Please i need some help with this configuration:

I have:

6 AP -> 3 of them with RB532 and 2 R52 (2 antennas, one omni and other flat)
the other 3 with RB532+RB502 and 3 R52 (3 antennas, one omni and 2 flat)

i want to make something like this:

ether1 -> wlan1
ether1 -> wlan2
ether1 -> wlan3
and then
wlan1 -> wlan4
wlan2 -> wlan5

Only one of my AP will be connect to a ISP the ethernet one.

Is this configuration possible?
Can I use wds? How?

Can anyone help me?

P.S:I can try to explain better

Sofia,
If you make a Croqui will be better to explain.

it would be good to look at mikrotik WIKI and read what topics about wireless there.

then you will have more understandng about what is posible and what you can achieve.

Good luck!
