    Wish it was a stand up for the area that I have it. My only downfall but I don’t really have a router to show it off like it a luxury car. I have a router so I can go search the web, so I can get a smart wifi Luxury car to show off to people. This router helps out, I actually do need a wifi 6 router, because I have over 30 wifi products. Now I a heavy traffic day I am reading high 300, with a ping of average 8.Wifi 6 is best for those that have a lot of products on the internet at once constantly pulling. I have well over 30 products within my own home that requires wifi all the time to work. Do not get it thinking that it will make gaming better. It will if your current wifi system is 6+years old. cause at that point you should be replacing your wifi router for a more up-to-date system. Just watch Linus Tech tips and Linus Media on youtube, very helpful in learning about computers and techs.

    Update 2: Firmware issue fixed my dropped connections in the morning. Ran speed tests. Same speeds. Seems to be same signal strength.Update: Well…I’ve set it to reboot every day now. And oddly some mornings there’s just no wifi signal. So I have to go over and reboot it. I’m thinking of updating the firmware package to see if this resolves that issue. I’ll post once i have this issue fixed.I bought a Nighthawk prior to this. But the nighthawk was a pain setting up as you had to get an app, create an account, and then I still never saw great speeds even on 5ghz. This thing blows that nighthawk out of the water (and was about $30 more). The nighthawk also dropped my cisco vpn alot. NOT COOL.With this router:Signal is great. I can walk down the street a few houses and get signal (not great, but usable). It works great for our square 2,300sqft house just fine. I bought an extender – but found we didn’t need it.Speed is great. I get full use out of my 200mbs connection to my provider.2ghz I get about 60mbs. 5ghz I get 210mbs.The modem I’m using is a Motorola 24×8. It works well with that.I haven’t seen any signal drops. My VPN stays connected all day (which is rather important these days given covid).It runs cool to the touch (big factor as I’m always paranoid about house fires and cheap poorly built electronics).I have it auto reboot every sunday (which is a great feature you can set in the menu).I’m using the firmware out of the box. I did not update the firmware. With routers, I tend to only update the firmware if I see a problem that needs resolution.Setup was easy. Plug in router to modem. Turn modem and router off. Turn modem on. Turn router on. Pair computer to wifi. go to in browser. setup wifi and password. Done. Great interface too on this router.Very happy i brought this. Should my experience turn the other way I’ll be sure to update this review.

    Like my heading says, I had a $350 fancy Asus gaming router than died and I could not afford to replace it so I saw this one when on sale and figured I would try it. Even though the coverage specs are double on the Asus plus 8 antennas, this covers my same area even back to the shed. Only main difference is no gaming settings and not tri band. Still my gaming is fine hardwired and the wifi handles all the same devices, wif cameras, phones as the Asus.

    This router is packed meticulously inside the retail box. Once unpacked and plugged in, it walks the user through basic, and/or personalized, setup. The web interface is well crafted, and finding various features of the router is relatively easy. This router improved the transfer speed of my devices by about 50%-80%; compared to my old ac router. The signal/speed is acceptable up to 60ft in all directions through floors and walls. Physically, the router is built well and relatively small. It is sturdy, for a delicate electronic equipment that is.I recently bought a NetGear AX router. I returned it partly because it lacked basic quality, and primarily because it stopped working after five days. The NetGear router gave me a base of comparison for this TPLink router. I am now convinced that this TPLink router is a superior product.

    Router from spectrum needed to be reset every day and the range was terrible. This router is the complete opposite and has worked flawlessly in my 1000 sq ft apartment since I bought it a month ago. I have around 30 devices connected at all times between my 2G and 5G connections. The Speedtest in my pictures are from the furthest point from my router in my apartment.

