Ubuntu Networking :: Wireless Connecting But No Data Transfer / Solve This?

May 30, 2010

I recently did a clean install of Ubuntu 10.04 and tried using a DLink DWL-G122 dongle for a wireless connection.

It seems to connect to the wireless router, but I cannot seem to access any websites using the wireless connection. Ethernet connections to the computer work perfectly, but ethernet isn't ideal.

The results of the lsusb command is code...

Ubuntu Networking :: 10.04 - Connecting To XP For File Transfer?

Aug 30, 2010

I have ubuntu 10.04 on my netbook and all my files on my XP desktop. How can I connect the two so that I can transfer files from the XP machine to the Ubuntu netbook? Both have WiFi and ethernet. I am not fluent in windows networking but could manage to join two xp machines using an ethernet cable and naming the two with the same workgroup then setting a folder as shared!

Ubuntu Networking :: Transfer Of Data From PC To Mac ?

Jul 26, 2011

Recently I had a situation where I had to transfer data from a PC to a Mac. Usually we simply convert the data as necessary, ie. bookmarks, contacts, etc. move the info to a dropbox account and use Windows networking to access the dropbox from a Mac. Well, there was a network issue and it was suggested that I boot to Ubuntu and do this. We do have Ubuntu on a flash drive but I was lost from there. Can anyone point me in the direction of documentation or assist me in understanding how this would be accomplished? I have a Mac, PC and Linux box at home so hopefully I have all the necessary tools to test this out.

Ubuntu Networking :: Connecting 10.04 With Windows 7 - Transfer Files Like Music - Documents - Pictures

Jun 20, 2010

I want to connect a laptop running ubuntu 10.04 to a laptop running windows 7 via direct connection in order to transfer files like music, documents, pictures, etc. I have an ethernet cable that I thought I would need in order to do it. Is that even possible?? If so, how would I go about doing that?

Now, I have tried to share the files wirelessly but for some reason when I pick up the workgroup on the ubuntu laptop and enter the password in order to connect to the windows laptop it says my password is wrong, when I know for a fact that it is not. I know I can transfer files with a flash drive and what not but I want to try to get this working.

Networking :: How To Log TCP And UDP Errors During Data Transfer

Aug 19, 2009

I am quite newbie with Linux networking and I want to know if there exist a log in Linux where errors during transfers are stored. I mean, when I'm transferring data between two hosts is there any way to log somewhere (where?) the errors or warning during the transfer? That is, connection failures, TCP or UDP errors, etc.? Is there any "log level" to select the errors to be displayed in the log not to work with a huge log file?

Ubuntu Networking :: Internet Connects But No Data Transfer?

Jul 17, 2010

I bought a laptop today (Compaq Presario cq62) and loaded Ubuntu 10.04 on it. Everything has been running great, but the Wifi has been acting up. It connects to my router for a few seconds to a minute, and then stops all data transfer (although it still shows that I am connected to the internet). My other computers running Mac work fine. I took my laptop to another place with wifi, and it did the same thing.

The data transfer seems to stop when there is a lot going on. Whenever I try downloading new software, it gets to exactly 5% then stops. If I disconnect the wifi, and reconnect it works again for another minute. I may need to be walked through any terminal codes.

On that note, where would be a great place to read up on using Ubuntu (online book?)

Ubuntu Networking :: Transfer A Lot Of Data From Laptop To Computer?

Mar 14, 2011

I am trying to transfer a lot of data from my laptop to my computer. Both are running Ubuntu 10.04 and both have Samba installed, and folders are setup for sharing. The laptop has a 56Mbps Wireless G built in module, and the computer has a Airlink AWLL6075 Wireless N USB Adapter 300Mbps. (I got the USB adapter working with the internet, since there was an issue with it just working out the box)

I have a wireless network, since wired is out of the question. The router is a Belkin Play N600 HD if that makes any difference. When i try to transfer the files across the speed of the transfer maxes out at about 785 Kbps (My Internet speed is 7Mbps=875 KB/s). It seems that the file is being sent to the router and then the internet and back to the router and then my computer.

