Paul,
Since I switched the router off overnight the problem seems to have
disappeared. I normally leave it on round the clock, though tried
switching off overnight, for the first time, a couple of months ago.
This was after reading an article that said leaving powered down for a
few hours improves speed. I didn't find that but will settle for today's
result!
