaa, 1111).
  • 🔄 Update password once every 3-6 months (or immediately if you suspect a leak).

Examples of strong passwords:

What to do if you forgot your router password

If you don't remember your Wi-Fi password or admin panel login information, you'll need to reset your router to factory settings. This will erase all your settings, including the network name (SSID) and password, but will allow you to set everything up again.

Reset instructions:

  1. Find the small 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 secondsuntil the indicators start flashing.
  3. Release the button and wait for the reboot (1-2 minutes).
  4. Connect to the router's network - its name will be standard (for example, TP-Link_XXXX).
  5. Login to the control panel via 192.168.0.1 with login/password admin/admin.

After resetting, configure the router again:

  • 🌐 Come up with a new network name (SSID) - do not use personal information.
  • 🔒 Set a complex password (see recommendations above).
  • 🔄 Update your router firmware (section System toolsFirmware update).
⚠️ Note: On some models TP-Link Deco the reset is performed through the application Deco. Press and hold the button Reset for 5 seconds until the indicator turns yellow, then follow the instructions in the app.

Common mistakes and how to avoid them

When changing a password, users often encounter common problems. Here's how to solve them:

  • 🔌 "Settings are not saved"Check if your antivirus or VPN is blocking your router connection. Disable them during setup.
  • 📵 "The phone won't connect after changing the password.": Delete the network from your phone's saved connections and reconnect. On Android: Settings → Wi-Fi → [your network] → Forget.
  • 🔄 "The router keeps rebooting.": This may be a sign of a firmware failure. Try updating the software through the section System tools.
  • 🌐 "The web interface won't open.": Make sure there are no typos in your browser's address bar (e.g. 192.168.o.1 instead of 192.168.0.1).

If after changing the password the internet connection is lost, but the router still distributes the network (devices connect, but there is no internet access), check:

  1. Settings WAN (chapter Net or Internet). It's possible that your connection settings to your provider have become corrupted.

  3. Connection status in the web interface. If there is an error (for example, PPPoE authentication failed) - re-save your login/password from your provider.

Additional security settings

Changing your password is just the first step to securing your network. We also recommend:

  • 🔄 Update firmware: Outdated software contains vulnerabilities. Check the latest version in the section System Tools → Firmware Update.
  • 🛡️ Disable WPSThis feature makes connecting devices easier, but it's easy to hack. Find the option in Wireless Mode → WPS Settings and deactivate.
  • 📡 Hide SSID: Your network will not be visible to strangers. It is included in Wireless → Wireless Settings → Hide SSID.
  • 👤 Change administrator login/password: By default this is admin/admin — too predictable. Do it in the section System Tools → Password.

For models TP-Link Deco Additional features available:

  • 🔐 Guest network: Create a separate network for guests with limited access to local devices.
  • 👶 Parental control: Limit internet access time for specific devices.
  • 🛡️ Defense against attacks: Enable the built-in firewall (Security → SPI Firewall).

If your router supports WPA3 (new encryption standard), select it instead WPA2-PSK in the security settings. This will increase protection against hacking.

Is it possible to change the Wi-Fi password without access to the router (for example, if I'm not at home)?

No. To change the password, you need to physically interact with the router: either through its web interface/application on the local network, or by pressing the reset button. ResetThis can't be done remotely—it would be a serious security vulnerability.

I changed my password, but some devices won't connect. What should I do?

Remove this network from the saved networks on the affected device and reconnect. On Windows: Settings → Network & Internet → Wi-Fi → Manage known networksOn Android/iOS: Find the network in the Wi-Fi list, tap "Forget," and re-enter the password.

How do I know who is connected to my Wi-Fi?

In the router's web interface, go to Wireless Mode → Wireless Mode Statistics (or Wireless → Wireless Statistics). There will be a list of connected devices with their MAC addresses. In the application Tether This information is displayed in the section Connected devices.

Is it possible to set a password on the router itself so that no one can access the settings?

Yes, this is done in the section System Tools → Password (or System Tools → Password). Create a strong administrator password (different from your Wi-Fi password) and store it in a safe place. Without it, you won't be able to access your router settings.

What should I do if my internet speed drops after changing my password?

This is unlikely to be related to a password change. Check:

  • Has the Wi-Fi channel changed (try selecting it manually? 1, 6 or 11 for 2.4 GHz).
  • Have any new devices connected that consume traffic?
  • Have your provider settings been reset (section WAN).

Reboot your router and test the speed on speedtest.net.
