[ns] tuning up wireless phy layer

I am simulating some communication performance with 802.11. My simulations
always fail to show the results I expect because the wireless-phy seems to
be overloaded. Is there any possibility to tune the throughput? I set
datarate and basicrate to 54 mbps but this cause very slight improvement,
while setting these rates to higher values makes no sense and no better
results. I have 2.29.
Increasing simulation area and number of nodes cause much worse results.
With AODV on a 1000x1000 area with 140 nodes and 30 parallel CBR flows
(64byte*10/sec) I get more than 10 percent packet loss.
