I'm unable to ftp at more than 10-20 Kbytes / s through a network on which I usually get 400-800 Kbytes / s. This makes my network connection almost unuseful. Below you find a profile of my configuration: 1) relevant /var/log/messages 2) /proc/interrupts 3) /proc/devices 4) lsmod 5) cardctl 6) /etc/pcmcia/config.opts I'd be very grateful for any help / suggestion ! best regards, Nicola 1) lt28:[log]# more /var/log/messages Jan 13 16:54:56 lt28 kernel: cs: cb_alloc(bus 5): vendor 0x10b7, device 0x5157 Jan 13 16:54:56 lt28 cardmgr[381]: initializing socket 1 Jan 13 16:54:56 lt28 cardmgr[381]: socket 1: 3Com 3CCFE575B/3CXFE575B Fast EtherLink XL Jan 13 16:54:56 lt28 cardmgr[381]: executing: 'insmod /lib/modules/2.2.13-14/pcm cia/cb_enabler.o' Jan 13 16:54:56 lt28 cardmgr[381]: executing: 'insmod /lib/modules/2.2.13-14/pcm cia/3c575_cb.o' Jan 13 16:54:56 lt28 kernel: 3c59x.c:v0.99L 5/28/99 Donald Becker http://cesdis. gsfc.nasa.gov/linux/drivers/vortex.html Jan 13 16:54:56 lt28 kernel: cs: cb_config(bus 5) Jan 13 16:54:56 lt28 kernel: fn 0 bar 1: io 0x400-0x47f Jan 13 16:54:56 lt28 kernel: fn 0 bar 2: mem 0x60043000-0x6004307f Jan 13 16:54:56 lt28 kernel: fn 0 bar 3: mem 0x60042000-0x6004207f Jan 13 16:54:56 lt28 kernel: fn 0 rom: mem 0x60022000-0x60041fff Jan 13 16:54:56 lt28 kernel: vortex_attach(bus 5, function 0, device 5157) Jan 13 16:54:56 lt28 kernel: eth0: 3Com 3CCFE575 Cyclone CardBus at 0x400, 00:1 0:4b:f6:a1:57, IRQ 9 Jan 13 16:54:56 lt28 kernel: eth0: CardBus functions mapped 60042000->84058000 Jan 13 16:54:56 lt28 kernel: 8K byte-wide RAM 5:3 Rx:Tx split, MII interface.