I figure that bottleneck is my Laptop at 56Mbps, but that still gives a theoretical max of 7MB/s even at a low connection/link counting it at 24Mbps would still be 3MB/s. I even tried making a wireless Ad-Hoc network to transfer the files but when i went to Network it wouldn't show any shares.

I'm missing something to make it go faster and i really can't figure out what it is, maybe because I am too close to it.

Fedora Networking :: Slower Data Transfer Rate In KDE V GDM?

Nov 25, 2010

I have a FC13 box that has both Gnome and KDE sessions installed.

I have noticed on the KDE session that data transfer rates are slower than when I use Gnome.

In Gnome, I can transfer files between my FC13 machine and my Ubuntu 10.04 pc at a rate of 6.5 MB/s (52 Mb/s if my maths is correct), but in KDE the rate is only 3.5 MB/s (28 Mb/s).

"ethtool eth0" shows my NIC speed as 100 Mb/s. Obviously I am not hitting anywhere near that speed in either session, (a separate article may be happen in the future to address that), but I am curious as to why KDE is that much slower for file transfer.

Networking :: Connecting To Local Network Data Server?

Jul 1, 2010

I'm trying to connect to a data server (basically a big hard drive) in my lab with my computer. On the Mac that's at the workbench next to me, you enter Go -> Connect to Server. From there, enter the IP address that I have (I can't find a server name--just the IP.). It asks you which subsystem you want, queries you for a user name & password, and then opens a window with all the files. Meanwhile, on my Ubuntu machine, I have a "Connect to Server" option under "Places" on my main menu. But when I choose that, I need to select what kind of server it is, from several options that don't seem right. (It's not FTP, it's not SSH, it's not a form of HTTP, and that leaves "Windows share?") I've tried several things, but usually get back 'Cannot display location "smb://<IP-ADDRESS>/" The specified location is not mounted'. I've tried many ways of mounting this drive, but it usually gives me permission denied errors (even though I *know* I have the right login and password--I've logged in using the aforementioned Mac).

Ubuntu Networking :: No Connection With Ralink RT2501 Wireless Card / Solve This?

Aug 29, 2010

I use Ubuntu 9.04 and try to get a Sweex LW053 USB wireless card (Ralink RT73/RT2500 chipset) to work. According to the Wiki list in the sticky thread, this one should work "out of the box" since 8.04.

lsusb delivers
Bus 002 Device 002: ID 148f:2573 Ralink Technology Corp. RT2501USB Wireless Adapter
and there is also some wlan0 entry that doesn't look too dodgy when typing ifconfig.
From this I get that my laptop recognizes the card.
I also typed in some numbers such as SSID and DNS server address in Preferences>Network Connections where asked (although the information that I had wasn't 100% what was asked for so I tried to guess what needs to be filled in which fields).
However, I don't get an internet connection (Firefox can't find server...)

What else do I have to (or can I) do?

Ubuntu Networking :: Intel Pro / Wireless 3945ABG Stopped Working - Solve This?

Aug 11, 2011

I'm new to linux. I've just installed Ubuntu 11.04. It has all been going ok, but the wireless just stopped working all of a sudden. The indicator light turned off and when I tried to turn it back on (Fn+F2) nothing happens. Sometimes, when I restart the computer, the wireless might work; but if the signal is lost the LED on my laptop turns off and I cannot reconnect. Also, in these strange cases that the wireless works when I restart I can manually turn it off (Fn+F2), but nothing happens when I try to switch it back on.

In the menu on the upper right corner I see 'Enable Networking' is checked, but 'Enable Wireless' cannot be modified.

I have a Dell Inspiron 6400 and the wireless device is an Intel Pro/Wireless 3945ABG.
I have tried to follow some of the threads on this forum on similar cases, but the ones that were comprehensible to me did not work (or I actually might not have understood them either). code...

Ubuntu Networking :: Wireless Crashes During NFS Transfer?

Oct 15, 2010

During NFS transfers my laptop crashes my entire wireless network. Laptop is a Samsung R20, Ubuntu 32-bit 10.04 with atheros AR5001 wifi and ath5k driver. What works: ->NFS is working. I have 3 other machines on wired connections that use NFS happily. And the NFS shares work fine if i plug the laptop into a wired connection. ->Wifi works. I can browse the internet and a large download (700MB) with bittorrent takes 8 mins and doesn't down the wireless.

