Fedora Networking :: Slow File Transfer With Wlan0
Aug 22, 2010
I am having a problem trying to transfer large file (~700MB) from one station in my home to another. I have 3 PCs hooked up through a router. 1 is wired to the router and the other two are wireless. One wireless is a laptop that has a built-in Atheros wireless card that was supported during the FC13 install. The other wireless has a plug-in wireless card made by Belkin (F7D1101). I had to use ndiswrapper to get it to work on FC13.(BTW all PCs are running FC13)
The one with the Belkin card is, I think, the problem. The one with the Atheros card will transfer files at a rate of about 8MB/sec to the one with the wired ethernet connection. The one with the Belkin card will not transfer at rates over 300KB/sec to either of the other two PCs. I have tried file transfers both encrypted and not and it makes no difference.
I have connected two computers with each other both having fc installed. Now, when I tried to transfer a file from one computer to another using scp command, sometimes the file transfers very slowly and sometimes very fast. I wana know that why it sometimes transfers slowly. By slow I mean much slower than a file downloaded from a dsl.
this is all on LAN.Whenever I transfer files through the router A to a pc connected wirelessly, the internet hit the speed of molasses. What can I do to rememdy this? I was thinking about having my fedora box connect wirelessly to the internet, through router A, and then bridge via ethernet to router B and then have my pc always connected to router B, so when i transfer files, router A remains unaffected. Is this correct logic?
We have a server and we have instales an Open suse 10.3 on it. We created a Samba server also. Made to share folder, that we acces from network from other computers that have xp.
The problem is if we try to copy from server it is very slow only 100-300kb/s. The strange thing is that if i copy 1 file then its slow but if i start to copy another one the speed gos up to 10-15mb/s. Evry time i want to copy somethin or install from that server i need to start another copy. If i copy from a comp to that server the speed is normal only if i copy from server its slow.
Ok, the only thing I remember doing is changing out my hard drive because it went bad. I swapped in a new one and reformatted with Windows 7. (I can hear the boos and hisses as I type) Anyway, now file transfers are exceedingly slow. They are ~10KB/s when they should be ~40MB/s. The odd thing is that it mostly occurs on large files, but not all large files and sometimes smaller files are affected. Copying files from one hard disc to another on the server, as well as copying from the server to Win7. Local files are not affected. The problem does not occur on my laptop which has Slackware Linux on it.
Another thing about the problem is that when I mount a disc image on a virtual drive, access time is very slow and windows explorer is very unresponsive and often locks up completely.
I have a samba server with Slackware Linux on it and a Windows 7 client. DHCP is configured through dnsmasq. (dhpc-host=<mac address>,<computer name>) Every now and again, dnsmasq seems to conk out when I try to access the network with my Win7 machine. I then have to reboot the server, as my only access to it is via SSH and I don't have a video card in it. After the server reboots everything is fine until accessing the network with my Win7 machine conks it out again.
I've tried different MTU settings, different network cards on the Win7 machine(Dlink and realtek), various regedit hacks, but none of them produce any results.
I've fixed almost everything except this problem. My network card worked fine on Windows but since I switched from Windows, file transfer over the network using my network card is horribly slow, 30kbps max on 100mbps wired connection. I know my network card is working fine, and I'm trying to copy files between my Ubuntu PC and windows PC, I've set up Samba as recommended by these forums, I can transfer files when using wireless connection, but I still can't transfer files at a speed faster than 30kbps on a wired connection.And the funny part is, it's fast when copying files from Ubuntu to Windows but it's slow the other way. And I've tried this with more than 4 different Windows computers.lspci returns this for the network controllerCode:Silicon Integrated Systems [SiS] 191 Gigabit Ethernet AdapterIs there any way of updating drivers or something that I can do to fix this problem
the PC just hangs for ever. No mouse movement, ctrl-alt-del, nothing.
I have downloaded a Linux driver from Realtek but it will not compile. I have the latest kernel-devel, headers, and gcc. I can post compiler errors if anybody would like. They're all apparently to do with missing parameters.
I have a strange issue that I cannot put my finger on. Recently,I installed a new Ubuntu 10.04 server. No extra software yet, apart from openssh-server. The wired connection (eth1) works fine. I then added a wireless card with chipset p54pci, which appears to work with the wext driver. Configured /etc/wpa_supplicant, and /etc/network/interfaces as well:
This is wpa_supplicant:
Code:
This is interfaces:
Code:
After a reboot the machine comes up with both NICs active.
