We won't be covering all the features of the 713P, since they were described in the 713's review. So go on over and read that one if you need detailed info on most the 713P's features.
The 713 to 713P change essentially makes the 713P and SMC's 7004AWBR Wireless Barricade identical twins. Both are sourced from AMIT, who seems to have a chunk of the wireless router market, supplying SMC, Asante, D-Link and Canada's GVC with routers.
The 713P has a new circuit board that keeps the indicators on the front panel, but moves all connectors to the rear... a change that may be welcomed by many home users. The all-plastic enclosure is rounded on the top, so if you want to stack something on top, it may tend to slide off. You probably wouldn't want to stack anything on top anyway, since that's where you need to view the indicator LEDs. The 713P doesn't feel as warm to the touch as the SMC, primarily because of the thermal insulation provided by the plastic box (enclosing a metal bottom chassis and metal top RF shield). Ventilation holes are on each side and top rear of the cabinet.
The circuit design uses the same components, except for a different radio card than the 713 (and also different than the SMC uses). The card is now fully connectorized (PC card bus and antennas) but still fully enclosed and not intended to be user-accessible. This new card adds 128bit WEP encryption to the 713's 40/64 bit, but my performance tests confirmed a similar WEP-enabled performance degradation. The Wireless Performance section below has all the details. On a positive note, you'll be able to enter four Hexadecimal WEP keys instead of one.
The 713P came with an earlier firmware revision, but upgrading it to the latest rev available on the D-Link support Web site added wireless and Wired MAC address control, including the ability to control which wireless clients can associate with the 713P's Access Point. This firmware raises the number of single port mappings (Virtual Servers) to 20 but, unlike the SMC, the number of triggered port range Special Applications stays at 4.
Other differences from the SMC (aside from the different appearance and organization of the admin pages) are:
the 713P doesn't have a DHCP client list on the DHCP server page (but you can view DHCP clients using the drop-down list on the MAC Address Control page).
you can't control the 713P's Admin page access timeout
you don't have an option to discard PING requests from the WAN
That's about it for the features, let's see how it performs!
