Slow LAN transfer speeds

Hardware in use

Gigabit 5 port linksys switch
1x Intel® PRO/1000 CT Network Connection
1x100mbit NIC (on other computer)

now, file transfers never EVER seem to go above 1.4mb/s, both computers have raptors in so it is not the hard drives,

i have tried

SMB shares
BulletproofFTPd
GuildFTPd
RaidenFTPd

all give the same result.

Any one know what this could be? seeing as the max should be about 9.Xmb/s

DHCP is not in use
Cables are fine
Full Duplex set on both

What options should i have ticked in my network connections area

An oddity :: from PC - Xbox i get about 3mbit/s

ah well.. any help would be appreciated

Are you using a mapped drive to transfer?
Are you uisng a DNS alias to connect?

How do you know your cables are good?

SMB? Are you using that protocol to transfer or ? Which means you need NetBIOS or Beui installed to get the transfer.

Both NICs are set to 100/full or Auto? Drop your 1000 to work on 100/full and that might fix the problem instead of putting all the work on the switch to go down to 100.

Double check your cables though as damaged cables can cause a big reduction in speed.

many cables have been tested (home made and shop bought)

dont use mapped drives just \\ip\C$

DNS names not in use

They are set to full, and good point i will try with it being 100full not gigabit -> 100full (didnt think it would make much diff but ill give it a go now you have said it)

thank you for the post

Try mapping the drives, which keeps a live connection between them.

Net use [driveletter]: \\ipaddress\sharename [switches]

ex.

Net use F: \\192.168.1.100\C$

Might eb a good idea to try with a direct connection inversed cable(if you have one) just to iron out everything between the computers...

Try the mapped port too!

Tried cross over cable - same issue
Tried mapping drive - Same issue

Did you adjust the speed/duplex on the NIC?

Have you tried to set them to 100/Full each?

How are you monitoring your network connection speed? What program?

Umm then its definitevly something with one of the cards.
Probl something along speed/duplex like riser mentionned.

Do you have the latest drivers? Do you have Intel's chipset accelerator whatever(bunch of *.inf that you isntall for your intel chipset..)

Also when yousay x-box to computer is faster is it xbox to any computers? or on in particular, you could start troubleshooting from there...

Finally I guess theres no way to check the x-box's lan card setting? And do you know the brand of the xbox NIC?

all cards are set to full duplex (no auto negociate here)
no idea what NIC comes in the xbox, and yea, it seems the xbox 's ftpd is pritty fast (in XBMC) however transfering to the xbox // and back is still the fastest thing i can do on my LAN :(

Exepet tryin to swap the "noname" NIC im really clueless!
The Xbox part is especially weird!

What are you using to test your transfer speeds?
How large is/are the file(s) your transfering?

How long does it take you to transfer that file currently?

You're transferring PC to PC and getting the slow speeds - not transfering to the XBox and getting the slow speeds, righte?

Does each device have a different brand of network card? I sometimes get very low speeds between different brands of network cards. I know it shouldn't matter but I've seen it. My moms computer would get about 2mb/s to my file server while every other machine in my house got almost 11mb/s (on a cisco 2900xl switch). Her computer had a netgear card instead of 3com which all the other computer had. I swapped a 3com in and she was up to almost 11mb/s.

Had a similar problem to this and it turned out to be 4 x 470MFD electolytic capacitors in the power supply filter section of the Linksys switch. The capacitors had "vented" and were no longer doing their job.

Once I'd replaced them the data transfers via the switch were comparitable with transfers that didn't use the switch.

If you have a 3Com card, did you enable Jumbo frames?
I got similar problems some times ago with this feature
