Asus ships new wireless router RT-N56U with new design different than the previous models (RT-N13 and RT-N16). Unlike the previous models which white is the dominant color, this new model is dominated with Black, an elegant design you will like it. You may also have a look the newer Asus RT-N66U N900 router.
What this Product Does
Simultaneous Dual Band
Asus RT-N56U Black Diamond is powered by 802.11n with simultaneous dual band technology to support both 2.4GHz and 5GHz frequency bands at the same time provides you double bandwidth. With dual band, you can surf the webs, read email using the 2.4GHz band. While at the same time you stream HD video and play online games using the 5GHz band, a clean wireless signal with less interference.
Gigabit Interfaces
Asus RT-N56U is embedded with gigabit Ethernet ports for its both WAN (1-port) and LAN (4-ports) interface. With gigabit LAN interfaces, you can connect your gigabit-enabled computers direct to the router for high-speed applications including gaming and streaming.
If you subscribe broadband cable modem and currently use SB6120 DOCSIS 3 Cable modem, you can connect the modem (with gigabit Ethernet port) to the WAN port of the router for optimum data throughput. SB6120 supports the Gigabit Ethernet port for high speed data transfer between the modem and the router. In addition, RT-N56U is powered by the hardware-based NAT acceleration engine providing WAN to LAN data throughput 2-5 times that of traditional software-based NAT gigabit routers.
Two USB Ports
Like the previous version (RT-N16 router), the Asus RT-N56U Black Diamond simultaneous dual band router supports two USB ports to let you connect the printer and USB external hard disk storage for sharing across the network. It also supports all DLNA standard compatible devices, as well as FTP, SAMBA, UPnP AV server.
Not many home wireless routers support the USB port, and not many wireless routers with USB port support the printer for sharing except for share storage. Currently there are few wireless routers with two USB ports for share storage and printer including:
- Belkin F7D8301 Play N600 HD Wireless Dual-Band Router and the ultimate version of Belkin N900 router
- TEW-673GRU Trendnet
- The newest version of WNDR4500 N900 router and the next generation Netgear WNDR4700 media storage router with internal storage (but this one includes only one USB port).

Good review,
Do you think the lack of IPV6 compatibility is a problem? I’m willing to buy a Dual Band Router and I think RT-N56U can be a good option, but I’m afraid about this issue. I know Buffalo WZR-HP-AG300H is compatible with IPV6 protocol. Do you think it can be a better option?
Thanks
I bet that at least the next ten years the ipv6 compatibility is not a big issue. I think IPv6 is still limited to testing, development or education environments. migrating to ipv6 would be lots of projects in the future. an IPv6 compatibility is just for added value of the product at a moment, while deployment of ipv6 for public is still far away.
IPv6 requirement from ISP to home network is still long way away so one should not be too concern. However, IPv6 is being rollout in institutions where security awareness is paramount such as Defense, government institutions, etc. It is not an experimental protocol, it has long past that.
