    Works flawlessly! It was used to replace a very old Apple AirPort Extreme. The coverage works very well in a 2 story house with a basement, in all areas. The speed is outstanding and it functions wonderfully. It was easy to set up. It was paired with a new DOCSIS 3.1 cable modem via a long ethernet cable. It supports multiple TVs streaming, people working from home and people using their phones/pads, all at the same time without hesitation.
    I am unsure about the best antenna orientation. This unit supports “beamforming”. In some documentation, it says to have all antenna straight up for this and some says to angle them as fits your situation. I ended up using a combination of angled and vertical.

    I wanted a more secure WiFi router while also saving money on the rental from my cable provider, so I was suggested to purchase this by a very experienced tech and cyber security wiz. Now, I personally don’t feel that I know much about anything technical these days, but I have really enjoyed this so far. Performance wise, but more than anything I REALLY love the security of the back-office type of controls the TP-Link gives you.

    PERFORMANCE
    Now, my current home is 1500 sq ft and a split level home, so most of the areas I use WiFi at home are never too far from the router. I placed the router right on the TV stand underneath the TV so that certainly is as close as it gets. When I’m upstairs (technically 1.5 levels up from the router) I still seem to get fine enough WiFi when I’m browsing on my phone. I will say that the WiFi randomly cuts out for me, but, this is definitely an issue I had with my previous equipment so I don’t blame the router itself, it is my provider. Or the wiring outside my house.. not really sure. I have noticed however that when the service does go out, ever since changing to the TP-Link, the service returns much faster and I never have to reset it. With my old provider-provided router, it would be out for hours and I always seemed to have to manually reset the equipment. So in summary, the service and performance for me has been exemplary!

    SOFTWARE
    The primary reason I got this was to make sure nobody could hack into my WiFi. With other routers, I am not sure if the same service is available, but this was the first I’ve ever seen it. Yes… we all know that WiFi is password protected. BUT. Someone can easily hack into it, right? Well not with the TP-Link! You can access the router security through the routers IP address, and you set a password for that as well. The user interface is pretty simple for even a dolt like myself to understand. You can control who can access your WiFi by using a blacklist or a whitelist. A blacklist means that all who have the login details *except* for specific IP addresses you’ve blocked can access. A whitelist means that ONLY the IP addresses you have added to your list can access the WiFi. I am using the whitelist, since I do not want anyone random or unwanted accessing my service. Let me tell you, it works perfectly! Sometimes I forget that I have this setup, and I have tried many times with many different devices to try and access the wifi… heck, even the guest network, that I thought was specifically setup for this, doesn’t seem to let random users access it. It also shows you who is currently accessing it, although I find that feature doesn’t seem to be totally accurate sometimes. I give the software 5 stars for the simple fact that it is so easy to control access through it.

    SUMMARY
    Overall I am very happy with this purchase. It does what I want it to do, very securely. Setup was a little confusing because if I recall correctly, nobody could access it until we were able to get into the back-office software and setup password first. Other than that I really have had no issues and enjoy using it. When I need to change a setting it is super easy to get in and make any adjustments.

    Installed a few months ago. Has been very reliable. Good coverage through out the house. I have it installed in the basement and I get a strong signal from the second floor. My internet limit is 500mb/s, I get the full speed when I’m close to the router, up on the second floor I get about 200 mb/s. Easy to setup, set a few port forwards for security system, and easy to update.

    Steady Performance, But With Some Quirks

    I’ve been using the TP-Link AX1800 WiFi 6 Router (Archer AX21) for a bit, and overall it delivers what it promises: solid coverage and faster speeds than the older WiFi 5 units. Setup was smooth—TP-Link’s Tether app walks you through the process in minutes, and the router connected cleanly to my ISP. Once running, I noticed noticeably snappier streaming and fewer hiccups when multiple devices were active, which makes a real difference in a busy household.

    The build is compact and low-profile, which I like since it tucks away neatly on a shelf without looking out of place. Signal strength is good across a mid-sized home, with no major dead zones. It also supports mesh expansion, which is handy if you need to grow coverage later. The router is Alexa-compatible, though I haven’t found much real-world use for voice controls beyond some novelty.

    That said, there are a couple of things to keep in mind. The interface is a bit basic compared to more advanced routers—if you’re looking for deep customization or advanced QoS, this may feel limited. Also, while speeds are solid, don’t expect it to match higher-end WiFi 6 or 6E models; it’s more of a budget-friendly step up from older gear than a top-tier performer.

    Bottom line: A reliable, affordable WiFi 6 router that handles everyday streaming, browsing, and smart devices well, though power users may want more advanced controls and top-end speeds.

    Great range, reliable and easy to set up and run. It has worked perfectly ever since I did the initial setup and has operated glitch and trouble free ever since. This isn’t my first TP-Link Router, but is by far the best Router I’ve ever owned.
