I am using Asus TUF AX5400 currently in a 900sqft condo. So far the Wifi coverange is acceptable. The WiFi and Internet speed somehow unstable and I schedule to reboot it every night. Another problem is after I disable the Surfshark VPN connection in the router. The streaming quality constant at 480p until I reboot the router.

I have few requirements for a wireless router, and wonder mikrotik hap ax3 fit into it or not.

1. Docker services, eg: HomeAssistant/Uptime
2. VPN services to Surfshark
3. Decent and stable wifi coverage for whole house
4. Split the 2.4G/5G SSID due to some smart home devices cannot connect to 5Ghz network

1. if i am not wrong,u need a pendrive / external usb ssd/hdd drive for docker related services
2. With Wireguard protocol yes,but the speed might not be able to hit the max speed with your internet plan. (And while utilize high speed with vpn,your router cpu usage will also be high due to vpn data encryption)
3. Use your current Asus TUF AX5400 as Wifi AP,the processing power stress will be lower for both device. (Or you can place both on different place with connected ethernet connection)
4. Yes,routeros does support this kind of wifi setup.

2. I don't need max speed, as long as it able to stream with decent quality. It's acting weird on current router, where it can stream fine with Surfshark Wireguard VPN, but as soon as I disconnect the VPN, the streaming quality dropped to 480p, until I restart the router.
3. I was thinking to make current Asus TUF AX5400 as access point, but I also want to keep minimal devices. That's why I am considering hap ax3 instead of RB5009UG. It's a small condo and I don't have ethernet connection else where. I have around 30 devices connected via WiFi, and half of them are smart home devices. Thus, WiFi coverage and stability is the utmost important requirement.

I have RB5009 as main router (router, capsman, vpn) and ax3 (containers & 5Ghz wifi.) and ax2 (2.4 & 5Ghz wifi) as APs  Not sure how a single ax3 would fare if everything is on it.

1. Docker so far working quite reliably. I have AdGuard Home, UptimeKuma and Lego on the ax3. Using a USB3 thumb drive for container storage.
2. Main RB5009 router set for NordVPN, VPN Unlimited and Zerotier. Seldom use the VPN though so can't say much about it.
3. I use ax3 and ax2 for 2-storey house. Coverage pretty good. 2.4Ghz active only on the ax2 for IOT and legacy devices. ax3 is 5Ghz only, covers back of the house (up & downstairs). ax2 covers the front (up & down)
4. Multiple SSIDs no problem. Can set to your heart's content.

Before I got the ax3 & 2, I used Deco M9 Plus and then X20. Also tried TM's DLink for a week or 2 which was pretty good. Don't like and have never used Asus for many years already.

Updated to macOS 15.0 on 2 x MacBook Air and 1 x Mac mini and unable to connect to Wifi. iPhones, iPads & HomePods updated to 18.0 are OK.

APs are hAP ax2 and hAP ax3 capsman managed by RB5009.

Will troubleshoot tomorrow.

I've deployed mikrotik AP's to customers in the past, its often the apple devices that have issues connecting to the MT's.

What channels do you have the AP's setup on?

Updated to macOS 15.0 on 2 x MacBook Airs and 1 x Mac mini and all unable to connect to Wifi. iPhones, iPads & HomePods updated to 18.0 are OK.

APs are hAP ax2 and hAP ax3 capsman managed by RB5009. All on latest stable 7.15.3.

Will troubleshoot tomorrow.

Update:
• Turned off FT (Fast Transition) and the Macs connect again. No idea whose fault it is.
• The Macs had no problem connecting to neighbour's wifi. One is Skyworth and the other one, I think, is DLink.
