hi my friends i now have a tplink 840 v6.2 and really it's a wonderfull router, but the problem is the (100 M) ports and the (2.4 Ghz) wifi,

the bandwidth control of this router manage connections by agood way that it gives all pcs the same bandwidth and if i want to change i can easily, and the wodnderfull thing also is the switch that mean i can connect a nas system into the ethernet ports and i can use it by any number of pcs also by the same manner (each pc have the same bandwidth),

please help me to get a dualband router with a gigabit ethernet ports do the same function (gateway and switch), i intend to buy archer c6, is it agood choice ?

my friend has D-LINK and say that it has avery good 5 ghz wifi :
