My main router is an Asus, but it did not have quite enough range to provide a strong wifi signal to the far corners of our house. I bought this second Asus router as a wifi extender. Asus has its own proprietary extender software called AIMesh. It works great - absolutely seamless in actual use. Very easy to setup. Every corner of the house now gets great signal strength using two Asus routers and AIMesh. No need to tell your many devices which router to use - they all just connect without any special instructions or routines. You can also select a software option called “Optimization” which appears to automatically analyze your network signal strengths and devices, and then adjusts the network for optimal signal strength and speed. The network was already fast, ... MoreMy main router is an Asus, but it did not have quite enough range to provide a strong wifi signal to the far corners of our house.

Also, if you are not doing heavy gaming, you can use the Asus app to instead optimize your network for video streaming or web surfing - that improves performance too. Of course, gamers will prefer the other setting. Really pleased with this purchase and with the Asus app which shows your entire network and all the devices connected to it. And the programmers finally realized that most of us are not programmers - and they made this app pretty easy to use.

I've been using the Asus RT-1900AC for a few years now but wanted to extend coverage for another IP security cam attached to the garage. Signals were intermittent at best so I installed the RT-AX55 at the back of the house using Asus' AIMesh feature which works in a master/slave whereas the slave inherits all of the features of the master. Ideally, I should have used the newer router as the master and the "old" as the slave. But it was a long day of tinkering and the network is functioning 100% with a stronger signal from activity at the back of the house . . . and all the way to the garage. Good product and features!

Decided my older Asus router was overdue for an upgrade (I've had it for many years, with a generally positive experience), and went with this one.Terrible mistake. A little over a month after setting it up, I woke up one day to find it non-functioning, wireless or wired. Even with hard reboots, the router would only work for a few minutes before crashing again. I assumed it was the internet at first.Logged into the router during its few minutes of hard reboot functioning via ethernet, once I was certain my actual internet was fine, and found all manner of errors in the router logs from the day it failed.

I was originally using the basic modem/router i got with att uverse fiber. This was fine enough for most things. I needed more parental controls of my household electronics and was looking for a solution.glad i went with this one since it wasnt overkill and could still take full advantage of my 1000mbps from att and it had very nice features built into the app. I can now control wifi hours of my kids devices so that they arent able to play online all evening. configuring the att router/modem to be passthrough was a little complicated but i was able to figure it out. It paired easily with my asus rp ac55 extender. i have about 2200sqft and use to have trouble reaching the 2 farthest rooms but not anymore. i did have to do some manual port forwarding on this router ...

Att speed test was about 500mbps, test on this one about an hour later was 700+ mbps.
I purchased the router as my previous router was not functioning. I found the ASUS-RT-AX55 very easy to connect and set-up. I have great coverage in my home now. I also get great download and upload speeds. I made sure to place the router in a central location in my home. I continue to purchase ASUS products as I find them to be good quality and price fairly compared to a lot of other products on the market. I like the fact the router configuration pages are very customizable and it came with built in security software.Please note I'm receiving a warranty extension from ASUS for my feedback.
I purchased the Asus AX1800 router to use in a small biz office environment. This router has proven to be both dependable and offers fast speeds for all users in our environment. As with any router, make sure to update the firmware immediately for the latest updates and features. I setup this router entirely with the free Asus app, and the administrative features are intuitive enough for new users but offer features for advanced network control. As a side note, the difference between the AX1800 and AX1800S is the processor. This model, the AX1800 has a superior Broadcom quad core processor as compared to the dual core processor in the lower priced AX1800S. Those who do a lot of streaming, gaming and/or have many clients connected to their network will be better ... MoreI purchased the Asus AX1800 router to use in a small biz office environment.

