Ubuntu Networking :: 9.10 On Lenovo S20 Netbook Network Stall
Feb 6, 2010
i have searched the forum but can't find the solution for stalling network in the middle of something. i have to restart the computer. i cannot rely ubuntu for 24 hours non-stop small server. the stalling problem occurs when I start pulling/downloading via samba or sftp (smb:// or sftp://) from another computers/device (like wdtv). when i check the lenovo, all internet connecetion is dead. ifconfig shows the ip but it just dead.

I just installed Netbook Remix 10.04 on my Lenovo S10 netbook and wireless is not working. I looked on google for some answers and saw that the Broadcom STA driver may be missing so when I tried to install it through Synaptic Package Manager it said that it was already installed. When I click on the wireless icon, it says under wireless that the device is not ready and I can't connect to any wireless networks, even if the SSID is not hidden. I am confused as I already have the driver and all the system updates but it still won't work.

I just got a new T400 and installed Ubuntu. Everything is fine and I'm really impressed by this OS. But seems my wireless network is very unstable. Sometimes it just can't connect.
The wireless interface is:

Two month ago I bought Lenovo S-12 (netbook) - [URL] Everything worked great at the beginning. In the last month I have problems listening to music, it stops and continue once a second. I made a video to show how it goes: [URL] This problem happens also in ..... and any other online website.

Trying to debug a network issue - we have problems with scp transfers to a remote host intermittently stalling. I believe it may have something to do with incorrect handling of sack / dsack TCP options. Looking at netstat -s, during a (successful) scp transfer the TCPSACKDiscard and TCPDSACKIgnoredNoUndo counters increase rapidly. This is on the client initiating the transfer to the remote server. This doesn't seem normal, but I'm having difficulty finding an explanation of what exactly these counters signify. The tcp_sack / tcp_dsack / tcp_fack options are enabled in the kernel on both hosts.
How do I debug this further? Are the counters a symptom of a known problem? It's kind of hard to google this, all I get is unrelated netstat output which happens to include 1 or 2 discarded SACKs, not tens of thousands like I am seeing. I can make tcpdumps on the client (unfortunately not the server), but what should I look for?

I decided to try ubuntu on my netbook and it seems to have set up well other than I cannot see any wireless connections. I can't click on connection information. The blue light is on, indicating that my netbook's network card is on.
is there another version that would work better with an hp mini? Otherwise the netbook is rather pointless

I got my netbook in the mail yesterday, opened it up, logged in, and Windows 7 was installed. Being a Windows hater my whole life, I followed a friend's advice and downloaded Ubuntu netbook, made a USB drive, changed the BIOS settings, all that. Here's when the stupidity occurs--I decided to go ahead and install Ubuntu without trying it, and to delete Windows to do so. A couple minutes later I realized that was a really, really stupid idea, so in a panic I turned my netbook off. I turned it back on and it was still on install but not really moving, so I powered off and on again and went back to the "Try Ubuntu" or "Install Ubuntu" choice screen. I chose "Try Ubuntu" and found that it did not recognize my home wifi network or ask me to join--or any wifi network, for that matter.
Now, it did recognize my wifi network the few minutes I spent on Windows 7, so I tried to change the BIOS settings back to where I could just use that until I figured out the problem. But no matter which setting I tried (HDD/SDD just gives me a black screen, and FDD and LAN do the same as the USB drive), I can't get back to Windows, so I guess I did delete it. Which leaves me with a netbook that can only connect to the internet via ethernet cable. Which kind of defeats the purpose.
Questions I should answer:
1. How am I trying to get online? My home's wireless network. We have a router. All the other laptops in the house connect fine.
2. Who is my internet service provider (and in which country?) COX, United States.
3. Can you get online with any other method? Yes, the internet works fine with an ethernet cable.
4. How am I getting online to post in this forum? My parent's laptop.
5. What hardware are you using? Toshiba N505 netbook and a router. I can give more information about the router if you need it, but I doubt it's the program since the other laptops are fine.
Give me one moment and I will add some code that it gives me when I put in the commands this website tells me to.My two final questions are:
1. Is there any way to recover Windows without buying it again?
2. How can I get Ubuntu to connect to my home wifi network?
EDIT: Here's some code. I have no idea what it means, but hopefully you do.
To run a command as administrator (user "root"), use "sudo <command>".See "man sudo_root" for details.

