Can't connect to the Internet through my Ethernet port

[mattfett]

So I have the Pi up and running but can't connect to the internet.

I have the ethernet cable plugged into my router, but I don't get any of the lights on, and I'm not on the internet. When I bypass the router, and plug the cable directly into the Pi, the lights come on, but still no connection.

I had it working about a week ago, but for some reason, it doesn't want to work for me now.

Thanks

The Raspberry Pi is hardware and has no capability to connect to the Internet what-so-ever

Operating Systems do have the capability to the communicate, therefore at the command line prompt type ifconfig and post the output here please

I know the computer isn't connecting to the internet, so I'm thinking it's getting the port turned on?

Thanks

/etc/network/interfaces needs a dhcp line adding - probably set to manual at the moment

Code: Select all

iface eth0 inet dhcp

[mattfett]

I checked and it's in there, but still no internet.

Thanks

dump the contents of your /etc/network/interfaces in a message

also does your router do any MAC address blocking - usually its on wireless connections only but I suppose its possible for wired connections

[mattfett]

Sorry it's been a while, I sent that Pi back and got a new one. Here's what the interfaces file says:

auto lo

iface lo inet loopback
iface etho inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.config
iface default inet dhcp

Thanks

Check the power. I had a similar issue and switched from a usb/plug to plugging my USB into PC USB. Network has worked flawlessly since (granted, just a couple days).
