Transfer speed from PC to Asus RT-N66U USB drive using FTP

[Stefan1200]

I have a fast USB drive attached to my Asus RT-N66U router. The FTP server of the router is enabled and my Windows 7 desktop PC is connected using 1 GBit CAT6 LAN cable. For testing purposes I also used a OpenSUSE notebook connected using WLAN and 100 MBit CAT5 LAN cable. Tested all official and merlin firmwares since September 2013.

Since 6 month I have the problem, that I only get slow transfer speeds to the USB drive. That's my result:

Desktop PC (LAN): 2 MByte/sec writing
Desktop PC (LAN): 8 MByte/sec reading
Notebook (WLAN and LAN): 4 MByte/sec writing
Notebook (WLAN and LAN): 8 MByte/sec reading

Last year my desktop PC was connected using WLAN. In good situations while having full WLAN speed I got up to 12 MByte/sec writing and reading speed last year. I had contact with the Asus support, they think my Asus Router is broken. But before I replace that Router I want to know how fast is the writing speed with your RT-N66U? Which protocol you use, Samba or FTP?

No one is using an USB harddrive? I can't believe that.

Hi,

I am not using FTP but Samba to access the N66U routers USB devices: The read speed is up to 15 MByte/sec - depending on how the data is disributed on the HDD.
Currently I have no wirte data at hand (traveling abroad), but I am sure it's also around 10 MByte/sec.

I have a full 1 GBit network with CAT6 cables in all rooms and all devices capable 1 GBit (Modem, Routers and Switches).

Maybe something in your setup brings it down to 10 MBit only?

Edit: Overlooked that you speak about WLAN!
In this case you need to look for the overall WLAN speed: To many other WLAN networks can slow down your speed...

With kind regards
Joe

No, my network speed is 1 GBit. I tried to reduce it to 100 MBit, but no change here.

No, last year I had WLAN. And while using WLAN I had no problems, write speed up to 12 MByte/sec. Now with a CAT6 LAN connection I have only 2 MByte/sec.

That's weird. Now I tested using Samba to upload stuff and I got 8 MByte/sec uploading speed over the whole distance of 1 GByte. That's ok I think (4 times faster than using FTP). But I don't understand why. The FTP protocol has less overhead than Samba, less CPU performance needed than Samba, why it's slower?!?

Can you test something for me? Please test uploading something bigger using FTP. Because the first 10 seconds I also have higher upload speed with FTP. If you also don't get more than 4 MBytes/sec it might be normal for this Router. If you get 10 MBytes/sec or more uploading one 500+ MByte file using FTP my Router seems to be broken and I try to replace it. Thanks in advance.
