ISA Card detection problem (Acer Wireless)

Very odd... I've been doing this forever and this is the first time I've ever had a problem with it.

I just picked up the Acer Wireless Networking Kit. It comes w/ 1 ISA card and 1 PCMCIA card (so I can take my laptop anywhere in the house and still be connected to my network). I have a Windows 98 machine with an AGP Video Card, PCI SCSI and Sound Card and 1 ISA Intel NIC. There are available ISA and PCI slots available and available IRQ's.

But for some reason I insert the the ISA Acer card, but Windows does not detect anything there. All IRQ's are set in the bios for PNP (as opposed to Legacy) so they should detect. I have moved the card to another ISA slot (I have 3 total) w/ no luck. I'm pretty sure the card is seated as firmly as possible. There are no jumpers on the card and Acer's web site support ... well, would SUCKS cover it?

Any ideas?
