How do I un-clone the MAC address on my NIC? This is driving me NUTS!
Using network manager I cloned a mac address (to try and sort out some network issues).
So I've been trying to use a laptop who's wifi card doesn't work properly, by using a Lenovo V570 laptop with Ubuntu 12.04 to bridge the two networks. I changed my ethernet network to "Shared to other computers" through Network Manager, but it still refuses to work.
I believe the issue may be in my /etc/network/interfaces, as I did edit it at one point and forgot to make a backup.
I just setup internet connection sharing with the network manager on my laptop with ubuntu 12.10 and a wireless internet connection on eth1, so that it is sharing the connection through eth0, an ethernet port.
It works, but the ip address given to the client (another ubuntu 12.10 machine) is 10.42.0.67.
How can I change this?
I have setup internet connection sharing manually before, with ip masque
I'm rather new to Linux/Ubuntu and about to lose my religion figuring this one out.
I am unable to connect to the internet with ethernet in 10.04 64bit. Everything was working fine this morning, but when I booted up this evening, no connection.
In Network Connections, under the Wired tab, Auto eth0 reads Last Used: never. Also, Network Manager had created a new network, Wired Connection 1.
I am using ubuntu 10.04 (Bio-linux 6.0). Last night I tried leaving my system in hibernate mode because there appears to be a bug in this version of ubuntu such that if I do a straight shut-down, the machine will boot up by itself some time overnight.
This morning I could not bring the system back up from hibernate so had to hold down the power button to reset.
Ethernet suddenly won't work
Hi,
I've recently got som problems with my ethernet connection. Ethernet have always worked before, but when I moved to a student housing I had to configure Network Manager to make the new ethernet connection work, so I did and it worked. But now, when I use ethernet connection other places than in the student housing, it won't work.
I am on Ubuntu 12.04, 64-bit, fresh install. I have a wired connection (eth1 interface), the IP address is assigned by DHCP, and PEAP authentication (wpa_supplicant) is set up.
My problem is that network does not start at boot. I have to log in without internet connection, and then I have to start network-manager manually (sudo start network-manager).
I've been struggling to connect to my home wireless network, but up until now my Broadcom card has been able to at least detect the network. I know this because in Network manager, in the Add Network Connection dialog box, if I tell it to scan for wireless networks then I see my home network along with all the other local wireless networks.
I want to avoid any password prompt from Ubuntu (12.04) network manager. I just want that the application works silently with the network and password that I gived to it and prompt for password just if I clicked on connect, but no automatically. The problem is that sometimes when the connection fails for any reason (bad signal for example), the network manager ask again for the password.
