I have the same problem. I'm gonna try horizontal polarization on the backhaul circuit next. This is really killing us.

Subject: [smartBridges] AirBridge Outdoor firmware problem.

I mentioned a few months ago that with the AirBridge
firmware 0.09.10 (transparent bridge) I was able to get
two PPPoE clients on the network behind it at the same
time.
 
I've now verified in a live environment that the latest
firmware 0.01.07 does NOT allow multiple users of ANY
kind to log in to a MikroTik box. While a customer was
logged in and functioning with PPPoE, my laptop could not
get a PPTP connection, and another customer with PPPoE
couldn't get on either.
 
I downgraded the firmware to 0.09.10 and everything started
to work that way it's supposed to.
 
Having said that, here's the problem I've been wrestling with
for 3 months now.
 
The Access Point is an ABI 4.5 miles away with good line-of-sight
to the ABO with a 19db grid. I get 100% RSSI and 92-98% Signal
Quality. When testing throughput from the switch up at the AP I get
just over 2 megabit back to the NOC. When testing from behind this
ABO I have never been able to get more than 700K, and it's currently
getting 450-600K. I just can't seem to get this link to go any
faster.
 
I've tried,
 
- A different radio
- 3 different antennas (13db panel, 15db grid, 19db grid)
- Changed the antenna cable
- moved the antenna base and re-aimed the antenna
 
Any suggestions?
