hello all
i have a wired connection thru a netgear router wgr614, i am running a window machine fine , but ubuntu machine say no connection . i have look around seems to be a common problem . but no simple fix . Network manager is bad , do i uninstall or change thru terminal or ...... lost pls help
Tks anthony
How are you trying to make a connection? (There are several ways.)
Is this supposed to be DHCP or static?
Have you ever been able to connect - say with a previous Ubuntu 9.04?
What is your ethernet card?
Googling around, most problems with this card come from the ethernet card needing extra firmware.
yes i could connect with 9.04 , when the upgrade came no connection . the router see the machine just no connection. DHCP. From googling around i have found that the net manager is bad. So i am looking for what to do next! Is it nesecary to have the make and model of net work card?
it's always better to use CLI for system tweaking.
try to disable network manager and type dhclient eth0(or whatever your interface name is) from root and see if connection will appear.
Is it nesecary to have the make and model of net work card?
No - it is normally of no use at all to know the make and model. Instead, you need to know the chipsets. To find out, enter
lspci
into a terminal. This will provide a lot of output. Find the line that talks about a network adapter and copy it to your reply.Also show the output of:
ifconfig
Note: network manager is almost never the problem for this sort of thing.
If you right-click on the network manager icon, there should be a check-box called "enable networking" - is it checked? There is also an option to configure network connections - have you used it?
Sometimes Windows will leave a network card in an unusable condition (it assumes that it is the only OS on your system). You may need to wake it in windows first. Possibly if you power off the computer totally, wait a bit, then boot right into linux, the card will become available.
If you are using DCHCP on your router, just try entering "dhclient" as root from a command line. The eth0 interface is there, it just is not getting connected to your router.
If you had a fixed IP address prior to upgrading, you may need to re-configure this in /etc/network/interfaces. You may need to disable Network Manager to get these configuration settings to stick.
You needed to run dhclient as root. In Ubuntu, you run commands as root by typing 'sudo' and then the command, then you will be prompted for your regular password (unless you already used sudo in the last few minutes).
You probably don't need to go that far - if you right-click on the network manager applet, you can edit the connection information.
Simon excuse me for being a newbie, i typed what you posted. and got the following.
daddy@daddy-desktop:~$ sudo /etc/dbus-1/event.d/26NetworkManagerDispatcher stop
[sudo] password for daddy:
sudo: /etc/dbus-1/event.d/26NetworkManagerDispatcher: command not found
