EzQoS Bandwidth Management

This feature provides a simplifed interface for QoS settings. As you click the individual boxes, less bandwidth is reserved for P2P file transfers. Figure 7 shows QoS configured for streaming media. Additional settings for QoS can be made under Advanced Settings, WAN.

Advanced Setting

This button provides a convenient mini site map showing all of the seven sub menus as shown in Figure 8.

Figure 9 shows the Wireless > General tab, which contains the majority of the available wireless settings. The N16 supports a full range of wireless security methods including WPA/WPA2, AES, TKIP and WPA Personal and WPA enterprise.

I'll note that the N16's "out of the box" settings include 40 MHz wide channels. Although the N16 has been recently Wi-Fi certified, this is in violation of Certification requirements. We've asked ASUS if there is a more recent firmware than the Version beta currently posted that properly defaults the wireless channel bandwidth to 20 MHz, but are still waiting an answer.

As with all current Wi-Fi certified devices, the RT-N16 supports WPS using either the PIN code or the push button method for configuring security. It also supports WDS (Wireless distribution system) bridging / repeating. You can bridge between other APs in the WDS mode or choose the so-called "Hybrid" mode in which you can both bridge to another AP as well as service wireless clients. You are somewhat on your own to figure out how to do this however as the built-in help is a bit sketchy here.

MAC filtering lets you accept or reject wireless clients based on their MAC address. An interesting feature found on the "professional" sub menu lets you determine a global time range for each day of the week to enable wireless access. This would be handy if, for example, you wanted to shut off wireless access between, say, 10:00PM and 8:00AM. One "nit" to pick - I would have preferred to have my WPA key obscured rather than being shown in open text.

There's really not much to configure in this submenu. You can change the default network address, change the DHCP range of address that server will assign, and set the DHCP lease time. The DHCP server does support DHCP reservation, but the implementation isn't nearly as slick as what you find on D-Link routers.

On the RT-N16, you have to figure out the MAC address of each client you want to add to the table. You can find the MAC address by hovering over the client name in the client list on the network MAP, but you can't cut and paste the MAC address. On D-Link routers, the current DHCP clients are listed along with their current IP and MAC addresses. From there, you can easily add a reservation with a single click.


Here you configure your WAN connection type, advanced QoS settings, Port triggering, Virtual server, DMZ and DDNS. I was a bit disappointed in pre-populated applications and services found under port triggering and Virtual Server (port forwarding). While the router undoubtedly has the capability to perform those functions, a larger list pre-populated with more games and services would ease configuration for non-experts.

Another place where a pre-populated list of applications would help is the QoS settings. Figure 10 shows that you need to fill in your own port numbers and set one of three priorities (High, Normal, Low) for each service that you want to prioritize. Note that priority control is for LAN > WAN (uplink) traffic only.

DDNS  options

Figure 10: DDNS options

The N16 supports multiple Dynamic DNS (DDNS) services as shown in Figure 11. The RT-N16 supports a free DDNS service hosted by ASUS as well as services from DYNNDS, TZO and ZONEEDIT. I tested the free ASUS DDNS service.

In my configuration, the N16 is behind another router which is connected to the Internet. The IP address resolved by the ASUS DDNS is a private address on my WAN port ( - the address assigned by my router), not my public IP address. However, I suspect if the ASUS router were connected directly to my cable modem and had a public IP address, there would be no problem.

I also tried re-configuring DDNS using the TZO service. After inputting the information and key provided by TZO, I retested to see if the registered domain properly reflected my public IP address - it did. So if you're configuring DDNS with a RT-N16 behind a second router, or your ISP provides you with a private address, TZO's service works behind a double NAT. I didn't test the others.
