Suggest doing the following. (and I appologise if I may seem patronising I don't know how much IT experience you have
so no offence)
Firstly Turn off the computer & Modem.
Now:
1. Plug ethernet (LAN) cable into modem.
2. Boot modem and wait until lights are steady green.
3. Boot Laptop & Log in (if applicable).
Now check whether you have an IP Address.
If not follow suggestions below:
1. Click on Start and choose Run
2. Type
and press enter
3. In the box type
4. Look for your Ethernet Adapter and check its ip address. If it's still a private IP (eg 169.xx.xx.xx) then keep reading...
5. at the command prompt type
Code:
IPCONFIG /RELEASE *
6. Type
Now try
once again and see if an ip address is there that isn't a private one.
There could well be a problem with your modem if this does not work. I am presuming that you aren't using a router too.
