Semi-Complicated Network

Sorry to be more specific. The router will have admin as the user but your browser will hold the saved incorrect information the web-gui sent to it. So if you were to back out of the 2.4Ghz config it may have no username and have the WPA Key as the password. If you backed saved changed information in the 5GHz config level then it would have the value of Max number of users, 128 as the user and the password would be the value of the WPA Key. Not like you would ever do this but that is what it does to you if you have auto save and auto fill for you authentication. Pick a browser you don't use as often and turn these off just so you can use it to manage the router. Then you just have to remember your login and do it manual each time. Not a big deal just only when it trips you up and you can't get in.
