How to Find the Ethernet Adapter's MAC Address

If you are using this as ethernet adapter, there definitely are IP addresses for each cable plugged into the router. Your MAC needs an IP address for the router to ROUTE the traffic to and from the internet. That's what Routers DO. Listen to your Support. Unplug all other devices from the router you connect to, then connect your adapter, and let the router assign an IP address to it. Then connect the rest of the devices one at a time, and see if that works. Make sure you plug the cable from the efibre to port #1 on the router, for highest priority of traffic.

The following procedure worked for me :

To change the MAC address of a Dane-Elec MyDitto Classic NAS, use the flash memory configuration hidden page :

http://(ip of your my-ditto)/flash.asp

- Enter the right MAC address (which is written on a sticker, under your my-ditto NAS... something like "001F1Fxxxxxx") in the field "NIC0 address:".
- Click the "Save settings" button. (The same page reloads, with empty fields : ignore it).
- Restart your my-ditto NAS (with the power switch).

After booting, the power led should stop blinking (stay lit), and your NAS should be available through PC client software (master/user usb keys) again.

If the problem remains or reappears (dummy MAC address again), the culprit could be the CR2032 lithium backup battery inside your my-ditto. In my 2-year-old NAS, this battery was too low (2.1V instead of expected 3V). To replace this battery on its socket, you have to open your NAS (voiding the warranty).

Good luck...Hope this helps someone !

Try using the MAC address of the ethernet adapter and clone it to your router. Your ISP might be recognizing the MAC address of the LAN card of the computer.

To get the mac address of the computer go to the command prompt and type ipconfig/all.

You may also need to contact your ISP to clear arp in their end, so that they will detect that you have a router. I hope this helps!

Most likely, your ISP only allows a single MAC address to connect to them. To make this work with multiple computers you'll need a router that can do MAC address cloning, i.e. it reads the MAC address off of the computer that works and presents this to the ISP in all cases even when the request comes from different MAC address.

The MAC address is unique and set at the factory for each ethernet card so it's not something you can or should attempt to change. If you were able to change the MAC address on the second computer to match the first you would break your network rather than fix the problem.

It is also possible that you are using fixed ip addresses and simply need to configure the NIC on the new computer. If you check the IP v4 settings for the old computer and they have an explicit address for the card then this is is the issue. If so, simply configure the new computer to match the old computer but make sure the last of the four numbers in the ip address is something between 1 and 254 that does not match the first computer or the gateway address.

Hi, here is a solution for your problem: Obtaining your MAC address
Your MAC address will normally be on the box or registration card for your computer or individual ethernet card. If you can not find it, please follow the instructions below depending on your operating system.
Windows Vista:

1. Click on Start Button.
2. Click on All Programs.
3. Click on Accessories.
4. Click on System Tools.
5. Click on System Information.
6. Click on plus sign in front of Components.
7. Click on plus sign in front of Network.
8. Click on Adapter.
9. Scroll down to your Network Interface Card and it will list the MAC Addresss. (Make sure you do not get the wireless adapter). 

WINDOWS NT, 2000, or XP:

1. Using your mouse, click on the Start Button.
2. Click on Programs.
3. Click on Accessories, and then Command Prompt.
4. Once a small black window appears, type in ipconfig /all (with a space between the g and the /).
5. Locate the number to the right of Physical Address. This is your MAC address.

WINDOWS 95/98/ME:

1. After clicking on the Start Button, click on Run.
2. In the white space of the window, type in the word winipcfg
3. Click on "OK".
4. Look under the info for the Ethernet adapter. (Your system may also have a modem.)
5. The number next to "Adapter Address" is your MAC address.

Hope this helps.

If you can still access the web based configuration on your linksys router (by going to 192.168.1.1 in your web browser) that means nothing is wrong with the cable/connections. However the ISP is not letting your router get access to the router since it doesn't have the same MAC address as your computer's ethernet card/port.

To change your routers MAC address to the sameone on your computer (So you ISP thinks its still the computer connected), you have to first go to start>run>type in cmd and when command prompt opens, type in "ipconfig -all", which lists your IP addresses, etc. Make sure you add the -all (With a space after ipconfig) or else you can get your computers MAC address. The Physical Address is your MAC address. Now once you obtained the MAC, go to your router configuration, and login. Then look for where you can set or clone the MAC address of the router. The default mac address could be on the bottom of the router, if so check for it and just look for that address in your web configuration, then change it to your computers MAC address.

Hope this will fix it!

