Subject: [smartBridges] one user affecting traffic


Hello all,
I have the following setup:
ISP >> router >> backhaul >> router >> Mikrotic (bandwidth control unit) >>
APPO >> ABT

This particular APPO has 30 customers all using the ABT's.

All customers are bandwidth limited at the tower site by the MiKrotic, most
customers are 256Kbps down, 128Kbps up.  The maximum bandwidth purchased on
this APPO is 512kbps/512Kbps.

The problem I've noticed is if a particular customer is doing a download
that lasts several minutes, every other user on that access point sees a
severe degradation in service.  The other customers on that AP see download
speeds drop to about 128Kbps and uploads drop to about 64Kbps.  In other
words, they see a decrease to about 1/2 of what they should have.

We tried setting the RTS threshold on the ABT's to 500 and this had no
noticable effect. (APPO RTS & Fragmentation left as default setting)
Then we lowered the RTS threshold to 256 on all of the ABT's, again, this
had no noticable effect.
We have not set the fragmentation threshold on any of our radios.

We started noticing this phenomena when the number of associated radios on
the APPO reached 20.

My question is, has anyone else seen this behavior and is there a fix?

APPO firmware is 1.4j.8, ABT firmware is 0.01.07

Thank you in advance for any feedback.
