After I upgraded couple of my ruterboards to RouterOS 3.2 all my links on Atheros 5213 stopped working. Links on Atheros 5413 works fine. I use WDS (APBridge-WDSSlave).
The only solution is to downgrade to OS 2.x which doesn’t go smoothly either. After downgrading all wireless cards are disabled and resetted so I need to perform config restore.
Anyway something’s wrong with this new OS.
What configuration you have. And what you mean with ‘stopped working’, we need more information?
After upgrade it just disconnects and can’t connect until I downgrade.

try setting the rate-set to default.

Is this happening on the WDS-slave router or on the Main AP?
This is happening after Main AP Upgrade.
But I have another link which behaves differnetly.
In that case Main AP has Atheros 5413 but WDS Slave (RB 133) has Atheros 5312. When I upgrade WDS Slave it connects to AP but there’s no WDS link and after couple of seconds RB disconnets my session (telnet, winbox or ssh). I need to reboot to connect againg to RB but after a while it happens again. And so on until I downgrade to 2.x.
There is another strange thing on OS 3.x. On RB with multiple wirless cards, when I disable and enable one of the card, all other links disconnects and then reconnects after couple of seconds.
After further investigation it turned out it’s a RB133 problem, not Atheros. I tested it on couple of RB133s. Whatever wireless card is installed after upgrade of RB133 to 3.x WDS links stop working. Normal AP-Station mode works OK but after adding WDS problems begin (ICMP loss, terminal disconnecting etc.) making MT unstable.
Odd. I am using two RB133c with XR9 for a WDS bridge, upgraded from 2.9.46 through the RC’s and up to 3.3 without issue.
RB133 or R133c? Just a single card, if its a RB133?
Sorry, I meant RB112 all the time. I don’t know where that mistake came from, I don’t even have any RB133…
