Wired network is connected & acquires IP address but the internet is not working

Question

So the other day when my network died completely without a warning at first. I thought it may have been the modem or the router (the modem can't handle to many connections as its a a bit dodgy); but neither was the problem.

I had to re-install Linux system due to a messed up graphics driver (it was my fault which I did something totally wrong and couldn't get it to work again). But my wired connection will not connect to the internet. I do have an IP Address, Submask, IPV6 address and the light on the Ethernet port at the back is transmitting data with green & orange LED's, also my WiFi connection still works perfectly.

I've posted my inxi output, syslog & ifconfig. If there is any one that can advise me a with this, that would be awesome.

Solution

You can statically set your IP address by doing this -

• Go to folder /etc/network/

• You can see a file called interfaces

• Just make a backup copy of it somewhere safe and open in gedit

• Originally the file may contain following

  auto lo
  iface lo inet loopback
  

• Now add the following things to the file

  auto lo
      iface lo inet loopback
  auto eth0
      iface eth0 inet static
      address 192.168.1.108
      netmask 255.255.255.0
      network 192.168.1.0
      broadcast 192.168.1.255
      gateway 192.168.1.1
      dns-nameservers 8.8.8.8 208.67.222.222
  

• Enter all your required details and save the file (all above details are examples)

• Now restart your networking service by typing following command in terminal

  sudo service networking restart
  

• Note : For wifi you just replace eth0 by wlan0

[AzkerM]

As in your question, you mentioned that WiFi works. Does that mean you're able to browse internet too?? Also, could you please try restarting your network manager first with sudo service network-manager restart & let us know whether that helps! :)

[user1990312]

Yes I can browse the internet on WiFi but not on my ethernet connection this is what is confusing me if I run sudo service network-manager restart, I have to reboot the machnine as the network manager doesn't come back up, I'm starting to think this may be a problem with my ethernet port rather than linux.

[user1990312]

After trying the above all I get is an unmanaged device and I've tried editing it via the network-manager by adding a new wired static connection but I get an error "(32) Connection Could Not Be Found" if it's a static connection.

[AzkerM]

I would not recommend adding static IP's as the questioner is able to acquire IP address at initially. Revert back your interfaces settings to its default & try my comment. Also please post the complete output of ifconfig -a :)

[user1990312]

Here's my teamviewer id & pass as I am completely stumped with this the internet works just not with a wired connection ... ID: 837 279 085 Pass: 7729

it looks like you do not have a default route configured. Wht is the output of route -n when connected via ethernet
