Physical address (AKA "MAC address") is in practice only significant if it is one computer attached to some broadband connection device. This is because ISPs sometimes want to protect themselves from private home users attaching a whole bunch of computers (that would use lots of resources) to internet, while only paying for a single-computer connection.
So, upon installation, they use the computer's network card MAC address as a sort of "password" that lets the connection be established. If you later substitute this computer for another one, or for a router (that would allow more networked computers to use this internet connection), the security mechanisms will not allow it to connect.
To remedy that, most routers have an option to change their outside MAC address to mimic the one that the ISP's security system expects.
1) You have to find out your working computer's MAC address. It is 6 pairs of hexadecimal digits, separated by colon, space or a dash (in Microsoft systems it's a dash). Simplest method would be to go to command prompt, type "ipconfig /all" and look first for the network card that is actually used to connect to the internet (there might be several of them, be sure to choose the proper one), and second for this adapter's physical address. Write it down.
Sometimes the MAC address is written on a label attached to the network adapter.
2) Go to your router's configuration, find an option to change MAC address, and input the written down values (pairs of characters, separated usually by a colon, contrary to a dash used by Microsoft).
Testart the router and see if it works.
If a router is in reality a Linux box for example, search available documentation on ways to change the MAC address.

How do computers connect to the Internet?
Internet Protocol SuiteeConnecting to the Internet consists of having a physical connection to a network which has a connection to the Internet, having an address that works on the Internet, and having routes to destinations on the Internet.Modern computers have a local area network (LAN) port which uses the Ethernet protocol (IEEE 802.3). Through this port, a cable consisting of at least four wires connects pins 1&2 and 3&6 as receive and transmit paths to a connection device. That connection device, be it a switch, hub, or router, allows the physical connection to be successful.Once the physical connection is there, the computer either uses a built in hard-coded "static" Internet Protocol (IP) address, or it requests one "dynamically" via the Dynamic Host Configuration Protocol (DHCP).Finally routing is either statically assigned ("set default route") or it is provided by the DHCP server as the "gateway" address.A computer which has the physical connection... which has a valid IP address... and which has a route to other destinations is therefore connected to the Internet.
Internet and messenger is not working but i still have Internet connection?
Your computer is saying that you still have the connection when you don't actually (sometimes they do that), or your ISP has revoked your Internet access (but not the connection itself) for some reason.
