Love this router!
Style: 1.8 Gbps
The ASUS RT-AX1800S router is one of the best electronic purchases I've ever made. Easy setup, covers a long distance, and provides a great signal to anywhere from 9-16 devices. Very configurable too. Highly recommend.

You can verify everything written here is true with a quick google search. Talking to you, Amazon. While ASUS does source some production to China, ASUS is a Taiwanese company and the sticker on the router states “Made in Vietnam”. I’m inclined to believe that. The product origin on this page states “China” but I doubt, and hope, that’s not true. You may not think it matters, but it does more than you might know. Most consumers only care about speed and affordability when it comes to routers, but it should be security at the top of the list. All your data flows through your router, including personal and financial data. Security flaws in your network can also affect neighboring networks around you. If you buy a cheap router based on speed capability alone with security flaws built in, either intentionally or not, you’re basically paying to be hacked, or for your neighbors to be, or possibly unknowingly being a conduit for attacks on your entire country. It has happened in the past, it’s still happening, and will continue to happen. Most routers today are produced in China. Even companies based in the US produce there and it’s very hard to find one that’s not made there. The problem with routers made in China is that ultimately, businesses there are controlled by the CCP government, not the business owner. This allows their government to implement whatever they want in their exported tech and products. It’s why some of their tech companies like Huawei have been banned in numerous countries. Routers made in China from brands like Wavlink which are sold in big retail stores across the US have been found to contain hidden back doors and intentional security holes and vulnerabilities to malware like Mirai. Basically open doors for hackers. Some of these back doors have been used in the past to launch cyber attacks (Mirai botnet) on the US which caused major network outages, as well as in other countries. From a cybersecurity perspective, these look a lot like “trial runs” to me. But speculation and paranoia aside, why take the chance on inviting that kind of tech into your home? It wasn’t an isolated, one time event when these back doors were discovered, and it was with various routers and companies out of China. Again, all this is verifiable with the slightest amount of research using credible sources. I have tried some routers made in China. I could tell they had horrible security just by using the app, or during setup. One was capable of remote access, yet the option to turn it on or off was non existent. It didn’t even ask during set up and the option was nowhere in the app. Remote access should always be turned off, unless you need to access your router from outside your home, which is rarely needed for the average user. If it’s on, it’s just an unnecessary access point open for hackers to attempt access. It might have been possible to check by connecting directly to it using the Web UI, but instead I just returned it and went on the hunt for non-Chinese routers. It took a lot of research since there aren’t many, but finally landed on this one. I am much, much happier with this ASUS router and it seems very security focused! There are numerous security options available in the app, and also asks you about remote access during set up. It has AI Protection by Trend Micro built in (included free of charge) which constantly monitors your network for viruses and intrusions and even blocks harmful websites. You can also monitor all connections and traffic through the app. There are even additional apps you can download for more functionalities. As for speed, WiFi 6 is awesome. This thing is lightning fast to my previous ISP provided router and much more stable. If you’re not familiar with WiFi 6, it’s not really a speed booster. It provides a more stable connection though, even in very signal-congested areas such as apartments or offices where there’s numerous routers and networks overlapping and causing interference. This more stable connection will often times yield higher speeds. Your PC and various hardware must be WiFi 6 capable to utilize it, but there are cheap and affordable USB adapters available to enable it on your PC if it’s not already capable. Aside from that, the 5GHz signal is stable and fast, even without WiFi 6. 2.4GHz is not bad at all either. There are options in the app to monitor what’s connected at all times and you can even limit bandwidth to certain devices, or ban them from connecting completely if you want to streamline your connections. There are a lot more features to this router, which are easily accessed from the app which appears extremely robust compared to the anemic apps I used with the Chinese routers. Those seemed like toys compared to this. I haven’t tried Ai Mesh, but it is yet another useful capability of this router. Completely happy with this router based on speed, stability, capabilities, and most of all, security! ... show more

Highly recommend! Easy to set up and use!
Style: 1.8 Gbps
Granted, I just got this router in so I can't speak too much on the reliability yet. However, I will say the looks of it is really nice. It's smaller than my prior router (which I will get into in a bit) and the aesthetics is rather nice. Looks like a futuristic device. Setup was easy especially through the ASUS app. I didn't try logging in with a device plugged in until after it was set up, but again, super easy set up that even a beginner/novice can do. Devices connect wirelessly without a problem and I can't wait to test it out throughout the house. What attracted this particular ASUS router to me was the very fact that it said "subscription free." This was attractive because my prior router (which I don't think I'd be allowed to name) stopped working after accidentally unplugging it. I couldn't access it to re-setup my wireless network even after rebooting it and later, trying to reset to factory settings. I called their (the prior router manufacturer) support number for help and they wouldn't even bother unless they charged me $180 - $250 for something they called a "firewall security renewal." This wasn't their "bit defender"/anti-virus thing they have separately. No, they were wanting to charge me for something ridiculous before they would help me. At that point, I just said "Forget it. I'm not paying that! And I'm never buying any of your routers again if that's the kind of business/scheme you're running." They didn't seem to care. I came upon this ASUS router on Amazon. Again, the "subscription free" part was very attractive to say the least. The GUI was by far more pleasing in aesthetics to look at than the other one, and so far I'm happy overall with this new router. It seems to work better and faster than my prior router (which is old, I know) so that should be a given. If you're looking for a hassle free router with hassle free set up? This might be your go-to. ... show more

