Question poor transfer rate with 3CCFE575BT card 

Forum: 3Com PCMCIA Ethernet Adapter Issues
Date: 2000, Jan 13
From: Nicola Botta nicola

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
