Why do older modem and network cards not work in Windows XP?
Updated: 01/24/2018 by Computer Hope
Tip
Older internal expansion cards that are not plug and play are not supported in any version of Microsoft Windows XP and therefore are not automatically detected and installed.
Get latest Windows drivers
See if the manufacturer of the expansion card provides Windows XP drivers.
Purchase a new expansion card
If no Windows XP drivers are available, we recommend you purchase a new expansion card.
