Using 10.04, everything working fine every day since the install a month or so ago. I shut down the machine normally, when I returned a few hours later it started up without a hitch, but without network. I found a thread suggesting the following (in the case of a failed suspend, which did happent to me a few weeks ago)
Code:
service network-manager stop
rm /var/lib/NetworkManager/NetworkManager.state
service network-manager start
but it didn't help.
My ifconfig looks like this

I'm clearly missing something small. My Ubuntu machine can see the XP machines in the WORKGROUP, pull files over and even print to the printer attached to one of them. Internet sharing also works. However, the XP machines cannot find the Ubuntu system.

I set up a Ubuntu Server for my home network to share among Win XP and Ubuntumachines.Initially everything worked fine with all Win XP machines being able to share files on the server; however, after I installed and setup SSH between my Ubuntu machines and my Ubuntu Server I now cannot share and/or even see my Server directory from Win XP or Ubuntu machines through the Samba.I have tried for 2 days to figure out the problem without success.Did I break something while setting up the SSH? How can I fix Samba?Here's some things I have setup or tried so far:1. Samba users are setup and were working previously.2. Samba share drives were setup and working previously.3. I can see the Server using SSH or SFTP from my Ubuntu machines.4. I have gone over the Samba config file numerous times5. I am administering Samba on the server via the terminal and Webmin

My XBMC box has been working just fine for a few months. I could easily browse to the Windows shares located on a machine running Windows 7 both within XBMC and Nautilus. However, now I can't browse to the shares using either XBMC or Nautilus (via Places - Network). Furthermore, when using smbclient in terminal I get the following error:
Code: smbclient -L fileserver protocol negotiation failed: ERRnomem.I have tried using the IP number as well (the host is entered in the hosts file.I can ping the machine just fine, using either the IP number or the host name, but the ability to browse its shares is impossible. I can access the shares using another Windows 7 machine, so the shares are there.

I've upgraded to Maverick but now I cannot get my wireless card working. In Lucid it didn't work out of the box, but worked perfectly by wrapping the Windows driver with ndiswrapper.
I noticed when I installed Maverick that wireless is enabled in Network-Manager and it gives me the option to create a wireless network or connect to a hidden network but it's not discovering/showing any of the wireless networks in range! So it seems as though the card is being recognized but the driver isn't working fully...? I tried wrapping the windows drivers, but that didn't change the situation at all.
Details of my system:
Code:
Ubuntu 10.10
2.6.35-22-generic x86_64
Code:
Desktop PC:
Intel Core i5 750

I just upgraded from 9.04 to 10.04 and so far I have those problems:
1. Before, everything in my system was in English. Now, half is in English, half in another language (PCManFM, some menus etc). I tried setting up Language Support but it changes nothing.
2. Cursor themes work only when hovering the mouse over "X" buttons in the right top corner of the window. As soon as I move the mouse somewhere else, it goes back to default cursor theme, even though I tried selecting 5 different themes - same result.
4. Hibernation don't work anymore. s2disk saves image to disk and then it resumes it but computer stops on text message along the lines of "Resume completed successfully".
5. Changing volume with keyboard shotcuts no longer works.
6. Smplayer does not display picture anymore when playing movies. The view is just empty. I can only hear the soundtrack. It is using XV filter.
7. PCmanFM that used to worked flawlessly, now after going into 1 or 2 subdirectories stops reacting to clicks on file/folder list. Need to open new instance to be able to do anything and this again would become unusable after visiting 1-2 folders.

I'm not sure if this is the right place for this. I'm not sure which veraion of linux I have but it was the latest veraon bfor the recent update. I accidentally hit alt ctrl f11 and my comp went inyo the grub menu. I've tried startx and it does nothing. About half the commands I enter do nothing and the other half r not found or are incorrect. The only vommand thw actualley work is reboot. I searched for this and read a grub guide but it did no good.

I've recently updated my ubuntu lucid to maverick (32bit).However I noticed a strange issue at boot. My boot time is increased more than three times(tried to reprofile, but with no improvement) from 24s to 1.23min.After some bootcharting,I noticed that the disk utilization during maverick boot seems to be at 50% for most of the time and also the cpu seems to work at half speed for most of the time...My laptop is an asus m51sn, intel t8300, nvidia geforce 9500m gs, 3gb ram, 500Gb WD scorpio blue hdd.
bootchart for maverick:

For some reason my network card started going 10Mb/s half duplex instead of 1000Mb/s full duplex. System is connected to 8x1Gb HP switch.Other devices connect fine through the switch and get full 1Gb network.I have Centos 5 with all updates. Driver comes from elrepo and as well is updated.

I had an Ubuntu Server 32 bit installation and everything was working fine. Now that I installed Ubuntu Server 64bit on a new drive in the same machine, the ethernet card is not working!! This is insane cause when I put the hard disk with the 32bit installation back and booting from it, the ethernet card is working without any problems but in the 64bits installation it is not shown at all using "ifconfig -a"
lspci output:
Quote:
02:00.0 Ethernet controller: Atheros Communications AR8151 v1.0 Gigabit Ethernet (rev c0)
How can I check which module is being loaded in the 32bits installation to try to load it manually in the 64 bits installation?

I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?

OK so I set up a server yesterday and got ndiswrapper loaded on it with the appropriate driver, I edited the /etc/network/interfaces file to contact my router with it's MAC address, WEP Key, etc... So the problem is I can ping addresses like Google and Ubuntu Forums but I can't use apt-get to install or update packages. When I try sudo apt-get update I get a whole bunch of Code: W: Failed to fetch <address>Temporary Failure resolving <address>My Wireless interface is wlan0 and also I can ping my server from my other computer running Linux and my server can ping that computer too.

