Hello all!

I have installed this firmware usb-ftp-samba3-dlna-nv60k-broadcom.bin (v1850) on my Linksys E3000. I have enabled the usb support and samba server, I have plugged an hard disk with 320GB(a sata hard disk in a usb box) self-powered by usb, with ext2 filesystem and automount on /jffs, the samba works but the file transfer is very slow: about 2,5-3 MB/s with ethernet or wireless and often the transfer of large files hangs!(exp of large files: 100MB,700MB,800MB,1.2GB etc..) and the router crashes and I need to reboot the router by unplugging the router power chord.
The usb bandwith is 480 Mbit/s = 60MB/s the 5GHz antenna of linksys E3000 with "n" is 300 Mbit/s = 37,5 MB/s the 2,4 GHz antenna with 'n-g mixed' is about 140 Mbit/s = 17,5 MB/s the ethernet is 100/1000 Mbit/s = 12,5MB/s / 125 MB/s but with ethernet or 5GHz "n" or 2,4GHz "g-n mixed" I have about 2,5-3 MB/s is too slow!! If I plug the hard disk with my pc works fine and the bandwidth is very good. Why the samba server of dd-wrt is slow? There is a problem with the hard disk?


Thanks for the help!

Sounds like you are VERY Green. You need to do more reading to understand the technology and not just mathematics.

Ok...and what I need to read to understand the tecnology? And where are the answers for my questions in your reply?

Regardless of the speed 'debate' I think the first thing to figure out is the crashing problem.
Apparently you have tried it using a wired connection so that eliminates any wireless speed or connection issues.

Do you have DNLA turned on or off? If on then I would try with it off and wired then go from there.

The document explains that the typical real world throughput: 10/100 Ethernet (10 MB/s but I have 2,5-3 MB/s), Gigabit Ethernet (40 MB/s but I have 2,5-3 MB/s) 802.11g (3MB/s and I have 2,5-3 MB/s!) 802.11 n (9 MB/s but I have 2,5-3 MB/s). My usb bandwith it's normal? And if the bandwith it's normal...why the router crash during the file transfer?

DLNA on and off, in both cases the router often crash!

Crashes usually mean, that the router is either overheating or there is a problem with the power supply.

It cannot crash due to low resources as dd-wrt always reserves memory for the core in order to still operate even if memory ran out for userspace apps.

The router crashes with dlna on or off during a file transfer. The router often crashes during a file transfer, often in write or read of large file ex a 1,2 GB video file, my hard disk (sataII on usb box, self-powered) is ext2 formatted, I need to enable jffs2 on the firmware for increase stability? What I can do for increasing the stability?
