TP-Link - Deco X60 AX5400

I expect two Deco (X60 or X90) would be fine, if they can communicate between floor 0 and floor 2. How does the wifi signal work between your floors? With the router provided by your ISP, do you have some wifi signal on floor 1 and on floor 2? Results of speed test on floors 0, 1 & 2? What is the model of your ISP router and of the device you use for testing?

I have three TP-Link Deco X60 mesh WiFi routers in my 2100 SF ranch-style house. One is located centrally in the TV room connected to the ISP connection, one in our bedroom at one end of the house connected via ethernet through the crawlspace, and one in the garage on the other side of the house connected wirelessly to the central one. (The one in the garage provides an ethernet port for a Wyze camera base for 2 cameras.) Coverage is stellar on 2.4 and 5 GHz, and extends easily 100 feet or more outside the house in all directions. It supports WiFi cameras, tablets, phones, laptops, and Chromebooks, and they coexist with my wired home lab and office equipment. We have a 300x300 symmetric ISP connection, and everything is rock solid with zero dead spots.

Same. X60 and X90. I keep them in AP mode. They are great but I would love the ability to setup VLANs for extra security.

Okay thanks. That's how I understood it as well, just wanted to make sure my intuition was correct haha. I just bought a Deco x60 mesh system and plan on setting it up tonight. Hoping I can FINALLY play my Playstation Portal without the resolution tanking and the connection giving up after 5 minutes. I've been using a wifi extender (which I know are certainly not great) and I don't think the Portal enjoys that...

TPLink AX5400 or AXE5400, done. Those are around $100/$150 on Amaz right now, I did a quick check I am using AXE in 1800ish. The big thing on routers, be sure it has multiple CPUs in it, different class ARM stuff, but you want more than 1. /cheers

A vote here for the TP-Link AX5400. Works fantastically with the Quest 3 in all the games I've tried so far.

I own AX73 AX5400, C80 AC1900, C6 AC1200, and 3 others from TPlink. Replaced C6 through service centre. AX73 is the best no issue still now.

Return the decos and get another AX5400 and use easy mesh capabilities. What model do you actually have the AXE75 which has the 6ghz channel or do you have the AX75 or AX73 which both do speeds of 5400gbps but are just wifi 6 capable? Either way, all three of those models are easy mesh capable, which would probably be a lot better than having the Deco’s with the same Wi-Fi name and password even though it’s the same network topology it’s still different hardware and it’s probably gonna cause issues. That’s why I suggest the easy mesh route because that keeps the routers pretty much the same and eliminates the Deco hardware.

Hi everyone! Hopefully someone can help me on this topic since I'm not sure if the setup that I currently have for my parent's house is the best as it can be. For context, we live in a bit of a rural area, so we started using starlink to get the best possible connection for remote work. Now, I saw some reviews and recognized that the starlink router is pretty bad even though it does its job, that's the reason I ended up buying the AX5400 Router, which so far has given me 0 problems and has a lot of nice options. My problem/situation comes when I realize that if I want to cover most of my house and a bit beyond it (since we have a lot of open space which is the garden and a guests area) I needed to set up a mesh network. Along with the AX5400 router, I ended up buying a 3 pack of AX300 Deco wi-fi mesh in amazon and gave my best shot at setting up all of what I have, which is the following configuration: \- Starlink router was set to derivation mode as to use the router AX5400 as the actual router as to have better options with guest network, security, port forwarding etc. \- Connected to the AX5400 router via ethernet is one of the AX3000 decos, set as an access point for the network and using the same SSID as the router so that only 1 network appears when searching for wifi (besides the guest network, which was set up from the application for the AX5400 router). \- So far I've only setup 1 of the deco AX3000 in the first floor of my house, close to the guest area, while the other one is stored and ready to be setup somewhere else, this one is also set as an access point and has the same SSID. My doubts/concerns about this, is obviously the fact that since these 2 products don't share the same technology for setting up a mesh, there's nowhere I can see that says "hey, these are your mesh devices while these are the devices connected to your router", and when actually getting decently far away from the router, as in like walking through my garden, I don't know if I'm actually now getting connected to the deco mesh or it's just the AX5400 having great coverage. What I want to get advice on is whether what I'm doing is correct, if I fucked up something, and what could I do to improve my situation. TLDR; Have a AX5400 router and AX3000 deco mesh, don't know if I can use same SSID on decos set as access point or if I fucked up with some of my setup and should change how everything works. Thanks to anyone who might be able to help!

