So I'm a Newbie and I've had Ubuntu for a couple months now and I've got to say I really like it. I haven't had that many problems with it that I couldn't find the solution for online. However, yesterday out of no where my wired internet connection just stops working. This is really frustrating because I'm getting an I.P. address but I'm not able to pull a page. When I go to network properties (from the panel) I see sent and received packets but when I go to configure it is says that interface doesn't exist. Now when I do an ifconfig it shows up with an i.p. the RX and TX packets look odd it says RX 1512 errors 0 dropped 0 overruns 0 frames and TX 110 errors 0 dropped 0 overruns 0 frames.Is that normal? When I try to do a sudo ifconfig eth0 up it says unable to resolve host. I have windows machines on the same network and they all work fine. My laptop worked fine too until yesterday. It might have done some updates since the GUI looks a little diffrent. I've been dealing with this for two days and there's no wireless where i'm at can anyone help??
