ASUS RT-AC87U & RT-AC3200 Routers Review

Performance Testing USB 3.0

While USB has indeed be a mainstay of ASUS routers for as long as we can remember, the AC68U is the first high performance router that also provides USB 3.0 and not just USB 2.0 ports. As most consumers know USB 3.0 brings numerous enhancements to the table including higher bandwidth potential and increase power over USB capabilities. As we have seen many times in the past reality sometimes can wildly differ than theory and there are numerous ‘USB 3.0’ devices which actually perform at the same levels as their previous USB 2 counterparts.

To see exactly the capabilities USB 3.0 adds to these routers we devised a very simple test. Using an empty Seagate GoFlex Slim 320GB device we connected it to the USB 3.0 a port of the router. We then configured it as a network drive and using MS RichCopy measured the performance via wired, 2.4GHz wireless and 5GHz wireless.

Both models are equally impressive when it comes to USB performance, and we honestly would not be able to choose one over the other.

Signal Strength tests

A good strong signal is a prerequisite of high performance wireless networking. If a device can barely send or receive a signal, the speeds will be very low as both devices will opt for a slower connection speed to compensate. To test signal strength we use inSSIDer, a program which can graph signal strength of all wireless signals being received by the computer’s wireless NIC.


Since there are no 4×4 networking devices available right now the AC87U is at a distinct disadvantage here. However, because it does have four antennas to choose from its longer distance performance is rather impressive.
