Why is my PCMCIA (PC Card) network card transferring files so slowly?
If you’re using a 16-bit network PCMCIA card (or the 3com port replicator), you’re exchanging data below 10Mbps, which is equivalent to under 1.25 MB of data per second (8 bits make a byte). To improve this, you have to change your network card to a 32-bit CardBus network card (which XPi CD’s support), enabling 10/100 speeds (usually under 16Mbps, or under 2 MB of data per second).