What doesn't work: ->NFS and wireless together. Any NFS transfer over wireless eventually downs the wifi. Forl example streaming one 3mb mp3 in rhythmbox crashes wireless after playing for about 30 seconds. When the wireless fails it breaks for ALL computers and the only way to re=establish it is by restarting the router. Wired connections remain OK even when wireless is down (both from the same router).->I have a 64-bit desktop with wifi that also suffers the same problem but that doesn't matter so much since it also has a wired connection.

Ubuntu Networking :: Torrent Downloading In 11.04 Causes Unstable Wireless Transfer

Jul 2, 2011

Every time I download torrents in Ubuntu 11.04 on my desktop, using Transmission or Deluge clients, the wireless transfer speed abruptly drops off, becomes very choppy, and in general doesn't remain stable. It's not only the torrent download that slows down, but it's everything including web surfing, even though I'm not maxing out my connection speed. It's not that I'm getting disconnected from my router, it's just that the wireless transfer speed drops off, becomes intermittent, and never gets back up to full speed.

At first I thought that my ISP was throttling my connection, but this issue doesn't happen with a direct cable connection to my router, nor did it happen when I was running Ubuntu 10.04 before. It also doesn't happen when I'm downloading the exact same torrents over wireless using my netbook running Ubuntu Netbook Remix. This issue ONLY seems to happen when using a bittorrent client while on wireless on Ubuntu 11.04 on my desktop. I can max out my internet connection speed by streaming videos, downloading from FTP, etc. using wireless just fine, and the transfer speed remains stable. This also seems to happen with a couple of different wireless USB adapters (rt73usb or rtl8187 drivers).

Ubuntu Networking :: Not Connecting To Wireless

Mar 28, 2010

I recently installed the latest version of Kubuntu in a dual boot system with Windows XP on a Dell laptop. The dell laptop has a broadcom wireless device, and I was able to set up the driver and get wireless working. Then I booted into windows XP to make a whole bunch of updates/driver installations, and when I booted back into Kubuntu it would not connect to the wireless network. I am pretty sure the device is still active, because it picks up on the wireless networks in the area. But KWallet does not open to ask for my password on booting. Something is not set right, but I can't tell what.

Ubuntu :: Getting Error With Burning Data DVD+R - Why Is So / Solve This?

Jan 12, 2011

I don't know what the difference is between DVD+R and DVD-R or if it matters, lol.

I was trying to burn 2.0 GB of data to a 4.7-GB DVD+R and after it finished burning, I got "There was an error writing to the disk."

When I opened the directory of the disk, it appeared that all of the files were there, but when I tried to open any of them, I got "Could not read from the resource" errors.

I tried burning it again to a fresh disk and it was the same except when I tried to open the files it said variations of "error interpreting file".

I checked the log files and mostly it was unhelpfully generic errors, except for this line:
"BraseroLibburn Asynchronous SCSI error on CLOSE TRACK SESSION: [3 73 04] Program memory area update failure"

That part was the same for both attempts. What could be causing this?

Ubuntu Networking :: No Connecting With Wired Or Wireless?

Apr 1, 2010

in short : installed 9.10 on a dell inspiron 600m which has a broadcom bcm4401 ethernet and an intel PRO/Wireless LAN 2100 3B mini PCI. At this point, i'm not too picky about which one works (meaning neither of them currently work). nm-tool seems to pick up on both : the broadcom (eth0) is using the b44 driver, State is unavailable; the intel (eth1) is using the ipw2100 driver, it's State is disconnected.

i have encryption turned off, and the wireless sees a number of AP's (including mine).

i'm jumping off the good ship m$ and determined to make this work!

Ubuntu Networking :: Wireless Router Connecting ?

Jun 21, 2010

I have a computer running Ubuntu, and a MacBook Pro. I need to buy a decently cheap wireless router that I can hook up to my Ubuntu so that it will send wifi signals and I can use the wifi to go online with my MacBook Pro. I was about to get one today, but remembered how Ubuntu is picky about working with things like that. I'm only going to be using it to get signals around the house which isn't that big at all.

So what would be the cheapest and decently efficient wireless routers that I can use which Ubuntu will cooperate with?
