m9 plus User Interface doesn't connect
I just got a deco M9 Plus and was promised tons of features and settings and so far none of them are available or "where they should be." My biggest problem right now is that the app doesn't show info on connected devices like which deco they are connected to and which band they are on (2.4 or 5) and some other information. Searching around told me that that information can be found on the User Interface through a browser (220.127.116.11) and no matter what I try, I can not get into the user interface. I have connected directly to the deco with an ethernet cord, I have used the above IP (which is the same as the "LAN IP" found in the deco app), I've used other IP's I found online in tp-link help pages, I've tried setting up the DDNS, I've tried random web address found in tp-link help (i can't remember exactly but something like tplinkwifi.net and something else) etc etc etc. If you need more specific information please ask, my brain hurts and I can't even remember all the things I've tried. Not to mention this may just not be available "until a firmware update" to which I ask, when will that come? Because I'm not really wanting to sit around and wait for something that has been promised for over a year and still isn't available when I can just buy a different mesh system and return this. Other than not being able to see ANY useful details of my connected devices, I will admit the system works very well and I would like to continue to use it and not buy something else with other problems.
Any help is appreciated. Thank you
PS My ISP is ATT uverse and my modem is the standard ATT modem/router I can find the name if you need it. but I have IP passthrough set up and that's about all i changed on there. Oh and turned off the WiFi on the ATT device because I assume that should be off if my Deco is my wifi now.