BE3600: (5 GHz speeds of 2882 Mbps and 2.4 GHz speeds of 688 Mbps) (𝟐.𝟎 𝑮𝑯𝒛 𝑸𝒖𝒂𝒅-𝑪𝒐𝒓𝒆 𝑷𝒓𝒐𝒄𝒆𝒔𝒔𝒐𝒓) \-Best for multiple stuff connected by cable because it has a better CPU. \-Best if few stuff connected by it to wifi 2.4, too many then it may have poor performance. why? 2.4 has 688 Mbps and wifi 7 depends on it as well, if you connect a lot of devices capable of 2.4 and 5ghz then you will have a lot of traffic competing with your main stuff, so you will have to manually configure the router to give your main stuff the preference... but even so... the wifi will be shared with IoT stuff... the wifi 7 performance will be hurt by it. AX5400: (6 GHz: 2402 Mbps;5 GHz: 2402 Mbps;2.4 GHz: 574 Mbps) (1.7 GHz Quad-Core CPU) \-Best for multiple devices connected to 2.4GHz and 5GHz while you use your main stuff on 6GHz \-If we are talking about the one that has 2x2.5Gbps WAN/LAN ports then it's a really good wired router even if a little bit worse than the BE3600 because while this has 1.7Ghz Quad-Core, the BE3600 has 𝟐.𝟎 𝑮𝑯𝒛 𝑸𝒖𝒂𝒅-𝑪𝒐𝒓𝒆 𝑷𝒓𝒐𝒄𝒆𝒔𝒔𝒐𝒓.... that is... if we are talking about local data transfers like a NAS... in short: many wifi devices? AX5400 and use 6ghz for your main stuff. few wifi devices and the heavy network traffic will be local stuff by cable? then BE3600

TP Linke Deco AXE5400 is like 200 bucks for set of 3. It is absolutely the best wifi i ever had. I got about 70 devices connected to it.

It's anecdotal, but I had a very terrible experience with a Unifi Dream Machine (before they were called Dream Router). The device I got was fine for about 3 months, and then it would randomly restart a couple times per day. I opened a ticket, and support was extremely slow to respond, and then they pushed an update which bricked the device, and when I asked about an RMA, they told me it had been too long. Now I'm just using a deco mesh 6 and it's rock solid

I can’t speak for the eero myself since it’s actually my brother who’s using it and I’ve got a Deco actually lol. The app kinda sucks but once it’s all setup I didn’t need to do anything else. Got the 3 pack from Costco and it’s been solid. Just needed to turn off fast roaming since it was cutting off uploads randomly. Guess the house is too small for 3 APs.

+1 for the Decos. (Decoes?) They've been pretty reliable over the year and a half-ish that I've had them. The app is a bit funky (esp for more advanced stuff), but as far as being a router, they seem great.

In similar situation: put in a TP Link Deco mesh. Omada is overkill.

TP Link Deco definitely requires an app and an account and although there is a web interface, it can't do much. Nice gear, but not acceptable under your policy. Netgear Orbi may have required me to install an app and get an account to get it setup (I didn't try to get around it.) But the web interface is full fat and I've never opened the app since installing.

No. Nest sucks. Deco or Eero if you want mesh.

TP-Link Deco work quite well, I've installed plenty of them. Even with wireless backhaul they cope well.

I used the deco mesh system in the end. Honestly I really like it, I have only had a few minor hiccups but the control I have is great and it was easy to set up. It also helped I got them $100 off

Even the mid range TP-Link mesh stuff goes well for your average home user with a couple of 4k TV's and a console plus phones and kids.

The wireless backhaul is nothing to sniff at on the better domestic mesh systems. I've got a higher end orbi system, and move an absolute boatload of data around, with more than 50 attached devices on the network, and it holds up very, very well. Your average home user will be well served by a Deco mesh.

I use a deco. I had disconnection problems when I was using the fast band and I saw someone recommended that Google home prioritize consistency over speed and that I should switch over to 2.4hz. I did that and my Google home has never had a disconnect since.

I’ve got a Deco. Didn’t want either Amazon or Google monitoring my WiFi.

TPlink Deco/some other mesh network system where you can just buy 2-3 of them and hardwire them all together. Should give you plenty of speed and coverage

With what looks like a large tree in between your house & guest house, I would think hard wiring that section would be best. We got a TP Link Deco mesh system back when we got our SL (Oct 2021) and have 4 mesh nodes (the first acts as the router) around our property, covering a few acres in good wifi. Originally, we had one at our house trying to wirelessly connect to another node at our guest house about 230' away (same as your 70m) but there were trees in the way, so once we laid in ground cable between those 2 nodes, we were able to then extend beyond to our shop & our gate.

