I am having an extreme problem with my network adapter. I recently discovered that my onboard ethernet adapter was somehow incompatible with Windows 7 Ultimate x64.
Yesterday, I got a brand new wired network card. After installing it in the PCI-E 1x slot I started my computer up.
I checked my network, and as I was expecting to see a "Connected to Network" message. I got a message in my connections that I was connected, but it was to "Unidentified Network" with "No Internet Access." I rebooted, just to get a "No connections Available" message in my connections box.
In the Network and Sharing Center I had a message saying to plug in an ethernet cable. Obviously, I had already done this. I tried with another cable, even directly connecting it to the cable modem itself (I originally had it connected to port 1 on a Cisco Valet.)
I even tried resetting the "TCP/IP" stack, also to no avail. After letting the computer down for a while, I booted back into Windows 7, and what do you know, "Unidentified Network, No Internet Access." After tinkering around some more, like setting the IP up, it went back to "Network cable unplugged."
I am now not knowing what to do. I also tried other things like:
Restarting
Switching Cables
Disabling and Re-Enabling
Updating Drivers (all were up to date!)
All to no avail. Thank you for all of your answers, and I would be glad to provide more information, Scott
P.S. I am only 12, so please do not get mad if there is an obvious answer!
UPDATE:
I've removed all image links, but here's the Cmd for netstat -rn on the Laptop which works:

And for arp -a it comes back with an err saying no ARP entries found.
Thanks for all the help!
ping xxx.xxx.xxx.xxx
xx.. being your routers IP. Do not reuse the same IP on different network-devices, but use the same subnet (like 192.168.0.x) and subnetmask like (255.255.255.0).
