hi all!
I am making a board for hostap!!
Main processor is the MPC 855T, and my board has a PCMCIA slot for WLAN PCMCIA Card. However, the tx rate of my board is something wrong.

external ftp server ---(100M Ethernet)---> my board ---(wireless)---> ftp client(notebook) At this environment, download rate is 300Kbytes/sec

ftp client(notebook) ---(wireless)---> my board ---(100M Ethernet)---> external ftp server At this environment, upload rate is 600Kbytes/sec

The consol of my board say no error report......

someone help....me.....
