Works very well.
I’ve been very happy with this setup since I used it to replace my older ASUS router that I was using and had for over 5 years. This combo has allowed me to have very good to excellent wi-fi reception throughout our 225+ year old house from second floor to basement. The Wi-Fi 6 can be a bit finicky at times.

Simply a bad product.
Do not purchase these routers.They were nothing but problems from the beginning.Mesh wasn’t stable. Was alway losing connection.WiFi constantly dropping, slow speeds, and daily drops in WiFiIn the end of my using this router. It would not maintain a intenet connection， only a factory reset seemed to correct it. But then the WiFi stability got worse.These modems are horrible.

Finally I get my ISP speed all 3 floors-UPDATED!!
This ET9 is very impressive compared to Linksys MR9000 + Linksys Extender (3rd floor).My setup:Large home, 3 floors, router in corner of basement and 2nd node 3rd floor. Using 6 Ghz as front/backhaul wireless.The 2 nodes are approx. 50-60 feet apart going through wood/ceramic floors, and standard walls. 2nd node has 2 bars vs the full 3, to middle of house on 3rd floor.I now get 300 Mbs anywhere in the home which is much faster the 60-90 Mbs I was getting on 3rd floor with Linksys Extender and front of house 3rd floor was getting 10-20 Mbs.What I didn’t like at first is that it used the 2.4 Ghz bands even if I was close or far from the router (node 1). So here I thought its like other people claiming it doesn’t go higher than 150 Mbs…..I turned off the 2.4 Ghz band completely and BINGO….got my ISP speed.So my 4 star is based on this. I would have expected the router figure out which is the faster band and then downgrade to 2.4 it couldn’t connect to 5 or 6 Ghz. Test here was with my iphone 13. Other thing was I could not change my subnet to their default without using a standard web browser on a laptop.The firmware both devices upgraded just fine.The inital app setup on iOS didn’t even list the ET9 router. I found this odd. Why would it list all the other new ones but not ET9. After selecting “other” then eventually it finds ET9 and shows the pretty picture of the router. Scary at first but you need patience with this for sure. Not recommended for your average non-IT person. This router has some super nice features and I still haven’t played with all settings or even optimized it yet. Why brake something when its pushed my ISP speed and have zero issues, so far.So if you are like me that had a ~$150 router and kids/wife always complaining, get this Mesh. Like I said, very powerful antenna’s in this little box.UPDATE: So the past 2 1/2 weeks I’ve been trying to fix this ET9 system as its dropping packets and has timeouts during ping sessions to Google for example. I’ve traded over 22 emails with Asus support, and about 5-8 different people saying, “Were sorry…blah blah…” and the problem is not fixed yet. I’m probably out of my return policy to Amazon now and stuck with 2 $600 bricks for door stops. They have no clue what the problem is. Smart Connect is crap, they asked I don’t use it. Why not? I used it in my Linksys $100 router and no issues. Here we need to premium costs and told don’t use that setting. Then why advertise it? If you have XBOX – same issues. It seems when you have a constant need for a connection it drops 10-15 seconds. There are like 30 parameters on the Wifi advanced page and you’d think they would advise on that. Maybe 1 of them are wrong. Worked fine for about 3 days, then…BANG!!! dopped connections…no changes, no power outages…Hate to say it, I think I need to go back to Linksys where although firmware is crap, at least their wifi technology is much better than Asus from my perspective.

Simple to configure and very reliable – 3 routers on 2 Wi-Fi networks
I installed 2 of these routers together as one mesh network and a third to create another mesh network with an ET12 Pro.Setup was trivial using the Asus app. For the pair I just followed the instructions inside the box. ~ 20 minutes later a network was in production. The second was simple using the same process.Both networks have been reliable for ~ 3 months now, and by reliable, I mean no downtime other than automatic firmware updates. The routers keep the mesh networks intact and clients happy. So I am happy.Great technology and ASUS support was contacted about firmware updates, one time – I contacted them on my first attempt and my question was answered. I’ve had ASUS routers, motherboards, gfx cards exclusively for over a decade now, and they are responsive and responsible. And the technology is bleeding edge, so one might expect a bump or two on occasion – but it’s rare and you will pay more for it.

Great unit. Was tricky to mesh with existing system

I am not sure if this is a mistake by Asus or Amazon. I ordered the Asus ET9 (2-pkg) from Amazon Warehouse. The items came in the Asus ET9 package w/ the label (sticker at bottom) indicated that it is an Asus ET9. Upon installation, I noticed that Asus app indicated that it is the Asus XT9 for the Device Name. Even the MAC IDs did not match. I am returning this item.
