How to have hAP AC Lite use router's subnet

RouterOS Beginner Basics
1

Help, please, and thanks in advance.

I’m used to having WiFi access points be dumb switches. They get a management IP from the router’s DHCP and all the wireless clients get DHCP and other services from the router just like the wired clients do. The hAP uses RouterOS so it has it’s own firewall/router/subnet/dhcp. Wireless devices get DHCP from the hAP on that subnet.

Issues:
– When I connect the hAP to the router using it’s Internet port the wireless devices connecting through the hAP get to the Internet just fine but can’t see the wired devices connected through the router. For instance, the Sonos wireless speaker can’t access the music on the wired file server, and the wired PC can’t access the Sonos. I have had the hAP connected to the dumb 8 port switch and direct
to the MikroTik router.

– When I connect the hAP to the router using one of the switch ports wireless devices can access the wired devices but can’t access the Internet, and the hAP can’t be managed.

How do I configure the hAP to be a dumb switch?

Wiring “diagram”:
Internet ↔ MikroTik RB750Gr2 router 192.168.1.1
MikroTik RB750Gr2 router ↔ dumb 8-port gigabit switch
dumb 8-port gigabit switch ↔ wired devices
MikroTik RB750Gr2 router ↔ hAP AC Lite 192.168.88.1
hAP AC Lite ↔ wireless devices on both bands.

To create a “dumb” AP/switch (from a reset to defaults Hap ac Lite):

1.- Make all ether interfaces slaves of ether1.
2.- Add a bridge; add ether1 and wlan1 as its ports.
3.- Add a DHCP client on top of that bridge (for management purposes)
4.- Plug any of the Hap AC ports to the main “router”
5.- Setup wireless AP portion.

That’s it. The logic behind it: all interfaces in same L2 segment, along with the "main " router (750Gr2), which will be the one handing out DHCP addresses, routing, masquerading, etc

Bit of an old topic to bump, but this solved my problem completely.
I’m no stranger to slightly more complex networking equipment, but this was like being dropped in at the deep end without a float :stuck_out_tongue: All the options and no handholding…

I was trying to follow various guides and getting nowhere. Your guide specifying in general what to do, not specific instructions made it click.

Thank you very much, i’ve got it working and i feel i learnt a lot too :smiley:
