I know this is going to sound crazy, but we had a similar occurance.  Turn the 
power output DOWN.  We did this and our link jumped from 700Kbps to 1150Kbps.


Quoting Colin Watson <[EMAIL PROTECTED]>:

> 1200Kbit/s? or 1200 Kilobyte/s? - We get about 400 Kilobyte/s (400Kb/sec)
> throughput to our backlink. It'd be worth checking the smartbridge
> statistics, see if their is a high number of errors on the ethernet side.
> Also (I don't know if you can do this on SmartBridge AP's) you may have a
> statistic to show the number of retries the customer is experiencing - High
> retries will equate to low throughput. If they have got a high number of
> retries, check their signal strength they get back to the AP client-->AP,
> and finally, check for local 2.4 interference.
