The Asus RT-N56U Black Diamond is a new router designed by Asus with dual band simultaneous technology. The previous router models by Asus are not designed with dual band technology such as Asus RT-N13 and RT-N16 routers.

Main features:

• Simultaneous dual band N600
• Gigabit Ethernet ports
• Two USB ports
• Built-in media server with DLNA compliant

Since the first time this Asus RT-N56U is released into the market, it’s received very positive reviews from the users with averagely 4.1 out of five stars customer ratings in Amazon. How do you compare this router with Netgear WNDR4000 N750 router and other high performance N600 / N750 routers?

I will make a comparison table between the Asus RT-N56U Vs WNDR4000 N750 router only lists the main features.

High Speed

Both routers are powered by the latest wireless 802.11n standards but with different speed. RT-N56U is a dual band N600 router delivering total bandwidth up to 600Mbps (300Mbps each band) with Ai Radar technology for reliable wireless network coverage within your large home or small office. On the other hand, the WNDR400 is designed with N750 wireless technology with total bandwidth up to 750Mbps (450Mbps in 5GHz band, 300Mbps in 2.4GHz band) with 6xinternal antennas MIMO technology. Both routers create solid connections with large range coverage.

For wired connection, both routers are embedded with 4xGigait LAN ports and 1xGigabit WAN port. Both LAN and WAN ports provide reliable wired connection you can connect to any types of gigabit-based devices for optimum data rate transfer.

With gigabit WAN port the routers are ideal in connecting to any types of Gigabit-enable modem such as Surfboard SB6120 DOCSIS 3.0 cable modem or Surfboard SBV6220 VoIP gateway modem.

USB Functionality

What I like with the Asus RT-N56U is that it is equipped with two USB ports, attach both external disk storage and printer at the same time and share them across the network. no need of purchasing a wireless print server to share the printer across the network, just send your printing jobs from your computer anywhere and the system will take care of the printing queues.

And the good thing is that both routers support built-in DLNA AV media server for seamless connection with any types of DLNA compliant devices.

Performance

Asus is wonderful with 128MB memory RAM for faster processing compared with WNDR4000 with only 64MB RAM. As opposed to the ultimate version of Netgear WNDR4500, RT-N56U has less flash memory which is only 8MB. WNDR4500 supports 128MB flash and 128MB RAM, superior compared with other routers.

Compared with Netgear WNDR3700, the Asus RT-N56U is better features including two USB port (as opposed to 1xport) with the same DLNA compliant, and Asus has more memory (WNDR3700 includes 16MB flash and 64MB RAM).

What about comparison with other routers?

Asus RT-N56U Vs Linksys E4200 as general can be described with the following features in Linksys E4200:

• N750 technology with 6xinternal antennas 3x3MIMO technology
• 1xUSB port with built-in DLNA AV media server – but cannot host USB printer

The lower version of Linksys E series is E3200 which is the same N600 technology with 1xUSB port but doesn’t support built-in AV media server.
