Wireless connection via router from WinXP to Win98

I would like to establish a wireless connection from my
Windows XP system, via a linsys router, to my older
Windows 98 system. The linksys wireless adaptor doesn't
have a driver for Win98 straight out of the box, nor does
their website have a downloadable driver for Win98.

Can anyone recommend a wireless networking card for
Windows 98 with available drivers. I can connect the card
via a USB port (preferably) or could install a card (with
greater difficulty).

Thanks in advance,

Kathy