If you want better configuration dont go Deco its locked down by the software app to run some services and tweak. Get one of the Onemesh or Easy mesh routers like the AXE5400. Will also add the deco's are fantastic access points but using them as a primary gateway not the smartest for the more experienced user that likes the standard routing options available to setup etc.

I have tp link Delco each has ethernet back haul works great.

\+1 for deco, I have 3 of them at home (one on each floor) and it works great!

Don’t bother with TP Link Deco either, ok router but not great Parental Controls.

I’m a big fan of the TP-Link Deco mesh stuff. The “will they be banned” stuff won’t affect firmware updates. You can always get them online; you just wouldn’t be able to buy them new again.

Asus AiMesh - Yea TP-Link Deco - Yes TP-Link Easy Mesh - Not sure

I bought a router and 3 extra points of the 2nd generation Nest Wifi. I had wifi issues all the time. A device would be connected to a point but have no internet. You can find forum posts of people complaining about this very same issue without any resolution from Google. I switched to Deco and have had 0 issues.

Deco works really well with extending range. Actually better than a range extender, as Mesh systems are designed from the ground up to work with each other in the system. I had a Ge800 tied to a be550 and a WiFi 7 range extender. Super good stuff right? But it's half ass "patched up" jerky jerky mesh was no match to a Deco. Deco was snappier, more reliable, and longer range.

Can confirm. Have Deco. Am miserable.

Tp link deco. Just a no fuss system. Plug in, download the app, set ssid and don't worry about it anymore for years. Mine has been stable and working for years. There are better systems out there for sure, but at the price point, it's good value

I am pretty happy with my Deco system. All these systems are typically discounted on prime day if you have surrendered your soul to Darth Bezos and if you can wait until then. I know the standard advice on this sub is to do hardwired APs. But without enterprise grade system with controller, devices (I am looking at you fruit-phone) tend to cling to APs. I think the mesh systems are somewhat better at making the devices hop since the stations can “talk” to each other. Read about 802.11 k/v/r if interested. Also, most mesh systems offer wired backhaul that will always make things better.

Don't they are an Archer You want a Deco Mesh System EasyMesh, OneMesh and Deco Mesh are not compatible with each other [https://www.tp-link.com/au/home-networking/deco/](https://www.tp-link.com/au/home-networking/deco/) Choose carefully and use 'Ethernet Backhaul' where you can to improve communication between Deco's I have 4 Deco's for a large apartment and I have strong signal everywhere. You may need more Deco's but start with 4 Also take note you do not need to buy Wi-Fi7 right now. Most of your devices can't use it fully, and, they may be more unstable using BE & MLO I would suggest Wi-Fi 6E tbh, cheaper and much more reliable (without upgrading every single piece of technology in your house)

TP link deco can’t fault it. Super easy, simple and user friendly app

Don't do this if you have a home network and semi-regular internet outages. I just discovered that Decos and TP-Link's gaming routers require a modem connection to route traffic for physically connected devices. This is probably no big deal for a lot of folks, but for those of us with a NAS, or PCs that require a physical connection, it's obnoxious. The Deco unit ports are WAN/LAN ports, and they default to WAN until a modem is detected (same for their gaming routers). During an internet outage, most modern modems go into a reboot cycle, and every time they do a full power cycle, the Deco no longer detects them, and flips all of its ports back to WAN. This results in your physically connected devices getting disconnected from your network every 15 minutes or so while the modem reboots, effectively rendering your home network useless.

the best solution will be having ethernet cable and attaching an ap at the end. or use existing coax with moca adapter. next best is to get a wifi mesh eg tplink deco get 2 or 3 and position them accordingly around the house.

best solution is to use ethernet cable, or coax with moca adapters and backhaul the AP. next best is wifi mesh.. eg tplink deco

I second that recommendation to get a mesh system. Also make sure the mesh system is capable of “WPA3 security”. I am using a TP-link Deco system, with 3 units. I have a 2 story 2100 sq ft home and this system covers all areas well.

I'm using TP Link Deco's. Wish I'd gone for UniFi (which I've just installed at work - my word it's good)

I second the Deco, good software with it too.

Ditto for TP-Link Deco. I forget which specific ones I have, but they’re easy to set up, and the app works well for device management.

I’ve had good luck with TP-Link Deco. I have a combined 5ghz and 2.4ghz main network, but I also have a separate IoT network that is 2.4ghz only. It’s worked well for a SwitchBot Hub Mini and a Lifx bulb. Another thing to consider is not using WiFi devices. Devices that use Thread or their own hubs are going to be more reliable. Zigbee devices are rock solid.

