MAC Address Cloning?

I am currently connected to my dorm room network with my AirPort Extreme successfully. However, when connecting for the first time, you are prompted to enter a username and password on a web page which authenticates your machine for the first time. The problem is, if I want to hook something else up wirelessly (Apple TV or PS3) I have to re-authenticate it using the web login, thus disconnecting my Mac from getting online.
I am thinking that I can probably authenticate my Mac, then clone my MAC address to the router, but am not really sure if that will work or how to go about it. Can someone please provide some insight on going about doing this? Thanks.

Does changing it to bridge mode give the same responce?
Using share ip would mean that only one of the uni's IP addresses would be associated with the airport base station. In bridge mode any device attaching would get a different uni IP address. This may allow multiple devices to attach, but without knowing the full set up, I can't really help any further.

Back to 'mac address cloning'

My last 'mac address cloning' issue was solved, but now I have another. Before I had to reset my router to disable and reset everything and it worked. Now I have to enable 'mac address clone' to get my pc and server to let me connect to them (thru 'MSTSC') with my wireless laptop and then I have to disable it to get on the internet. Is there a way for the pc and server to be reset and start off fresh?

This is very likely to be a name resolution issue. When you do not have the MAC address cloned and you ping dan-pc, do you get replies?
Unless you have either a WINS server set up on your network, or all of your PCs have static DHCP leases at the router, or you run your own internal DNS server, or you have LMHosts file entries for all of your internal machines, it is unlikely you wil be able to resolve the names of the PCs on your LAN.
The easiest way for you is probably to reference them by IP address. If you changed the port they are listening on so you can access them seperately from outside your network (when you are not home for instance) you should append that oport number to the IP address in the mstsc address entry block, ie 192.168.1.10:3389 for one and 192.168.1.11:3399 for the other (that is as an example...I don't really know the IPs or the ports you used....

Mac address cloning / BT Home Hub 5

I have Infinity 2 package with BT Home Hub 5.
I recently bought Asus AC3200 and would like to use it as a main wired/wireless router in the house.
I don't want to have an extra routing hope, so I thought to setup Mac address cloning, so AC3200's broadband interface has the same MAC as BT Home Hub.
Is it possible ?
Where can I find MAC address of BT Home Hub 5 broadband interface ?

Are you trying to connect a 2nd router to the phone line at the same time? If so it won't work. If not why are u trying to clone the mac address? You can only have the same Mac address once within the same network. Arp cannot understand multiple devices with the same Mac address. You can only have a mac address known to one device. Multiple IP addresses can map to the same Mac address but you cannot map the same IP address to multiple Mac addresses.

AEBS and Comcast (can I clone a MAC address?)

I am currently an Earthlink DSL subscriber. I love Earthink, but DSL is giving me all kinds of trouble. Covad owns the lines in my area and they are aweful... in any case...
I am going to switch to Comcast Cable Broadband. I have set up many people in the area with Comcast and a wireless router. It seems that Comcast does not do this everywhere, but in my area they "bind" to the MAC address of the NIC that you use to setup the connection (MAC Address Authentication).
If I want to use NAT on my router, it will not work unless I can spoof the MAC address. This is easily done with a Netgear or Linksys router. This does not seem to be a setting in the Airport Admin Utility.
Is there a hidden setting or a third party utility that I can use for spoofing the WAN MAC address on my Airport Extreme Base Station?
I could switch to a different wireless router or put a small router between my Cable modem and the AEBS, but I would rather not add a layer of hardware or switch hardware if I don't have to (I really like my AEBS).
Thanks for any advice.
WT

It should be possible, if manual registration of the MAC address of connected equipment is required on Comcast's service in your area, to get them to either clear the binding to allow a new device (ie the Base Station) to associate with the connection, or to ask them to manually register the MAC address of the Base Station's WAN port. I realize you would rather not have to deal with Comcast's tech support people, but (as pointed out above) the only other option is to use a different wireless router that does support MAC address cloning.

Attempting to clone MAC address, cannot save changes.

Hello.
I am attempting to use the MAC address cloning feature on my Linksys e2000 router. When I check "Enabled" and then attempt to save settings I receive "The values you entered are invalid. Please try again." I also receive this message if I select "Enabled" and then "Clone My PC's MAC". All other change to settings seem to work.
Any help?

You might have to reset to factory defaults since there isn't any reason why this is occurring AFAIK. Maybe trying to clone the router's MAC onto itself broke something in the firmware.
Please remember to Kudo those that help you.

Advantage of cloning the MAC Address?

What's the advantage of cloning the MAC Address?
Solved!
Go to Solution.

