I have two points that seem very healthy, yet they tend to disconnect several times a day. Please Help.

Site A: RB433AH + XR9 ROS V4.10 12db Sector Antenna
Site B: RB433AH + XR9 ROS V4.10 12db Rootenna Patch Antenna

2Ghz-10Mhz
Noise Floor: (A)-92dbm (B)-87dbm
Signal Strng: (A)-69dbm (B)-68dbm
SNR: Both get between 20 and 25
Data Rate: Is currently Statically set at 6mb
Both set to "ap bridge" and use WDS
I have set Tx Power to 15dBm. Default is 18dBm (At default they seem to over power each other, Signal in the 50s)
Minimum LOS obstructions about 2.5 miles apart


Here is a sample of the Log on Site B:

I'm noticing some people are having issues with WDS. Would I be better off doing a PTMP bridge? Site A is connecting to several other access points.
