I have a similar problem as
where my access permissions to the external usb ntfs drive attached to HG556a Vodafone router sometimes don't allow writing. However, my main problem is that file transfer speeds to and from the drive connected via 100 MB/s LAN is ~500 KB/s. I've posted the following on the Vodafone forum, but I'm not sure when/if I'll get an answer:
I get slow file transfer speeds (~500 KB/s) between my Windows 7 machine and external usb hdd connected to hg556a router. WiFi and Internet access seem to be fine.
I've already posted it as answer in this thread, but now think it may go unnoticed:
Details on File Transfer Speed
I connected my Windows 7 PC via 100 Mb/s LAN cable to the Vodafone hg556a router. I have already flashed it to the software version V100R001C12B037. I connected my external USB 2.0 hard drive formatted in NTFS to the back USB port of the router. I followed instructions and set up FTP and mapped the network drive on my PC.
The result is I can see the hdd fine in explorer. I can copy/read from the drive at ~2 MB/s and can write to the drive at ~500 KB/s. These are extremely slow file transfer speeds compared to when I had that same hard drive plugged straighted into the PC where I'd get speeds of 10-20 MB/s.
This is far too slow to be able to do anything useful with the USB attached data. It is almost as if the USB port is USB 1.1 rather 2.0... I understand that 100 Mb/s lan is only capable of 12.5 MB/s as a theoretical maximum and probably ~10 MB/s as a real maximum. But 500 KB/s is ~20 times slower, which puzzles me.
Is there anything I can do to fix it?
In addition I sometimes get an access error for certain files and folders, but not for others. Interestingly the Vodafone page:
Says that I wouldn't be able to write to an NTFS drive, which is not true. It was only sometimes that I was getting the access error.
It would be nice to have access problems fixed too.
Any help appreciated!
