Well... good news and bad news.
The bad news first: I won't be able to use yet any of the good advice collected here.
The good news: Contrary to the Netgear horror stories I was able to hard-reset and update my current router and all is well. So both new routers will be dropped off at Kohl's tomorrow...
I do appreciate all your inputs and will refer to them again when the time comes to replace the router. And to all the wifi skeptics (and believers): If any of you happen to pass through upstate SC and have an hour or two to spare, drop me a line here with some advance notice and we will welcome you to our home for a brief (or longer) audition.
Cheers,
Yoram
