I am working on ubuntu 10.10 in a VM. I went ahead and did updated the system when prompted. That has disabled my wired network connection. I am not sure what is the reason. If it is a device driver or any network service. I guess device driver is not an issue as I can detect my network card from ubuntu.
Does any one know the solution?
Background infoMy laptop (MySN MG6.c) is dual-booted with Windows 7 and Ubuntu 9.10, and connected to the internet through a router (Digitus DN-11004-O), which is set-up to use DHCP. The internet connection works fine under Windows, and my previous laptop, which also ran Ubuntu 9.10, had no problems connecting to the internet through that router.The network adapter is an Atheros AR8131 PCI-E (also detected as Attansic under Ubuntu)stem infoResults from running various diagnostics (I have removed the output that relate to the wireless connection, as I don't use it):

Okay, a couple of weeks ago I was running 10.04, got an auto update that needed a firefox restart, so rather than restart, I just shutdown the computer for the weekend. When I booted the computer on Monday it would find sites (www.google.com, start.ubuntu.com) but it wouldn't download the necessary items to load the page. Now I have a windows laptop sitting next to the ubuntu box and it was online with no issues, so I know it wasn't the connection itself. So I decided that the update messed up the system so I downloaded 10.10 and installed that and ran that all last week.
On Friday I got a system update that required a firefox restart, so I ran firefox for the day and decided that since it was friday, I would just shutdown the computer and reboot on Monday.Well now Monday is here and now I again have sloooowww internet, to the point that URL.. times out and won't come up. I have tried doing a traceroute on both machines and the windows box gets all the way to www.google.com, but the ubuntu box gets about halfway there and then gets no response. I am at a loss, I don't want to reinstall every week. I did try to reboot and run the previous version of 10.10 that shows in the boot menu, but that does the same thing. One thing I did notice is that the broadcast ip is different than the machine IP, don't know enough to know if this is a problem.
My connection manager shows wired connections and shows wireless as being disabled. here is some terminal info getting wireless going?
Here is a bunch of things I have tried and the results.
nixon@nixon-desktop:~$ sudo ifup wlan0
Ignoring unknown interface wlan0=wlan0.
nixon@nixon-desktop:~$ sudo ifdown wlan0
ifdown: interface wlan0 not configured

I have the problem with my notebook, that, after I used it at work, the network-manager always tries to autoconnect after boot. He has no cable network and so I get the message "not connected" after a while.how to tell the network-manager, not to autoconnect each time?
View 4 Replies View RelatedI've installed Fedora 13 on a Toshiba Satellite A40 laptop, and am trying to get the wired ethernet connection to work. Network Manager says it is connected, and the connection details (DHCP assigned IP, gateway, dns servers) all seem correct. However, I cannot browse the internet. Checking for updates fails also. I have tried pinging various sites and the results are inconsistent - sometimes it works, sometimes it times out with "unknown host". [URL]... I've searched around for similar issues and tried disbaling ipv6 both in Fedora and Firefox, but this doesn't help either.

I'm having network problems and I have no idea how to fix it. At first, my internet connection was suffering on all computers on my network (Mac, Windows and Ubuntu 11,04). So, I disconnected my cable-modem and then reconnected. Nothing.... So, I rebooted my Windows machine and the internet came back on that computer.
I then went to my Ubuntu computer and clicked on "auto eth0" (per the way I interpreted instructions from the internet). The symbol turned from the "two arrows" to what looks like a wireless, looking for a signal. I thought that maybe I should just reboot, as I did with Windows. However, when I did reboot, that same wireless symbol was there, then a message came up saying:
Code:
Wired Network: You are now disconnected
I can't seem to get my internet connection back on my Ubuntu computer, though it is working on every other computer on my network.
i installed linux at home on my laptop (dv2000, hp). Because i was having problems connecting to the internet through wireless. And wired at friends houses.So installed linux. Wireless took me a while but finally got that working. Now the problem i have is that wired is not working apart from at home. Any other router apart from mine it cannot connect to.

