How to change a Wi-Fi password if you forgot it?
Answer
You have not even written what kind of router you have, what devices are connected. Therefore, I will not advise you anything specific.
You don’t have to change the password. You can try to remember it. Look on your PC, or in the router settings.
If you have forgotten the password to your Wi-Fi network, you can look it up on your computer. If you have a computer that is currently connected to your Wi-Fi network, or used to be. If you have Windows 10, check out this article. There I showed you in detail how to view your Wi-Fi password in the router settings.
If you can’t view your Wi-Fi password on your computer, you can go to your router settings and view the password there, or change it. I showed you how to do this on the example of TP-Link router in this article: /tp-link/how-to-find-out-the-password-on-the-tp-link-router-we-will-find-out-the-password-from-wi-fi-and-settings/.
