Beware the power supply

First, just wanna send thanks to The Wireless Haven, hacks, and Jim. We are all addicted
to good data now.

Now, for the observation.

Beware the power supply.

We put together two setups with 12-volt 2.5-amp supply, WE826, and EM7565.
One worked well, the other not.

After a lot of testing with different combinations of parts, looks like one
of the 2.5-amp supplies was the problem.

What was the problem with the one that didn’t work?

Slow data rate, high ping times, and sometimes no service...

Took apart the 2-amp supply that came with the WE826 to remove the
DC-side wire and connector. Noticed that the solder work was poor.
One leg of an electrolytic cap pulled out from pushing slightly on it, and
the other leg had a bad solder joint, but enough to mechanically hold.

Anyway, put the harvested cable into a 6-amp supply that was sposed
to come with a 2.1-mm jack, but instead came with a 2.5-mm jack.
The WE826/EM7565 combo is running well, just like with the 2.5-amp
supply. Hmm, maybe a fan for the case?
