how to create a stable multiple WDS

RouterOS Wireless Networking

Hello,

I want to create a private LAN with 3 radio (one RB 433, two RB 411).
All RB must be in bridge because I can’t introduce a level 3.
I have followed the indication referred by mikrotik documentation:

MODE A

  1. wlan1 of the RB433:
    -bridge mode
    -WDS static
    -WDS1 interface with wlan1 as master and wlan1 mac address of the first RB411
    -WDS2 interface with wlan1 as master and wlan1 mac address of the second RB411

  2. wlan1 of the first RB411:
    -bridge mode
    -WDS static
    -WDS1 interface with wlan1 as master and wlan1 mac address of the RB433

  3. wlan1 of the second RB411:
    -bridge mode
    -WDS static
    -WDS1 interface with wlan1 as master and wlan1 mac address of the RB433

The problem is that in this mode only one link at time is up (the other is down).
But when I change the wlan1 mode of the RB433 FROM “bridge” TO “ap bridge”, both the links are up at the same time.
Unfortunately when the traffic between the two RB 411 is over 4 Mbit/s, one of the two WDS becomes down and it doesn’t become up any more (I must reboot the RB 433 in this case).

Is there another configuration more stable than this one?

What do you think about RB 433 in WDS “static mesh” and the two RB 411 as station wds ?

thanks

But when I change the wlan1 mode of the RB433 FROM “bridge” TO “ap bridge”, both the links are up at the same time.

That’s correct and it’s the most important difference between “bridge” and “ap bridge” modes (in bridge mode only one client connection per AP is allowed).

You should consider that as well : due to the fact you are using one antenna only on your RB433, bandwidth to the second hop on your configuration is half of the maximun bandwidth allowed (WDS implementation limit).
So a troughput overload could cause some problems as the one you reported.

On RB433 use AP mode and static wds, on RB411s use station-wds mode.
