Since you now have an interface listed, can you ping anything? Can you ping itself?<br><br>If the IP is statically set in /etc/network/interfaces, rebooting certainly wouldn&#39;t hurt, but it shouldn&#39;t be any different than stopping and starting the interface. If you want to go a step further, do &quot;/etc/init.d/networking restart&quot; instead.
<br><br>Afterwards, check the results of ifconfig eth0. If the listing for the interface is ok, then try and ping the gateway IP. If that is successful, well you&#39;re in business and I would look to your DHCP server. The DHCP on my linksys has stopped working a couple of times over the past few years...power cycling usually fixes this. Or it could be as Jeremy suggested.
<br><br>If you cannot ping anything on your network, then try and ping the IP assigned to the interface. If you cannot ping that (eth0 not lo), then there really is a deeper issue.<br><br><br>
