BEFSR41 & a Power Adapter that makes Noise

I have the Linksys BEFSR41 broadband router and the power adapter is
making a "whining" noise. Does anyone know what could be causing
this, will it cause any future problems and is there a way to fix
it??? thanks

Are you sure it's not a low humming noise? Power adaptors don't usually
whine, in fact there really isn't anything in most of them that can wine. In
any case, any power adaptor that makes more then a very low volume hum
should be replaced *immediately*.

your right I guess it is a humming noise, and just out of curriosity
what is wrong with the power adapter to cause that and or what harm
will it do to the router?? thanks

It's OK and in fact normal for a power adapter to make a low humming noise,
and be warm to the touch. If it hums loudly, it could be caused by loose
parts, internal defect causing overload, or something in the router causing
it to be overloaded (least likely cause). A higher pitch whining noise
indicates something oscillating, such as defective voltage regulator
circuitry (also rare to actually oscillate and whine).

Loose parts can eventually short, and it is possible for this to damage the
router. This isn't all that common, but I would not take chances. Linksys
will RMA power adaptors for free without requiring you to send in the old
one. If it's out of warranty, they are still cheap.

I have maybe 12 power adaptors under my desk for this or that device -
router, switch, hub, modem, speakers, USB hubs, etc. None of them make a
noticeable humming noise unless I put my ear close to them. All of them are
warm to the touch, but not too hot.

The short of it is that any noise out of the ordinary indicates something
wrong and is a good reason to replace the adaptor. It's cheap insurance.
