Sounds like you're getting a problem with auto-negotiaation, I've come across this numerous times where the through put just crawls.
There is the "ifport" command will configure a port to a specific setting, if you run it with no options it says: # ifport usage: ifport interface [auto|10baseT|10base2|aui|100baseT|##] it will also tell you what the port is set to, like so: # ifport eth0 eth0 0 (Auto) Also try checking the settings of modinfo for the driver and adding options in the modules.conf if you want it at boot time. Disable auto negotiation. The fact the IBM card is using the Xircom Cardbus driver just means it's most likely a rebadged Xircom card.

After my linux boot up, I found this card can be recognized and I can also use this card, but if I want to copy(ftp or scp) some big files into my computer, the speed becomes very slow, this problem only happens on IN direction, for OUT direction, the speed is good. Below is the output of lsmod: Module Size Used by Not tainted xircom_cb 7680 1 ds 8384 2 yenta_socket 11936 2 pcmcia_core 49888 0 [ds yenta_socket] autofs 11076 0 (autoclean) (unused) ide-cd 30112 0 (autoclean) cdrom 32032 0 (autoclean) [ide-cd] sd_mod 11580 0 (autoclean) (unused) scsi_mod 65536 1 (autoclean) [sd_mod] nls_cp437 5120 1 (autoclean) vfat 11836 1 (autoclean) fat 36024 0 (autoclean) [vfat] nls_cp936 124896 1 (autoclean) nls_gb2312 996 3 (autoclean) usb-uhci 24420 0 (unused) usbcore 71552 1 [usb-uhci] Seems my linux is using xircom_cb as driver for this card? Then I go to /lib/modules/2.4.18-3/pcmcia, but there is not a driver called tulip.o as I expected. My questions are: 1. what driver should I use for this card? If it should be tulip, how can I build this driver from kernel source code? 2. How linux use xircom_cb as driver while in /etc/pcmcia/config, it shows the driver for this card should be tulip? I just want to know how linux find the driver for network card when booting up. thanks in advance Yongming __________________________________ Do you Yahoo!? Yahoo!