I'm really in newbie category, and not comfortable with computer or internet jargon. I can still connect with ubuntu 8.04 and firefox, just once daily. In a later post I also added: In Ubuntu 8.04 there was a system> admin> network tab (missing in 10.04). In the connections tab "wired" was checked. The general tab had my computer name (tsq-laptop) for host, and a blank box for domain name. The DNS tab had 192.168.1.1 in the servers box (presumably my service provider BSNL), and nothing in search domains. The hosts tab had a list of IP addresses and aliases, the first few being:
127.0.0.1 - local host
127.0.1.1 - tsq-laptop
::1 - ip6 local host ip6 loopback
fe00:: - ip6 localnet, .... (and a few more such I think most (or all) of these entries were generated automatically by the system, since I don't understand the jargon at all! I don't recall having any difficulties then, some two years back.Before that I had major problems in using the internal modem for a dial-up connection, but got detailed help by e-mail/internet from some really knowledgeable people in Europe and elsewhere regarding linmodem configuration, which I followed blindly and it worked!
In 10.04 there is only the taskbar icon to edit settings, and it has a different structure. It asks for MAC address (example 00.11.22.33.44.55). Other info required is IPv4 settings, DHCP client ID, about routers and other stuff. There may be other system settings to be made, which I can try with proper guidance. The ubuntu help page gives very sketchy information, and the images are not clear at all. No response to that till second day. Subsequently: In the 'wired' tab the 'routes' button popped a table where I entered address as 127.0.0.1, and netmask as 255.0.0.0, leaving gateway and metric blank. This is all geek stuff for me - I'm an old-fashioned engineer from the slide-rule era!
Should all this have been in the newbie forum? Thanks, =TeeSquare=

I just installed ubuntu on my d620.The wireless card seems to exist and looks fine but I don't know how to turn it on.It says the network is disabled everywhere I look but I can't find the option to turn it on.I know this is probably simple. Below is the output from various commands.I included my service tag which you can use on the dell site to find specifics about my hardware.I can't do ifconfig wlan0 up which is the only solution I've found online so far.
View 7 Replies View RelatedI have a weird problem that I can't find the answer for in the forums or docs. I can see the wireless network in Network Manager, but it is grayed-out and inaccessible. Other wireless networks are white and I can click on them and connect to them (or could if I knew the password).
My work computer, an IBM ThinkPad T43 running Win 7, connects.
My personal computer, a Dell Latitude C640 running Ubuntu 10.04, sees the network as grayed-out and therefore I have no option to connect to it.
I have tried the following:Checked for hardware drivers - the system says "No proprietary drivers are in use on this system"
Verified that the network security settings are the same on both my work and personal computers: WPA2-Personal
Why can I see the network but it is disabled/grayed-out?
I accidentally removed the dhclient3 file. I had ran chkrootkit and it said it was a possible suspicious file. Once I rebooted, the network was disabled. I am running off the Ubuntu cd by choosing trial. How can I get dhclient3 back onto my installed Ubuntu?

I need to have a laptop that will try to connect as sson as I plug the ethernet cable in or as soon as it senses a certain SSID or as soon as there's a mobile broadband device plugged into a USB port. Non-system connections are working but I am not willing the actual user (non-admin) to read the WPA2 key or the SIM PIN. But the check box for the system connection is disabled. And running "sudo kcmshell4 --icon networkmanager kcm_networkmanagement kcm_networkmanagement_tray" doesn't result in a system connection.

I was using my usb Alfa AWUS036H-v5 usb wifi card, and then after I rebooted, it randomly stopped working.. did some searching on the site, one idea was to do
Code:
sudo lshw -C network
which I did, and it shows my internal wifi card (iwl3945) working fine, but says my wlan7 (Alfa usb) as:
network* Disabled
Also, in the upper right hand corner, the antenna is greyed out and says "Device Not Ready"
I'm having a problem where the wired network wired network (eth0) disconnects when the connection is idle for a while (usually tens of minutes). It works fine every time I boot up, but eventually it dies, and I can't ping the machine, or ping anything from the machine. ifconfig shows that it still has an IP address. Running ifdown/ifup causes it to work again. I intend for this machine to be a server, so I can't afford to go restart it when I need network access. sudo lshw -class network gives me this:

Both laptop and ps3 have static ip addresses
The reason for this is I can connect to the internet on my ps3 through my laptop, and I can stream from my laptop to ps3 through wired connection. This works fine in windows 7 all I had to do was right click bridge connections. As I dual boot I don't want to have to make any changes to the settings on the ps3.
My interfaces are:
eth0 - wired
wlan0 - wireless
I installed bridge-utils and created a bridge and added both eth0 and wlan0 to it. However I could not get it to work. I have also tried internet sharing through network manager and firestarter.
