Region : Vietnam

Model : Archer C7

Hardware Version : Not Clear

Firmware Version : Newest

ISP :

I'm using C7 v2. Wireless 2.4Ghz & 5Ghz enabled. Guest network only enable 2.4Ghz.
1. If i want to control bandwidth only 2.4Ghz guest network, is it enough only stick on Guest Network - Wireless Settings - Enable Guest Network Bandwidth Control then input Egress and Ingress values ?
2. I don't know how to setup Bandwidth Control - Control Settings , and how can i control bandwidth only 1 wireless band?

Thanks, please comment if you could help.
