wndr4300 power?

What should be the voltage and amp on a wndr4300 or N750 router?

I've lost the correct transformer  The back of the N750 says 12V 2.5A.

The transformer I have says 12V 3.5A

The N750 manual says 12v 5A.

I'm confused before I use it I have to know.

Re: wndr4300 power?

You can plug a transforming in if it has the same voltage. It also needs to have at least the same voltage. You can have a higher amperage but not voltage.

  I think the wndr4300 was either 1.5A or 2A. Not sure as I didn't have one but if you've got a 12v 2.5A power supply (provided the polarity is right on the plug) it should work fine.

   WNDR4300[v1] or WNDR4300v2?  Note that "N750" is a speed, not a model
number.  Look at the product label.

 

> [...] The back of the N750 says 12V 2.5A.

 

   Normally, I'd tend to believe the product label.

 

> The N750 manual says 12v 5A.

 

   Where, exactly, in which "The N750 manual" is that?  What I see under
"Technical Specifications" in the WNDR4300[v1] or WNDR4300v2 User
Manual is:

 

      All regions (output): 12V DC @ 1.5A, output

 

(or similar).


   Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation.  Get the User Manual.  Read.

 

   That's inconsistent with "12V 2.5A", so some mystery remains.

 

> The transformer I have says 12V 3.5A


   Should be adequate, assuming the right connector size and polarity,
unless you really believe that "12v 5A" rating.

Re: wndr4300 power?

Thanks for the answers,

 

The only power I can locate in my moving stuff is a Netgear brand that says 12v 3.5A

The WNDR4300 router says on the bottom tag is 12V 2.5A

The manual for the WNDR4300 says it requires a 12V 1.5A

My question is the 3.5A power source too strong when the bottom says 2.5A?

I found the 5A listing in the technical listing of the WNDR4300 papers online so that must be wrong.

It's been a good router and I don't want to burn it up,

 

Thanks.

Re: wndr4300 power?

The 3.5amp is fine. The router won't pull more power than it can use.

Re: wndr4300 power?

In the WNDR4300 manual, in the troubleshooting section, page 123, it says meake sore you are using the 12V 5A  power adapter. I found a non netgear power adapter that says 12V 1.25A, and the router's lights  come on and it is sending a wifi signal out.

My concern is is, In the specs of the WNDR4300 is says 1.5A,

In the trouble section page 123, it says 5A,

The bottom of the router says 2.5A is required and the only Netgear power I've found is a 3.5A,

I.25A seems to light up the router but is it underpowered?

 

So I'm still confused.

   So it does. "5A" is almost certainly wrong.  At 60W (12V*5A), you
couldn't quite make toast on it, but you'd be approaching the regime of
a Kenner Easy-Bake oven.

 

> I.25A seems to light up the router but is it underpowered?

 

   Might be.  The documentation is clearly inconsistent (also called
"wrong"), so it's tough to say which part, if any, is correct.

 

   Among the vaguely similar junk in my collection, I have a DGN2200v4
whose label, adapter, and User Manual agree on 12V, 1A.  I also have a
DGND3700v2, whose label, adapter, and User Manual agree on 12V, 2.5A.

 

   My guess on the WNDR4300 would be that "1.5A" is right, and 1.25 is a
little less than 1.5.  You might not notice that difference, because the
adapter which is rated at 1.25A might be able to put out more, and the
actual maximum demand from the WNDR4300 might be less than its rated
maximum.  Also, that maximum demand may occur only when the radios are
busy, so you might have only occasional problems with a slightly

underpowered adapter.

 

   If the 2.5A value is right, then I'd expect trouble eventually with
the 1.25A adapter.

 

   In any case, I'd expect the 3.5A unit to work reliably.  The 1.25A
unit has a chance, and running the experiment should be harmless.

 

   Given the equipment and the know-how, it would be possible to make
actual measurements of the current under various operating conditions,
but deciding whether you've seen the maximum might be risky.