While installing the openSuSE on my Netbook (Acer AspireOne D250) with a bootable thumbdrive Live image, the installation seemed to go fine, but after the installation was completed, there was no "network"! I checked and the system auto-sensed the drivers, but when I go into the network, even trying to manually set up the IP info, Yast reports NO NETWORK running!!
I then went out and bought a USB CD-ROM drive and installed using the boot CD (Network install) on the external USB CD-ROM drive. It booted up fine, and installed "RIGHT OFF OF THE NETWORK", but when the install was through, I could not access the network. Same error: NO NETWORK RUNNING!! Now I've installed openSuSE on this unit before (v11.4) and it worked fine (after I changed the wireless driver to the legacy driver) but this time it's NOT working!! My 13yr old son uses the Netbook, and was so excited to get to use LINUX instead of Windows ... until now.

I have just purchased an Asus EeePC 1001HA netbook and I would like to install Ubuntu Netbook Edition 9.10 (love the look and the brilliant interface), but I can't get the wireless network to work. I am currently running from a 4Gb USB stick that has the LiveCD on it with a 1Gb persistence. The network notification area only shows wired and VPN connections. I have tried installing the Ralink 3090 driver but I have had no luck in getting the wireless to work.

I like to watch DVD's from netflix etc on my laptop. I've tried VLC, Mplayer, Movie Player and Xine and all of them do the same thing more or less. The movie plays but it pauses or lags every 3-6 minutes or so, then resumes. VLC seems to work the best, but it does it too and it's to the point where it is irritating to watch a movie on it. You watch 10 minutes, then a freeze, VLC says "buffer.." and runs from 0-100% in a little progress bar, the DVD drive spins up again furiously then the movie plays again. Over and over through the whole movie.
It does it in EVERY DVD I have tried. I've tried everything from completely uninstalling the movie players, reinstalling them, tweaking every setting I can find per instructions I've found on other forums. I even went as far as going into my laptops BIOS to set the CD drive speed to HIGH.
Is this just how it is watching a DVD on Ubuntu or what? I really do NOT want to resort to reinstalling Windows 7 (ugh) but this is unacceptable. I'm open to any and all suggestions on how to get acceptable, reliable performance out of one of these DVD apps. Not sure what info will be relevant but, the machine is a brand new Lenovo T510 thinkpad, Core i5 2.4 ghz, 4 gb RAM, Nvidia graphics. Running Ubuntu 10.04 32 bit.

I'm surfing along just fine when I select some link in my browser.The status line reports "... waiting for ..." and the browser seems to stall for a long time (minutes). Often, but not every time, I can select the STOP toolbar icon and reload the page. This time things work normally.
I have a similar but different malfunction running Evolution email connected to my hosted IMAP server. I select a message and see "... formatting ..." and then Evolution seems to stall for a long time (minutes). Rarely the stop-reload actions help reading email. Instead,all Evolution windows go dark grey and the entire desktop stalls.[Analysis -- It has the feel of a "network" issue provoking issues within Evolution itself rather than an Evolution-only malfunction.]
Watching the running system with 'htop' and similar, I do not see where some other application or service is sucking all of the available CPU time or such. [Analysis -- It has the feel that either the browser message or the email message were sent into limbo without reaching their intended destination. Stop-reload sends the bits to the right places and so I get results.]

I recently got a lenovo w510 laptop and I installed openSUSE 11.3 KDE on it. the wireless works fine at home (802.11g WPA2) when I go to work I have tried to set up the wifi for the 802.1X PEAP network but it doesn't look like it even tries to connect.
The work network set up is as follows. non-brodcasting SSID (do I need to tell network manager of this? I manually enter the SSID no problem)
Dynamic WEP 802.1X
PEAP
blank anonymous identity
no CA cert (I suspect this might be the problem)
PEAP v 1
MSCHAPv2
I have verified my username and pw several times, as well as the SSID. Just yesterday I helped a co-worker get on the network under ubuntu and it worked like a charm.
The Hardware profile displays the wifi card as a "WiFi Link 6000 Series" It is an intel card.

I've blacklisted acer-wmi as that was the fix previously, but that has no effect.
When I do an rfkill list it tells me brcmwl-0 is hard blocked, regardless of where the hard switch is. The hard switch is working fine for the bluetooth..

