Wireless Performance

The Archer C3150 was tested with our Revision 9 wireless test process with 0.9.1 0.1 v005f.0 Build 160707 Rel.64418n version firmware loaded. Channel 6 and 20 MHz B/W mode was set for 2.4 GHz and Channel 40 and 80 MHz B/W mode was set for 5 GHz. The router was positioned in the test chamber as shown in the photo below. Note I propped up the rear of the router to bring the antennas into a straight-up vertical plane vs. their natural angled-back position.

The only other AC3100 / 3150 class router tested to date is the ASUS RT-AC88U. For fair comparison, I retested it with the V9 process and entered the data in the Charts.

The average 2.4 GHz throughput over all points measured is very similar in both downlink and uplink directions.

5 GHz averages show more significant differences in both directions, with advantage going to TP-LINK.

Throughput vs. attenuation plots provide a more detailed look at wireless performance. The 2.4 GHz downlink plot shows the two products tracking very closely until the ASUS diverges at 54 dB of attenuation and drops connection at 57 dB. The TP-LINK stays connected 6 dB longer, indicating slightly better range.

2.4 GHz uplink shows the two products closely tracking again, with a little separation starting at 30 dB of attenuation.

The 5 GHz downlink plots show similar profiles, but with the TP-LINK having generally higher throughput as signal levels drop (attenuation increases).

The C3150's throughput exceeds the ASUS' throughput most of the test range for 5 GHz uplink.

In all, these results show very similar performance in both bands, with the TP-LINK having a slight edge in 5 GHz.
