As explained in the title, my router isn't able to support the gigabit internet as provided by my ISP. Around ~200mbs over wifi and for some reason even slower than that other ethernet. Is this the behavior I should be expecting for my Archer A7 or maybe something is wrong? I have recently upgraded the firmware and really hoping to have some answer. If this is the expected behavior could you please kindly recommend a better router that can support gigabit connection so that I don't waste time shoping around? :)

More info:

I notice that CPU load on the router keeps jumping from 15% to 75% while memory usage stays around 31%. Not sure if this make any differences.
