Recommendations for creating a strong password
The security of your network depends on the strength of your key. Simple combinations like 12345678 or password They are cracked instantly. The password must be unique and difficult to brute-force.
Use a combination of uppercase and lowercase letters, numbers, and special characters. Passwords should be at least 12 characters long for maximum security, although the standard requires a minimum of 8. Avoid using personal information, such as birthdates, pet names, or phone numbers.
A good example of a strong password is a phrase where the first letters of words are replaced with numbers or symbols. For example, the phrase "I like to walk in the park in 2026" could become YlgvPv2026g!This type of password is easy to remember by association, but extremely difficult to crack.
- 🔒 Use at least 12 characters.
- 🔢 Combine uppercase and lowercase letters, numbers, and punctuation marks.
- 🚫 Avoid using dictionary words and key sequences (qwerty).
- 📝 Write down the new password in a notepad until you remember it.
Changing your password regularly, at least every six months, significantly reduces the risk of unauthorized access, even if someone has previously gained access to your network.
Common problems and their solutions
Sometimes users encounter a situation where their devices can't connect after changing their password. This is most often due to the old profile data remaining on the device. There's only one solution: find your network in the list of available Wi-Fi networks, select "Forget Network," and reconnect using the new key.
Another common problem is losing access to the web interface. If you've changed the password for your router settings (not to be confused with your Wi-Fi password) and forgotten it, only a hard reset will help. Hold down the button Reset on the switched on router for 10-15 seconds until the indicators blink.
If your router isn't providing internet after a reset, your provider's settings (PPPoE, L2TP, or dynamic IP) may be incorrect. In this case, you'll need to re-enter the information your provider provided when signing your contract.
What should I do if I forgot my Wi-Fi password but have a connected computer?
If you have a Windows computer that's already connected to Wi-Fi (or was previously connected), you can view the saved password. Open the Command Prompt (cmd) and enter the following command:
netsh wlan show profile name="Network_Name" key=clearIs it possible to recover a deleted Wi-Fi password?
The router itself doesn't store a history of previous passwords. If you've changed your password and forgotten the new one, and none of your devices remember the old one, the only solution is to reset the router to factory settings using the Reset button. After that, you'll have to set up your internet connection again.
Does changing your password affect your internet speed?
No, changing your password doesn't affect your speed. However, if you had a lot of "neighboring" devices connecting to your network and consuming bandwidth, changing your password and disconnecting these devices may significantly improve your internet speed.
Should I change my password if my neighbors know it?
Yes, absolutely. Even if your neighbors are simply using the internet for free, they're hogging bandwidth, reducing your speed. Furthermore, your network could theoretically be used for activities for which you, as the connection owner, would be legally responsible.
How often should I change my router password?
It's recommended to change your Wi-Fi password at least every 6-12 months. If you notice suspicious activity (flashing lights when no one is using the internet, or unknown devices appearing in the client list), you should change your password immediately.