If I do a ssh from another Ubuntu machine to this machine (to 192.168.2.100, so the wired address) it takes about 30 seconds before I get the login as: prompt.
If I change the interfaces file so that wlan0 is not started (I comment out the line auto wlan0, and reboot), connecting from another machine with ssh alsmost instantly gives me te login prompt.
I tried switching the order of both NICs in the interfaces file. Also tried changing the sshd config file so that it only listens on the wired ip address. Both did not help.
Does anyone have a clue why logging in with ssh from another machine is very much slower in response with wlan0 activated than without ?
i have a bit of a problem and it seems i am not alone, google gave me a lot of hits but no solution.i'm running a dual-boot system on my laptop.
ubuntu 9.10 is installed on ext3 windows xp sp3 on ntfs files are on another ntfs partition
if i want to copy a file (or folder) bigger than 250mb my laptop literally gives up until the file transfer is complete. opening up a terminal via keyboard shortcut gives my an idea how long a ice age can last.this happens with ext3 to ext3; ext3 to fat32; ext3 to ntfs and ntfs to ntfs.today i wanted to backup some files (12GB ~4k files) the first 4gb ran with 20MB/s (all open applications grayed out). after 2h i came back to see that only 6GB where done.
I have 8.04.3 server-32bit. It is on an HP 2.3ghz Pent 4 with 512 mb of RAM.I had previously installed Ubuntu and Kubuntu in a dual boot with XP (actually had a triple boot with XP, Ubuntu, and a BETA Windows 7) for a while, Grub got messed up so I ended up wiping it and just put my XP back on it. I have been intimidated by the command line and when thinking server, I tried the 30 day deal with windows Home server, its OK but it's $100.00 for the permenant version.
Anyway, I manned up to the challenge, installed Ubuntu server, set up as SSH and Samba. I administer from PuTTy and WEBMIN, I tried TightVNC but the GUI seemed very useless, so on a reinstall I went headless.The problem is I have alot of MP3 files I want to transfer back to the server that I had previously transfer to and back again from the Windows server, it was sceamin' fast compared to this. I have found threads talking about using NTFS, I have the EX3, or whatever the Ubuntu format is. Could that cause slow transfers, from NTSF through Samba to Ubuntu?
For the past week+ I have been experiencing very slow file transfers, moving files from one HDD to another - both internal, connected with SATA, should anyone care.. When I move any file, regardless of its size, it is moved with 1.1 MB/sec at very best That's a major pain in the behind, even for moving small amounts of data! If anyone could point me in the right direction, or give me a solution
I am trying to move over 1 Terrabyte of files from a two terrabyte drive into my Ext4 drive where Ubuntu 11.04 is installed. The two terrabyte drive is where my winxp used to be and it's currently paritioned into three partitions. I would like to reformat into a single partition that's why I'm moving the files.
When moving the files from the 2Terrabye NTFS partition into the Ext4 partitioned drive, the best transfer rate I could get is 11 megabytes per second. When I transfer from one NTFS drive to another NTFS drive, I could get as high as 70megabytes per second in WinXP. Is there a way to speed up the speed transfer?
Otherwise, the file transfer dialogue says it would take 26 hours to move all the files!!!
Edit: both drives are internal drives connected via a sata II.
I'm experiencing slow speed transfer between two wireless connected laptops running ubuntu 9.10. Using SSH to tranfer files between these two laptops, which connect to the internet via a wirelesss router, with good speed. This is why I'm surprised by this low speed : 52.3 KB/s, averaging 3 hours and 31 minutes for a 700 Mb movie. Is there any way to make this faster ?
I've just managed to access my windows share from Ubuntu but am now getting write speeds (to xp share) of only 9MB/s over my wired network, anyone have any ideas as to why this may be? I've googled but can find no specific answer.
My NIC is: Ethernet controller: Broadcom Corporation NetLink BCM5784M Gigabit Ethernet PCIe (rev 10) (from lspci) on a Dell studio 1737)
I am struggling trying to understand the reason for a fairly slow data transfer rate between two machines. ( tried point to point and also via a 1 gb switch ) One is nfs/http/ftp server ( with raid1 and lvm on top ), the other one my desktop pc. Both OS with default options, no changes to kernel in proc or other sort of thing.

I have a Hitachi SimpleNET adapter (entry-level NAS device) on a Seagate FreeAgent 1TB external HDD (formatted ext3). The NAS device is connected over 100MB/s ethernet to a Netgear Wireless G router. All other devices connect using Wireless G. The NAS runs embedded Linux on an ARM processor and it runs vsftpd and Samba for file transfers.
