How to find wifi password? I have desktop PC connected with router by cable. Dont know ruters username and password. I like to connect my smartphone to wifi.
Log into the router and set the wifi password to whatever you like.
As said above it comes with the default log-on via network cable such as ( Example: User: admin Password: linksys ), but it depends on the brand & model of the router you have. Then you can set the SSID and WiFi Password to what ever you want.
Look for a sticker on the router itself. It may sometimes be printed on a sticker on the router itself. Then with your computer connected it and open your browser and type router ip addresses , now you can change your password.
