Wireless Performance - Comparative
We have plenty of AC1750 routers to compare the 812DRU with now. Since TRENDnet is going for a price play, I first chose the WD My Net AC1300, which currently sells for around $150. I also added the D-Link DIR-868L because it's a second-generation Broadcom design. And I finished off with the top-ranked ASUS RT-AC66U.
The 2.4 GHz downlink profile clearly shows the 812DRU's problem. While it starts off at a level comparable to the other routers, it starts falling off at only 18 dB of attenuation. The other three routers don't start their throughput decline until around 30 dB of attenuation. Since the TRENDnet didn't run a test at 60 dB of attenuation, that means its 2.4 GHz downlink range score was 0, which didn't help its ranking.
2.4 GHz Downlink Throughput vs. Attenuation
The 2.4 GHz uplink plot shows an interesting spread among the products. The 812DRU is again clearly the poorest range performer, with throughput this time starting its decline even earlier than downlink at only 12 dB. Since again, no test was run at 60 dB, the uplink range value used for ranking was again 0.
2.4 GHz Uplink Throughput vs. Attenuation
The 812DRU's 5 GHz throughput profile puts it more in with two of the three other competitors, even though it tends to run to the low side of the group for many points along the plot in the downlink plot below.
5 GHz Downlink Throughput vs. Attenuation
The same trend is also seen in the 5 GHz uplink profile.
