Cause every once in awhile the extender loss singl.** A: Extenders will definitely allow connections from further away, BUT they always cut your speed exactly in half. So an extender is just that a range extender, not a speed increaser, it decreases speed. However the range extension can prevent dropouts so it acts like it is a speed increase but it is really just preventing dropouts (and remember it always cuts your speed in half). On the other hand a Mesh system is actually 2 (or more) routers that you place in 2 different spots and so it does NOT start by cutting your speed in half. It is full speed. But since your computer (or wifi TV or doorbell etc) is closer to one of the 2 (or more) mesh spots it will also extend your range for that reason, and prevent dropouts for that reason. And the closer your device (computer, laptop, etc) is to the router, the chances are the faster the internet speed could very well be (for instance on the ookla online speed test website). BUT an extender works with your old router. A mesh system IS a router (actually it is 2 or 3 or more routers), so it will not work with your old router. The routers are built in to the mesh system. With an extender you need a router (your old one for instance), the extender(s), and a modem. With a mesh system you just need the mesh system and a modem. You do not need a router (because it is built in). **Q: how far from the base can a node be placed and does each node have to talk to the base or do they talk to one another in a chain?** A: The nodes talk to each other to form the mesh network. The setup app will guide you in the placement of each node. My base is in one corner of the downstairs, I placed one node in the kitchen which is in the middle of the house and the other node upstairs. That gave me great coverage everywhere in the house. **Q: I just installed this and apple is indicating wpa/wpa2 (tkip) is not considered secure. how can i configure this to wpa2 (aes) or wpa3 security type?** A: Hi!

My old ASUS router + extender setup left me with zero bars in the master bedroom, garage, and back patio. After fighting it for years, I grabbed this Deco S4 3-pack on a Prime Day deal for $119 and it’s been flawless for the last 14 months.Coverage & speedPlaced one in the basement office, one on the main floor, one upstairs hallwayFull bars everywhere now – even the detached garage 70 ft away pulls 180 Mbps down on 5 GHzReal-world speeds: 450-550 Mbps next to a node, 220-300 Mbps in the farthest corners (on a 500 Mbps fiber plan)Zero buffering on four 4K TVs streaming at once + two kids on Fortnite + my WFH Zoom callsDead-simple setupTook 12 minutes total with the Deco app (literally plug in, scan QR code, done)Seamless roaming – phone/laptop walks from basement to backyard without dropping a single YouTube frameGuest network, parental controls, and QoS actually work and don’t require a PhDReliability14 months uptime, zero reboots neededSurvived two 4-hour power outages (units just come back online when power returns)Runs cool and silent (no fans)Only two tiny gripesNo dedicated backhaul band (it’s AC1900 tri-band in name only – shares 5 GHz for clients and backhaul), but with wired backhaul option or good node placement it’s never been an issueNo USB port or fancy features, but I don’t care when it just worksFor $119-140 the 3-pack is stupid cheap compared to Eero or Nest (which I tried and returned). If you have a big house, thick walls, and just want rock-solid WiFi that you never have to think about again, buy these before the price goes back up. Already convinced three neighbors and my parents to ditch their old routers for the exact same kit.10/10 – best money I’ve ever spent on networking. My WiFi problems are officially dead and buried. ### ⭐⭐⭐⭐⭐ Superb value and coverage, but place them smartly! *by on Reviewed in the United States September 3, 2024* I have used the 3 node Deco S4 for just over 4 years now. It has been reliable and stable, but I wanted to share some recommendations to get the most out of it.1. Regularly check the Deco app to see if the network needs to be optimized due to interference. I find doing this a couple times per week helps a lot and it is my first troubleshooting if speed drops.2. Restart your modem periodically, at least once per month3. When setting up, at first just turn on the main node. Then use a wireless device like an iPad and run a speed test as you move away from that location. Very close to it you should get close to your contracted speed from your internet provider (in my case about 400Mb per second). The further away you move the speed will drop, more so when you pass the signal through walls or other obstructions. When you get to a spot where the signal is starting to degrade (in my case 250Mb per second) place your next node. Repeat for the third hopefully in a way where you achieve good coverage at a reasonable speed. In my case I can get a minimum of 100mb per second across an area of 10,000 sqft across 3 levels by spending some time on the placement. Keep in mind that the further away you place the nodes the more thinly you are spreading coverage. Remember, having a strong signal to a remote node doesn’t mean fast wifi if the signal TO that node is already degraded. Likewise, if you place them too closely you will just create network interference due to overlapping. I found the coverage below a node is better than above so given the choice place them on a higher