Hi.
My inbuilt network card got broke by lightening. I took the machine to the
pc store to check that the rest of the motherboard was ok and if so to put a
new network card. Picked it up, they said a new network card was fitted and
all was well. Got it home and nothing. Doesn't connect to the internet or
the network.
The network card is there and enabled.
It detects if the cable has been plugged or unplugged.
It detects if I unplug the cable from the Router/Modem.
The IP address is totally random and not in the range of our network.
If I put in the IP address, it still doesn't work and is still not being
seen by the router.
The cable from the router to the pc is working coz I've checked it on
another pc.

I can't imagine why it doesn't work at home when they said it worked in the
shop. Or don't they go online to be sure?
Please help!

Some ISP's tie the service to a particular MAC address. Call them.

A couple of ideas:

When the NIC gets an IP address, does it begin with 169? If so, that's Microsoft
Windows's self-applied IP address when it can't get one from the router.

Have you disabled the on-board NIC?

Have you installed the latest drivers for the new NIC?

If this still doesn't fix it, I suggest bringing it back to the shop that
installed the new NIC. Of course, you might do this first, as they installed it
they should have made sure it was working.
 
Also, is your router firewall configured to block all MAC addresses, except for
the one on the on-board NIC? If so, then you got a problem. If you can find out
the MAC address of the on-board NIC, you can change the MAC address on the new
NIC in Windows to match the MAC address on the on-board NIC.
 
You'rer right. The IP address is beginning with 169. When I put the one that
applies to my network, theres no difference. I've checked the router's
firewall and that's no blocking anything.
The shop said to bring it back tomorrow morning but insisted that they
tested it was working ok.
Isn't it weird that it says it's connected and all that but isn't. Is it
something to do with a part of the NIC as according to the Network status it
says Packet activity is 0

Forgot to say that in the router setup, I use Address Reservation and there
it still had my PC with the old NIC. So I changed it to the new one.
By that only reserves IP addresses surely and not blocks others?

Couple of things:

On the new NIC, I presume you had it set up to automatically obtain an IP
address and DNS addresses? I hope so.

Then, when that didn't work, although you put in a correct IP address for your
network, did you also put in the correct subnet, gateway, and DNS addresses?

When you say that the router uses Address Reservation, I can only assume that
you are correct that it means IP address reservation, rather than 'reserving'
access to the router to a particular MAC 'address'. The NIC's manual or help
menu might clarify this. If it means IP address reservation, that is probably
OK, especially if you gave the new NIC a different IP address, but one that is
in the same range.

Let us know what the computer store finds.
 
I should also have asked you: your router IS set up to issue IP addresses, etc.,
right? (That is, it's set up to do DHCP.)
 
Most cable system do need the MAC. In addition, be sure the
on-board NIC is disabled and only the new NIC is being
detected and powered.

Yes it is.

Yes I did

The onboard NIC is not being detected at all after the ligntening strike so
there's nothing to remove.
I made absolutely sure that in the Router setup the Address Reservation was
not the cause.

It is now back at the store.
I will let you know as soon as I do.
Thanks for your help.
 
The shop confirmed that the motherboard had become unstable after the
lightening.
I did sense that things weren't quite right although apart from the NIC I
couldn't quite put my finger on it.
Hopefully that'll be that
Thanks again

Nevertheless, look in the BIOS setup, whether it can be disabled there, and do so.

Open a command prompt. Do ipconfig /all. Post the result.
