I was haunted by poor performing Netgear Orbi tech for months and months, so finally decided to take the leap to TP-Link Deco technology. Looks great and performs even better - really pleased so far. However, it is all let down by this awful app. Sure, the install feature is simple and straightforward, but once installation is done with, the functionality of the app in access point mode is poor to say the least. It is slow and clunky, and visibility of key performance KPIs is non existent. I can’t see strength and speed of connection between decos, whether they are using the power line network, how strong the power line network is, which devices are attached to each access point, how strong their connection is, and much more Even though the latest release provided up speed and down speed indicators, non of them work. The Deco technology stack obviously supports different models working together very well, but why can’t the app cope with this. If only TP Link put the same amount of effort into their app development as their hardware and firmware development, this technology would be unbeatable. TP Link needs to pull their socks up big time with this app! Having said that, the performance of the hardware beats Netgear Orbi hands down, and the addition of powerline functionality is genius. Please TP Link - invest in the app and web interfaces ASAP.
