"Actually better than a range extender, as Mesh systems are designed from the ground up to work with each other in the system. ... But it's half ass "patched up" jerky jerky mesh was no match to a Deco. Deco was snappier, more reliable, and longer range."
"Became FANTASTIC once I strung some ethernet cables among four of them including the one serving as a router in strategic locations (our house is rather large and some walls contain metal lathe). ... We now always have excellent connectivity and fast roaming."
"I have tp-links deco mesh system and it’s rock solid."

"My mom actually installed it herself with no problem. ... If you’re not familiar with networking it’s great system."
"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. ... At least this way I can see what is and is not working and troubleshooting is easy. I also have a variety of controls to see who is connecting to what and I can block things easier"
"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."

"i noticed a BIG improvement once i conected all my decos via ethernet. ... it was a game changer, i use smart products from different brands and now i don't have any issues with disconections!! ... Some meross plugs disconected all the time before wiring my decos, now they work flawless!"
"the important thing is to cable the mesh devices instead of using wireless mesh for max stability and speed."

"TP Link Deco definitely requires an app and an account ... although there is a web interface, it can't do much."
"Can confirm. Have Deco. Am miserable."

"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."
"I had Deco. Spend hours trying to extend WiFi range with another node. Fail."

"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."
"I got one that it's WAN port maxes out at 100 Mbps :\"

AustinGroovy 1.0I've used the S4 AC1900 trio (older but worked well), along with the X55 trio. Still Wifi 6 but decent coverage. The one failure was the Eero Mesh 6, stopped working but got a replacement set from Amazon and shipped the old set back. No problems since then.
flair11a 1.0I ditched the Spectrum router and connected directly to my Mesh router. Works awesome. https://a.co/d/eQkmmO0
NoodlesSpicyHot 0.0Best I've owned. No hesitation. I use their DECA mesh with success. TP-Link is a big company. If they do get banned, there will be a pivot towards something the MAGATs will find less offensive. For folks asking what the ban is about. Netgear and other US networking gear manufacturers have been lobbying hard with the GOP, sowing Chinese fears about TP-Link. Not because TP Link gear originated in China (Netgear, Cisco, Juniper, Aruba, and others also have gear made in China), but because TP Link gear is good and much lower in cost, which is eating into their profits. Sales of Netgear have been cratering, so they are asking their GOP buddies in Congress to help shut down TP-Link's US business. Capitalism is good, until you need the game rigged in your favor. Question: Has anyone used TP-Link for small or medium enterprises? How did the installation go (models, qty, client density, etc.), and how is it going?
Porsche924 0.0Went from a Timecapsule to two Decos in a mesh and its been great.
Cae_len 0.0Look at firewalla gold pro ... Best router I've ever used in a long time... Understand this is a router only though... This doesn't provide wireless access and way above your budget . Would also need to add access points for that. I don't think you will find anything decent in that price point TBH. ... I had decent luck with TP link deco as well but I find that it could have some better features... Unfortunately if you go with consumer routers you will always find them lacking....
Choub890 0.0\+1 for deco, I have 3 of them at home (one on each floor) and it works great!

Chrono978 0.0Don’t bother with TP Link Deco either, ok router but not great Parental Controls.
cmajka8 0.0I only have the Deco so that’s all I can speak to. Ive been really happy with it. Easy to set up, works really well, and no issues after over a year so far. It has all the capabilities you would want, including easily setting up separate networks for guest, IoT devices, etc. you can assign your devices to specific access points or use the mesh functionality. Also very easy to expand if you want to add more access points.
I have a TP-Link Deco mesh system that was easy to set up and easy to expand. No issues so far for 2 years
edavana 0.0Wifi extender would reduce the speed considerably. Best option : Mesh network. You'll need two minimum and add on would be 2.5K per mesh router. TP link Deco is what I am use. Second best : buy another wifi router and connect it with the original through ethernet cable. You'll have a different wifi name for the network from the second router so you'll have to switch between connections.
farmyohoho 0.0Tp 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
