TP-Link Deco X20 WiFi 6 Mesh System (3-Pack) - Up to 5800 Sq.Ft Coverage, 6 Ethernet Ports, Wired Backhaul | Whole Home Wireless Network for Streaming, Gaming & Smart Devices

Our Installation: We subscribe to a 800 Mbps Comcast plan which actually tests at 900 Mbps. Our 1975 tinker toy construction (drywall/plywood) L-Shaped, single-story ranch 2300 sqft home has a crawl space under the footprint with an attached 3 car garage and backyard patio/swimming pool area.The 5800 sqft wi-fi coverage (overall average wi-fi data rates = 500 Mbps includes smartphones) is more than adequate for our needs (no gaming, 2 TVs (family room and garage) with 5 Alexa Plus/Echo Dots, roaming smartphones/GEN 6 laptop, desktop, multiple switches/plugs, Xfinity/Comcast owned Home Security router and irrigation controllers).We tested the Deco X-68 (2-pack) with dedicated 5GHz tri-band, finding the Home Security upgrade solicitations to be annoying vs the lifetime included Home Security bundled with the X-20 (very good). Since we have a crawl space, wiring backhaul CAT 7 cable (chosen if ISP plan ever exceeds 1 GIG) through a TP-Link unmanaged 5-Port switch made longer term usage/performance sense. Note: also connected TP-Link USB/Ethernet adapter to switch for HP Pavilion Desktop (ethernet adapter only 100 Mbps)...increased wi-fi data rate from 250 Mbps to wired 500 Mbps. Aside: The Mrs wasn't thrilled to call the local Fire Department because I was stuck trying to get out of the crawl space!900-600-300-(50%)900 = ISP subscription signal data rate directly from Arris SB8200 cable modem to desktop and laptop. ALERT: The cable modem has 2 1-Gigabit ports, but ONLY 1 is operational unless you upgrade your Comcast subscription plan (not knowing cost me a lot of time plus the Comcast technician during his visit didn't even comment on this condition..."we don't troubleshoot 3rd party equipment" Oh you don't? = I collected $250 in refunds FROM Comcast during this installation process) Suggestion: We put a book cover around cable modem on bookcase to hide it, but it's still accessible if we need to manually reboot (see photo).600 = Signal loss (300 Mbps) connecting cable modem to Main Deco and backhaul ethernet cable wiring 2 nodes/satellites. Both our desktop and Lenovo Gen 6 laptop speed test at 600 Mbps by each Deco X-20 location. Note: Gen 6 laptop "wi-fi data rate" is also 600 Mbps at each location which implies the Gen 6 new standards firmware is performing well. Also smartphone Pixel 3A XL wi-fi roaming throughout house speed tests at 500 Mbps.300 = Signal loss (300 Mbps) speed testing wi-fi on the Gen 6 laptop in remote areas: Garage & Patio areas performing at 300 Mbps50% Loss Non-Wired Backhaul = Using the Deco X-20 routers to transmit ISP signal through its 4 antenna/radios vs backhaul wiring, decreases signal by 50% at all locations...ie signal in Garage by Android TV drops from 300 Mbps to 150Mbps (basically triggered decision to run ethernet cables or reinvestigate tri-band solutions)Deco APP = Extremely well designed, absolute piece O cake to use. Provides me all I need to manage the entire network (connected devices/mac addresses/connected frequency rate (2.4 vs 5)/locations/wired not wired) by online/offline plus separate listing by locations) Easily reboot All Decos, optimize network, turn on/off Guest Network (works well with Alexa skill) to include 2.4GHz and/or 5GHz signals+++ = Just terrific!TP Link Support = 24/7 phone support with very caring and generally very competent technical troubleshooting. I made a very costly set-up error by testing QoS (Quality of Service) by entering 100 Mbps download (I recommended to TP-Link about adding WARNING for this input) because it basically puts a governor on your real available data rates. Xfinity and I got tired proving I was getting the subscription rate we are paying for!Bottom Line = For our installation and needs, we couldn't be more ecstatic with the upgraded High-Efficiency/High-Value mesh routers for $220. Note: Switch, USB/Ethernet adapter, CAT 7 cables = $75What triggered this entire project was our purchase of a Gen 6 enabled Lenovo laptop. Of note, BOTH your router and connected device need 802.11ax or Gen 6 chip sets to tap OFDMA (Orthogonal Frequency Division Multiple Access)/RU (Resource Units) efficiency and WPA3 security (160 MHz channels (not supported in X-20) and MU-MIMO (Multi-user, Multiple Input, Multiple Output = currently vaporware) adds nothing to our WLAN performance needs). I believe, although cannot unequivocally test, the Gen 6 enhanced data rates are performing extremely well. All other legacy devices are solid with the new available signal strength and strong data rates near the 3 APs (Access Points). Our Orbit hose/timer up the back hill tucked under the redwood trees receives 75 Mbps!6E chip set devices will be rapidly appearing in the marketplace over the next few years. You need BOTH the router and device to include 6E chipsets to utilize the new 1200 MHz, 6Ghz "pristine spectrum". As we Long Term Evolve (LTE), our new Deco X-20 (3-pack) will easily last 3 years or longer as our devices are steadily upgraded to 6E.We highly recommend!
