@Javito i have the same problem. same gateway. last fw installed but no users tab or statistics. i tried the refresh trick but is not working on my device. dpi enabled. i can see app analytics but no users analytics. 

i really hope that TP-LINK will work on this issue. Asus EBG19P can do that on 512 MB RAM!!!! also various things like wake on lan clients. ER7212PCv2 is a more powerful device but is missing a lot of features. i was thinking also about the software controller but  that was the point on getting a 3in1 device. controller, router, poe switch.

some controller and switch features are missing for this device. i`m thinking if i should return it and go with another brand. 

  @DonLeonhard I wouldn't go with another brand tbh, iv beennworking with tplink enterprise devices for the past 10 hrs and iv been really happy, but now that I know I'm not alone with this device, I'll definitely return it and get a er7206, that gateway is awesome, been using it on one or the companies I handle for the past 6 hrs without any issues, I'll have to get a poe switch cause there's no other gateway that has poe included :-( 

It's really a bummer that u can't use the router with an external controller or else i would definitely keep it

  @Javito 

Only the OC400 hardware controller and Software controller (i think) can show per-user DPI data

  @GRL wasn't aware of the oc400, but i have 2 software controllers and they both work just fine, so im def returning this gateway tomorrow, i don't get why do they have the option there if its not going to work