This document is relevant if you had an Internet connection, but lost it when: * Adding a router to your network, or * Using a different Ethernet adapter card or computer than the one your ISP used during installation. Use ISP Configuration to see whether you need to "spoof a MAC address" to connect to your ISP. If so, follow the instructions in this document. If the Ethernet card that was used during ISP installation is not available, you may need to register the new Ethernet card's MAC address with your ISP for the following to work. MAC address stands for Media Access Control address (not "Macintosh computer"!), a unique number built into modems, routers and other network hardware. It ensures that one piece of equipment is not mistaken for another one. Some ISPs validate your connection by checking the MAC address of the Ethernet adapter in computer that was registered during ISP installation. If you add a router or change computer or Ethernet adapter, these ISPs will drop your Internet connection, because they find the MAC address of the newly added router or adapter, instead of the one they expect. To fix this, change the router to report the Ethernet adapter's MAC, instead of its own. This is called "spoofing the MAC address". To find a PC's or Macintosh's MAC address, see How to Find an Adapter's MAC address : http://www.fixya.com/ThreadView.aspx?prdid=252225&thid=102075. To Spoof a MAC Address 1. Connect the computer that your ISP's installers used to establish Internet connection to the router. If you are unsure which computer was used, call your ISP, and ask what MAC address was registered. Then, using the instructions in the box below find the computer whose MAC address matches their records. 2. Disconnect other computers from the router. (If you do not want to disconnect other computers, you need to know the adapter's MAC address, as described in the box below. Then, in step 6, type Use This MAC Address, entering the adapter's address.) 3. In an Internet browser type the address 192.168.0.1. 4. Type admin for the username, password for the password, and click OK. 5. Go to the Basic Settings > Router Mac Address. 6. Select Use Computer MAC Address. 7. Click Apply. This automatically gives the router the computer's MAC address. 8. Click Test to make sure you are connected. If you are not connected, contact your ISP.

Connecting the Router and the Modem 1. Connect the Broadband modem to the computer using an Ethernet cable without the router installed and make sure that the Internet connection is active. If it is not, contact your Internet Service Provider. 2. Shut down the computer, and unplug the power cables to both the router and the Broadband modem. 3. Disconnect the Ethernet cable from the computer and plug it into the Internet or WAN port of the router. 4. Take the Ethernet cable that came with the router (or any another available cable) and connect it to the computer. Then, take the other end of that same cable and connect it to Port 2 on the back of the router. 5. Plug in the Broadband modem's power cable and wait for all of its lights to stop blinking. 6. After the lights on the Broadband modem stop blinking, plug in the router's power cable. 7. Start up the computer. Obtaining the PC's MAC Address Windows 98SE/ME 1. Click on the Start menu, then click on the Run option. 2. When the ?Run? window opens, input winipcfg into the ?Open? field, then click on the OK button. 3. The ?IP Configuration? window should appear, select the Ethernet Adapter that the PC is using from the drop down list. 4. Make note of the ?Adapter Address? which is the MAC Address. Windows XP/2000 1. Click on the Start menu, then click on the Run option. 2. When the ?Run? window opens, input cmd into the ?Open? field, then click on the OK button. 3. When the ?MS DOS Prompt? appears, input ipconfig /all then click on the [Enter] key. 4. Make note of the ?Physical Address? of the Ethernet Adapter (normally ?Local Area Connection?). Accessing the Setup Page 1. Open a web browser such as Internet Explorer or Netscape. 2. When the browser window opens, go to the Address bar and type in the router's IP Address and click on the Go button (192.168.1.1 is the default IP address of Linksys Routers). 3. A window will appear prompting for a ?User Name? and a ?Password?. Leave the ?User Name? field blank, and type in the router's password and click on the OK button to login (admin is the default password). 4. The router's web-based ?Setup? utility should then load. Cloning the MAC Address The steps for configuring the MAC Address Cloning feature of a Linksys router vary depending on the firmware version the router is currently using. From the router?s ?Setup? page, locate the Linksys logo in the upper left-hand corner of the page. Follow the instructions below depending on which logo matches your specific screen: If the logo matches the image above ("Linksys - A Division of Cisco Systems, Inc."), follow these steps. If not, skip to the next logo version. 1. From the ?Setup? page, click on the MAC Address Clone sub-tab. 2. In the ?MAC Clone? section, set the option to Enable. 3. Click on the Clone Your PC?s MAC button. Once this is done, the ?User Defined Entry? will show MAC Address of the Ethernet Adapter of the computer you are using. Verify this address with the ?Adapter Address? or ?Physical Address? observed in earlier steps. 4. Click on the Save Settings button. Then, click the Continue button if prompted. If the logo matches the image above ("Linksys"), follow these steps: 1. From the ?Setup? page, click on the Advanced tab. 2. When the ?Filters? page loads, click on the MAC Addr. Clone tab. 3. When the ?MAC Address Clone? page loads, enter the the ?Adapter Address? or ?Physical Address? that was observed in earlier steps. 4. Click on the Apply button. Then, click the Continue button if prompted. Power Cycling 1. Shut down the computer. 2. Unplug the router?s power cable. 3. Unplug the Broadband modem?s power cable. 4. Wait for 30 seconds. 5. Plug in the Broadband modem?s power cable and wait for its lights to stop blinking. 6. Plug in the router's power cable once the modem?s lights stop blinking. 7. Finally, start up the computer and test the Internet connection.
