Athomik,

Thanks for the information.  Yes, I still have the original Yamaha branded 802.11b wifi cards.  I looked up the card you suggested (Ambicon WL1100C-CF WiFi card) and found only one vendor offering them on Amazon in the USA. They were selling a used card for $79.00 USD plus shipping.   

Amazon's website also suggested WL54-CF 802.11g Wireless CompactFlash Card.  This card 802.11g is a more recent version of the older 802.11b card offered and would allow better range, but in the reviews someone tried to use it on a 5500 Sharp Zaurus and could not get them to work.  I'm not sure it would work or be a direct plug and play replacement and compatible with the current drivers on the PRC-100.  I see that there are several vendors selling this version in both new, used and even refurbished.  I picked up a refurbished version of this card for testing purposes for $10.99 USD plus shipping.  I don't expect it to work in the PRC-100, but I might be surprised--since most cards are backwards compatible.

In the meantime, the wifi repeater solution gives me fantastic range with my original Yamaha cards and now I'm even able to control the piano from outside** my condo.  Plus with the wifi repeater setup I'm able to implement wifi secured network on the extended network -- which is great for me living in "the wifi jungle" as my condominium complex seems to be.

**FYI: I don't recommend using the PRC-100 outside your home since may be more prone to getting damaged if dropped or lost.  Last month I checked the replacement cost of a PRC-100 from Yamaha and now I am taking much, much, MUCH better care of mine.  In fact if there were a fire (God forbid) it would be one of the first items that I would grab... that and the most recent backup of my piano's media.
