The DHP-W306AV 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 new four-location wireless test process.
I don't test a lot of access points, so didn't have many comparables. But I gathered the results for the Innoband 210P-I1 AP and D-Link DAP-2553 into a performance table (Figure 5). I'm showing only 2.4 GHz results, of course, for the dual-band DAP-2553.
Although the W306AV doesn't beat the DAP-2553 under stongest signal Location A tests, it does pretty well in some locations. Best case throughput was 72 Mbps running downlink in Location A in 20/40 Mhz mode. I measured 90 Mbps running simultaneous up and downlink tests under the same conditions.

Unfortunately, throughput stability wasn't what I would have hoped for, especially under strong signal conditions. And you can see signs of throughput shift in the IxChariot plot in Figure 6 during the Location F test that I also saw in other test runs.
