The beauty of this protection is, it actually protects you from accessing malware contained website and, prevents any suspicious infected device to infect other devices in your network.


In this crucial part of the AC68U’s true potential, I focused on two main network speed test method, wired and wireless. The devices used for this experiment is the iPhone 7 Plus and ASUS G752VT laptop. For best method of measuring your internet speed, it is highly advisable to use wired over wireless under the minimum condition of using Cat5E ethernet cable.


Below are the outcome of the wired test conducted via laptop.

Based on the test conducted, the first three images show that, the speedtest result from TM’s server shows highest reading followed by the Singtel and finally, the Vodofone UK. The last image was tested with a VPN, BolehVPN to be precise, and, well, the result is acceptable. To conclude the wired test, the router does handle the 800 Mbps like a charm.

The outcome of the wireless test concludes that, my laptop able to achieve over 600Mbps (according to the best test) while, as the distance gets further away from the AC68U, the outcome of the speedtest reduced. Similar to 5 GHz wireless bands, I able to achieve over 200 Mbps (according to the best result), when, I am nearby the router, and, as the distance get’s increased, the speed test result differs compared to the outcome when the test conducted near the AC68U.
