Testing & Results
To test the ASUS RT-N56U Router we are using the Passmark Performance v7.0 Advanced Network Test. This test measures throughput between two clients connected to the router to be tested. In order for this test to work one PC must be set up as 'Client' and the other must be set up as the 'Server', each test is ran five times with the highest and lowest result omitted and the remaining three results are averaged to give a final result. At Benchmark Reviews we like to be comprehensive so you will find results here for many different configurations such as LAN to LAN (100Mb/s), LAN to LAN (1000MB/s), WAN to LAN (Wireless G 54Mb/s) and finally WAN to LAN (Wireless N 150Mb/s). To eliminate any variables Test System 1 was always set to 'Server' and results were monitored and recorded on the 'Client' systems. The ASUS RT-N56U shipped out with firmware v18.104.22.168 (factory default) and was upgraded to v22.214.171.124 prior to these tests.
Test System 1
Test System 2
Test System 3
The first test was conducted at a distance of 1 meter, which I would consider to be 'Wired' range. These tests were conducted using the method detailed above.
Not all results are at their max theoretical limit but this may or may not due to the router itself, it is quite possible that the network adapters themselves are not capable of maxing out their theoretical limit. We see a very good result for 100Mb/s LAN, in this case the network adapters are making full use of the available bandwidth. When we look at the Gigabit LAN result we start to see that throughput is not meeting its maximum potential, in an ideal scenario we would like to have matching Gigabit Ethernet controllers on each side of the test router but we must make do with what we have, still 579 Mb/s is nothing to be disappointed with though seeing as home internet connections are nowhere near as fast as this yet.
Wireless G speeds and wireless N speeds are also somewhat lower than maximum potential, without further network adapters to test with though we must assume that this is the maximum throughput that the ASUS RT-N56U can deliver. Equally important as speed is range when looking at wireless internet, sure you get faster speed with wires but you also lose portability. The next two tests look at wireless G and N150 speed and range. Points 1~3 are downstairs rooms, points 4 and 5 are outside and points 6~9 are upstairs rooms. This gives a good idea of what sort of coverage we can expect in a fairly sized three bedroom house.
The wireless G test is very promising indeed, the ASUS RT-N56U was able to deliver a consistent speed at all but one test point. Test point 5 is the furthest away from the router and is outside so the lower score is somewhat expected.
When we tested Wireless N 150Mb/s speeds the results were sporadic to say the least. Wireless N 150 throughput was not as consistent as the Wireless G throughput. As we see it here, the further away you get from the router, the less throughput you get. It is quite interesting to see that the outside test location (Point 5) gets the same wireless speed for Wireless G and Wireless N 150.
