ASUS AC86U cannot get to full ISP speed

xEllipsis

New Around Here
Hi,

i need some help on the settings on my Asus AC86U running on Merlin 384.8_2.

I have subscribed to 1GPBS. i only get half of 1gpbs in the speedtest.

what should i do to get the full isp speed on lan?

Thanks
 
There are lots of folks on here who know more about this than I do, but since none of them have jumped in I'll try and help.

There may not be anything wrong at all. First off, if you're using wifi to the computer that's running Speedtest you're probably doing great. The value of the fast Internet connection will come up when you have more devices sharing that link. Even if you've got gigabit Ethernet between your router and the computer running Speedtest you are never going to see a full 1 Gbps -- there's overhead on the line between your devices. Make sure you've got a high quality CAT-6 cables, especially if the length is longer, and on the link from your modem to your router as well. If you're still suspecting the router is creating a bottleneck take the router out of the system and plug your computer in directly, and compare that Speedtest result with what you get through the router. Is the spec for your modem up to handling 1Gbps?
 
I'm assuming that you have rebooted the router as the first step in troubleshooting. Next, check the Tools tab and let us know what you see for HW acceleration. What firmware did you have prior to Merlin 384.8_2? Did you factory reset after flashing Merlin 384.8_2?
 
To reach 1 Gbps from your ISP, the device connecting to the router shall have about a 2 Gbps connection to the router.
With a wired connection to one of the 1 Gbps router ports, you can at max reach about 500 Mbps from your ISP.
With a 4 stream connection on 5 GHz to the RT-AC86U you can reach a data rate of about 4x 433 = 1732 Mbps.
The maximum expected throughput will be 1732 / 2 = 866 Mbps from your ISP.
What connection does the client device have to your router?

This is still fun too:

I'm not sure I understand what you are trying to say here. I have an wired Ethernet connection from my computer to my router and get around 940 Mbps each way when running speedtests. Am I missing something here??

Under optimal conditions you are right.