    Bought this not needing a new router, or so I thought I didn’t need one. Had been sticking with a Linksys ea7500 bought five years ago. Decent device, but I’d been noticing stuttering lately on my devices and buffering on my streaming. Saw mesh devices and higher end routers that were nice but were pretty much overkill for what I need. We live in a small 1500 sq foot home (don’t judge, it’s still worth $700k+) and just need a strong signal and wifi 6 to keep up with our newer devices. Checked out reviews online and saw this as the best bang for the buck. And at $80 I figured what the heck. Amazon driver launched it onto my porch, which crumpled the box. But it made it through unscathed. Swapped it out for my old router, plugged it in, and spent about two hours getting everything to work with it. Didn’t realize how many smart devices we have running in our home. TV’s, computers and phones were easy to flip. Smart switches and thermostats were a PITA. Can’t really fault the router, but some of the devices didn’t want to play nice with our new toy. Finally it done and started testing. TV’s seem to be running fine, my laptop seems zippier and Alexa is talking to all the lights, swiches and fans in our home. I think the biggest test will be what I don’t hear though. Wife ‘n kids generally don’t give you kudos for what’s working well. But you hear it when things are going crappy. Guess no news is good news. This looks to be an excellent router for an average sized family (all adult and lots of devices) in a small to medium sized home. And although I’m a techy person, I’m not a big fan of tweaking routers. But there’s enough here to allow me to play around if needed. I’m certain you’d get a bump in performance buying a $200+ router, but doubt I’d notice the difference. Bottom line…Good, no nonsense Wifi 6 router at a heck of a price.

    I had. Tp-link C9 router previously for 6 years. Support for great. Performance great. Unit was becoming less stable and like other user reported after f/w upgrade or age front led lights just got very dim. Can’t complain with 6 years use. Found the AX1800 to be the sweet spot for average home. I have the tether app, but wanted some more detailed customization (I’m retired tech) and used manual install. Had no issues. Menu and interface was same design. Was suppressed to see unit supported bridged 2.4 & 5.0 mode. Makes wifi use much easier. Nice bonus. Front Leds bright, but not obnoxious and can be on night timer or off. Since I only have 50mb cable, I didn’t see dramatic performance increase, even on our 2 wifi6 devices. What I did see was stronger signal strength! Have only had to reboot unit once in 1st month, we lost internet from cable feed. After reboot still no internet, and minutes later internet came back, so it was likely cable provider all along. I did buy inexpensive 4yr ext Warr because cost was so low and last unit lasted 6 years. Install was easy, we started with dual wifi and 2 passwords and changed to the single bridged wifi, one pw. Yes, had to redo wifi on all home devices one time. Took maybe 20 minutes extra. Worth it for easier sign on, less confusion. That feature along makes the cost and small hassle worthwhile. Coverage is 4 bars end to end house and basement witn unit somewhat in center of house on main floor. For my older yes,I do wish the indicator Leds had icons as the led or bigger indicator icons. Not a crisis, as most the time the nononternet led turns orange/red when a problem. I do refer to the Tether app for basic monitoring. Hard to best cost / value / performance.

    Of the thousands of reviews here of this class of products which include AX10, AX21, and AX50 (and perhaps many others) I think this router is the best in terms of sound design and engineering, i.e., appropriate cooling, not overreaching on features, security, etc. TP-Link itself seems to me to be a technological leader in the “inexpensive home personal WiFi6” field 🙂. Setup was easy; it took about 1 hour. One does have to go through every subsection of the GUI to close potential security holes (even the advanced section.The performance thus far is very good. I was having some issues with the children’s Zoom blocking and they seem to be resolved. I may write an update if this changes.

    Can’t speak to its router capabilities, as I’m not using them. My house is wired for ethernet, but needed better wifi coverage in parts of the upstairs for those pesky mobile devices, and my older wifi base station was downstairs. Since I have the advantage of a wired network to plug into, I just added this unit in a room upstairs, set as an access point, and now my wifi coverage is excellent all across both floors of the house and even outside where I couldn’t access it well before.Plus the speed takes full advantage of our 250Mb internet connection… bonus!

