Ubuntu Networking :: Philips SNU5600 Disconnects If Uploading Lots Of Data To NAS

Mar 19, 2011

I have a Philips SNU5600 wifi dongle. My wifi network isn't particularly strong, but it has always been reliable, even when downloading and uploading large files such as ISOs to the internet.

I recently bought a NAS, and when I run rsync or try and copy a large file (eg 6 gigs) to the NAS, the connection will eventually fail.

The error message in /var/log/debug is:

Code:

I have read elsewhere that this is a problem with the Minstrel algorithm, so I have tried disabling that by creating /etc/modprobe.d/80211.conf with the following line in it:

Code:

And when I reboot, I am able to run "cat /sys/module/mac80211/parameters/ieee80211_default_rc_algo" and the output is "pid".

However, in my /var/log/debug, there is still the line:

Code:

Here is the output from a few other commands for extra information:


Code:

Code:

Code:

Code:

- The problem has only been around since I got the NAS, and only happens when copying files TO the NAS. Downloading/uploading to internet doesn't cause the same problem.
- This problem happens on two machines both with the same wifi dongle.
- This problem doesn't happen on a laptop running the Intel iwl3945 driver, nor with machines connected via cables, so it is not the NAS which is at fault.

How to get a stable connection when backing up?

Ubuntu :: Copying Lots And Lots Of Data (and Preserving Emblems)?

Oct 26, 2010

I am currently in the process of moving around 20TB of data from one server to another. Security is not a concern, since the data are freely available to anyone on our network anyway. There are a couple of things that I'm trying to decide on:

(1) protocol choice

Of all the choices I have--nfs, ftp, scp, rsync, samba--has anyone done any benchmarking to show which would be the fastest/most robust transfer protocol? I know nfs has slow write speeds for synchronous transfers. Asynchronous would be faster, but less robust. I'm leaning toward rsync since it performs md5sums to confirm the file transfers. (Remember if there's a 1 in a billion chance that a byte will get corrupted, then I'll have 20,000 corrupt bytes in the transfer.)

(2) Nautilus emblems

We use emblems in Nautilus to categorize files. The old and the new server have the same directory structure.Is there any way to copy the Nautilus emblems from the old server to the new server. What I want is that if a user had marked a particular file with a star on the old server, then that file would be marked with a star on the new server when he/she logs in.

Ubuntu Networking :: Tcpdump Shows Lots Of Activity

Jan 24, 2011

The only window that's open is the terminal running this command, no pidgin, skype, samba, torrent or anything I can think of is using the network yet there is ***** load of output from tcpdump. I was hoping to use this to check where certain applications connect to and what messages they send but when I'm doing nothing there is already more output than I can go through. Running tcpdump for less than 10 seconds gives me the following output:

I have set up a local server for testing on my home network and installed openSSH. I can login using filezilla and SFTP and can even download files. Error messages saying cannot find directory (the directory I am trying to upload)?

Do I need to configure openSSH to allow this. I am using my usual ubuntu login. Maybe I need to set up another user for SFTP.

Ubuntu Networking :: Rt270 Disconnects And No Reconnects?

Jan 30, 2010

When I use all the band(transmission or browsing too many videos) it disconnects after few minutes and it doesn't connect again until I reboot.

Ubuntu Networking :: Internet Disconnects Every 2 Hour?

Apr 17, 2010

My internet disconnect mabe every second hour and I have to restart the Ubuntu to get internet again. This started to happen when I bought a new wireless card called NETGEAR WG311v3. The live CD didnt have the drivers for it so I had to download XP drivers and install it with ndisrwapper.

So my question is how do I fix it? Do other network drivers crash with my current one? If so how can I see wish one to remove?

Note that my card works fine with XP on same computer.

Ubuntu Networking :: 10.04.1 - Connection Asking For Passphrase And Disconnects

Sep 16, 2010

I have loaded ubuntu Lynx 10.04.1 as a dual boot behind XP home. I have wireless connection to the XP os via netgear wireless G router and USB 2.0 adapter. The network connection works well with the XP side. When I boot into ubuntu I am sure I have configured the network properly with the wep key and password and the network signal is alive in the work bar at the top of the screen. When I open Firefox and try to browse to ,say, ebay it asks for the passphrase again then tells me that FF is in work offline mode. When I correct this I get asked for the pass phrase again and the connection is disengaged. It just keeps asking for the passphrase and disconnecting. When I reboot into XP everything works perfectly again.

Ubuntu Networking :: Wireless Constantly Disconnects?