Another vote for Deco! I have a set of three that worked really well in a two story rental house and a two story townhome. They’re a little weaker now that we’re in a 2300sqft SFH, but I just may need to adjust placement or add another unit.

I was using decos until last week. Never been happy with them, random disconnects, rubbish app that won't let you change settings 9 times out of 10. Stuck with it since lockdown. Finally got fed up last week, ran some cat 5 cable from my router to an old router set up as an extender, more cat 5 from that to the next old router and now I have 4 daisy chained around the house and workshop. Rock solid wifi everywhere, and as a bonus, plenty of ethernet ports everywhere for pc's and tvs

TP Link Deco mesh system; set up a network just for guests and all our smart home stuff is on a private network.

I have this one too. If you can’t do a wired/coax backhaul between the nodes and have an older or brick house, I can’t recommend. The wireless bridge between access points is pretty horrible even like 20-30 ft from each other in my house. It works well once I added an outdoor Deco unit and ran coax extenders too, but it has way less 2.4 GHz range than our Verizon G3100 did.

Yeah, so... without going the "masquerade" route with a WAS-110, etc.. You'll have to put their ONT into pass through mode (the minute you do, they lose "visibility"), and I'd recommend tp-link, either Deco route, or if you want more control, Omada managed switch with AP's. I did this with a ER707 managed switch, but if you want single-system simplicity, Deco is hard to beat

Deco is good. It has prioritization of certain clients traffic.

Seriously, set it up at my parents too a couple of years ago. So easy to use and good price point and the security concerns are actually wildly overblown I find.

I’ll second the Deco system. I have the installed at my parents and in-laws houses. My mom actually installed it herself with no problem. If you’re not familiar with networking it’s great system. OP, if you want to use the Ethernet to connect them (I’d recommend if possible) you may need a small network switch as they usually only have two-ports on each node.

What I don't understand is where do I even find cheap access points with wifi 6? Technically it would be cheaper to get an Router + 2 APs but most I can't even find consumer APs for cheap where I live so I had to go with a TP-Link deco mesh system on a wired backhaul.

TP-Link Déco is cheap and simple to install. Other brands got more features, I don't need.

Lmao, I knew the minute I saw this that it was going to be someone with a tp-link deco. Same headaches here. I just manually restart them occasionally. One day I’ll switch to a different brand, just waiting on WiFi 7.

Another vote for deco, just works.

After 6 years with Google Nest Wifi, I just switched to TP Link Deco. It’s been flawless and just posted about how to reuse old points as speakers only. They are not top 5 on any list, maybe even top 10.

Yes I do - I have a very overkill setup at home which I won’t go into details haha. But generally, I think a TP Link Deco or similar mesh system would be fine - the important thing is to cable the mesh devices instead of using wireless mesh for max stability and speed. Well worth the hundred dollars or so paying a contractor to do the network cabling (and trunking) in your flat if you don’t already have the cables pre-laid.

I just got the same setup, it’s a big improvement in coverage over the Google mesh I had before. I bought the 3rd node separately in case I decided I didn’t need it, but it works better outdoors with it so I kept it. 

I actually went from Deco to eero because the deco wouldn’t play nice with my existing whole house tplink gigabit switch for the wired backhaul. Even though it was the same manufacturer. I tried forever, but finally I gave up and have now have 6 eero 6+s working great with better coverage at like half the cost. 3 packs were $199

Went from a Timecapsule to two Decos in a mesh and its been great.

I spent $150 on a TP link deco and it works well. No complaints. I’m not a high power user so you might not like their network management features as much.

Same. Plus all Decos are compatible with all other Decos, which makes upgrades easy.

Deco's are great and have everything you need. Make a separate guest network so they can't hamper things and a regular one for the IoT you have.

I have a 2 pack TP Link Deco mesh system and it works great for me.

Direct cable connection is always best option. Another option would be virgin in modem mode and then something like tp link deco with multiple ap’s. Are you able to drill a small hole through wall? Ethernet cables can be relatively cheap and with pass through connectors. You can run your own custom length through a hole just big enough for the cable then put rj45 connector on. Direct cable

Tp-Link all he way. Either Deco (if you want ease of installation) or Omada (if you want configurability). You can run the Omada Controller locally as a HA Add-On and also there is an Omada Integration giving you control over all your Omada gear, including control over PoE management on switches.

Deco are cheap but they moved a lot of stuff behind a paywall on the newer models. I just sent mine back and swapped it for an ASUS RT-AX58U V2 and been much happier with it. This router seems to cover the same as three mesh units did. Has a lot of features too. One I really like is IFTTT integration, so I can put the kids on a guest network and setup scheduling to turn off at bedtime. Something the decos could never do properly

I'd go mesh, if you have a cable already running to the back use that as wired back haul. I've been happy with my decos

Take the Spectrum modem, get a TP-Link Deco Mesh system (don't listen to the nonsense about them being banned in the US). My house is about 2500 sq ft, I have over 60 devices connected to it, and have ZERO issues.

