HARQ is part of the magic. IMO I would enable and set it to one or two
retries.
Uplink and Downlink backoff make the SM's more or less conservative
about which MCS level to use. Basically if it needed a 22 CINR for a
certain rate, it won't switch to that rate until CINR is 22+backoff.
I've reduced packet loss by going to higher values.....there's a
corresponding drop in throughput of course. So hopefully in the long
run you fix the interference and go back to 3.
I miss the 320. There are definitely worse Wimax implementations.

disabled, no retries, what would help?

Under Config->ServiceFlows->QoS Profiles, do the profiles whose
numbers you're using (selected on the Default Parameters page) have
HARQ enabled? How many retries?
Under config->Air Interface -> C/N config, what's the C/N Table Base?
default -70?

There is some nutty madness going on on a large portion of our 320
network, it has hit multiple sites at once.
I know much of its self induced due to too many marginal installs on
very limited access points
good CINR to SMs, even matrix B I cant even get into to manage.
uplink MCS for the most part looks good until i get into the frame
utilization, tons of 16qam 1/2 and 100% usage with only 6-12 mbps
throughput
I have been shifting frequencies across the network because it
presented like interference, and a change on one AP results in
required cascade changes across the 3ghz network since 320 sync
doesnt actually work.
APs are basically default layer 2, no profiles changed, 7mhz channels
mostly ABCD 90s and some split APs. sub counts range from 10 to 35
I migrated a distant part of the network to 10mhz channels and am not
seeing this issue, but subscriber counts are low
Im at my wits end on this nonsense and am about to just put every AP
on the network in SA mode to get a visual on what my spectrum looks
like
we did turn up a 450 facing southwest ten miles south of another 320
AP thats facing south, it blinded the SMs to the 320 on a near
channel even though they were only in the back lobe, but this is far
from the others
any advice from you other guys stuck with wimax would be appreciated
