The new laptop is finally here, but when you set it up, you notice that you no longer know the WiFi password. You - or at worst someone else - set it up for you years ago, and now it's, well, gone. But that's not a big deal: there are tons of ways to get your password back. And in the worst case, you can of course easily change it.
The simplest method: check the router's default password
Many modern routers are set up at the factory so that their WLAN runs in WPA2 mode. In order to make the setup as easy as possible for the user, a standard password has been set that you most likely used during the initial setup. The golden question is whether or not you changed the password afterwards. If you can't remember, you may have left your wireless router in standard mode - and you can just look up the password: It's printed on the bottom of the router! Simply connect to the WiFi and enter the WiFi network key printed on the bottom of the router - the connection may then already work.
Look in the old Windows PC
Alternatively, you can also look up your WiFi password on your old Windows PC, which usually still has WiFi access. In Windows 10 this is very easy: You first have to open the connection settings for the WLAN access and display the password there. We have described in detail how you can read out the WiFi password under Windows 10..
Read out WiFi password under macOS
If you have a Mac in the WiFi network, you can also read out the WiFi password here. The so-called keychain, a program that contains all the passwords stored in the Mac, helps with this. To read out the WiFi password under macOS, you can proceed as follows:
Read out the WiFi password on the router
If you are unsuccessful with the methods described above, there is another way to get the WiFi password: You have to read it out directly from the router. All you need is an end device that is still connected to the router via WiFi or an Ethernet cable. An Internet browser must be running on this device. You can even do that with the smart TV! The procedure is very simple on the widespread FritzBox, but other routers are structured similarly, which is why reading out the WLAN password should not be a problem here either:
The rough method: reset router
If all measures do not work, for example because you have messed up the router access password, there is one last option: you have to completely reset the router. This allows you to set up the device again and set a new access and WLAN password or ensure that the standard password is valid again. Most routers have a reset button for this purpose, the operation of which is best looked up in the manual. Modern FritzBox routers, however, require a different approach. It is important to note that if you reset the router, you will have to set up everything again, which is not entirely trivial. If you are not confident enough to do this, it is advisable to consult someone who is familiar with it. We explain here how to reset your FritzBox to factory settings.
Read out WiFi password under iOS and Android? Unfortunately, no.
In contrast to Windows and macOS, the mobile systems iOS and Android do not have the ability to read out WiFi passwords. Although this is for security, it is extremely annoying if you lose your WiFi password. However, there are other methods of finding out a WLAN password via end devices: If you have a Smart TV , it is possible that the password was saved here in plain text. Alternatively, you can also check the network settings of other devices to see whether the password is displayed here. Unfortunately, the sheer variety of devices and operating systems means that we cannot provide any specific information here, but what is important: If a password can be read out, you can find it in the network settings of the respective device..
