We can rule out the ISP, the router, any switches in the way, any cables and the NIC because another OS works on the same hardware. What's left? - firmware for the NIC loaded at boot time - kernel recognition of the NIC - IP address (via DHCP? static?) - routing - DNS Testing some of these will rule out others if they succeed. Skip to the ping check at the end, and if it doesn't work, let's go from the bottom up: ip link show If this gets you your NIC, then the firmware is OK and the kernel recognizes it. Show us the output, please. ip address show If this gets you the correct (or a correct) IP address, then DHCP or static address configuration is good. Again, show us the output. ping 8.8.8.8 If this gets through, then your machine can contact the outside world. At that point, it's probably a DNS issue, and you should report the contents of /etc/resolv.conf to us. -dsr-
