    Highly recommend! Easy to set up and use!

    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 route

    NOT made in China. Fast, excellent security.

    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 per

    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.

    Limited parental controls

    Relatively easy setup. However, I had to trade in my modem/router combo for a simple modem with my ISP to ensure that the kids couldn't connect to the old router and bypass the new parental controls.I didnt see any decrease in internet speeds. Parental controls and time management seems to work well. It's nice to be able to see and name every device that connects to your network, and to set different permissions for different devices. For example, you can set one child's bedtime for 8:00 p.m. and another child's for midnight, and their internet will cut off at whatever time you set. You can al

    Annoying firmware bugs

    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...Dec 8 22:05:40 kernel: ap_link_up(...), wdev(0) ← 2.4 GHz came up on channel 11Dec 8 22:05:42 kernel: New Sta:80:48:2c:53:be:dd ← first phone connected to 2.4 GHzDec 8 22:05:44 kernel: New Sta:2c:aa:8e:31

    So far so good for a basic value router.

    I've only used it for few days, but it's been stable and I've experienced no issues with this so far.It's good as a basic value router.It's got many features, but I'm only using 5G wireless, 5G guest wireless, and LAN port access.It's connected to an old cable modem and it's been working fine w/o any disconnections so far and I hope it stays that way for 3 months at least. Of course I'd hope that it works stable for many years, but I do really need it working without any problem for 3 months as I will not be near by it to checkout the issue if anything pops up.

    ASUS makes THE BEST routers HANDS DOWN 😋👍

    ASUS routers are hands down the best. Whenever I get a new router I always pick an ASUS and they have never let me down.Ease of setup - 10 ( Super Easy PnP setup + the optional advanced settings )Looks - 10 ( ASUS routers ALWAYS look great )Power - 10 ( Power supply is fine )Range - 10 ( GREAT RANGE and can be configured )They are well made and tinkerer-friendly / HIGH CONFIGURABILITY.Which is the most important thing on a router. You need to have full control over the network otherwise YOU ARE DOOMED to have a crappy network 😅LIKE the eero systems you cant even control the bands 🤭 throw 2k
