Routing Performance

Routing throughput running the latest Ver.1.72 (R1.15/B1.00) firmware and our router test process measured 232 Mbps WAN to LAN, 232 Mbps LAN to WAN and 240 Mbps total with up and down tests running simultaneously.

Maximum simultaneous connections topped out at numbers indicating an 8,192 limit.

The IxChariot composite plot in Figure 6 shows upload speed lower than download in the simultaneous routing test.

Figure 7 shows the IxChariot plot from the routing throughput tests run with DD-WRT firmware (DD-WRT v24SP2-MULTI (12/17/10) std - build 15940). The extremely high throughput variation you see if from running uplink and downlink tests simultaneously.

Wireless Performance

The WZR-HP-AG300H is Wi-Fi Certified and properly defaulted to 20 MHz bandwidth mode in 2.4 GHz on power-up. I was able to run a Wi-Fi Protected Setup (WPS) pushbutton session with my Win 7 client that resulted in a WPA2/AES secured connection. All tests were run with this secured connection using our wireless test process.

I'll remind you again that these tests were run with Buffalo "Friendly" firmware loaded, not DD-WRT.

I ran a 2.4 GHz Wireless Performance table (Figure 8) for the Buffalo and three top-of-line simultaneous dual-band routers from other manufacturers, i.e. the Cisco Linksys E4200, ASUS RT-N56U, and NETGEAR WNDR4000.

The good news is that the Buffalo is capable of better than average speeds at Location A (strongest signal), clocking in at 85 Mbps running uplink in 40 MHz bandwidth mode. And the 40 MHz mode simultaneous up and download test yielded 109 Mbps total throughput.

But mid-to-low signal level performance (Locations D, E, F) just doesn't compare to the E4200, which turned in mid-teen or better speeds in all runs.

However, throughput stability was generally good with no multi-second deep dropouts observed in strong signal locations. The IxChariot 20 MHz mode downlink summary plot in Figure 9 is typical.
