I used this plugin. It did reset the password to original. I know because now I can use the original password to login again via ftp or telnet. So this was successful. Thanks for this.
But still, with most current updated TNAP 6, when I try to stream via webif, or an app like Potplayer or VLC, then I'm presented with the login screen shown above in
Post #1 or similar. Entering the original login credentials still doesn't work. It just prompts again. What other login info is there for the box?