If I transfer a large file using an FTP client the transfer maxes out at around 2.5MB/s. For my purposes that's good enough, especially considering the Wireless G bottleneck. If I transfer a file from a Windows 7 client (using samba) I get around 2.2MB/s. I know the CIFS protocol has more overhead than FTP and the difference in speed isn't that noticeable.Any combination of Ubuntu and Samba results in me getting less than 1MB/s. I've tried mounting it through Nautilus (GVFS) and /etc/fstab. FTP from this same Ubuntu client gets around 2.5MB/s.
I don't have root access on the SimpleNET to change the smb.conf. I've made a few adjustments to the mount options with no success. how to either speed up 10.04 as a Samba client or mount a folder on an FTP server locally? I've tried both curlftpfs and FUSEFTP. With curlftpfs any write operation results in an I/O error and it crashes intermittently. With FUSEFTP I never got that far and couldn't even browse the folder.
This is a recent problem, and I can't pinpoint any change/upgrade that would cause this. Rsync transfer from Client to Server: sent 11756196 bytes received 1032741 bytes 138258.78 bytes/sec total size is 144333466390 speedup is 11285.81 Pinging back and forth from each machine is fine. No Ifconfig errors Client, but Server has RX packet errors.
Whenever I transfer a movie into my 16GB USB flash disk, my whole system becomes windows-like and unusable!
When i drag the file(s) into the USB disk folder, it starts out fine and pretty darn fast (25mb/sec) then slowly decreases until it's unbearably slow (3m/sec) and as a side effect my whole system starts deteriorating. I basically have to wait for the file to finish transferring before i can use my desktop again!
This has been happening with every version since Karmic (all 64bit)- I put up with it because I don't use the USB stick that much.. but lately it's been my go to source for transfering large files to/from work.
I am running Fedora-13 64 bit on my Dell Laptop, The same Laptop has Windows-7 as well (dual boot system). I have chosen ext3 filesystem while installing fedora. The file transfer speed in Fedora-13 over the network to my network drive comes out to be not more than 5MBPS.Where as in Wndows-7 I am getting the speed of around 10~12 MBPS. Also I found that copying files in USB flash drive is very slow than in Windows-7 . What could be the problem? To add it , I have another Laptop Running Ubuntu-10.04 , which also performs network transfers at 10~12 MBPS. So its just the fedora-13 who has this problem. As far as I remember this was not the case with Fedora-12
i am trying to transfer a file from my live linux machine to remote linux machine it is a mail server and single .tar.gz file include all data. but during transfer it stop working. how can i work and trouble shooot the matter. is there any better way then this to transfer huge 14 gb file over network,vpn,wan transfer. the speed is 1mbps,rest of the file it copy it.

i wanted to learn linux, so i just installed Centos on a thinkpad x200. my wireless will not work. when i try to activate it i get this error:
Determining IP information for wlan0...SIOCSIFFLAGS: No such file or directory SIOCSIFFLAGS: No such file or directory # lspci 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
(and new-ish to Linux in general) and would appreciate some assistance with fixing a problem I'm having with getting wireless working on my computer.Computer specs: Lenovo Thinkpad Edge 520, I5Wireless card: Intel WiFi Link 1000 b/g/n(Note: I also have a Netgear USB wireless adapter, and trying to use this does not solve my problem)I cannot activate wireless. When I go to Network Settings > Wireless, it is listed as "unavailable", and "off". When I try to switch wireless "on", it says "disconnected", but then immediately switches back to "off".Having tried to browse various forums and such for a solution, I tried looking for the file ifcfg-wlan0 under /etc/sysconfig/network-scripts, but it doesn't exist
I've got a problem while accessing the /etc/sysconfig/network-scripts/ifcfg-wlan0 file, CLI's throwing: "Stale File Handle" - there's no access to this file. Problem is the same regardless wlan0 interface is up or down.
I just installed Fedora 13 on a new Dell XPS desktop and some of the networking files are not created/missing. The computer has Broadcom Gigabit wired card and Asus PCE-N13 wireless card. When I type lspci, I see that Network conroller: RaLink RT2860 and Ethernet controller: Broadcom BCM57780 Gigabit Ethernet. So, somehow they are being detected by the OS, but I am not sure if the drivers are installed or why some of the network files are missng.
I am tring to get my linksys wireless router to connect to my laptop that i recently installed Fedora 10 on. Well it is actully running of an external HD. Any way when i boot in windows it connects and works fine, but when i try to activate wlan0 it says "Cannot activate network divice wlan0!" "determining IP info failed..."
