My sister's computer lost internet connectivity out of the blue a few days ago. It's nothing with the router or modem, because my computer is fine. I've tried everything i know how to do to fix her computer, but i can't seem to figure out the problem. The only thing i've noticed that definitely seems wrong is that when i go to control panel, and network connections to view the details of that connection, the physical address is all 0s.
I'm not really sure what could be wrong. It has to be something with her computer. Could her ethernet card be shot? I doubt that she would know how to change any network settings, so that's the only thing i can think of. I'd really appreciate any info.
try these 2 things:
goto control panel, system, hardware, device manager...check + next to network connections, right click on her network card and uninstall...re-boot system and let it be re-configured...see if the address is still all 0's...
if it is try this next...download this:

and run it on her system, re-boot and check internet connection...
Good Luck

Is your network setup such that you get your IP information from DHCP?
If yes, before you do anything else, check your sister's NIC and see if it's set to DHCP. If it isn't, make it so and then reboot.

I checked to see if its set to DHCP. I might be overlooking it, but i don't see any setting i can change. It does seem to be set correctly though, it says "assigned by DHCP.

What does ipconfig show?

You need to open a Command window first. Then run ipconfig /all

"lol well i'm not sure. every time i run ipconfig, the window closes before i can even try to look at anything."
Are you running ipconfig /all from a command prompt, or just typing ipconfig /all directly in the Open window in Run? You need to type cmd in the Open window in Run to show your command prompt window (looks like an old-fashioned DOS window). It's at the command prompt in the "DOS" window that you need to type ipconfig /all, and then hit the Enter key.

ahhh ok. well after looking at ipconfig, i see that dhcp is enabled, and all the other information looks correct. The only thing that seems wrong is that the physical adress is still all 0s.
im no expert, and i could be wrong, but it sounds to me like her computer maybe isn't detecting the ethernet card. that sound right?

So. To ask yet again, what does ipconfig show? What is showing as the IP, Subnet, Gateway, DNS Servers, etc?

When I asked the following above: Is your network setup such that you get your IP information from DHCP?
I meant, do you have a DHCP server providing TCP/IP settings to clients?
If you don't, and the client is set to "obtain IP address automatically" (that's DHCP) then it definately won't work.
If you do have a DHCP server somewhere in your network, and your client is set to "obtain IP address automatically" and your ipconfig /all shows all 0's in the IP address, then you have a problem which could be the NIC.
Now, if you can answer Jennifer's question (immediately above mine) and mine, we can hopefully help you figure out what's wrong.

If the physical address aka mac address is all zeros it can't be addressed. This is below the protocol level.
Very well may be a dying/dead nic
'tis the season to be of good cheer. Wishing one and all happy times with family and friends.

Ok, sorry about the confusion.Ipconfig results:
Physical Address = 00-00-00-00-00-00
Autoconfiguration Enabled = Yes
IP Address = 192.168.1.4
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.1
DHCP Server = 192.168.1.1
DNS = 192.168.1.1"do you have a DHCP server providing TCP/IP settings to clients?"
I don't really understand. Looking at the connection status for my computer (which isn't having a problem), it says it's assigned by a DHCP.
The modem that we have is a modem/router combo. Would that provide TCP/IP settings to our computers?
Sorry if i'm not giving enough info, i'm no pro at this.

You're getting an IP address but the MAC address if the NIC isn't correct. Open the device manager and network adapters. Are there any yellow or red marks next to it? Does it say that the device is working properly? You might want to install a different NIC if you can't update or reinstall the drivers.

I've looked in Device Manager and there aren't any red or yellow checks. Everything appears to be running normally...except it isn't lol. Someone suggested uninstalling the NIC, and then rebooting to let the computer sort of reset it. Didn;t seem to do anything tho
0
I generally don't do it that way. I delete the NIC in the device manager. It's different than uninstalling it. Then reboot and let windows find it as new hardware. However, at this point, I would try another NIC.

nics have "locally administered" physical address.
Go into the properties of the nic
go to the configure button
go to the advanced tab
choose "locally administered address"
put in a hex value for the address
example:00-90-27-05-95-0b'tis the season to be of good cheer. Wishing one and all happy times with family and friends.
