Why the ISP or cable modem company need to know my modem cable MAC address if I bought a new one, beside that received from a modem cable or ISP company?

The cable provides tend to lock their network by MAC address or they assign you an IP address based on your cable modem MAC address.

Some (for example cable Telewest in the United Kingdom), used to go as far as locking down for the mac address of the PC connected to the cable modem, which is why some routers have the ability to clone the mac address of a connected device.

  • Why is the MAC address Clone?

    When I disabled it Clone MAC address I lost access to the internet.

    Does anyone know why MAC address Clone is necessary and what it does?

    Clone MAC address changes the MAC address of the router on the internet port.

    You can use the function of the cloning MAC address to clone the MAC address of a computer if you used before your computer directly to the modem.

    Some ISPS (especially cable ISPS) only the customers to have an active internet connection at any time. To do this, check the MAC address, that is, they remember the MAC address that accessible line via the modem and lock the connection to this MAC address.

    If you test your internet connection directly with your PC first and then connect the router the router can not get an internet connection because the row is locked to the PC's MAC address. Now if clone you the address MAC from the PC on the router the router "pretended" to be PC and the ISP will accept traffic again.

    Usually, simply reset or turn on the modem to reset the lock again. Sometimes, you have to turn off the modem for a couple of hours (for example, through the night) after a few hours of inactivity the ISP removes the lock again. Sometimes call the ISP to remove the lock, but it's not very often.

    So basically, generally useless clone MAC address at all because you could accomplish the same thing by resetting the modem or it turned off for a few minutes. If you connect the router to the modem, ISP learns the MAC address of the router and it gets working internet connection. (Of course remember, that once a computer directly connected to the modem would not get active internet connection unless you change the MAC address of the computer to the MAC address of the router).

    But the function is useful if you do not want to. You simply set the MAC address of the connected device before, and you get a working internet connection.

  • where can I find the mac address for Airport Extreme

    just bought a new Airport Extreme 802.11ac and I don't know here to find the MAC ADDRESS. Can someone tell me where to look. I have the model and serial number, but can not find the MAC ADDRESS.

    Is the AirPort Extreme, set up and operation right now... even if he could not have an Internet connection?

    If Yes... Open the AirPort on your Mac utility... (Finder > Applications > utilities > AirPort Utility)

    Hold down the option key on your Mac when you double-click on the image of the AirPort Extreme

    The next page will display a summary of the parameters

    The AirPort Extreme has done 3 different MAC addresses... Ethernet, WiFi 2.4 GHz and 5 GHz WiFi.   If your AirPort Extreme is connected to a modem by an Ethernet cable, then the Ethernet ID is the MAC address.

    If the AirPort Extreme has not set up yet at all...

    Open AirPort Utility as above, and then click the file menu in the upper left corner of the screen next to the Apple icon

    Click on configure the other

    For address, enter 10.0.1.1

    A password is normally not necessary, but if you are prompted for a password, use the word

    public

    Click OK, the settings summary page is displayed.  In most cases, given that the AirPort Extreme connects to a modem via an Ethernet connection, you want to use the Ethernet ID as the MAC address.

    If you are still experiencing difficulties, you have 90 days of support Apple phone. Call them and maybe they can explain why that should be a very simple task is so difficult.

  • Advantage of the MAC address cloning?

    What is the advantage of the MAC address cloning?

    There is no "advantage" to clone the MAC address. The only benefit would be to have internet or not.

    In many cases, it is absolutely useless to use the clone MAC address. If you have an internet connection through your router, then there is no need to use the MAC address cloning feature.

    Only when you find that you have a working internet connection on a computer directly on your modem, but not when you connect through the router (or another computer directly into the modem) then it is necessary to use the MAC address cloning feature.

    Usually, this is only the case with cable TV ISP. They allow you to have an active internet connection single at any time. They do this by remembering the MAC address which connects via a specific modem. If you connect first a computer for testing directly to your modem, you will have an internet connection. Now if you connect a different device to your modem it does not work is because the ISP has always blocked the internet connection, the MAC address of the first computer.

    How to remove the lock depends on the ISP and the modem. Sometimes just reset the modem or to turn everything off. Sometimes you turn off everything for a few hours and after that the first connection device is the one with the internet connection (i.e. make sure you connect the router then...) If you want to know exactly how your ISP to do this, you need to ask...

    The simple solution is to use the MAC address cloning feature. The router "clones" the MAC address of the first computer, i.e. it basically pretends to this computer. The MAC address is accepted by the ISP and is immediately authorized to the network. You have a working internet connection on the first computer, either through the router directly because both use the same MAC address. (This is no problem on the router because the MAC address is used on the internet port only...).

    Of course, remember all this. If at some point later, you connect another computer directly to the modem (for example you have connection problems and want to know what is wrong) you can "lock" in a different MAC address for your connection and you will have to wait to find the connection to a different device.

