hAP ax3 behind Internet Router with DHCP, not working as desired

RouterOS Beginner Basics
1

Hello,

just bought a hAP ax3 but I can’t get the configuration right.

  1. The first Router is an AVM Fritzbox with DHCP enabled and it´s own IP is 192.168.0.1 / 255.255.255.0
  2. Then comes the hAP ax3
  3. The WiFi Clients connect to the hAP ax3

Internet is working “Out of the Box” but

hAP ax3 get´s an automatic IP from the AVM (192.168.0.63) but it also spans a new DHCP server with an own network area.
From the view of the WiFi client my gateway is 192.168.88.1 and the clients´s ip is 192.168.88.153

My desired configuration is that the gateway for the WiFi clients is 192.168.0.1 (the AVM router) and the ip should also be obtained from the AVM.
I don´t want to use two separate network areas.

What needs to be changed with Winbox64 to get this done?

Flat network or do you have vlans for different SSIDS, ( home, guest, iot, media, etc…)

For a network without vlans…

OK, you want everything on the one subnet. In which case, you need to use the hAP ax3 in bridge mode rather than router mode. Router mode connects between different subnets …

This video helped me enormously with a similar setup.https://www.youtube.com/watch?v=s5am82iw2vM in explaining bridges in the context of Mikrotik. This comes from The Network Berg who has made loads of videos covering Mikrotik and general router issues.

Another useful video is https://www.youtube.com/watch?v=gcwbhncwPug if you want to setup a guest wifi. This one comes from Cat5TV and is part of a short series on Mikrotik routers. There is another one in the series which gives an intro to firewalling.