I'm in the middle of upgrading my APs from 802.11ac to 802.11ax. It's a bit of a waste since ac speeds were fine. I have been experimenting with PCVR streaming lately though, and I also recently got upgraded to symmetric gigabit internet. I've purchased 3 TP-Link Deco units on eBay so far and they're boring in a good way.

Try TPlink deco routers they work tremendously

I use deco and it’s solid

I use deco setup just like Liam mentioned here, I bring the Ethernet cable from modem to the first deco node and then another Ethernet cable from first node in office goes to a switch in the second floor through in wall lan outlet and all the other rooms Ethernet cables come to the panel box in second room which are plugged into the above mentioned switch. Doing so all my three nodes are on wired backhaul. Never had latency issues.

It is a useful distinction, though, because consumer 'mesh' systems differ from conventional APs in two ways: 1. Mesh systems are intended to be a wireless only solution first where the end user won't typically have the infrastructure to hardwire them. It's great that a wired backhaul option is included, of course, but this isn't who they built the system for. 2. Their method of management and featureset are aimed at consumers rather than prosumers and SMB. Take two solutions from the same company: TP-Link Deco and TP-Link Omada. Deco is intended to be comprehensive and turnkey - you only need this one product and you're done. It has all of the features that consumers are likely to use, but it's also missing features that the most basic of access points should include, primarily multiple SSID and VLAN (802.1Q) support. For prosumers, this is immediately a disqualification, but most consumers don't have a clue what a VLAN is. I still recommend the Deco system depending on who the end user is. Compare this to Omada which is clearly a prosumer and SMB solution. It has all of the features one would expect, 802.1X, VLANs, multiple SSIDs, etc. It's also done from a single pane of glass, but via the Omada controller rather than directly. It's also usually more expensive. A feature often included in these higher end systems is a wireless backhaul which can be helpful in situations where getting infra in is challenging, but this is the opposite of the mesh in that wired infra is the default and to be expected. I don't like the marketing term mesh because it doesn't really reflect the value add of the solution. What's really common is someone will buy this for their tiny house thinking 3 radios will help their WiFi issues, when actually it's just made it so much worse, all without pushing that wired IS the best option rather than relying on wireless. What's great about these solutions is the robust wireless backhaul (not going to deny this) to use in situations where wired infra isn't present, a common reality in housing, and the user-friendly setup and administration of the solution.

Id check out the decos then unifi, unifi is pricer but nicer, my parents used decos forever without issue. If you just want some basic QOS/port forwarding you'll be good to go.

I have a Tp Link Deco mesh system and it works very well with my homekit setup.

Any router will work. That's one aspect of Specturm's setup that I really like. Depending on your space, you can either get a single router or a mesh system. I have two houses, have Orbi at one and Tp-link at the other. I had Asus for a while. I personally found the TP Link DECO setup easiest and the performance has been fantastic. Can get it cheap at Costco too.

Tp-link deco. It provided a great mesh network and you’ll have maxed out wifi everywhere in the house.

I have good luck using my deco home mesh, go through Walmart and you'll most of the time find it on sale for less than $100. I picked up my 2 pack for around $80

You're probably better off looking for a WiFi mesh solution that can daisy chain between each other. A cheap kit that'll do the job would be one of the TP link Deco mesh kits.

I use Deco work which is fairly lightweight traffic and eero at home with massive traffic. I haven't maxed out the eeros but haven't put the Decos to that same test. The eeros come back online and reconnect to everything much faster than the Decos. I like eero app way better.

Yeah, extenders don't work in big houses. For 3500 sq ft, get a mesh system like TP-Link Deco or ASUS ZenWiFi.Covers everything, no dead zones, no 5G or 2.4GHz.

Depends on construction materials but assuming wood and drywall your issue won’t be area per floor it’s getting the signal between floors. Wired data to Wi-Fi per floor is best but if that’s not available a tp-link deco mesh system on floors 1-3 ought to do you may need a 4th node on the fourth floor it’s just hard to say. It’s relatively inexpensive and easy to set up. TP Link is getting a lot of news right now so you’ll see some opinions on it. All I can tell you is that if you’re looking for ease of set up and solid operation at a good price its a good fit.

TP link deco is a really good one especially if you want a mesh setup.

I just for the TP link deco and highly recommend
