Arcadyn - will not accept WiFi Password

Just curious as to if you save your passwords to the browser when you are given the option or not. I have the Nokia router and I encountered a bug where after backing out of a given configuration parameter in the web interface a prompt would pop to save the authentication. Well, after being locked out as you state I did some serious investigation. I tested half a dozen browsers on different OS, i.e. Windows 10, Apple MAC and iOS, and Linux. I discovered it was an interaction with the auto save AND the Nokia on the most recent code. I reported the behavior to T-Mobile and even reproduced the behavior 2x with two different browsers while on a call with a T-Mobile engineer. I found if I did NOT save the authentication info to the browser, any of them, I would not have the problem. I cannot say it is the same issue but worth checking. If you save your passwords to your browser check what the browser saved for the authentication to the admin account of the router. T-Mobile NEVER got back to me on the matter after the call so I doubt it is fixed. 

I saw a couple of different variations on what was saved. With the Nokia it would pop the save window and then if I said OK it would have the WRONG information saved. It was saving the WPA key as the password for the admin account in some instances. You have nothing to lose if you check the saved passwords for the access. I found I had to reset the router to default. Use the default admin password first and then go in and set my own personal admin password. After that using a browser sin the auto population of the authentication information from saved passwords was fine.

It might not be the same but it is worth checking out.
