Introduction

I have been holding off on reviewing NETGEAR's entry into the sub-$100 dual-band draft 802.11n router race, waiting for Netgear to release its firmware fix for the WNDR3300's low wireless throughput with the 11n radio switched to the 2.4 GHz band [related article].

Well, V1.0.23 was released last week and I retested both the first sample that NETGEAR sent as well as a second sample that was supposed to have lower noise coupling (which was causing the lower throughput). To cut to the chase, I found that the new firmware slightly improved the draft N radio's throughput when set to the 2.4 GHz band. But I also found that, in general, the draft 11n radio set to 2.4 GHz was too unstable for reliable use.

Inside Details

Figure 1 is taken from the FCC ID docs and shows the 3300's board, with its unique two-radio draft 11n / 802.11b/g approach.

The all-Broadcom design uses a BCM4704 processor, 16 MB of RAM and 4 MB of flash. The 10/100 WAN and LAN ports are handled via a BCM5325 switch which is Auto MDI/X.

A BCM4321 Baseband/MAC and BCM2055 2.4/5 GHz Intensi-fi draft 11n transceiver make up the dual-band 11n radio. The second radio is provided by a BCM4318 single chip 802.11b/g chip. Each radio has its own printed-circuit "metamaterial" antennas; three for the draft 802.11n radio and two for the 802.11b/g.
