What are you talking about, whether it is a password for routing or a computer password, you can't tell.

If the router is reset and its wifi network still has a password; In this case, it may be due to the following reasons.

1.The router reset was unsuccessful.

If the router recovery is unsuccessful, then the configuration parameters of the router will not be deleted, so the wifi network still needs a password to connect.

Please note that when resetting the router, you need to press and hold the reset button for about 5-8 seconds while the router is powered on. For a more detailed introduction, please refer to the following article:

How do I factory reset my router?

2.The default wifi network itself has a password.

Some brands of wireless routers have a password for the default wifi network, which can be viewed on the sticker on the back of the router, as shown in the figure below.

When the router is reset, the wifi name and password will become the information displayed on the nameplate; At this time, when connecting to the default WiFi network, you need to enter the default WiFi password on the nameplate to connect.

3.The router or wifi network is confused.

In networks with multiple routers, it can be confusing for some novice users. For example, there are two routers A and B in the network, and the A router is restored to factory settings, but when it is connected to WiFi, it is connected to the WiFi network of Router B, so it prompts that a password is required.

Additional note: After the router is successfully reset, all configuration parameters will be deleted, and the router cannot access the Internet. At this time, you must set up the router again and complete the setup before you can surf the Internet.

After the router is reset, it is equivalent to the factory reset of the mobile phone, and all the information in it is deleted, so the first login after the reset needs to reset the login password, wifi password, and enter the broadband user name and password.

After the router is reset, all the setting information is gone, whether it is the broadband Internet account password or the wifi password, it needs to be set again.
