TP-Link Deco XE75 AXE5400 with three “nest” units. I have the main and the upstairs bedroom unit hooked together with a cat5 cable… the bedroom one has a cat cable out to an Xbox and my cctv and it works flawlessly. The third unit is WiFi connected and reaches our Birdbuddy in the backyard. According to the instructions if I wired a cat cable to the kitchen unit it would increase the speed back but so far I see no reason. Since the system is a nest I no longer have to disconnect from my former router then reconnect to the extender for my backyard and garage. I added several Tapo cameras and the connections are perfect. I am not a techies (I would say 7 of 10) so the inability to dive into the programming is a non-starter for me. I set it up like the manufacturer recommended and saw no issues. FYI… when I look at all the geek responses below that is exactly the opposite of me and my situation. I found this system easy (enough) to set up and I had no need to dive into acronym hell…..
I just bought the tp link deco xe75 pro on amazon, they have a 20% back of using prime Visa card. Otherwise the Xe75 non pro is identical minus no 2.5G port.
I use the same routers for 1 gig. Just get 3 of the xe75 non pros
Deco xe75 is nice if you have two or three
I’m very happy with Tp link deco 6E
I have the Deco XE75 and do not have them wired for backhaul. Wifi speeds range from about 350 to 850 on a 1g fiber line. Ethernet gets me 980ish which is about max with 1g Ethernet port on router and 1g switches. That is usually ample speed for anything with running wires.
I have three nodes to cover 3200sqft over two floors. I rarely use 6ghz as my speeds are good and the 6ghz really need line of sight to be of any value. Having said that, I primarily run "smart" devices off the WiFi guest network and cell phones and laptops off the primary WiFi. NAS, desktop computer, etc. are run via Ethernet through a switch.
I've had an excellent experience with my Deco mesh system. And I have several TP-Link switches which have run flawlessly for going on 6 years now.
I have 3200 sqft with two stories and use a Deco 75xe - excellent coverage throughout. Many people hate mesh and will push for APs. While I do agree you will have better speed, often times the point of mesh is to avoid running wires - like if you are renting. I have three units running. I do not have an attic space, but my house is wide - so I needed three to get end to end coverage plus the 2nd floor. I know nothing about Nighthawk mesh - but don't want you to be scared off by the mesh haters.
I agree with promo pawn - a 3 pk mesh will cover a large house. I'm using TP Link DECO without wired back haul and pull 700-800 down wireless on an 800 download service.
I went with Deco - works great. Two story house 3,200 sqft, no dead spots. Guest network segmented from main. Each unit has a backhaul port as well as two ports that functionally work as a switch if you have something that requires an Ethernet cable.
I’m very much just wanting chiaki and GFN to run without problems and have spent way too much time trying to get my deco XE75 decos to work. They are great for everything besides my steam deck. Looking for help!
I’ve been testing a BE65 over the last week. Have packed it up and sending it back. For my setup and devices, too many devices dropping off the WiFi network regularly. Had exactly the same with XE75. Have reverted to my trusty old Eero 6+, no drops at all
I used TP-Link XE75’s and wasn’t impressed. For HomeKit, it was OK(ish), but general performance was hit and miss. When I changed my ISP, they provided an Eero. I’d always been against the idea of having Amazon owned stuff in my house, but thought I’d try it and see what it was like. I have to say that’s it been great. Sold the XE75’s and stuck with the Eero. Rock solid performance, no frills, easy to setup and is very reliable. Only time it restarts is during a software update. We forget it’s there, strong and fast WiFi is always available. Got 30-40 devices connected to it, new devices connect with ease and it never skips a beat. Would love some Unifi stuff, but while the Eero performs as it does, I can’t justify the expense of investing in new gear.
I went from Deco’s that had devices drop off regularly to Eeros supplied by my ISP. It’s like night and day. Eeros are rock solid and work perfectly with my Apple Home setup. I intended to go down the Unifi route until I realised just how reliable and well performing the Eero’s were. They are ‘plug and play’ and you can’t change much, but are pretty much ‘set up and forget’. Just my own experience and it may be different for someone else.
