From what I can tell, you have a wireless network with resources you need to access from your desktop. See this tutorial: https://help.ubuntu.com/community/NetworkConnectionBridge The easiest would be to make a bridge(laptop): apt-get install bridge-utils brctl addbr br1 brctl addif br1 eth0 brctl addif br1 wlan0 ifconfig br1 up dhclient -4 br1

Now, click on network-manager icon on the laptop and select edit connections. Click to select the wired connection and then click edit. Click on the ipv6 settings tab and change the ...

Here are some possible options and alternatives I can suggest: Download the driver on Windows machine, save on USB, transfer to Ubuntu, install that driver with sudo dpkg -i package-file. Boot that Windows machine with an Ubuntu Live CD or USB that you used for installing Ubuntu (hopefully you still have it) and use that live desktop in as wifi to ...

Another solution, using udevadm udevadm info -a -p /sys/class/net/eth{0..10} | awk '/device.*eth/' {0..10} – checks the initerfaces from eth0 … eth10 Therefore you could use this command pci_address=$(udevadm info -a -p /sys/class/net/eth{0..10} | awk -F/ '/device.*eth/ {print $4}') Example output looking at device ...

lswh and lspci bot are capable of showing that information.As you have found out already, you can do lshw -class network -businfo. For instance, here's my output: $ sudo lshw -c network -businfo Bus info Device Class ...

It looks you can tie them together by the IRQ. ifconfig -a will print the ethernet devices including Interrupt. eg. eth2 Link encap:Ethernet HWaddr 00:25:11:19:8b:77 inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::225:11ff:fe19:8b77/64 Scope:Link UP BROADCAST RUNNING MULTICAST ...

Okay I solved the problem with this commands: ip link set dev eth2 down sudo dhclient eth2

You can try to install another driver for this Ethernet card sudo apt-get install r8168-dkms If that does not help, check the cable, contacts on both sides. Expanaition Realtek Ethernet RTL8111/8168 adapters are generally supported out of the box by Linux kernel. There is r8169 module for that. In most cases it works well. But some hardware revisions ...

This is Ubuntu bug 1438003 and it has a workaround: I'm hitting this bug too, and so far working around it by going to Edit connections → Edit the network you want to connect to → manually input the WPA2 password in the Wi-Fi Security tab → Save, then it connects without problems.

You can't have the same IP, but you can just have both interfaces active at once and set up a script to try to determine if the wireless connection is up, then use that. Then if it's not up, default to eth0. But if you've already got a cable run. why use wifi at all? Ethernet is much faster/more reliable/all around better than USB wifi...

I have been endlessly trying to find the best solution of upgrading the Wi-Fi Ubuntu 14.04.2 LTS drivers on my 2014 13.3" MacbookPro Retina and I have tried every possible solution - going onto different website and trying to install from the boot drive, or trying to get all kinds of files which would mimic the files described by the gentleman above. The ...

i actually had the same issue as i was fixed on the old ethX naming scheme and trying with emX / ethX combinations as you did, you get with "sudo lshw -C network" the network card details .. in my case *-network:0 DISABLED description: Ethernet interface product: 82599ES 10-Gigabit SFI/SFP+ Network Connection vendor: Intel Corporation ...

I arrived at a solution after watching the following video: https://www.youtube.com/watch?v=yqJ9PXhqOAQ Launch Network Connections, e.g. by clicking on the network icon at the upper right and choosing "Edit Connections..." Select the "Wired connection #" corresponding to the Ethernet port that will be connected to the switch. Choose "Edit..." Under the ...

Couple quick searches tell me that the VIA chipset and the Killer (Qualcomm cihpset) should both be supported on newer kernels. Your LTS version should get backports, but that depends how old your images are(just checked, current LTS is 14.04.2 and 12.04.5). I'd be curious to see if it's fixed in a newer kernel. From here ...

Yes, but more than 1 line does not mean more than 1 NIC. Example $ lspci | grep -i net 01:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5716 01:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5716 This is 1 NIC connected to eth0:0 and eth0:1 (so 2 IP adresses) that is a PCI device(!). There is a better command: ...

lspci list alll PCI devices so if you have some old built in network card, or some usb cards it will not shown in the result, so to get more precise result try this: ifconfig -a | grep Ethernet Thanks for @gertvdijk note add the -a option to ifconfig to list all interfaces even if they are down

If you want a little more detail try jnettop this tool shows you detailed traffic monitoring in the terminal. sudo apt-get install jnettop once installed simply type jnettop in the terminal

I agree with @Shauna, but, if you want to set your system up so that wired and wireless are never on at the same time, and, if you are command-line literate, read man 5 interfaces, especially: IFACE OPTIONS The following "command" options are available for every family and method. Each of these options can be given multiple times in a single ...

It is well documented that, despite Broadcom's README, bcmwl-kernel-source does not work for your device. I suggest you do: sudo apt-get purge bcmwl-kernel-source sudo apt-get install --reinstall firmware-b43-installer sudo rm /etc/modprobe.d/broadcom-sta-common.conf Reboot and your wireless should be working.

Your Ethernet adapter looks OK. But the problem is that you have connected wired and wireless interfaces at the same time. That confuses routing. If you disable your wireless interface, network should work OK.

Your probably running into the same issue I am. Please help rally the devs to fix it. See Bug #1472055. -Cheers, Peter.

You can't have two gateways configured on the same device. You don't need a GW for eth0. --DHCP and NAT I used https://codeghar.wordpress.com/2012/05/02/ubuntu-12-04-ipv4-nat-gateway-and-dhcp-server/ for my setup and it works fine. --Boot on LAN I recommend using etherwake and PXE server. Hope it helps...
