A6X login and password

updated a brand new A6X and did the unlock it than asked to set up a password, which I did. after reboot it is now asking for a user name and a password. It never asked for a user name at setup.

The username is root. I also struggled with this for a few minutes before finding a post by @DustinS that mentioned this.

Can you comment on the performance? is it very different than A5? what distances haveyou put customers and what througput? Iam not sure if buy it or not. Tks
