Wireless version incompabilities - WDS mode

Hi,

I am running an “old” version 3.30 based wireless network with 6 MT Routerboards connected using dedicated radiointerface R52 towards a central “backbone AP” all also equipped with second radiocard for user access.

Backhaul is running Static WDS and works like a charm.

I had to replace one of the units with a new Routerboard running version 5.9 and now we have problems…

I am unable to transport IP packages using the R52 in Station-WDS mode (as I use to on all the other) - however a MAC Telnet works like a charm…

When I set the interface to Station mode, I may alter the entire setup on the main AP and gain IP access to the new wds-station.

Here is the detailed setup for the WDS enabled card - what am I missing? Or is the new 5.x versions simply unable to use a 3.30 AP for WDS backhaul? Incompatibility?

Anyone experienced anything similar?

I had all sorts of problems with WDS on v5.11 at a hotel. I downgraded to 4.17 before customers started complaining.

And what is the Problem to Upgrade this 6 devices,
This is my First step if i Change anything!

Nisse:

Do the folowing if you’re using any RouterOS version starting from v4.17:

System logging add topics: wireless, debug.

And recreate the situation, you will receive in the log the debug messages.

After that, post it in the forum.

I believe that your problem is the same as I:

“unicast key exchange timeout”

This is a RouterOS BUG!!! Starting from ros v4 (I had read many posts on the forum and also when searching the web, that wpa2 does’nt work between AP WDS, and also does’nt work between Mikrotik and different WRTs (meaning Ubiquiti, DD-WRT).

They say using ros 3.13 to 3.30 and AP Bridge (WDS) works with ubiquiti and dd-wrt, and also with the same mikrotik. But after 3.30 the bug appears again.

So, what we have here, is a F***ing OLD BUG…
