Hey!
My ISP provides 1 GB line which is about 900mbps when my PC connected directly to their device (which set up as a modem).
However when I connect my router to the ISP's modem the speed is much slower 5-700mbps.
I use an ASUS RT-AC68U and cat5e cables. Is there any specific setting that I should use in my router?

Thanks in advance,
Tom

500-700 mbps is more than enough for a consumer grade router to be labled "gigabit". Also, that router is actually doing multiple things...routing, switching, access point. So if you have wifi devices connected, other wired devices that could cause slowdown or just the overall overhead the device is 3 in one. But its more likely that its just because "gigabit" devices often don't deliver as promised.

Thanks for the quick reply!
Could turning on QoS inscrease the speed if I prioritize my PC?
 
The RT-AC68U's routing performance (WAN-to-LAN) in Small Net Builder's review was only about 750 Mbps. So you are getting slightly worse than that. The review noticed that it seemed to prioritize uploads over downloads, so if any traffic was going out (from your LAN to the Internet) at the time you ran the speedtest, it would have lowered your download speed slightly. You might be able to improve it a bit by prioritizing your PC, but I would expect about 750 Mbps max download speed (WAN-to-LAN) with this router.

You will need to get a different router to reach the max speed your ISP is delivering. Browse Small Net Builder's router reviews. They do a pretty comprehensive suite of tests (routing, LAN, storage, WiFi), so you can zero in on the router which best meets your needs.
