When I met EnGenius in January at CES, they mentioned that they had new firmware that significantly improved the performance of their EAP-300 access point that fared so poorly in my review last December. So I promised I'd give it a retest and finally have.
The retest was done with the EAP-300 upgraded to version 1.2.3 firmware, using our standard wireless test process. The AP was set to Channel 1 and the Intel Centrino Ultimate-N 6300 in a Lenovo x220i notebook running Win 7 Home Premium test client was connected using WPA2/AES security. As with the previous test, the AP was left in its default 26 dBm transmit power setting for testing.
The updated throughput ranking in Figure 1 shows the EAP-300 moving up from bottom to fourth-from-bottom position for downlink with a 32.8 Mbps overall average downlink throughput across four test locations vs. 16.5 Mbps in the previous test.

Overall average uplink throughput also improved, but not as dramatically (20.9 Mbps vs. 17.3 Mbps previously).

The IxChariot plot in Figure 3 shows much better stability, with none of the wild swings seen with the previous firmware. Location A throughput increased significantly from 43 Mbps to the 75 Mbps shown below.

If you check out the other plots via the links below, you'll see similar stability in the other modes. I was able to achieve 122 Mbps of total throughput in Location A in 40 MHz bandwidth mode running a simultaneous up and downlink test.
Here are links to the other retest plots for your reference:
- 2.4 GHz / 20 MHz uplink
- 2.4 GHz / 20 MHz up and downlink
- 2.4 GHz / 40 MHz downlink
- 2.4 GHz / 40 MHz uplink
- 2.4 GHz / 40 MHz up and downlink
Figure 4 shows the Performance Table with the retest data.

While Figure 5 shows the original data. Uplink in 20 MHz mode still seems to produce the weakest performance, especially as signal levels decrease (Lcations C, D, F).

EnGenius' new firmware has definitely improved the performance and throughput stability of the EAP-300. As long as you don't expect exceptional range/coverage performance from it, the EAP-300 could serve you well if you are looking for an single-band 802.11bgn smoke-detector style access point and don't mind paying a relatively pricey $100 for it.
