Features

The WNDR4000's feature set is pretty much the same as the WNDR3700v2's. You can check the WNDR3700v2 review for a summary of the v1 to v2 changes. Here's a summary of the WNDR4000's routing features:

  • DHCP, Static, PPPoE, PPTP, L2TP WAN types
  • IPv6 support (6 to 4 tunnel, Pass Through, Fixed, DHCP, PPPoE, auto detect WAN types)
  • Built-in dynamic DNS client for DynDNS
  • DHCP server with address reservation
  • Static and dynamic (RIP 1, 2) routing
  • UPnP automatic port mapping (NAT Traversal)
  • Single and port range forwarding with separate internal and external port settings
  • Triggered port forwarding
  • Firewall controls: Port scan DoS protection disable; IGMP Proxy; MTU size; NAT filtering; SIP ALG
  • Remote management enable with IP range restriction and port setting
  • Schedulable keyword site blocking w/ trusted IP bypass
  • Schedulable service blocking by IP
  • Uplink (LAN to WAN) only QoS with High, Medium, Normal or Low Priority by service
  • WMM (Wireless MultiMedia) (enabled by default)
  • SMB/CIFS file sharing, HTTP, FTP access and UPnP AV media serving from attached FAT, NTFS formatted drive
  • Emailed logs and alerts
  • Onscreen log w/ enables for allowed/blocked site access, admin access, port forward / triggers, DoS and Port scans, wireless access, router operation
  • Traffic meter with monthly upload/ download / both limit with warn and disconnect options

Missing routing features include:

  • IPsec, PPTP and L2TP VPN passthrough controls
  • HTTPS admin access

Note that the missing VPN passthrough controls don't mean that VPN passthrough isn't supported. It is. But you just can't enable / disable the feature as you can on other routers.

Here is a summary of wireless features:

  • 2.4 and 5 GHz radios with separate controls
  • SSID broadcast, channel, mode control
  • WPA-PSK, WPA2-PSK and mixed security modes
  • Client-to-client isolation control
  • Guest networks on both bands with separate security, client-to-client isolation control and client-to-LAN control
  • Wireless radio on/off (software and hardware switch and by schedule)
  • Fragmentation, CTS/RTS, Preamble mode controls
  • Client MAC address access control
  • Wi-Fi Protected Setup (WPS) support with keep setting control and PIN disable

And missing wireless features:

  • WEP security
  • WPA/WPA2 Enterprise (RADIUS)
  • Transmit power control
  • Connect rate control

Elimination of WEP support seems to be a trend. And at some point we can expect 802.11b support to disappear or at least not be guaranteed.

Channel selection defaulted to Auto for both 2.4 GHz and Channel 153 for 5 GHz. The Mode selector was set to Up to 145 Mbps (20 MHz mode) for 2.4 GHz and Up to 450 Mbps for 5 GHz (40 MHz mode). There are no separate a/b/g/n mode controls. But you can limit operation to 802.11b/g or 802.11a by setting the 2.4 or 5 GHz radio Modes to Up to 54 Mbps. To change the 2.4 GHz radio to 40 MHz mode, choose Up to 54 Mbps and to change the 5 GHz radio to 20 MHz bandwidth choose Up to .217 Mbps.

Channel selection is 1-11 for 2.4 GHz (for US operation) and 36, 40, 44, 48, 149, 153, 157, 161 for 5 GHz.
