Routing throughput running the latest 1.00NA firmware and our router test process measured 93 Mbps WAN to LAN, 94 Mbps LAN to WAN and 142 Mbps total with up and down tests running simultaneously. So you're getting pretty much 100 Mbps wire-speed. The IxChariot composite plot below shows upload speed lower than download in the simultaneous routing test.
Maximum simultaneous connections topped out at 15,993, which is a few thousand better than some of the Cisco E-series routers I've tested, like the E3200 (12,274).
The DHP-1320 is Wi-Fi Certified and properly defaulted to 20 MHz bandwidth mode on power-up. I successfully ran a Wi-Fi Protected Setup (WPS) session with my Win 7 client by entering the WPS code found on the router's bottom label. The WPS session completed quickly and resulted in a WPA2/AES secured connection with the same WPA2 pre-shared key. All tests were run with this secured connection using our wireless test process.
I ran a 2.4 GHz Wireless Performance table for the 1320 and three other high-ranking single-band routers i.e. the Buffalo WZR-HP-G300NH, EnGenius ESR9850 and Cisco Linksys E1500. The Buffalo and DHP-1320 trade off wins in this matchup, with the D-Link winning running downlink and the Buffalo on uplink.
A key factor in the DHP-1320's overall high ranking is its relatively high throughput in weak signal test locations E and F. Its throughput stays up in the double-digits in all tests, except for 40 MHz mode uplink.
DHP-1320 Wireless Performance summary - 2.4 GHz
Throughput stability was generally good with no multi-second deep dropouts observed. But tests at lower signal locations exhibited some signs of rate switching during the one minute test interval. You can see this in the Location F trace in the IxChariot plot below, in which throughput seems to switch back and forth between 20 and 10 Mbps average rates.