There is no "advantage" of cloning the MAC address. The only advantage would be to have internet or not.
In many cases, it is absolutely unnecessary to use the MAC address clone.If you have a working internet connection through your router then there is no need to use the MAC address clone function.
Only when you find that you have a working internet connection on one computer directly on your modem but not when you connect through the router (or a different computer directly on the modem) then it is necessary to use the MAC address clone function.
This usually is only the case with cable TV ISPs. They only allow you to have a single active internet connection at any time. They do this by remembering the MAC address which connects through a specific modem. If you first connect a computer for tests directly to your modem you'll have an internet connection. Now if you connect a different device to your modem it doesn't it's because the ISP has still locked the internet connection for the MAC address of the first computer.
How to remove the lock depends on the ISP and the modem. Sometimes it's enough to reset the modem or to power down everything. Sometimes you have to power down everything for a few hours and after that the first connecting device is the one with the internet connection (i.e. make sure to connect the router then...) If you want to know exactly how your ISP does this you should ask them...
The simple workaround is to use the MAC address clone function. The router "clones" the MAC address of the first computer, i.e. it basically pretends to be that computer. The MAC address is accepted by the ISP and is immediately allowed to the network. You have a working internet connection either directly on the first computer or through the router because both use the same MAC address. (It's no problem on the router because the MAC address is used on the internet port only...).
Of course, you have to remember all this. If at some later time you connect a different computer directly to the modem (e.g. you have connection problems and you want to find out what's wrong) you may "lock" in a different MAC address for your connection and you'll have to wait again to regain the connection for a different device.
But again: there is absolutely no need to use the clone function if you have a working internet connection through your router.

Block cloned MAC address in WCS

Hi I would like to ask if I can block a user who connects to our network and generates high usage of internet.
The problem is every time he clones his MAC address.
PS ...( WITH OUT SETTING A PASSWORD ON THE APs AND WITH OUT SWITCHING THEM OFF)
THX

Chris
Only way to prevent it is to do exactly what you mentioned you don't want to do and that's set a password or eap security. Layer 2 hacks have been around for ages. Very hard to defend unless you lift security requirements.

No option of cloning MAC address

I was about to order the 2TB Time Capsule when I did an internet research and found out that there is no way to clone the MAC address of my existing Netgear router to the Time Capsule.
Last time I requested a change from my ISP it took several phone calls and left me without internet access for a week. I'm not willing to go through this again.
That's bad - for me since I really wanted the Time Capsule; - and for Apple because I won't buy it.

It's really too bad the Airport and Time Capsule do not support changing the MAC address. Editing the MAC address is a technology (an officially sanctioned technology BTW) that's been around as long as Ethernet (and was present on Token Ring as well)
http://en.wikipedia.org/wiki/LocallyAdministeredAddress
Right now I have a bug where one of my computers keeps dropping its WiFi association, but there is a workaround to set the first byte of the MAC address to a nonzero value. (I've confirmed all my apple gear has zeroes as the first byte). I can change this on my Belkin N1, and on every other machine, Apple or not, that I own. But, I can't change the address on my Airports. Changing the MAC address is a legitimate part of the 802 specification and I wish it were supported on the Airports. I have a significant investment in them, this minor technical detail would be an unfortunate reason to not be able to use them as access points.

How do I clone my computer's MAC address on to the AE base station?

This is just driving me nuts. I've looked at responses to this question on the internet, and it appears that the Airport Extreme Base Station can't perform a function that nearly all WAN home routers have been able to perform for a decade: "cloning" a MAC Address. My internet provider uses the MAC address of one of my computers to identify a valid connection, and my old Belkin router just cloned the computer's MAC address. If the AEBS can't do that then it's a rather serious design flaw, and if I'd known that I'd never have bought the device. I noticed that there's something called a "Client ID" so I input my computer's MAC Address for that, but the Base Station still can't connect to the internet.
I don't want to have my ISP reset my valid MAC address (even if they could, which isn't clear to me) because I may need to connect to the internet directly in the event of problems... say the Base Station malfunctions.
I bought the base station so that I could connect peripherals to it, but if it can't connect to the internet that renders it practically useless.
Are there any workarounds? Anyone have any ideas?

