The issue is that a wireless transfer from my laptop to my USB3 drive connected to my NetGear DGND3700v2 (with latest firmware) is slooooow.
The same drive connected to my laptop gives me around 30-40MBps. When connected to the router , transfer of a 2GB file is stable around 4MBps.
4MBps (4 Mega BYTES) = 32Mbps (Mega BITS) which is crap. my laptop card is claiming to be connected at 300Mbps on a 2.4GHz dual channel wifi network hosted by the router
My laptop is about 2ft from the router.
There is no other wifi or LAN device powered on.
Transfers have been tested via SMB, CIFS, NFS, FTP and HTTP. Typical transfer is still around 4MBps (Mega BYTES)
The problem is in the wireless or router but if the router is transferring at 4MBps to a USB3 (or even USB2 drive) then it must be one pile of crap router - as I said the xfer between USB drive and direct connection to the laptop is 10x faster.
I accept that a hardlink will always be faster than wifi, but the router is hosting a dual stream 300mbps connection, I am 2ft away from the router, the USB3 is a Western Digital 500GB drive high quality, the router is supposed to be a half decent model, and I'm getting about 32Mpbs - nowhere near 300Mpbs , more like a 54Mpbs "g" connection.
Can't be right?
If the problem is the wifi then the link speed reported by Linux is either grossly over ambitious or the router is crap.
How can I pinpoint the problem?
