Thanks to everyone. Derrick, the NIC suggestion was great, but not the
answer, unfortunately. Duncan gets the gold star. That reset method does
work very well. It seems to clear everything. I found that the wired router
was nearly dead, really plugging up the works, so removed it, and once the
wireless had been properly reset, it installed like a dream and I'm up and
flying.
Once again, thanks to all of you for the help.
Jeff
