Test Setup

rtpic Netgear R6300 802.11ac Dual Band Wireless Router Review

Figure 1.1

The router was flashed to the latest firmware, SPI firewall disabled and the machine on the LAN side is placed in the DMZ.

For the testing of the router's routing throughput, we used two machines, one connected to the WAN port of the router and the other to the LAN port as shown in Figure 1.1. For both WAN to LAN and LAN to WAN tests, we ran two benchmark software, PassMark Performance Test and IPerf. Each test was repeated three times and the average is taken as the final result. Figure 1.2 shows the following parameters used on the IPerf.

Server
>iperf -s -w 128k
Client
>ipert -c [server address] -w 128k -P 5

Matrix21 Max Session Tool was used to test for the maximum number of sessions. Since the maximum connection the machine could generate is 41,000 sessions, which is far less than most of the current routers are able to handle. With reference from Figure 1.3, we devised a method to run a number of  server-client pairs simultaneously. This is accomplished through the use of virtualization. So, 41,000 per pair multiply by the total number of pairs would give the total number of simultaneous sessions.

For wireless throughput tests, one machine is connected to the LAN port and the other by wireless. A 200MB file is then transfered from the LAN machine over to the wireless machine and vice versa. This is to test the upstream and downstream quality of the wireless link. The wireless connection is encrypted with WPA2-AES. The test is performed on the 40MHz channel and the 80MHz channel (5GHz only). The wireless client is then moved to different rooms (Figure 1.5) and the tests are repeated again. This is to compare the transfer quality when the signal line of sight is being obstructed.

Test Results

 

Firmware Version 1.0.2.38_1.0.33

 

Routing Throughput
Direct Connection 942 Mbps
Wan to Lan 930 Mbps
Lan to Wan 925 Mbps
Max. Sessions 32000

Apparently we noticed that the R6300 have connection limiting algorithm. While performing the Matrix21 max session test, we noticed that sessions are established at a rate of 10 connections per second. Letting the test go until it maxed out would take a really long time so we stopped at 32 000.

 

USB Storage Throughput
  Read Write
SAMBA 72.9 Mbps 91.2 Mbps
FTP 96.8 Mbps 141.6 Mbps

For this test we attached a 3.5" portable hard drive to the USB port. The drive was formatted to NTFS. We then transferred a 200MB data payload to the drive. From the results, it looks like writing data to the drive using FTP yield slightly higher speeds as compared to SAMBA.

 

2.4 GHz Wireless Throughput
Location A B C D E
2.4 GHz 40Mhz Downstream 113 Mbps 142 Mbps 121 Mbps 117 Mbps 126 Mbps
2.4 GHz 40Mhz Upstream 101 Mbps 124 Mbps 75.9 Mbps 98.6 Mbps 133 Mbps

Wireless throughput stayed consistent among the five locations. At location B seems to be the sweet spot as it yields the highest results as compared to location A where the wireless client is about two meters from the router. Even the location C which has the most obstructed line-of-sight yields good results.

 

5 GHz Wireless Throughput
Location A B C D E
5 GHz 40Mhz Downstream 148 Mbps 170 Mbps 183 Mbps 169 Mbps 173 Mbps
5 GHz 40Mhz Upstream 104 Mbps 157 Mbps 163 Mbps 154 Mbps 147 Mbps

The similar consistant results can be said with the 5GHz band.

 

5 GHz AC Wireless Throughput
Location A B C D E
5 GHz 80Mhz Downstream 173 Mbps 222 Mbps 200 Mbps 251 Mbps 237 Mbps
5 GHz 80Mhz Upstream 190 Mbps 198 Mbps 192 Mbps 181 Mbps 201 Mbps

With the 5GHz on ac mode, performance gain is about 23% as compared to 5GHz at 40MHz channel.
