After a few tries and re-searching for this web page I was able to D/L these files. Also I had trouble with 2 versions of the Zyxel firmware sites, one with a march version and one with a newer July version. Following the win7 directions above,and using tcfpd64 - I tried lots of times with the LAN plugged in and then I, 1. reset the modem 2. plugged in the LAN wire. I then saw the files uploading to the router.
Now if I can figure out why I am having DNS errors. I hope this helps someone. Thanks all. Gray
