packet capturing capacity of wireless card

Hi,

I am using Linksys WMP600N wireless card. I got help from Yao through Foundry, and got QNX driver for this card (please 
refer Topic # 13340). while testing, I have noticed that it has limitation of number of packets received per second. I 
am receiving only around 300 packets per second, however, in my application I need to transfer 5000 packets per second. 
Each packet size is 125 bytes only. I do understand that wireless has bandwidth limitations, but I am getting only 300 
kbps bandwidth on 54 Mbps wifi connection.

Please advise.

Re: packet capturing capacity of wireless card

Is it slow on receiving side or sending?

if it is receiving, try to change your AP's beacon frequency like 1 per second, to see whether improved? or change 
another AP to see.
also try to capture packets with 
tcpdump -i ral0 -y IEEE802_11_RADIO -s0 to see whether you can get more here.
maybe ifconfig statistics can help too.
