Slow transfer between ubuntu 12.04 and network hdd

[joehc]

Any news on this matter?

For me it was a PEBKAC applied to network...

PEBCAS : Problem Exists Between Client And Server

When I upgraded my server I also add some ram modules and do I exchanged some cable...

My bug was a deffective RJ45 cable ... I can notice before because it was plugged on another read-only machine.

The only thing I have done before changing the cable is to downgrade my network driver realtek r8169 to r8168, by adding a new package repository taht old propretary firmware (nonfree)(debian repo, since I have migrate to debian)

To check if your network adapter is a realtek, you can type this :

lspci | grep r816

Good Luck !

Well, I get this:

Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)

So I should find another driver version?

I've solved this issue for myself. I did fresh installs on an old Dell Vostro. 12.04 then 11.xx then 10.xx and all slowed down my wireless transfer dramatically (see posts above).

After a lot of screwing around I suspected the network card driver. The answer is that the Vostro has a low power version of the Broadcom wifi chip... from lspci .

Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

I suspected that Ubuntu was installing the driver for the regular chip. The regular chip driver can be installed with ...

sudo apt-get install firmware-b43-installer

Removing the Ubuntu installed driver and using the above command line gave the same painfully slow network but ... installing the low power version ...

sudo apt-get install firmware-b43-lpphy-installer

has my network running at its usual fast pace.

Thanks for your answer

But does this not only concern wireless connection? I am using lan-connection and still I have the slow transfer

Some of us are having related issues. Have you tried from a Windows client to the linux samba server?

Wuhu, it just automitically started working. Must have been an update. Anyone else who can confirm this?

i have the same issue.
win7 network speed perfect, ubuntu 12.04 very slow speed to same pc

Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)
and I have changed driver to R8168 driver but still get transfers under 100kB/s


ubuntu 12.04 64 bit btw - still can't change my user details!

Even stranger - sme network to another pc 86 MB file 2 seconds to the other pc 14 mins for the same file yet in windows 2 seconds.
Could this be a pc specific issue to the one machine perhaps?

same identical problem here with ubuntu 12 and lspci:


04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)


if I upload a file from win to linux I get 100-200kb/s which is SLOW, but if I do the other way around I'm 30kb/s which is total crap.

must find a fix asap, cannot have a LAN like this
