Update 5/21/24: We just dropped our ISP and went with a new Fiber Optic 1GB ISP just on our street. no matter if you have a cable modem or a Fiber Optical connection, they all terminate to a standard ethernet connection. Our old cat 5e/6 ethernet cable works fine with this and were are getting ~800mbps upload and 725 mbps download speeds on wifi. (wired ethernet will almost always be fastest, but, our speeds are excellent for our wifi setup with the AX3000). I swapped out the WAN cable from my old Motorola cable modem, plugged in the ethernet cable from our Fiber Optic box, rebooted the AX3000 and bingo, back in business. It was that easy. The tech doing the installation here said he wished others would choose the right Router for higher speed internet services and he said he knows about the TP-Link routers and that the AX3000 was a great choice for our new internet service. ---------------------------------------------------------------------------------------------------------------------------- After about 10 years with an apple airport extreme that was working well, but, was outdated and no longer supported with firmware updates by Apple nor have adequate range in our house for Wi-Fi, I decided to look on Amazon for a newer and higher speed Wi-Fi six router. I tried a couple of other brands of wifi 6 routers, but, they just did not work out that well and lacked the desired GUI and setup screens I wanted. The TP Link AX 3000 router was my next choice to try and its GUI, setup and performance has been superb since set up. We use Xfinity\Comcast Internet service and our plan has a maximum of 450 Mbps download/12 mbps upload and right after setup, this router is seeing about 150 Mbps more speed using wireless in the house then AirPort Extreme could do even standing next to it. The AX3000 gives us our plan speed! I tried many varied settings for the airport extreme to see if I could get more speed out of Wi-Fi including trying different channels for 2.4 and 5 GHz, as well as a few changes for ipv4 and ipv6 settings and nothing I've tried could raise the numbers at all and at best, speeds were best about 250 mbps for Wi-Fi when within a room away from or even standing next to the router. The attached pic for a speed test for the AX3000 was done a room away from the AX3000 which is mounted high in a closet situated in the middle of the house (in a hallway) for best signal everywhere inside. The wifi speeds I am seeing now are close to what my wired ethernet speeds are and at the speed our plan is. That's impressive! What I'm seeing with the AX3000 for general Wi-Fi speeds are between 400-425 Mbps. I am also noticing a huge improvement in the Wi-Fi signal strength over-all. I can be at either end of my house or even out in the backyard now and still have plenty of signal and Internet speed to use. I could not do that with the airport extreme in which the wifi signal strength fell off much quicker by distance whether I was in the house, or in my backyard (where there was a weak signal to connect to, if I could connect at all from outdoors). We have a metal enclosed patio room and due to the metal walls, the Airport Extreme just could not reach there well out there from its closet/hallway location and internet speeds were reduced to around 200 or sometimes a lot lower mbps. I used a wifi extender out there as needed (with the Airport Extreme), but, as tested, the AX3000 has very adequate signal and speeds out there as well. Wifi speeds drop just a little out there using the AX3000 at around 375 mbps vs the 400+ mbps indoors and away from any metal. Impressive! No extender needed for my setup. A few reviewers noted, there's some special settings required for the AX3000 and some cable company ISPs. We have Comcast/Xfinity and I ended up having to mimic the MAC address of our old router to be able to finally connect. Having the ability to use default, clone or a unique MAC address on the AX3000 made the setup so much easier. Comcast does have an app where you can switch over to the new router basically where you will update the MAC address (to the Comcast server for your internet connection) for the new router so it works with your cable modem. I chose to work around that so I wouldn't have to use any app and that works better for me if I ever have to put the airport extreme temporarily back into use because I'll be using the same MAC address as I am now. Some of the routers I tried previously had no way to just put in their IP address and do the setup using a browser. These routers required an app to setup the router. The AX3000 lets you set up either directly at it's IP address using a browser or by using the free TP-Links "TETHER" app. One feature I really like in the advanced settings for the AX3000 is that you can choose either to have the IPV4 and IPV6 channels separate (using two separate WiFi network names for the 2.4 and 5 GhZ) or combine them into just one name and the router in that case will choose which one (2.4 or 5 GhZ) to connect to based on the signal quality, the device wifi capabilities and the location of your devices. My air airport extreme only allowed a separate 2.4 and 5 GHz Network to select from, but, with the AX3000 you can combine both into one (network name) and let the Router handle the best and fastest way to connect to each of your devices. That's nice for me because one name to connect you for Wi-Fi and your Network is all you need. It just simplifies things a little bit. The setup for the Guest network is similar. The AX3000 does have a very significant amount of adjustment and settings in the advanced mode, and I did change a couple things there, including the DNS servers that we normally use. Are use open DNS servers, using a primary and a secondary DNS and I put those into the router settings so that's where I'm connecting to (and then to Comcast). I have found better Internet speed overall when I'm using a public DNS rather than going directly to Comcast service. Your mileage may vary! I also use TunnelBear VPN here and the AX3000 has the option to basically always login and connect through the TunnelBear VPN servers which is really nice. Again because it's a much outdated model, my Apple Airport Extreme did not allow that but with the AX3000 I have the option of having a VPN on 100% using the router to connect to the VPN servers and not having to deal with turning it on it on each device using an app...very nice! Be advised that typically using a VPN will slow down your Internet connection a little because then you have a third-party access point in the loop that you're utilizing for your connection, but, for me, I have found that my VPN service does a superb job of keeping the Internet speed up substantially over a few others that I tried in the past which degraded speeds substantially. Given the large speed improvement using the AX3000, I'm fine with loosing some speed with a VPN. Also be aware the AX3000 has a full VPN setup that can b used to connect to your VPN through your router, rather then the need to install and use an app on each of your devices. VPNExress is supported in the AX3000 internally so if you have an active account with VPNExpress, you are good to go! My TunnelBear does not support router installation for it's app so I'm still using their app on each device to turn it on or off. Moving to a new router is always a bit of trial and error and tweaks to get it right and become familiar with a new GUI and protocol on the new router. The AX3000 took some time to tweak, but, once that's done, you going to be very happy with the maximum speed it will give you as well as the great signal coverage it has. Be sure to back up each time you change some settings. Its far easier to do that then try to remember all the changes you just made that did not work out. Backup and restore is the way to go. So far, so good and I'm very impressed with this new wifi 6 router. I'll update this review as required while this model is still current and available to buyers. 5 Stars all around!
