Hi,
I had installed both version of the latest official image on WL500gp.
With 2.4 the maximum file transfer speed from usb hdd is about 3.5 Mb/s through ftp protocol, but with 2.6 it's only 1.2 Mb/s.
I used vsftpd as ftp server and the same settings for testing.
Anyone have an idea what causes this significant difference between 2.4 and 2.6 kernel?
The WL-500g Premium V1 uses a BCM4318 radio, which still has some transmission power problems with b43 (but it should usually work fine as a client). Some cards seems to be more affected than others, though.
Be sure to compile from kamikaze trunk if you're going to use 2.6 on Broadcom, is much more stable than with 8.09.

If you have a V1 replace the wireless minipci with a Atheros card and have fun.
Thank you, it's ok! But I forgot to mention that I tested the file transfer with wired connection, not with wireless. That's why I dont understand the difference.
Just asking... what is the CPU utilization when transferring the file?
With kernel 2.6 the top command shows this:
CPU: 0% usr 36% sys 0% nice 0% idle 1% io 4% irq 57% softirq
Load average: 1.19 0.49 0.20
PID PPID USER STAT VSZ %MEM %CPU COMMAND
1492 1 ftpuser R 1916 6% 86% vsftpd
The discussion might have continued from here.
