INTERNET SPEEDTEST

Result LAN file transfer speed PC1 to LAPTOP

2.4GHz

For 2.5GHz result you can see that i achieve around 20MBps for upload and 25MBps for download , i was Using ASUS USB-AC56 that is rated 300Mbps Wifi throughput for 2.4GHz . for your information Wireless performance will not achieve it maximum rated speed , what you can get is only half of its rated speed because of interference with the signal from other device , judging from the 2.4GHz result what can i say is it does perform very well and 20MBps to 25MBps for file transfer speed is what i expecting for 2.4GHz in 10 meter away from the router.

5GHz

When it comes to 5GHz you need a direct line of sight of the Router and the WiFi adapter , so in my case USB AC-56 is not in direct line of sight and 10 meter away of RT-AC68U and i still get the maximum of wireless rated speed for USB AC-56 that is “867Mbps” . The result show that i achieve 42MBps for upload and 43MBps for download and averaging in between 45MBps to 47MBps . The result is very good and it was spot on what i was expecting . even in 5 meter away from RT-AC68U the maximum Transfer speed i get is around 47MBps.

If you looking for more performance and speed you can look into PCE-AC68 wireless card rated 1300MBps ( 1.3Gbps) and easily can achieve up to 50MBps of File Transfer Speed or even more with “Turbo QAM” enable

RESULT USB 3.0 STORAGE

AC 5GHz

averaging around 22MBps transfer speed to USB3.0 storage attached to RT-AC68U , i got nothing to say about the speed from what i know the current Firmware of RT-AC68U right is a bit wonky , so i hope there will be an improvement in USB3.0 speed in future Firmware . Judging from NETGEAR AC router USB 3.0 performance can achieve up to 35MBps there absolutely something wrong with USB 3.0 performance of ASUS RT-AC68U

DUAL WAN FEATURE

Here another great Feature that available in ASUS RT-AC68U Dual WAN configuration , if you have a multiple ISP connection , you can use this feature to make use of your multiple WAN connection in just “One Router”

To enable the DUAL WAN feature all you have to do is click on WAN tab on the left side then click DUAL WAN tab on the upper menu , after that just turn it on and select your primary WAN and secondary WAN , you can choose between 2 mode either Fail over mode or Load Balancing mode . Fail over mode meaning if either one of your WAN connection is fail it will use the second WAN connection . Load balancing mode will use both of your WAN connection to balance the workload of traffic going in and out of your WAN connection.

After you enable DUAL WAN to setup your secondary WAN connection go to Internet Connection in the upper menu tab then select you secondary WAN either USB or LAN port then just fill up the information your ISP

KNOWN FIRMWARE ISSUE Version:3.0.0.4.374_262

• QoS Rule set only affected on UPLOAD
• minidlna issue ( cannot not access media server in LAN )
• sometime stuck Loading APP List at USB Application tab
• poor USB 3.0 performance
