NETGEAR WNDR3300 Manual page 7

• The model WNDR3300-100NAR is simply a refurbished WNDR3300 with the serial number
removed from the bottom label on the unit.
As of 2/1/2010, units bought in 2009 and 2010 opened up by one user had "Rev 1" etched on the
•
PCB.
• If there are other revisions or you can confirm this information, please update this thread.
Power supply information
Initial refurbs sold in 2008 and early 2009 had stability issues due to bad power supplies.
Most recent models (new and refurbs from mid 2009 on wards) come with a switching power supply:
• voltage: 12 vDC
• amp: 1500mA
• plug size:
♦ 2.1mm ID (confirmed with digital caliper)
5.5mm OD (confirmed with digital caliper)
♦
♦ Center=Positive (center pin)
♦ Shield=Negative
• kill-a-watt reported power usage:
♦ 3 watts on initial boot up or with all radios disabled (idle)
♦ 5 watts with just one radio (with default TX power) - idle
6 watts with both radios (with default TX power on each radio) - idle
♦
Power supplies for this router are manufactured by two vendors (according to FCC information and based on
purchases from 2009 and 2010):
DVE - units from this manufacturer have been known to be bad or inconsistent from the early batches
•
of routers sold in 2008 to mid 2009. Please read the main support thread for more information about
this.
• ITE
It has been recommended to go with a non-switching transformer for those wanting to increase the power to
the radios beyond the default mW per radio. However, some have found it difficult to find such power
supplies (transformer based above 1500mA). A suggestion is to use a *quality* regulated 12vdc 2000mA (or
higher amperage) switching power supply. If you believe to have stability issues that a 30/30/30 reset + full
power cycle may not be not solving... try another power supply if you have one available.
Be sure to review the additional discussions links in the Peacock and main support thread regarding power
supplies and bad capacitors. There have been no known reports regarding the router itself suffering from bad
capacitors.
Internal antennas
1. Netgear advertised 8 antennas, but while 8 are etched on the PCB, even the official FCC info lists 5
active.
2. Three of the five active antennas are for the wl0 radio, supporting 2.4GHz or 5GHz bands.
