No need for my extender anymore.

This is my second TP-Link router, the first being an Archer A7. My wife teaches from home and my 4th grade daughter is remote learning. Before the winter break we had a unexplained internet slowdown and high lag one morning (which magically disappeared). My wife was concerned enough, she gave me the go ahead, or excuse, to replace our current wifi setup.Our old Surfboard modem was going on 8 years old, and we had the A7 router. These ran using a 100 Mbps Comcast account. The A7 by itself covered most of our house, but would really slow down, sometimes drop out, in the opposite corner of the house in one bedroom and a bathroom. This was on 2.4ghz. A OneMesh extender took care of that issue.The AX21 does not need an extender. I get 80-85%, maybe a little better, of full speed in two rooms the A7 had issues with. Oh, did I mention that was on 5ghz? The router, by itself, for sure has really good coverage. No need for my OneMesh extender anymore.Since I was already familiar with the Tether app setup wasn't an issue. The only problem I ran into was an old laptop couldn't see my SSIDs anymore. Updating the wireless drivers fixed that. Maybe something to do with the AX protocol?So, the Archer AX21 fills our needs. It covers the entire house well. With only 100 Mbps internet it's speed is about the same as the A7, but with better coverage and much higher speeds at distance. We'll have to wait and see about reliability as time passes by.

Router Firmware is Better but not entirely stable (QoS issues = Turn off QoS)

Summary: Particularly if you want to run what I call a "cheap mesh on the fly" system, mating this Archer AX21 router to TP-Link's RE-series Wi-Fi extenders that can support OneMesh+SmartConnect is a great way to go...just turn of QoS in the meantime (easily done with their robust Tether interface). Comments: Whenever a company puts out a lot of hardware variations along with a lot of software options, you have a testing permutation nightmare, having to test a large host of hardware with a huge number of variable implementation options. In my case, I tried to run the AX21 with the full suite of options: SmartConnect (single Wi-Fi name for both bands), OneMesh + WiFi Extenders (RE200+RE220), and QoS. Well, with QoS turned on, the router cut my download speeds in half and then hard crashed one evening (I've only had the router for a bit over a week). Frankly, it bothers me that end users become a company's testbed....but it's more important that the product works...and in that regard, the AX21 is superior to my prior Archer A6 in terms of speed and WiFi coverage. I reported the QoS issue so I hope TP-Link will investigate and correct the system instability in a future firmware update.

I recommend this product

Easy setup and great speed

Great. Setup using the app and web page was super easy. Speed tests using WiFi 6 enabled devices is amazing.

Make sure you need wifi 6 and not want wifi 6

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.

Great performance but beware "smart connect"!

Great performance - WiFi 6 is real, distance and signal strength were much better than with a new comparably-priced WiFi 5 high-performance router. Setup is made unnecessarily difficult in that requires the user to type in the default password or scan a QR code. However, the font for the default password on the bottom of the router is so small it is almost impossible to read. The quick-start instructions say you can scan a QR code, but fail to note that the QR code is not on the box or on the router, but instead on a little separate slip of paper in the bottom of the box.Review update: after a few days wifi seemed very slow. Testing revealed that the problem was TP-Link's "smart connect" feature. As with any dual-band router, you can set the slow 2.4GHz band and the fast 5GHz band to the same SSID. Normally this would allow your device - laptop, phone, etc - to choose which band to use. Smart Connect is supposed to optimize network performance by allowing the router itself to decide which band each device should use. But what Smart Connect actually does is the reverse of optimal: it only allows one device to connect to 5GHz, and kicks everything else to 2.4GHz! Even if that one 5GHz connected device is idle, every other device is locked out.There is a long thread on the TP-Link user forum about this bug in several TP-Link routers, with users complaining and TP-Link tech support people just saying "that shouldn't happen"! In any case, to fix it problem go into the web-based network settings page and turn off smart connect. You can then manually give the 2.4GHz and 5GHz bands the same SSID, but keep the check box for Smart Connect in the off setting. After this little adjustment, everything worked great again.
