"Using my old router rt ax 5400 for gaming very good."
"Speeds are decent. We use it for COD/Rivals."
"AX5400 / AX6600 / AXE75 will likely give you better range and consistency because they have stronger radios and more streams, even if they’re –only– Wi-Fi 6/6E."

"There does seem to be a client limit at about 75-80 wifi devices whiche forced me to move iot devices to a separate wifi network."

"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. ... Unfortunately other than having the ability to enable a standard guest network my current router doesn't have either option."

"The gundam edition looks awesome but the stock black one is damn fugly."
Consistent-Baby5904 1.0it'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.
Far-Formal7433 1.0Do not buy the RT-Be92u for gaming as it is very bad. I have it and its just not good for gaming. Using my old router rt ax 5400 for gaming very good.
kester76a 1.0I've got the rt-82u and it's pretty solid. The gundam edition looks awesome but the stock black one is damn fugly. The tuf ax5400 is a better choice if the same price. https://www.asus.com/networking-iot-servers/wifi-routers/asus-gaming-routers/rt-ax82u-gundam-edition/ I use both as access points mostly unless I kill my main router.

Mousetachio 1.0So 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)
Odd_Example_1906 1.0Good, I did the same after seeing that the firewall operates as low, medium and high.
pakeco 1.0I have an asus rt-ax86 pro as my main router and a rt-ax5400 tuf as my airmesh. I've had it for a year without any problems. If I can help you with anything
I have the same RT-AX86U Pro and an Aimesh (Asus 5400). And I'm not planning on changing them for now.
RaccoonInASuit1 1.0I 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.
ShaneIyer 1.0Well 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.
tamudude 1.0I use the Asus RT-AX82U and it works great. It is currently available for $91.86 on Amazon [https://www.amazon.com/dp/B08BJJ3RGW](https://www.amazon.com/dp/B08BJJ3RGW)
Wide_Wrongdoer_9901 1.0Thanks guys, ended up ordering a ASUS TUF AX5400, should hopefully be much better than the hub 3.
I got the unifi access point since it's the only good company I know that makes aps, and I had really bad signal at the top floor. I did order a ASUS TUF AX5400 router tho, which router did you have which was problematic? Unifi router seem a bit expensive, expecially since my Internet speed is topped at 375mbps and like 40mbps upload, so I would never use the full power of that anyways, and the Asus router was only £50
