On one of these groups, I posted about 6 months ago about the adapter
for my router failing after a power outage. Apparently it's not a
power surge but just normal unplugging and replugging that is bad for
many things (especially maybe if they can cool off in between). I
used a universal adapter for a while and bought the exact replacement
adapter, with the D-Link label, on Ebay. Everything fine.

Last night we had another power failure and today, after futile
attempts to get my mail, I see that none of the lights on the router
are on. I hadn't even gotten around to taking the universal adapter
back to it's drawer in the basement!

So I switched to that and it didnt' work, but after I unplugged and
plugged it in 3 times, ALL the lights on the router went on and stayed
on. I ended up unplugging it from the adapter at least 10 times
before it finally started working. And now it's been fine for hours.
