I found a WRT54Gsv1 at Cash Convertors for $5 so decied to play with it and check firmware features. I already had a GSv4. I installed a number of firmwares reseting factory defaults between each. WiFiBox however won't give up the router. Whether I use the web interface or TFTP the upload fails. Is there a special procedure to kill WiFiBox? I still have more to try. Thanks.
