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.

As a general rule, based on typical product design of older equipment,
a power reset is only reliably achieved through disconnection of power
for a few minutes. I use a 5 minute rule, based on worst case
experience with larger machines - with experience this can be reduced.

Reset buttons and even on-off switches can not always be counted on to
do this.

If you only want to do this only once, it's worth the extra wait,
particularly if there are many suspect devices (including PCs) in the
possible fault chain. With experience, some fault-specific components
in the chain may be identified to reduce any running around.
