ASUS - RT-AX5400

it's trash, very buggy as of May 2025. cannot believe how horrible of a product it is. i ended up returning mine and going back to the legacy ASUS wifi 6 one. i'll wait a couple more years for it to mature.

So i got the 1800 and downstairs I was getting 800mbps and upstairs was getting 50. I then bought this one and am getting 800 upstairs [Link to Asus 5400](https://www.amazon.com/ASUS-RT-AX5400-Extendable-AiProtection-AiMesh-Compatible/dp/B0C1J5DYF6/ref=sr_1_1?crid=3VGCJEL60OM56&dib=eyJ2IjoiMSJ9.gm8NuFMJDV4LL0duevvYgE8LZX8Pg1eRmox_OaDi5GUbRr9RZ_Hqpmfao2hWdonfobjRD-XvTCI77h852JEZF3MwQ1H8lQ_aHagI0x9fZFxQNwyJoAC8IkKuzfo5F6hwRCAbyDQCItQb9kBXVsUjH2k-PhujC0A-m2BXOxG2uEUQcFIkd4FvHAbkMWqWiPCtPtMQjM69JfE4ORXIn1BKOYjqF59TXqfwpBcfgw4r8II.JS6PpEV8HruvM2rVCrlyp6R0ETjIoZUBG2aM_qWukug&dib_tag=se&keywords=asus+5400&qid=1748460106&sprefix=asus+5400%2Caps%2C129&sr=8-1)

I currently have an Asus RT-AX5400 router for my house. It works great, but doesn't have any features to subnet the network which I'm looking to do to be able to isolate a few servers I have from the rest of my devices. I'm wondering what your recommendations are for a good router with more features, mainly the ability to subnet. This would be the only router and AP in my house so it would need to have a decent wifi range.

It is overkill! Certainly is future-proof though, LOL! Even the RT-ax5400 would serve you well for ¼ the price.

I have the same RT-AX86U Pro and an Aimesh (Asus 5400). And I'm not planning on changing them for now.

Well it depends on what exactly you’re trying to optimize. I did a full reset of my TUF AX5400 and set up everything from scratch to fix any WiFi issues I had, especially WiFi calling. That said, I have about 10-14 devices online at any time at home and once I did this reset, all the issues I had were fixed. Unless you need multi gigabit transfers within the network or have a multi gig connection, it doesn’t make sense to change the router, especially when the devices and Internet can’t make use of it. If you do need to upgrade, get one with a better CPU rather than looking at feature list.

I have 2 x ASUS GT AX-6000 picked up from Amazon for $399ea. This replaced the 1 x TUF AX3000 and 2 x TUF AX5400 I previously had. My advice would be: Get a wifi router with high CPU performance Dual band or triband router At least 1GB system memory Inbuilt security Mesh expandability Reason for this is to handle the numerous amounts of wireless devices there area these days. Asus are the benchmark for wifi routers in today's market. Their software is hands down the best as well. I wouldn't worry too much about wifi 7 etc as no device barely support it. Hell we have just began to 90% utilise WiFi6. I have a 1000/50 connection at home with NAS and Cat6a wiring. I can tell you WiFi6 is plenty unless you are the 1% who require ultra uber fast wifi to download 10TB of stuff a week.

I've had zero problems with M1 for many years. Only went down once, and that was for scheduled maintenance in the middle of the night. Also, it's not just your internet plan that could be the cause of any issues. If your router isn't good enough, or is in a terrible position, or is overheating, or the bomb shelter is between your laptop and the router, you are gonna have issues no matter what plan you have. I have a standard 1Gbps plan but an Asus gaming router with ethernet cables going to the 3 heaviest users in the home – PS5, living TV and bedroom TV. I also set up a second router using Asus AImesh to provide wifi signal to one of the further corners of the house.

I've been using AiMesh since the beginning, and it was rocky at first, but now I'm currently quite happy with it. One solid main router and two APs outside. What unifi did you get to replace your setup and do you think it was worth the cost?

Asus AiMesh - Yea TP-Link Deco - Yes TP-Link Easy Mesh - Not sure

I use Asus routers in my Ai mesh network and it gives me complete control over everything and I've loved it. I use that coupled with family link from Google and I feel like I've done my job as a parent blocking as much bullshit as I can for my kids.  But don't worry, their friends who's parents don't care about a single thing they consume will come along and ruin your hard work. Or your kids will be kids and find loop holes, which they always do. But you still tried. 

Asus AiMesh can be configured without an app and uses local credentials for management.

I went from DD-WRT for years to ASUS AiMesh and have been on Unifi equipment for a good four years now. I never have any issues with roaming (3600+ home) and I can fine tune whenever necessary (rare). I love the Unifi and don't plan on moving away any time soon. If you want peace of mind, I definitely also recommend Unifi.

As has been said, plug in everything you can. For a basic option, the Asus routers with AiMesh are a pretty simple solution. Start with one on the second floor centrally located and see if you need more. Use inSSIDer to see how your signal strength is as what kind of interference you have and set settings accordingly. If you’re not reaching all corners, add another compatible Asus and put them on floors 1 and 3 (both wired connection to WAN jack)

Avoid tp-link and any other CCP networking equipment. Don't intentionally put stuff with backdoors in them just to save a few bucks. Unifi is great but it's expensive and you really should use it wired. If you're just looking for plug and play mesh Asus has good offerings. Their AI mesh system works well
