Do try Virtual Box as then the networking is provided via the virtualization.

I have a virtual Win98 running on my Mac - together with WinXP and Win8. It works great. Only problem - I can't connect to the Internet as it doesn't accept the installed ethernet card (realtek 8029). I found some compatible drivers online and transferred them to Win98 via CD. But even after installing them, it doesn't accept the card, it's still impossible to connect. Internal data transferring (from Mac to Win98 or WinXP to Win98 doesn't work either, Win98 seems to be apart from the other systems.
Is there any way to get this WLAN card working?