    But once again: there is absolutely no need to use the clone if you have an internet connection through your router.

  • How to find the MAC address for photosmart c510 - printer, not zineb

    HP Photosmart c510 all-in-One

    Windows 7 SP1

    Printer bought 2 weeks ago.

    Printer wireless light is not on, not even flashing

    I use MAC address filtering on my home wireless router.  No problem adding the Zeen, I found that it is easy MAC.  Of course for the printer, it says "Printer not available" on the display of zineb, just below the zitoun MAC address.

    So I need to add the MAC address of the printer to my router.  I know that I can turn off filtering by MAC address and I hope that the printer connects, and then I can print the printer network settings, get the MAC, and then again turn on the filter and add the printer Mac

    Is this the ONLY way I can get the MAC address of the printer?  I'd rather not have to do that whole process, but will if I have to.

    I also wonder why the printer wireless light is not even blinking as he is looking for a network.

    Can anyone help?

    Print a network Test Wireless in the network menu on the front of the printer. It will contain the MAC address. Note that MAC filtering is not in that ensure that used MAC addresses are sent in the clear, and it is easy to impersonate a MAC address on a computer.

  • Manually change the MAC address

    Hello

    a client needs to keep the same MAC address for a virtual computer in its vCenter to import into his org in vCD.

    Because this server has an application and that its license is tied to the MAC address, they must keep the original MAC address. I know that I can make this request on vCenter, but not through vCD.

    Is there some sort of workaround?

    Removal and addition of the vswif of the service console should generate a new MAC address.

    esxcfg-vswif - l

    Note the detail.

    esxcfg-vswif vswifN d

    where N represents the number of vswif, d Deletes

    esxcfg-vswif - a n-i < IP > < vswifN > < portgroup > Pei, netmask

    is the command to add a new vswif, even when N is the number of vswif.

  • Determining the MAC address generated by VMX

    How the MAC addresses are generated when a new virtual machine is created/cloned using ESX and especially LabManager?

    Is the set of predictable, algorithmic MACs potential, or is it completely random?

    The use case, is that I need to know all of the potentially valid MACs which can be assigned to any given virtual computer.   It is calculated from the CMA of the physical host?  Is it still a finite set?

    Any idea is appreciated.  Thank you

    Generated by the Lab Manager MAC address will be in the following format:

    00:50:56:XX:NN:NN

    Where XX is the installation ID of your Lab Manager you will find on the General Settings page. Remember that you must convert to the spell. Example, if your installation ID is 41, so all your MAC address will look like 00:50:56:29:NN:NN.

    NN:nn is the unique number assigned to the network adapter. each virtual computer

    So let's say that I log in the laboratory Manager (whose installation ID is 41) and create a virtual machine with two network cards. It can assign these MAC addresses to my two network adapters:

    00:50:56:29:00:60

    00:50:56:29:00:61

    Now say I have add a new network adapter. The MAC address assigned to the third NIC will be 00:50:56:29:00:62.

    Now let's say I delete the first NETWORK card MAC address is 00:50:56:29:00:60. Then I go and add a new network adapter. MAC address will be 00:50:56:29:00:63. The MAC address that was previously removed won't get recycled, at least not immediately.

    In order to predict the MAC address is doable as long as you are aware of all MAC addresses in use on your system.

  • Feature request: Advanced mode to display the MAC address of the network card

    When a virtual machine has multiple network cards, and when it is not easy to get/know MAC address within o/s comments, it would be nice if there is a way of GUI for the MAC address for any individual network adapter.  I don't mind if this function is in some "advanced only user" box, as long as it is available.

    I know that it is also possible to open the .vmx file for this information, but if there is a sort of GUI, why not?

  • Old PITA bread - change the MAC address in VMware Workstation 6.5?

    Some versions of VMware Workstation enabled to manually set the MAC address of the virtual card.

    This possibility has been changed for several reasons.

    My personal opinion is clear.  A virtual machine needs to reflect as much as possible a hardware machine.

    VMware Workstation you can not change the MAC address, or you are related to a limited possibility, were the first hex addresses are fixed,

    so that it shows on the outside, it is a virtual machine.  VMware response is, you must run the server edition.  Well...

    Currently, I have seen, that the recent version of Virtual Box allows you to manually enter the MAC address

    for the virtual Interfaces based on Intel NIC. You can enter any MAC address, including existing material, NIC Intel MAC.

    So my opinion, the possibility of lock-out to COMPLETELY change the mac address of the virtual machine,

    must be activated again for all versions of VMware, as it is the option with other software.

    I wonder why should I do a subset of the first string to extract only the part of the MAC address. The regular Expression function is not able to recognize the regular expression directly in the middle of a string?

    I only works when I extracted the subset of tring right as in the picture below.

    Thanks for your replies.
