Cannot Setup Administrator Password for New Archer C6 AC1200
Hello!
We purchased a new Archer C6 AC1200 wireless router. Connected all of the cables, power, etc. The device turns on and all the lights turn solid green. I can access site indicated on the Quick Start Guide, both tplinkwifi.net and 192.168.0.1. It prompts me to create an "administrator password". I have tried several different variants for a password - low/medium/high security ones, as well as the suggested "admin". No matter what I put in the box, when I click on the button "Let's Get Started", nothing happens. The page doesn't reload, it doesn't redirect anywhere, it just sits there and nothing happens.
I have tried it from a PC running Windows 10 with Chrome, Firefox, Internet Explorer and Microsoft Edge. I have tried it from a Macbook Pro from Chrome, Firefox and Safari. I also tried it on an Android smartphone from Chrome. All devices encounter the same issue - I can load the page to create a password, but it will not allow me to actually create one.
From my smartphone, I also tried to setup the device through the TP-LINK Tether App. There, slightly more information appeared in the form of an error message across the bottom of the screen "Unable to change or modify the username and password."
I have tried to do a hard reset of the router several times. It does not make any difference and I continually encounter the same issue.
There are no options for me to try any default username/passwords or bypass this screen. I have a new device that will not setup and will not work. Please help!
