Network Card no connectivity is it the hardware or software?
Card no connectivity, with LED's on...
Lets say you can not connect,
you do not have an ip listed when you run ipconfig. You can do a little trouble shooting before you call the "Geek Squad".
ipconfig will return a list such as:
Connection-specific DNS Suffix : DSLYOURHOUSE.COM (This is router
specific, yours may not have this)
IP Address. . . . . . . . . . . . : 192.168.1.10
Subnet Mask . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . : 192.168.1.1
Check the Network Card Interface (NIC) LEDs, solid green LED means the
cable is connected and working. Amber LED flashing means there is
activity between the NIC and the other device the cable is connected to.
Setting the IP
If your system is set for DHCP and you are getting your IP from your Cable Modem
or DSL Router you can fake it out by entering your own ip. Most generic Cable
Modems and DSL Routers use this subnet to give you an IP: 192.168.1.X where X is
any digit above 2.
If you have more than two computers connected to your Cable
Modem or DSL Router use this IP to fake out the DHCP: 192.168.1.130, you will
also have to set the subnet mask: 255.255.255.0 and set the gate way:192.168.1.1
Don't worry about the lower block for DNS.

Now go to the command prompt you opened and type: ping 192.168.1.1
You will either get a reply from the Cable Modem or DSL Router or you will get a
time out on the reply.
If you get a reply from the ping then shut your system down and restart, once it
is running again go back to the NIC properties and remove the ip address you
put in, just check the DHCP radio button, apply changes, this should take a
short period to complete.
Go to the command prompt, type in ipconfig,
does it look like the sample?
If it comes back with an IP, in the command prompt type: ping 192.168.1.1
Do you get a reply?
From the command prompt type: ping www.google.com
Reply? Yes? Fixed.
Note: If you are behind a proxy (see
Glossary) then you would ping another IP address on your LAN, the proxy does
not allow for a direct connect to the internet.
Note: 99% of errors are caused by the setting for Duplex and Speed for
the NIC, check the properties of the NIC under the Advanced tab and set it for
FULL/100 MBPS or FULL/1000 MBPS (1 GB) because the default maybe
HALF/10 MBPS (even 40+ years later...)
