I have 13.4 on only a couple test sectors and it seems to be fine. I
know it's a PITA, but have either of you tried going back to 13.2.1?
That's where I'm staying for now on the majority of the network.

Eric,
Thanks for bringing this up. We recently started deploying about 30 450 AP's.
Our testing in the field and with customers is producing the same EXACT problem
you just reported.
More importantly, we see this problem on AP's with low SM's to high SM ranges
(5-45). Same firmware.
Let's compare some notes:
1. What antennas are you using?
2. What routers / OS are you using?
3. What sync source are you using?
We see high frame uses even on the AP's with low SM's and great modulation
rates.
I can understand if a large number of SM's have low modulation it will eat up
frames, but the outcome is the same on low and high SM counts.

Subject: [AFMUG] 450 frame utilization and performance issues
We have a few 450 AP's with 30-40 subscribers and have been getting several
slow speed complaints lately. I just chaulked it up to issues with the SM since
the AP rarely got over 20mb/s downlink. We upgraded to 13.4 recently so we
could watch our frame utilization. We started graphing it over night and as you
can see, we are hitting 100% for sustained periods of time. During that time
the AP is only doing approx. 23mb/s. This particular AP has 34 registered SM
and the majority show 6x and 4x with 4 or 5 SM's at 2x and 1x. The performance
is a major disappointment. Anyone else have similar experiences?
AP configuration: 20mhz channels, 2.5ms frame, 10 miles, 75% downlink,
3 contention slots.
Attached is a screenshot of the utilization and sector throughput calculator
from the Capacity Planner R13.