floor. It may take a little trial and error.I did not see a need to do any wired backhaul and I am HD streaming all TV/Netflix, etc. with tons of smart devices.One thing I did notice is microwave ovens really interfere with the signal so best to keep away from them if possible.Setup is really easy and the app gives you everything needed to manage your network. I’m still very happy after 4 years of using this product. Unless I get 2GB service in my area I see no value at all in a newer generation system. ### ⭐⭐⭐⭐⭐ FAST, simple setup, cheap mesh solution *by on Reviewed in the United States January 22, 2021* After doing a lot of comparison shopping, I ended up settling on the TP-Link Deco S4. My biggest factors were price, reliability, and range. I have a three floor 4500 sq/ft house built in 2003. The Verizon Fios Gateway router worked, but it suffered considerable slow down as I got to the extremes of the house. With the new three node Deco S4, I get full speed internet at every floor and extreme. Previously, I was able to get 100mb/s maxed out at the router with minimal traffic, but dropped down to 10 mb/s at the extremes of the house, especially the basement and some bedrooms. With one of these on each floor (main on middle), I range from 95-120 upload and download (paying for 100) on all three floors depending on time of day. Interestingly enough, I haven't suffered much dropoff in signal strength with each mesh node as opposed to the main wired unit acting as the router. I've read countless time that unless I'm using a wired backhaul that there would be signal dropoff at the mesh points, but I haven't witnessed any significant drop. I also purchased this system as it had ethernet ports for backhaul (if I needed to improve speed) and accesspoint use on each node, but I don't use any other than one at the main router for my Phillips hue bridge.The design is simple and clean. I was debating on saving $10 and getting the M4 (identical internals), but figured I was already scraping the barrel on price point so may as well get one that wasn't as much of an eye sore. These are clean, simple, modern, and much better to look at then the Fios provided router.The app is simple and intuitive and makes most of the decisions for you. It ran me through the setup very easily. It has parental controls and allows me to prioritize devices as well as setting up a guest network. However, what was most essential to me was the ability to turn off 2.4 or 5ghz signals if I needed to set up a product that only worked on one (usually older products that use 2.4 only). This app is mostly for people that have basic technical skills, but not full on IT networking knowledge.I chose to replace my Fios router entirely and run ethernet from the Verizon modem (optical network terminal) instead of coax so I didn't have to run the Fios router in bridge mode. I called Fios tech support and the person switched the feed to ethernet in five minutes. Now I don't have to rent my router and have much faster internet without relying on bridge mode. If you aren't comfortable with running ethernet and swapping it out at the ONT, you can use the Fios router and connect the Deco S4 to their router instead. This also allows you to keep your cable box functionality such as guide and on-demand without a MOCA adapter. I have no such plans as I'm dropping cable for YoutubeTV.On average, my house has around 40 connected devices from Phillips hue bridge/bulbs, Ecobee thermostat, Ring products, several Nest and Echo devices, five smart TVs, smartphones, tablets, and laptops. Don't buy into the hype that you need wifi 6e. This supports gigabit+ speeds and the dualband is more then enough to maximize efficiency. In addition, you can add or swap out mesh points to this system at any time from any Deco system (E3, M4, M5, P9, etc.). You can literally improve on this system in the future if desired. This was one of the best purchases I've made in a while.Update 2.4.21: I recently switched to 200mb/s from my ISP (it is the lowest package they offer when only purchasing internet). With this, I've noticed download speeds at the main router at 270-300 and 300+ upload depending on network traffic. I have seen more noticeable drop-off at the mesh points with this speed, usually 170-230 download and 200+ upload on my first mesh extension node, and 160-200 download on the one in the basement. I also have the biggest variance in upload speeds with this one at 45-120 upload, depending on time of day and network traffic. However this was also the location I had the biggest issue with previous to installing my Deco S4 system. In general, I am still getting amazing speeds, far exceeding what I'm supposedly paying for, extremely stable at every location of my house including the far extremes of my yard. I have can rely on blazing fast reliable internet throughout my house and not have to have wired backhaul to achieve it. However, I can now see why some individuals suffer noticeable drop-off with higher internet speeds at the mesh points. If you figure the drop-off as a percentage and multiply it times the speed, the difference will be more noticeable at the ghz speeds. Overall, love this device, how much faster my internet is and how I am not paying my ISP for their outdated routers they try to dish on unknowing consumers. Best purchase I've made in years. ## Frequently Bought Together - TP-Link Deco Whole Home Mesh WiFi System (Deco S4) – Up to 2,000 Sq.ft.
