any good settings for 3000mbs internet

hi there is a any good cc for 3000mb up and down r3

If you a 3G connection I don't think you need cc set up but if you want to have A+ on buffer bloat site you need to change your cc settings manually and find what optimal for your own network

It’s only capable of 1Gb. Leave QoS off unless your network is congested with clients using up the available 1Gb. To use 3Gb you can use your old router if it can do the 3Gb and simple put the R3 into its DMZ and connect your gaming equipment to that. 
it’s up to you if the gaming equipment uses WiFi, if not disable R3 WiFi, disable QoS and simple use the geofilter and its options for best service.

Good advice above, you'll be limited to 1Gbps anyway and probably won't need QoS as much, though you could just leave Congestion Control at 100% and use SmartBOOST, you can still benefit from it
