Wireless Reviews


The AC66 has mostly the same features as the N66. ASUS has tweaked the list via firmware revisions since I last listed them in the N66 review, however. So here is an updated list that applies to both products, assuming you have the latest firmware loaded.

NOTE: The AC66 firmware is undergoing a fairly high rate of change at the time of this review. So some of the features you see listed below might be temporarily removed by ASUS while they are repaired.


  • Static and Dynamic IP, PPPoE , PPTP, L2TP WAN connections
  • MTU/MRU adjust (PPPoE only)
  • DHCP Server w/ lease time setting, default domain and primary/secondary DNS
  • DHCP Client list
  • DHCP reservation
  • Multicast routing and forwarding
  • UDP proxy
  • Switch jumbo frame enable
  • UPnP enable/disable
  • IPv4 Static Routes
  • IPv6 support: Native; Native w/DHCP; Tunnel 6to4; Tunnel 6in4; Tunnel 6rd
  • DDNS support for,,,
  • Five level bandwidth-based QoS for up and download traffic.


  • Firewall enable/disable
  • DoS protection enable
  • Virtual Server/port forwarding for single or multiple ports with TCP, UDP or both protocols forwarded. Separate source and destination ports, not schedulable
  • Triggered port forwarding for single ports, TCP or UDP, not schedulable
  • URL and keyword filter
  • Per client internet access scheduling
  • DMZ Host
  • RTSP passthrough
  • PPPoE relay
  • Ignore Ping Packet from WAN port
  • Outbound port filtering: black/white list with port range, source/destination IP, protocol and day/time filter


  • PPTP server
  • PPTP, L2TP, IPsec passthrough (default enable)


  • Remote Management with user configurable port and HTTPS support
  • Syslog server support
  • Command line interface via Telnet (default disable)
  • Reboot and reset to factory default
  • Save/restore settings
  • Logs: System console, DHCP, Wireless, port forwarding, routing table


  • WEP, WPA / WPA2 Personal and Enterprise (RADIUS) support
  • Wi-Fi Protected Setup (WPS) support, pushbutton and PIN
  • Auto, N-only, Legacy modes
  • Auto and manual channel set
  • Channel bandwidth
  • SSID broadcast enable/disable
  • Radio enable day/time schedule
  • WDS bridging / repeating
  • Multicast tranmsit rate
  • Beacon period, RTS threshold, DTIM interval adjusts
  • Transmit burst (default enable), multicast forwarding (default disable), WMM APSD (default enable) enables
  • Wireless client isolation (from each other)
  • AP/router/Media bridge software mode switch
  • Three Guest networks per radio
  • Wireless MAC address filtering (allow or deny based on MAC address)

Note that ASUS has added secure HTTPS admin access and the ability to limit remote admin access to an IP address or range. Note too, that the AC66 currently (firmware does not expose the transmit power adjustment. This was available in earlier firmware, but was removed because it was showing incorrect maximum power levels in some cases.

ASUS has given the AC66 a Media Bridge mode, like NETGEAR did for its R6300. This saves ASUS the hassle of making a dedicated media bridge for folks who would actually like to try out the draft 11ac higher throughput that they are allegedly buying.

Media Bridge mode doesn't require WDS to work, so will work with any router. Like the NETGEAR R6300, however, there is no scan function to find networks to connect to, so you must manually enter the SSID.

If you don't like running a bridged connection unsecured, you will like that you can encrypt the connection via WEP, WPA or WPA2. You get N and AC link rates only when running unsecured or WPA2/AES, however. I have a few shots about Media Bridge mode in the gallery if you want to take a look.

Table 2 summarizes key wireless settings. Note that both Personal and Enterprise (RADIUS) forms of WPA/WPA2 security are supported and there is one more 5 GHz channel (165) than many other routers support.

Setting 5 GHz 2.4 GHz
Channel Auto, 36, 40, 44, 48, 149, 153, 157, 161, 165 Auto, 1 - 11
Bandwidth control Auto [default]
20 MHz

RADIUS w/ 802.1x
Table 2: Wireless settings summary

ASUS provides three Channel Bandwidth settings on the 2.4 GHz radio, i.e. Auto (default), 20 MHz and 40 MHz, and adds one more (80 MHz) on the 5 GHz radio. When set to Auto, you can't set the operating channel (ASUS labels this the Control Channel, when it exposes the setting).

Like other router manufacturers, ASUS is adding "cloud" features to its routers, which are called AiCloud. The graphic below taken from the AiCloud site summarizes the features, which appear to be all storage and file-access related. The AiCloud menu currently contains only a link to ASUS' Facebook page, which is where you are supposed to monitor AiCloud's progress.

I've put a few images in the gallery for screens that are different than those in the N66 review.
