RB3011UiAS-RM Speeds

So I Have an RB3011UiAS-RM Router and a 500 Mbps ISP Connection.

I've configured my Router with FastTrack too and I'm only getting a max of 350 Mbps Speeds.
When I've tried plugging in my laptop directly to my provider's modem, I am able to get the full 500MBPs

I Have also configured FastTrack on my Route rand it's on the very top of the list in my Firewall Panel but I'm still getting a maximum of 350 Mbps.
Sometimes when I run a Speed Test, It starts at 450 Mbps and immediately drops down to 350 Mbps or even less (keeps dropping throughout the whole test)

Before I bought the Mikrotik I confirmed that it can handle a 500 Mbps connection easily.

Please help

Can you send a export of your Router?
So we can see what may happen, and help you.

Something very wrong there. Even the RB2011 could do 350Mb without fast track!
Config will tell the story.

So I'm not seen any issue of configurations.
Now repeat the speed test with
/tools profile
open, this command will show you all the processes of the router and how much CPU it's consuming.
Other important think it's to see on the interface if are getting TX or RX error.

Show us the results :D