Also, when it is disconnected from the network, none of the other computers in the house, wired or wireless, are having any problems. If there is any more information I could provide,

Ubuntu Networking :: Internet Keeps Stalling Then Eventually Just Disconnects

Mar 13, 2010

I just installed Ubuntu this morning and don't have much time to detail my problem before my internet goes out again. I am currently running Ubuntu 9.10 (Karmic Koala?). I just got this laptop earlier this week with windows 7 and decided to put ubuntu on it via Wubi. Anyhoo, I login and then enter my wifi password and eveythings fine. I can surf the internet for a bit and everythings fine. but after a while, the wireless indicator on the keyboard begins to flicker on and off (between a connection and no connection) then starts to stall. The first thing I did was install google chrome (always the first thing to do) and I accidentally downloaded the wrong version A-OK. After I saw I downloaded the wrong version, I downloaded the correct, 32-bit version and installed it. During the download it said I had a 750kBs speed, but took much longer to download than had it been downloaded at a consistent 750kBs speed. I then tried to use update synaptic and it began to download reload all 44 packages and stalled around 38 or so. My internet then disconnected (wouldn't reconnect) and the download failed. I went back into windows uninstalled Ubuntu and then reinstalled it. After going through the first few steps again I began to update via update manager and surfed the web. After a few minutes of surfing the indicator began to flicker than just went off. I then connected to my neighbors internet, continued surfing and then the internet just crashed. I've found that when its just lightweight surfing, everythings okay, but during a download or any 2.0 surfing, then things start to get funky.

Ubuntu Networking :: Linksys WUSB54Gv4 Disconnects After A While On Lucid?

May 4, 2010

This problem is fixed in the upcoming kernel, 2.6.34. You can either wait until Canonical releases the update, or download, build and install the 2.6.34 kernel manually. The instructions to do so are HERE. It's fairly easy.I'm having a problem on Lucid (amd64) with a Linksys WUSB54Gv4 usb wifi adapter. After some time (varies between ~10 mins to a few hours), the connection is lost. However, in my case I can't connect back. It tries to establish the connection, then pops up the dialog asking for the WEP key again. It will do this repeatedly, not ever connecting back.This is basically how the disconnect looks in dmesg:Quote:

[ 2657.920014] phy0 -> rt2500usb_set_device_state: Error - Device failed to ente
r state 1 (-16).
[ 2658.120008] phy0 -> rt2500usb_set_device_state: Error - Device failed to enter state 3 (-16).

Ubuntu Networking :: Linksys WUSB54Gv4 Continuously Disconnects?

Jun 9, 2010

I've recently downloaded, installed Ubuntu 10.04 (june 5 2010)

As title suggests, this is about my USB wireless adapter Linksys WUSB54G ver.4 periodically failing. Now, the exact problem AND solution was posted on this thread:

[URL]

Essentially, I have to try a new kernel or something. I downloaded the kernel 2.6.34 at http://kernel.org/ which is supposed to solve my networking problem. But above thread suggests building my own kernel somehow [URL] and some of its steps are unfortunately not straightforward as copy-and-paste and i'm afraid i can't go on after trying to mimic command prompts a few times.

I tried referring to other sites, like

[URL]

but their suggested steps aren't exactly the same, or maybe they are really but i'm too dumb to see it.

I think I managed to copy the config file (i hope i chose the right one) and put it to the extracted folder of new kernel I just downloaded, but "Build the linux-image and linux-header .deb files" ?

Ubuntu Networking :: WiFi Disconnects When Laptop Is Closed?

Ubuntu Networking :: Stop All Traffic If PPTP VPN Disconnects?

Feb 16, 2011

I use a PPTP VPN for privacy and bittorrent. I have been over all very happy, only taking about a 1/4 hit to my over all network speed. However, I recently downgraded my VPN package, and the new sever I connect through is sometimes unstable with a high throughput. Because of this I am trying to find a way to block ALL (HTTP, bittorrent, email, etc) outgoing network traffic when the VPN fails, and then resume the traffic when the VPN reconnects. Essentially forcing all data through the VPN, and creating the illusion of simply having no network connection to the outside world at all when the VPN is offline/re-connecting. This is opposed to the current situation when the VPN will fail, all my traffic will switch to direct (visible) access through my ISP, and the VPN will re-establish sometime later (2-3mins, normally. Unless I manually restart it sooner).

I have tried Google, but have only been finding information on configuring local web access outside of the VPN for the sake of speed. Information of which I cannot seem to find a way to apply to this.

Ubuntu Networking :: Natty Narwhal Wireless Disconnects?

May 8, 2011

I recently upgraded from Maverick Meerkat to (classic) Natty Narwhal Ubuntu Linux. I am running on a Toshiba Satellite A665 (Intel i7). I use a wireless internet connection. Under Maverick, I had no issues. Under the update, I am finding that occasionally things stop working: The indicator Applet looks fine, but from a terminal, I find that I am no longer able to ping my own router (less than 10 feet away.) This behavior occurs after working fine for a few hours. I am unsure if anything in particular triggers it (I will report back if I determine a particular cause). I have a few other computers (2 running Windows, and the other Maverick Meerkat) -- and they are unaffected. Turning wireless off and on resolves the issue for me on Natty. Rebooting also works. Here's some hopefully relevant technical details about my system:

Code:
~$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
