Wifi router usb hdd slow speed on large file transfer

[frodenordheim1]

Short summary: the speed of filecopy to and from USB hdd connected to Netgear R7800 drops significantly after around 7-8GB has been copied, consistently.

More details:

I get around 35 MB/s for roughly the first 7-8GB of data copied from laptop to USB hdd connected to the R7800's USB port via 5ghz wifi.

After the first 7-8GB the speed drops to around 6-7 MB/s. This happens consistently, for both a USB 2.0 hdd with external power supply and a USB 3.0 hdd, hence the problem must be with the R7800 and not the USB hdd's. If I use windows copy or ftp, the copy process will be abrupted after some time (usually around after 10 GB data copied). If i press pause, wait around 10 minutes and then continue the copy process, the copy will continue a high speed (over 20 MB/s) for some minutes, and then drop to lower speeds and eventually be abrupted if not paused again. If I use Teracopy (specialized copy program), then the copy process is not abrupted but otherwise it's the same speed problems.


To me this could seem like a overheating problem, but the R7800 is placed so that it has good ventilation.


Since my guess is that it is a overhating problem, my plan is to add a heatsink on the cpu, drill holes in the front and add fans on both the front and back to allow for better ventilation.


I have the latest firmware V1.0.2.58 installed and the OS on my laptop is Windows 10.


I would appreciate very much if you have some thoughts on this, if it could be fixed in any way?

why you dont plug in the external usb drive in usb on the laptop .

Thanks for a really quick reply. To plug the usb drive in the laptop is not an option in this case I'm afraid.

my setup is so that the Usb hdd has to be connected to the wifi router and not the laptop.

there are several reasons why I want the hdd connected to the wifi router and not the laptop.

I am not sure what you want picture of, and how that can help solve the problem?

Update: problem solved!The issue was weak wifi signal. I moved the router to an open spot and voila - problem solved.Also tested maximum speed via ethernet lan cable - turned out to be around 40 mb/s for around 20GB, then slowed down to around 20 mb/s, steadily for the remaining 20 GB.
