Previously i have tp link 841n router

Recently i buy archer c6 which has the worsted web admin access page which is literally useless for me because it has a complicated interface with CPU and memory usage . Can you tell me what is the use of this parameter ? And many thing like this which i didn't need .

Also i don't have any control on the router like control client bandwidth , guest network bandwidth control, Chanel setting, router running time and many.

I didn't expect that from this archer c6 router 

This is the worsted experience for me.

can anyone tell me when the next update will come with all of those feature ?
