Replacing UBNT transparent link with MT

OK… I am going crazy trying to replace a Ubiquity PS2 (AirOS 3.1) backhaul link with an MT solution. here is how the network looks now:

Point A: UBNT PS2 10.0.0.60, AP, Bridge Mode

Point B: UBNT PS2 10.0.0.70, Station, Bridge Mode
UBNT PS2 10.0.0.80, AP, Bridge Mode
RB333 10.0.0.71- XR2 10.0.1.1(NAT), XR2 10.0.2.1 (NAT)- Client Access Points- WORKING FINE!!!

Point C: UBNT PS2 10.0.0.85, Station, Bridge Mode
UBNT PS2 10.0.0.90, AP, Bridge Mode
RB333 10.0.0.71- XR2 10.0.3.1(NAT), XR2 10.0.4.1 (NAT)- Client Access Points-

Point D: UBNT PS2 10.0.0.95, Station, Bridge Mode

I want to swap out .80 and .85 for a pair of RB333/XR5. I need this link to remain transparent for monitoring purposes. I am having a hell of a time coming up with a configuration for this. I am having a serious throughput problem on the UBNT link (red stuff) and need to solve this immediately. If such a link is possible on AirOS… its GOT to be possible on RouterOS.

I have had no problem configuring and deploying RB333s as client access points, and cannot figure out what i am doing wrong. if anybody could share a configuration or tutorial on how to accomplish this, I would be most grateful. Havent found one in the wiki that does the trick.

thanks

i do not know how your bridge on UBQT, but on routeros, you have to follow rules of 802.11abg

so - you cannot bridge station - therefore RouterOS have WDS to do the task

create AP, you can bridge that without problems, because 802.11 allows that, and then you have to enable WDS on that AP and connect station-wds to that ap from other box and now, you can bridge that statin-wds wireless link without any problems.

here is link to manual, look for WDS.
