My processor is running at 216MHZ.And SD bus clock has been set to 50MHZ(max_sdbus_clock=50000000) and dma is disabled(no_dma=1). And it is not at high speed (ie. high_speed =0)
Few questions,
1)Has any body observed the same figures?
2)How to reduce the the Turn around time?
3)Can we use DMA?If so are there any patches?
4)When i make high_speed =1 , the Association with the Access point does not happen, why is it so?
Please share any of your thoughts on the above things.
Thank you,

ping turn around time is not a good measure of WLAN performance. Mobile WLAN boards very actively go into low-power sleep modes, both on board nd with their associated AP. Coming ou of low-power takes time.

Hi All,
I am testing the SDIO-WLAN stack, i am pinging from atheros EVM module to Access point.
And i am getting the following turn aroung times ,
PACKET SIZE TURN AROUND TIME
1. 64 bytes(Default) 6.8 ms
2. 1500 bytes 13.8ms(on Average)
3. 2000 bytes 15.7ms
4. 3000 bytes 19.7ms
5. 4000 bytes No response(full packet loss)
