Storage Performance

The summary graphic below from the Router Charts shows all 4x4 routers—both AC2350 / 2400 and AC2600—tested with our standard procedure with USB 3.0 connections and NTFS drive format.

In our most recent review of the TP-LINK Archer C2600, the Linksys EA8500 and topped the charts for both NTFS write and NTFS read. However, for NTFS write, the NETGEAR R7500v2 edged past the Linksys for top-of-the-charts bragging rights. For NTFS read, the Linksys EA8500 remained on top with the R7500v2 trailing even its Version 1 sibling.

Routing Performance

Routing throughput was measured using our standard router test process with the NETGEAR R7500v2 router loaded with v1.0.0.28 firmware. Table 2 summarizes the results and compares them to the same other three routers in the key component summary above. The R7500v1 had the highest simultaneous throughput and all routers supported over 30,000 connections. We consider anything over 30,000 connections as equal for ranking purposes. In terms of real-world performance, you probably wouldn't notice any difference in routing performance for these four routers.

Test Description NETGEAR R7500v2 NETGEAR R7500 ASUS RT-AC87U TP-LINK C2600
WAN-LAN (Mbps) 762 750 787 757
LAN-WAN (Mbps) 799 814 808 800
Total Simultaneous (Mbps) 1454 1502 1392 1416
Maximum Simultaneous Connections 39189 42122 36805 31,784
Firmware Version v1.0.0.28 v1.0.0.52 3.0.0.4.376_2061 1.1.2 Build 20150924 Rel. 66045
Table 2: Comparative routing performance

For the unidirectional tests the IxChariot chart below shows steady throughput but with the LAN-WAN (Uplink) having slightly better through put than the WAN-LAN (downlink). As we have noted in previous reviews, higher uplink throughput is usually observed in this test and is a quirk of the test process, not a reflection of router performance.

As with the previous uplink and downlink tests, in the bidirectional tests, both uplink and downlink test pairs showed very steady throughput. Again, the Uplink pair (red) had significantly higher throughput as well as less variation as shown in the difference in the 95% confidence interval column.

Wireless Performance

The NETGEAR R7500v2 was tested using our Version 8 Wireless test process with v1.0.0.28 firmware loaded. Our standard practice is to center the router under the test antennas on the turntable, both front-to-back and side-to-side in the chamber. This method is intended to keep maximum distance between the router under test and chamber antennas as the router rotates during test. The photo below shows the R7500v2 in position in the test chamber.

The Benchmark Summary below shows the average of throughput measurements made over the tested attenuation range. We'll drill down on the wireless performance in the Throughput vs. Attenuation charts next.

NETGEAR R7500v2 Benchmark Summary

Our throughput vs. attenuation plots compare the NETGEAR R7500v2 with the R7500v1, ASUS RT-AC87U and TP-LINK Archer C2600. As noted earlier, it's fair to compare AC2350 and AC2400 class routers because we use an AC1900 class test device.

For 2.4 GHz downlink, the ASUS RT-AC87U, with the exception at 0 dB of attenuation, outperformed the other routers throughout virtually the entire range. Note that the ASUS is the top-ranked AC2350 class router and the TP-LINK is the top-ranked AC2600 router. Note also, the ASUS does not support MU-MIMO.

2.4 GHz Downlink Throughput vs. Attenuation

For 2.4 GHz Uplink, the TP-LINK C2600 started out with a clear advantage at lower levels of attenuation but joined the rest of the routers at about 24 dB of attenuation. The original NETGEAR R7500 had slightly lower throughput than the other three routers starting at about 24 dB and continuing to the end of its range.

2.4 GHz Uplink Throughput vs. Attenuation

For 5 GHz downlink, the TP-LINK C2600 and the NETGEAR R7500v2 both started with a throughput advantage a lower levels of attenuation (stronger signals) up to about 12 dB. The routers tracked each other fairly well throughout the mid range with the original R7500 dropping below the others at 21 dB of attenuation. The original R7500 was also the first to lose connection at 36 dB.

5 GHz Downlink Throughput vs. Attenuation

For 5 GHz uplink, the original R7500 had the lowest throughput starting at 6 dB of attenuation and remained the lowest through the test range. As with the downlink tests, the original R7500 was again the first to lose connection and it tracked significantly lower than the other three routers.