I have a relatively new server (Ubuntu Server 10.04.1) with a "/backup" partition on top of LVM on top of an MD raid 1.Everything generally works, except that it freezes during the fsck phase of bootup, with no errors. I've given it 20 minutes or so. If I press 's' to skip an unavailable mount (documented here), it reports that /backup could not be mounted.here are no LVM related messages in /var/log/messages, syslog, or dmesg.
When I try to mount /backup manually, it reports that the device (/dev/vg0/store) does not exist. Apparently the volume group was never activated, though all documentation seems to claim it should happen automatically at boot. When I run "vgchange vg0 -a y", it activates the volume group with no issue, and then I can mount /backup./etc/lvm/lvm.conf is unchanged from the defaults. I've seen posts mentioning the existence of a /etc/udev/rules.d/85-lvm2.rules , but no such file exists on my server, and I'm not sure how I would go about creating it manually, or forcing udev to create one.There are some open bugs describing similar problems, but surely it doesn't happen to everyone or there'd be many more[URL]

I have been using Ubuntu at my home laptop (Dell) have had no problem. However, recently I installed 11.04 in my office laptop - Lenovo B450, but 'm unable to connect thru wireless.
It is simply not detecting the wireless. I have a dual boot with Windows 7. Windows 7 detects wireless (surprisingly).
I have tried configuring the network connection in all possible way (manual / auto).

I installed Ubuntu 9.10 on my Lenovo T500. The wireless interface information is listed at the bottom of this message.I would like to connect to my Airport Extreme wireless router which is password protected. The bottom of the router lists three MAC addresses with different symbols next to them. I assume the symbols mean different types of connections (e.g., firewire, ethernet cable, etc).
The network icon on the upper right corner of the screen indicates that wireless is enabled. However, I don't get a wireless connection. I checked that the switch on the front of the laptop is "on" for wireless.

I installed Ubuntu Netbook Edition on my Lenovo IdeaPad S10 yesterday (I was using Window XP before that) and since then I am struggling to connect to the internet. I think the wireless network device is on because Bluetooth is on and there is a reassuring blue light near the wireless symbol. But the network managers says "device not ready" and don't find any wi-fi spot.I've read posts on the subject and followed the instructions from the official documentation.

Tried the normal fixes and installed the wrapper, etc. Wired network works fine, and I am able to access some unlocked wifi networks from neighbors, but I cannot access my own password protected network. It just keeps asking for the password and never connects. Fairly new Ubuntu guy here.

Im using natty in lenovo b460. After installation was not able to connect to wifi. Ethernet is working alright. So searched for additional drivers and installed the Broadcom 43xx drivers. After restart the network applet says the wireless is disabled by hardware switch, even after it is switched on/off several times.

I tried the Googles praised Chromium browser and while it seems to render pages fast enough and has a really nice interface, I experienced an annoying responsiveness problem. Opening a link in a background tab seems to stall the browser almost completely until the page has been loaded and rendered. For example scrolling the page that I'm currently viewing becomes almost impossible. The same actually applies to the current tab too, of course. If the page in the tab hasn't been loaded completely, scrolling is really really clumsy. I tried disabling the installed extensions and also tried experimenting with some command line options, but no help there.

what is really a rant disguised as a question, but does anyone have this combination working? My NetGear router shows the connection as allowed from the MAC address in the router logs, And I can see the network I want to join in the list of visible networks from the laptop, but dmesg shows Ubuntu disconnecting with
WPA-PSK [TKIP] only:
wlan0: disassociating by local choice (reason=15)
WPA-PSK [TKIP] + WPA2-PSK [AES]
wlan0: disassociating by local choice (reason=3)
I'm sure there is a simple explantion that has been sufficiently buried somewhere but after several hours of googling and searching the forums here I can't find it. Anyone want to help out an old man RTFM?
I'm getting really disappointed here lately - things are getting worse, not better. In my case in particular I have this laptop with supposedly open and supported drivers and they don't work, however, the exact same distributuon on a Dell D830 with a broadcom NIC does. under 8.10 and 9.04 this worked out the box - just logged in, gave the PSK and away we went. I can't see the attachment I just uploaded so to include the information requested in the "how to get help" post, I'll put it all here inline...
