Apparently, this is fairly (relative?) common. If there is a power
interruption that would result in a reset, or the power is turned off
for a moment, it requires 5-10 minutes before applying power to reset
properly.

Now, mine is doing this.

Has anyone seen this problem and attempted to do anything about 9it
(besides complaining to Dlink, which is apparently fruitless after the
90 day warranty has expired)?

I note that the 7.5 VDC adapter reads 10 V when plugged into it
(under load - no off switch).

Running on a Variac at reduced voltage has some modest effect.

Any information appreciated including "buy another brand" or something like
that.