Decent and cheap
Style: 1.8 Gbps
Perfect for an apartment I would say, however in our house I expected it to be a bit more of an upgrade than it was from our old ASUS WiFi 5(802.11ac) router. Wall penetration seems almost as bad on 5GHz, probably a smidge better. Of course that is partly the nature of the 5GHz spectrum allotted for WiFi, it's great for speed, not wall penetration, but also can come down to the gain and quality of the antennas. Not as good as a TP-Link WiFi 7 router I had temporarily on loan that only costs only a little bit more(~$10-20), albeit a much more simplistic interface(less options and control). The firmware is as usual for ASUS, if you've used it before, you probably know what you're getting. It gives you plenty of control and features, although feature set may depend on the router. Of course you can also use custom firmware like DDWRT and the like. I also find the lighting choice an odd one, making all the lights face downward so you can't even see what they indicate, especially if the surface they shine on doesn't show the light well. At the end of the day it's a solid choice for the money, albeit a bit dated nearing 5 years old and because of that no support for WiFi 7, let alone WiFi 6E. If it's all you can afford, have at it you're not going to be missing too much, but networking hardware tends to last a long time, so having something current can be nice if it will last you 5-10 years easily. ... show more

Simple to set up and works great

I have an existing ASUS 8800 router and wanted to extend the WIFI range, plus allowing for a few hard wired ethernet cables. This fit the bill perfectly. Using ASUS AIMesh, I was able to simply turn the AX-1800S on, place it near my ASUS 8800 router, search for AIMesh devices and add it in. It connects seamlessly and uses all my settings. 10 minute setup. ... show more

Annoying firmware bugs
Style: 1.8 Gbps
This router has a firmware bug that Azus refuses to fix for iterations now where the router sees too many connections and drops signal. It has caused me a headacke for weeks until I nailed the firmware bug and had to disable Wifi 6 in the mean time. Do not get buy this or you will struggle with multiple devices connected. It's junk. rc_service: httpd 953:notify_rc reboot ← you pressed reboot ...

That’s why we see the SSID for 10-60 seconds and then it disappears forever until the next reboot. That is not a hardware or driver crash. It is the firmware deciding to disable the 2.4 GHz radio right after boot.The real culprit (100 % confirmed on this exact model/firmware)This is a known bug in ASUSWRT 386_69155 (and several earlier 386 builds) on all MT7915-based routers (RT-AX1800S, RT-AX55, RT-AX56U, etc.) when both of these conditions are true: Smart Connect is enabled (single SSID for 2.4 + 5 GHz) **802.11ax / Wi-Fi 6 mode is enabled on 2.4 GHz Disabled both kind of work around the problem but now I dont have wifi 6 mode. It's junk and ASUS needs to get their **** together. ... show more

Excellent affordable replacement for rental ISP device
Style: 1.8 Gbps
I'm just started year 2 of a 2 year promotional plan with my ISP. 500 Mbps for 49.99. That included the modem and a WiFi6 router. So, my last statement the payment went up, even though I'm "locked in" to a promotional price. That did not sit well, so I bought this ASUS router, and returned the ISP one. It lowered my bill beginning the next cycle, and the device is a lot more flexible, and not monitored by anyone but me. As for the Router, I've had a number of ASUS products over the years, and at least two other routers. I wanted to maintain the WiFi6 speed of the ISP router, so I needed an upgrade from the routers I already own. Setup was super easy. I followed the directions and they were accurate about connecting the device, powering things on, accessing the router via IP address, updating the firmware and the setup of the network security. It read the ISP modem specs and set things up automatically, which is easier than my previous routers. I created the same SSID name and password, and all my IOT devices, Roku's, phones and computers connected right away. Speed has been fully or slightly above the rating of my plan, and the signal range is better than the ISP router, which had two internal antennas. I have had the ASUS for 31 days now. It is connected to a UPS for power consistency, and I have not had to change anything or reset the device even once. Very good. If you are looking for an affordable, mesh capable WiFi6 router with built in security and an extensive but easy to grasp settings menu, you could do far worse than this one. Definitely one I would recommend. ... show more

Excellent budget router

The router I received on December 1,2025 had its firmware updated on November 14,2025 . The web interface records this information. I called the manufacturer and provided the serial number only to learn the warranty started on November 4,2025. This router had shrink wrap on it so it appeared to be new. The Asus routers are the best on the market and this router is no different. I’ve used Cisco and Netgear routers and they don’t offer the features this router offers. I plan to limit my purchases on here because used stock reaches customers because of either marketplace sellers sending in used stock that gets mixed with new stock from manufacturers or it was a return that was re wrapped as new. This router has decent range but offers all the features of more expensive routers. I get excellent speeds when I’m in range. I’m using this as a node for a AiMesh setup. I’m glad nothing is wrong with it. I don’t like returning anything even when I’m not at fault because I look like a bad customer. The marketplace needs shut down permanently ... show more
