"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."

"Then you can buy a 30$ TP AC1200 router on Amazon and boom you save $10 a month."
"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"
"The TP Link Deco mesh systems also provide good speeds at a much lower cost, so that would be my go to."

"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."

"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."
"rubbish app that won't let you change settings 9 times out of 10"

"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."
"Just needed to turn off fast roaming since it was cutting off uploads randomly. Guess the house is too small for 3 APs."

"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 :\"

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

AromaticBenzen 1.0yoo same ISP and internet package and i got a Mesh WiFi as well. bought it off from India as the sellers here just rip you off on any networking devices. i got TP-Link Deco M4(INR 2599 = NPR 4155) via third party and paying the added customs + vat + delivery fees costed me around NPR 5200-5300 which is way cheaper than buying it here for NPR 8750-10000 each. if you are only planning on buying a single mesh router, i would advice to just get a normal router like TP-Link Archer WiFi6 instead and use it as AP mode. but if you plan on having multiple routers, get a mesh one with WiFi6.
Fred_Stone6 1.0I have a single erro router in the middle of my house it supports mesh, I would like to have more coverage in the yard, quite like the tplink mesh units like. https://www.pbtech.co.nz/product/NETTPL9402/TP-Link-Deco-M4-AC1200-Dual-Band-WiFi-5-Whole-Home?qr=web-share
jk_here4all 1.0Go for Mesh. If you are looking for more than 500Mbps connection you might need to connect the units using LAN cables. I used this one for my parents house. https://www.amazon.in/TP-Link-Deco-M4-AC1200-System/dp/B07KJ2TDMR/
Yeah needs to be plugged in. You take LAN out of your main router and connect to one of the units (base unit). Then the second unit can connect wirelessly to the base or via LAN cables. Something like this 1. Router ----- Deco Base )))))))) 2nd Unit 2. Router ----- Deco Base ------ 2nd Unit \--- LAN connection )))) WiFi backhaul Remember when using WiFi backhaul, the max speed of the second unit will depend on the strength of Base unit's Wifi signal where the 2nd unit is placed. My set up is like the router is upstairs computer room. Base unit directly connected to router via LAN cable. The 2nd unit is kept near the stairwell which covers all the downstairs. The range of the units are way better than the BSNL supplied ones.
Suikerspin_Ei 1.0I had a TP-Link Mesh system (Deco M4), not possible. Maybe on their routers.
betelgeuse_92 0.2I used to have a TP-Link AC1200 router. I’m not sure if it was because I was torrenting for a longer period or more torrents, but the router would throttle to 1 Mbps. I’m not sure why this happened, but when I rebooted the router, it would work fine again. This happened a lot, but it happened less often with the ASUS router.
broly78210 0.2Yeah, you'll have to get the new free modem that isn't a Wi-Fi/modem combo. Then you can buy a 30$ TP AC1200 router on Amazon and boom you save $10 a month. it's what I did, I told them I was switching to frontier for 29.99 and the agent lowered me to $50 a month with the wifi router, and told me to return the router when I got my own. I dragged my for two months but it paid for itself. I'm not techy but It was easy
Dry-Organization4901 0.2I live in a 4600 square feet house. The modem aka the main router is downstairs and the download speed is 300 Mbps and upload speed is 100 Mbps. The router which is near my room upstairs gives me a speed of 30 Mbps the name of the router is tp link ac1200. What router do you recommend budget $300.
Pl5y3r13 0.2Yes, ac1200 alam ko dual band din. Prehas naman sila TP link so compatible sya. Siguro CAT6 lan cable nlng bbilhin in case.
Endawmyke 0.1I 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.
ShiftSpecialist664 0.0I have a 3000 sq ft home and tricked tplink 3 deco unitsand am disappointed with it. Numerous units drop connection and it doesn’t cover my entire house. My 5 yr old orbi system never had these issues