I most certainly would recommend this Asus AX1800 router to others.
I love my Asus routers. I has Linksys and Netgear before. This router replaced a 6 year old unit that started to have session drops. Operation of the AX55 has been flawless: easy to setup and fast. It just works. However, it lacks the parental control and security features my old router had. If you need to monitor kids, get an Asus with AiProtect Pro. The AiProtect Classic in the AX55 is stripped down. I added an AX68 as my primary and am using the AX55 as a mesh node so I now have strong WiFi-6 coverage all over the house.
I've gone through a lot of routers in my lifetime, and watched them become easier and easier to manage. This one ranks towards the top, with a few caveats.Pros:- Sleek, modern look.- Comes with both a mobile app and a browser-based setup page.- Includes utilities like a built-in Ookla speed test to help track down bottlenecks in your network- Plug-n-play on simpler networks- Wall- or desk- mountable- Fast!Cons:- The antennae seem fragile and are not replaceable- There doesn't seem to be a separate activity light for each port- Not all features are available through the app, and the documentation doesn't explain what can be found where. For example, I could find no place in the app to change the default IP address, and in fact MOST of the ...

I bought this because I have an Asus RT-AC86U with which I was quite happy, but it was getting a bit unreliable, as older routers do; it was now too unreliable for my stuck-at-home family who hold strong feelings about the reliability of their network connection.My ISP feed is 100Mbps/10Mbps so I looked at dual band mesh routers, as tri-band would be overkill, and I had decided it was time to move from a single router to a mesh network. I decided the Asus Aimesh would give me the same performance as the Netgear dual band mesh I would be likely to buy, with less cost now as I'm already invested in the Asus system. The Asus solution is feature rich also, probably intimidatingly so if you don't have experience with routers. You can just ignore the settings you don't ...

The Asus solution is feature rich also, probably intimidatingly so if you don't have experience with routers. You can just ignore the settings you don't understand. Anyway, the rich set of features was a plus for me when compared to the less configurable Netgear mesh network I considered. The RT-AX55 was the cheapest WiFi6 ASUS router I could find with good wireless features, and 1800 Mbps is plenty for my ISP feed. I found the RT-AX55 on sale at Best Buy. For the sale price I paid for a brand name router, with a very up to date feature set, I don't expect better value than this.I installed the RT-AX55 as the new router and moved the RT-AC86U to become a wireless Aimesh node. RT-AX55 setup and Aimesh setup were easy. The RT-AX55 has rather limited RAM. I usually see 3% CPU usage and 66% RAM usage with 30 or so wireless clients, and a few wired clients, so capacity is good in spite of the amount of RAM provided. This is in an Aimesh network so I don't know if these metrics would hold for a standalone router application.The combination of these two routers in the Aimesh has been reliable in the couple of weeks I've used it. I'll stay in the Asus Aimesh ecosystem and will consider a second RT-AX55 unit when the RT-AC86U needs to be retired. (I considered Easymesh rather than Aimest but I suspect Easymesh is an open standard with little participation beyond one company, so I consider it practically a proprietary mesh standard at this point)Supposedly you can set up to four guest networks on Aimesh (or this router) but I didn't have success beyond one guest network, and wasn't inclined to invest more time in experimentation.Compared to the range of the mighty RT-AC86U, the RT-AX55 broadcast range is much less impressive, so that's why the RT-AX55 gets four stars instead of five. Other than range, I'm quite pleased with it. The RT-AX55 by itself probably would be fine for many 2000-2500 sq. foot two-story houses if positioned closer to the centre of the house.Two RX-AX55 units (on sale) in an Aimesh is reasonably priced as a feature rich WiFi6 mesh alternative, if you have modest ISP bandwidth as I do. Networking the two units together with Ethernet would be even better, and probably serve well for a 250-500 Mbps ISP feed when so connected.
Purchased this to upgrade to wifi6. It works well, but I am not completely happy with the setup webpage on this device. Probably very easy for a non-technical user to set up, but I am using this in a rather unconventional way. I am using it as a non-internet connected access point. The setup assumes you will be using the wizard, and the wizard forces you to coinnect the internat connection first. I had to call customer support because there was no obvious way to get around this that I could see. Customer support was ok, and eventually we worked out my problem. The answer was to go directly to "advanced" and bypass the setup wizard completely. That worked allowed me to configue it the way I wanted.
