Well the WNDR3300 AP has alot of claims on the packaging: 15X speed, 10X coverage, interference avoidance, EIGHT internal antennas.

This is the first 802.11N AP I’ve tried so I had to do some research. 802.11 draft standard N basically means more antennas . This feature is called Multiple-Input Multiple-Output or MIMO.

Dual Band means that it works at can work at either 2.4Ghz or 5Ghz. This is how these products can avoid interference – they can move to whatever frequency works the best. 2.4Ghz is the standard 802.11B/G Frequency and alot of other consumers products (microwave ovens) can interfere with 2.4.

Since I have a problematic basement office I need to connect to, I’m very interested in both the interference avoidance and MIMO features.

Unfortunately, like most fancy wireless APs if you want to get all of the claimed benefits, you gotta use a matching adapters in your desktop PC.

So if you dont have the recommended adapters (WN511B, WN311B, WN111, WNDA3100) your really just going to end up with an 802.11G AP with MIMO (lots of antennas!)

So the performance results…

NETGEAR WNDR3300 <—-> NETGEAR WPNT121 (Rangemax 240) I averaged about 10Mbps. With my older Dell 54G AP I averaged about 9Mbps with the same adapter.

With the recommended NETGEAR WNDA3100 adapter I averaged about 12Mbps and by using a USB extension cable so I could move the USB adapter around I got almost 14Mbps.

Note: The WNDR3300 manual claims that you have to use WPA2-PSK (AES) encryption or else you wont get maximum performance. So I also tested the speed using that encryption setting, it remained at ~14mbps.