I have a pretty decent DSL connection that usually gave me about 105KB/second download speed over wifi. The "official" download speed was 1.5 megabits so I should have been getting a bit more, but that's not my question.
I recently switched to Mint from Ubuntu. Now my download speed is significantly slower, to the tune of 45 KB/second. Since the connection runs at normal speed when I connect via an ethernet cable, my guess is that mint doesn't give enough power to the wifi card. Is there any way I can fix that?

I have just done a new install and have no network (LAN) connection.My network card blinks as if there is activity but the corresponding diode on my router is not active.I have checked the ethernet cable by switching with a valid connection to a WinXP system; like this I know that all the router ports are good.The network configuration module does not indicate a wired connection.
I have also tried sudo ifdown eth0 and sudo ifup eth0 but receive error message: interface eth0 not configured Can anyone help as it is my first experience with linux systems.

I have BroadCom BCM4318 802.11B/G Wireless Card. When I first started Ubuntu a week ago it didn't work, but I fixed it after a day or two of googling it. However I made a mistake and uninstalled the Network Manager. I then reinstalled Ubuntu, but it wouldn't load the card again. I activated the driver, and restarted the computer, but then, since It was connected via Ethernet, it wouldn't reconize the Ethernet connection, but the wireless card it did, but wouldn't find a network that is supported.

I have just recently installed Ubuntu karmic on one of my machines. The network worked perfectly until today, when it just wont connect. I have double checked that the SSID and Password are correct. It is a WPA network. I am sure it is a problem with my computer, not the network, because my brother's laptop (which I am using right now) has ubuntu 9.10 installed on it and the network is working perfectly.

I recently upgraded to 10.04 and now my wired network no longer works. I am unsure if it worked at all since the upgrade as that computer is rarely used, but it was definitely working prior to the upgrade. It is some sort of Realtec card, I believe. Does anyone have any suggestions? I'm running 32 bit 10.04 on a 2 GHz P4.

I use Ubuntu 10.04. Last night, I installed the most recent updates for this istribution, and before I shut off my laptop, my internet was working smoothly. However, today my Internet connection is behaving very strange. When I try to connect to the internet, my browser times out or cannot establish a connection. I'm able to connect to low-input sites like Google search, but I cannot connect to sites like Facebook, Wikipedia, or even the Ubuntu forums (I'm currently using a friend's laptop to post this). Pidgin and Skype work without a problem, as well as Transmission. I primarily use Firefox, but I also tried Chrome, Opera, and Epiphany; none of them worked. Oddly enough, my update manager also cannot connect to the Internet to retrieve updates.
I have restarted my router, but it still works properly, as it is running fine on my friend's laptop. I have tried 'no proxy' in Firefox, but it did not help. I also disabled IPv6 in etc/sysctl.conf by adding the code:
#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

If I click the network indicator and select Connection Information, I get a dialog that says "Error displaying connection information: No valid active connections found." If I click Edit Connections, it shows Auto eth0 as "Never used". Yet I am using my network connection right now. If I download something, I am getting full performance. I am surfing the net and posting this, now.What has happened to my connection info and how can I fix it?

I have a wireless network using this driver:
Bus 001 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
and everything works fine for some time. After a few hours or maybe less (if I push bandwidth to the limit) the Internet freezes. I can't even ping my router. If I disconnect and reconnect either the device or the connection via network manager , it does work for a minute only and then freezes again. If I restart Ubuntu entirely, it works again. But for a while...
It works 100% in Win7 and I have no problem at all there. But I am very annoyed that I cant have reliability in Ubuntu. I want Ubuntu as default.
It has something to do with drivers or an inner variable or buffer or something.
At least, is there any way to reset my network connection without rebooting the OS?
I tried sudo /etc/init.d/networking restart but it gives me: Ignoring unknown interface wlan0=wlan0.

Let me start off by saying everything WAS working...I have a lab environment comprised of two subnets (.1.128/25 and .2.0/25). On the .1, I have 3 Solaris 8 servers running NIS, NFS, databases, DNS, various services, etc... the network was setup on VLAN'd Layer 3 switches with the VLAN interface addresses acting as default gateways (dgw) for the two networks (on a single switch). The switch dgw was a router for outside connectivity. The servers are running ODCS OpenSSH.I was having problems with the VLANs, so I reconfigured the network so that each subnet had it's own switch as a dgw, and they route through a point-to-point static route setup as 192.168.0.1&2 on a separate VLAN between the two gateway switches.Here's where the problems start:First, ALL the services (NIS,NFS,databases,DNS,etc) are STILL WORKING. I can ping all the addresses. Traceroutes show the proper path thru the point-to-point, etc. There are NO firewalls setup, hardware or software, network or host-based... no iptables running, etc.
The three servers are on the .1 network. I can ssh to them from hosts on the .2 network no problem. However, I cannot complete an ssh login to them from any host on the .1 network. I get a password prompt, enter the pwd, and then it hangs until I receive a "Connection timed out" error message several minutes later. The next time I log in however, it shows "Last successful login" from the failed attempt.While the connection is hung, netstat on the server shows "ESTABLISHED" to the client on the proper port. nother odd indication is that I CAN sftp to the servers from hosts on the .1 network.
