Re: Upgrading the motherboard
There is no way to change the MAC address, but you can make Windows tell the system it has a different address that might fool your other program. Follow the instructions below. Change the MAC address in Windows
Go to Start -> Control Panel. Double click on Network Connections (inside Network and Internet Connections category in Windows XP). The, right click on the active network connection with network adapter that you want to change the MAC address (normally Local Area Network or Wireless Network Connection) and click on Properties.
Above steps work in Windows XP, Windows 2000 and Windows Server 2003. For Windows Vista, access to NIC’s properties is from Control Panel -> Network and Internet -> Network and Sharing Center -> Manage Network Connections.
Alternatively, if you already know which network adapter that’s responsible for your network or Internet connection, go to Device Manager and open the properties dialog by double click on the NIC itself.
In the General tab, click on the Configure button.
Click on Advanced tab.
In the Property section, select and highlight Network Address or Locally Administered Address.
To the right, “Not Present” radio button is by default selected as value. Change the value by clicking on radio button for Value:, and then type in a new MAC address to assign to the NIC.
The MAC address consists of 6 pairs of numbers (0 - 9) and
characters (A - F) combination. For example, 88-17-E8-90-E2-0A. When
entering the new MAC value, omit the dash (-), for example
Click OK when done.
To verify the change of MAC address, go to command prompt, then type in one of the following commands:
ipconfig /all net config rdr
Reboot the computer if successful to make the change effective.

Your MAC address (physical address) is baked into your NIC (network interface card). Your wireless NIC will have it's own mac from your wired NIC. To change it you would need to replace the NIC itself. You can, as an alternative, spoof your MAC address with programs. It basically intercepts all the frames and swaps out your real MAC for your spoofed MAC. If your using Linux, it should already be installed, from a terminal just type macchanger. For windows you would need to download a program. This is a decent one for Windows. http://www.technitium.com/tmac/index.html
The MAC address is the physical address your computer's Ethernet card or network interface card (NIC) uses to identify itself to other computers and devices on your network. There are different ways to find your Ethernet card's MAC address, depending on what operating system and programs you have installed. Since most Windows-based computers have access to the MS-DOS command prompt, using DOS to find your MAC address is one standard way to do it.
There are a couple of different tools you can use in MS-DOS to find your MAC address. All of them requiring opening a command prompt window, which you can do by typing "cmd" into the Run bar on the Start menu (or in Windows Vista or 7, you can type it into the Search bar instead).
Getmac is a utility that is included on Windows Vista computers and on newer Windows XP systems. Typing "getmac" by itself on a command line will return the MAC addresses of any NICs that you have installed in your computer. (If you have an Ethernet NIC and a wireless NIC, for example, Getmac will list the MAC addresses for both of them.)
Ipconfig is a command that will display your IP address if you are currently connected to a network. However, by adding the "/all" switch to it, you can also see your MAC address, as well as many other configuration settings. Type "ipconfig /all" and look for the line labeled "Physical Address." If you have more than one NIC, the MAC address for each NIC will be displayed separately.
Hello, if you go onto properties of your NIC, click 'advanced' , go down to 'locally administered address' ; this is the bit where you can enter your own mac address. See this page or google 'locally administered address'http://www.javvin.com/networkingterms/LAA.html
If you have changed the motherboard then maybe without knowing it you would have changed the MAC address of the NIC. If your router has MAC ADDRESS FILTERING/LOCKING then you will need to connect to your router with a network cable and then add you new MAC address to its filtering table
Please make sure that you have the NIC enabled and on the computer and set to automatic settings for IP address. Now follow the steps below to reset and reconfigure the router:
At the back of the router you will find a small tiny hole (which has a small button inside it). Press the button with the help of a paper clip. and hold it down for 30 seconds. After 30 seconds, please release the button and power off the device for 5 seconds.
1. Connect a Ethernet cable from the modem to the WAN port of the router(isolated port). 2. Connect the computer to the router using any one of the 4 available ports. Please make sure that THERE IS NO DIRECT CONNECTION BETWEEN THE MODEM AND THE COMPUTERS (either using Ethernet cable or USB cable). 3. Power off the modem and the router after making the connections. 4. Power on the modem and wait for the lights, then power on the router.
1. Open the browser(Internet Explorer or Mozilla Firefox). 2. Access the router, usually with http://192.168.1.1 or http://www.routerlogin.com. 3. Login to the router with the Username as "admin" and Password as "password" (please note that the username and password is case sensitive). 4. Click on 'Basic settings' from the left menu and select 'Use Computers MAC Address' from 'router MAC Address' section. 5. Click Apply. 6. Once it updates the settings then power off the modem and the router. Power on the modem and wait for the lights, then power on the router.
I hope this information allows you to resolve this issue.

Tap Settings > General > About then scroll down to Wi-Fi Address, write down the MAC address. Switch your router to MAC address filtering so that a password is not needed, but it will only let the devices whose MAC addresses that you enter connect to your router.
You will have to do the same for your computers as well.
If using a PC. Goto the start menu at the bottom, and select RUN, then type CMD (enter) type: ipconfig /all
You will see the mac address that you NIC or Wireless card has. Enter that in the mac address security as well.
If using a MAC, goto the top left of your screen, click the apple logo, about this mac, more info, goto locations, enter your airport wireless card and or nic Mac.
This is a more secure way to do your security since so many programs can crack wireless wpa and wep these days.
The MAC address is burned in the Ethernet card chip, you won't see it in the Bios or if you do you can't change it. MAC address changer are tweaks to not being tracked.
The solution to know if the card is blown is to do a complete reinstall of your operating system and if then you can't connect whit it, it is indeed dead. Then Disable it in the Bios and had a PCI one to replace it.
Those kind of problem whit network cards happens a lot when you get a power outage, if you had one in the last couple of days your problem is most likely it.
to completely change out the BIOS chip itself from the motherboard and replace it would cost you the same as just buying a new motherboard. it would be cheaper and easier to just take everything out and install a new motherboard.
if what you want to do is flash the BIOS (basically updating the firmware inscribed into the chip), all you need to do is download and install the flash program from the mobo manufacturers website and download the newest BIOS instructions.
let me know which you do. ill help with any other questions.
