Problem solved, I think. See below.

I had tried that as well with the same result. But that would not have let
me run the backups - they need to be on the same subnet for that to work
(Retrospect Desktop).

And therein lies the problem. After posting the previous note, I did some
more web searching and found some things suggesting that two Linksys routers
don't play together well. So, I pulled out a Netgear MR814 that I had bought
for my father (and was planning to deliver to him next week) and swapped it
for BEFW11S4. It's been running that way for about two hours with no traffic
storm. So assuming no further problems, I'll deliver the Linksys to my
father instead.
