I am interested in the actual (i.e., measured) power consumption of a Netgear WNDR3800 router (also known as N600 wireless dual band gigabit router)
I couldn't find any reliable indication online, and deriving it from the adapter specs (12V DC @ 2.5A) in the manual is too imprecise.
I found a value for the slightly related WNDR4000 and WNDR3700 (7 – 7.9 Watt) but I am not sure the power values are similar. In this light, the one value I did find online for the WNDR3800 says about 5 Watt, which seems unrealistically low.
Edit: I can't measure the power consumption myself, as I don't own this type of router.
Edit2: I have this router now, so I measured the power consumption and wrote the results in an answer below.