    Long review but hopefully helpful:Bought this to replace an aged Airport Extreme and give my Oculus Quest 2 a better WiFi connection. So far so good.Set up was okay but I had some trouble getting the Ethernet light to go green despite all the others being green and I was unable to get online via wired or wireless connection. If you reboot your modem and this device, go make coffee or something when it is starting back up because the router takes a while to restart. The light finally went green but it did feel like it took an inordinate amount of time.I understand the frustration that comes with setting up these new things and the rage factor sometimes enters the picture. If it does: unplug the cable modem and the router, leave everything unplugged for 5 minutes, plug in the cable modem and wait until it is fully booted up, plug in this router and walk away for a bit. Give it 5-10 minutes and hopefully you’ll be good to go.The interface looks a bit dated and clonky but most do. Seems the least priority is given to creating a clean, attractive interface for all these things, but coming from an Airport Extreme where you have essentially no features to work with, this is a dream. The ability to edit the names of the clients is something I was never able to do before and it really makes a difference.I wanted something with the ability to kick clients off the network while I am using the Quest to ensure it has no bandwidth competition with devices that are not in use at the time the Quest is being used, but then put them back on without having to jump through hoops, re-entering passwords and such. I have a lot of devices on my network and while they may not be in use, they are still hovering around and eating up some bandwidth even while idling.This router allows that in an easy peasy way but the icons used are confusing. First, if you go to the Network map, clients section, you will see a list of all the clients on your network. You can click the pencil next to the name of the device and change it to make life easier. On the right side, if you click Block, that client gets blacklisted and cannot connect to the network. If you click View Blacklist, you will see all of the blocked clients and there is a garbage can icon on the right. This is a confusing and poor icon choice because most people would think that this will remove the client entirely. It doesn’t. It simply puts the client back on the whitelist. It’s a great thing to have, for example:Let’s say you have a Zoom meeting and want to ensure that there’s as little connection issues as possible. You can block all other clients on the network that are not needed and have all the bandwidth to yourself for your meeting and when it’s over, just click the garbage can on each device in the blacklist and poof! they are all able to connect again.I am not really understanding the point of the QoS feature on this device because in the past when I’ve set up QoS in a work environment, you are able to directly allocate bandwidth to devices. Ideally, this would be what you would use if you had a Zoom call rather than kicking clients off for a time. With this router’s QoS, you have two choices: On or Off. Each device listed has a Priority switch that is turned on or off. You can turn on the Priority switch for one, some or all devices, but there’s nothing else, so you have no idea how bandwidth allocation is implemented here.Under the On/Off switch for QoS, there is a bandwidth allocation box for both upload and download with each set at 1000. You can change this number, but again, it doesn’t tell you how it will divvy out that bandwidth to the clients. If you only have one device with the Priority turned on, you are left to wonder what that client is getting as opposed to other devices on the network. That’s kind of a shame because you can prioritize a device for Always or for a couple of hours. Would seem the perfect set up for a Zoom meeting as you can give Priority to your device for a set amount of time and the router will release that restriction at the end of the hour or two or whatever you chose without you having to interact with the admin page at all. Unfortunately, you cannot enter times: i.e,. Priority from 10 a.m. to noon. You can choose Always, 1 hour, 2 hours, or 4 hours.I’m not sure what people are talking about regarding monthly fees for Parent Controls. I don’t have kids, but opened it up and you can add a child’s computer as a device, block certain keywords from being searched online and limit the days/times that your child can get online. I didn’t see anything about fees or payment for those features.I have noticed more zip in my Quest 2 since setting up this router and am quite pleased with it so far. I set up a 5ghz network set to AX only for the Quest’s exclusive use, a 2.4ghz Guest Network for all the Echos, Kindles, switches for lights, etc., and a 2.4ghz network for laptops, iPads, etc.
