This isn't an uncommon story with former Ubiquiti users. The prices keep going up and functionality seems to be more and more mediocre relative to other offerings, particularly on the routing side which has always been under powered and taken an age to implement features that should have worked at launch.
I sat down at the start of last year with major building works planned, all my backhaul links would be ripped out and it was time to upgrade three floors of AP’s and potentially core/floor switches. Almost anything was on the table as it would be a rounding error in the overall bill and I started looking at upgrading the AP’s to 6e, but availability was limited, prices weren’t great and my builder ended up giving me less than 24hrs notice on starting work, so I grabbed a pair of x20’s. I didn't have high expectations, they were surprisingly not awful (builder's on the other hand
), and managed a pretty steady 800mbit+ via iperf wired clients, node to node between floors and better coverage than the AC-Lite’s. After that, I found it hard to justify spending Ubiquiti money for 6e AP’s, so grabbed an extra pair of x50’s and haven't looked back.
I can’t comment on the routing side of Deco, clearly it’s consumer orientated, but having spent some time playing with the Aginet side of TPLink (basically Deco for ISP’s), its certainly better than most ISP issued stuff. My only issue with Aginet is it wont cross manage Deco or Tapo stuff as the Deco app will.
