Hello folks,
I kindly ask for your advice.
I get "only" 23MB/s data rate over wireless with my Netgear R7000. I am testing with an external harddisk plugged into the USB 3.0 port of the R7000.
Here are a few numbers:
Harddisk -> computer: ~90 MB/s (just as reference)
Harddisk -> R7000 -> PC via LAN cable: constant 43 MB/s (on the the first day with the router I got a constant speed of 60 MB/s )
Harddisk -> R7000 ))) Asus USB AC56 in the same room -> PC: 20-23 MB/s
I don't think that the Asus adapter is the bottleneck, because I have 2 of them and if I use them simultaneously (with a second PC, also in the same room) I get these speeds:
disk -> usb 3.0 -> r7000 -> ...
... ))) asus ac56 -> usb 3.0 -> pc1: 12 MB/s
... ))) asus ac56 -> usb 3.0 -> pc2: 12 MB/s
That is almost exactly half the speed for each client, meaning the router is the bottleneck. (right?) Additionally this benchmark suggests that the adapter should be easily able to handle what I expect.
In this benchmark the reviewer gets at least 35 MB/s and up to 77 MB/s, which raises the question: Why are mine so low?
Then I stumbled over these benchmarks where they measured the speed per channel width (20/40/80 MHz) and they got 55 MB/s on 80 MHz and about 25 MB/s on 20 MHz, which is the data rate that I am getting. For me this seems now like my router is clearly not utilizing multiple channels, causing the data rate to be so low in comparison.
So to make it clear - these are my questions:

So to make it clear - these are my questions:
- Are my concerns justified or am I expecting too much? If I am expecting too much, how am I misinterpreting the benchmarks?
- Is my theory regarding the router only utilizing a single channel valid?
- Is it time to assume that the router is defect and RMA it?
- Am I missing/do I misunderstand something?
- Bonus question (not that important): Why can I not achieve a data rate of 60 MB/s over cable anymore?