I can see that no one is bothering to respond to this question, so I thought I'd post a resolution. I don't know if one can alter the ID of the AE Base by cloning a computer's MAC address. The next best thing would be to easily alter the MAC address that the ISP identifies as legitimate. If you have COMCAST's telephone modem (which has a battery backup so that it can't be rebooted by simply unplugging it) you can adopt the following procedure to reset the MAC address.
1. Reset the base station, by depressing the reset button in back with a pen or paper clip.
2. Unplug the base station.
3. Reset the Comcast cable modem, by depressing the reset button in the back with a pen or paper clip.
4. Plug the base station back in.
5. Use the Airport Utility to set the parameters of Airport Extreme.
This procedure will force COMCAST to recognize the Base Station MAC Address as legitimate for provisioning.
It's not an ideal solution, but it works. If the Base Station fails and you have to use a direct connection to your computer you can follow a similar procedure to reset the modem, and recognize a new MAC address.
Again, the fact that you can't use the Base-connected drives for Time Machine is just plain dumb. Apple originally touted this as one of their main selling points, and then just backtracked. They need to reintroduce this functionality in the next update of Leopard... and it wouldn't hurt to issue an apology for having misled people. The stone wall just ****** people off, as it should.

WRT54GL MAC ADDRESS FILTER

Hi I have a wireless access point WRT54GL and i configure it with mac address filter but it allow me to put only 40 mac and i need more? Is there any way to add more? Thanx

Install 3rd party firmware like dd-wrt or hyperwrt+thibor. That should give you more. However, remember a bad flash may brick the router and is not covered by warranty.
Also remember, that the wireless mac address filter does not provide you with any reasonable security. MAC addresses are quickly captured and quickly cloned. It only takes a few minutes to gather some mac addresses which are allowed into your wireless network and that's it.
Set up wireless security with WPA2 or WPA and a strong passphrase. That's all you can do to really protect your wireless.
If you want more detailed access control, consider installing a RADIUS server and using user/password authentication based on WPA2 or WPA (using the RADIUS or Enterprise variants).
But the wireless mac address filter is widely overrated as security mean and only requires a lot of work and time to maintain the lists.

Need to disable "Block Anonymous Internet Requests" with "Clone MAC address?"

Ok -- so I learned from tech support and this forum that the "Clone MAC address" option needs to be enabled when connecting to the Internet via a cable modem. In one of the forum posts (sorry lost track of which one), it said that in addition I need to disable "Block Anonymous Internet Requests" as well -- is this correct? If so what is the effect of this? Linksys documentation is not clear if this is absolutely necessary.
I think the comment is in this thread
http://forums.linksys.com/linksys/board/message?board.id=Wireless_Routers&message.id=8600

Usually resetting you cable modem will allow you to use a router without cloning the MAC address. Reset modem, power down, plug router into the modem, power up the modem, power up the router and you should be good to go. The popular reason that I know of for unchecking "Block Anonymous Internet Requests" is when you plan to use P2P software like Azureus. Your computer becomes pingable and can be seen on the net.

3 computers 1 MAC address

ok, only 1 MAC is allowed on my home network however i had changed my MAC address on my ipod and macbook to be the requested address and everything was working perfectly (two computers with the same MAC browsing at the same time) then the airport was reset and now when any of the computers attempts to connect to the internet for the others it drops out. any ideas?
i have access to all computers but not the airport (unless someone tells me the terminal command i read of somewhere) thanks in advance

Why don't you disable the ACL (access control list) rather than messing around with cloning MAC addresses? As you have noticed, cloning MAC address is rather easy, so ACL won't deter someone who's trying to gain access to your wireless network.

WRT600N weird MAC Address issue

I've had the Linksys WRT600N for several months. One day the internet connection stopped working, after I power cycled it, I called support and they had me change the router to clone MAC address after that it worked. If I took off the cloned MAC the internet wouldnt work. So I got curious after that and I restored the router the settings file I had backed up previously. I tried my internet connection and everything worked. No clone MAC address, however, after about a month it stopped again. The issue was making sure clone mac address was on. My question is why does that keep happening there shouldnt be a reason that it would need my computers mac if my isp doesnt need me to do thaa. (ISP = Optimium) Has anyone had this problem or know what the cause is?

You have to tell what you did exactly if it did not work.
Generally: many ISPs (most cable ISPs) only grant you a single public IP address, i.e. a single device connected to their service. Most do this by storing the MAC address of the device connected to the modem. If you connect a different device with a different MAC address into the modem they won't accept it. You won't get an IP address. You don't have internet. Only the device with the MAC address stored (or a modified MAC address set to the stored MAC address) will have internet.
Some ISPs reset the stored MAC address if you call them. With a few ISPs this is the only option.
Most ISPs reset the MAC address after a few hours of inactivity or in fixed intervals.
Some ISPs recognize if you reset the modem and reset the MAC address then.
After it is reset you can connect a different device and it will get the IP address.
Now, if your internet at some point does not work and for a test you connect the computer directly to the modem and you get internet then, at that moment you already have locked in MAC address of the computer and you have to use the MAC address clone on the router.
Thus, if you need the MAC address clone or not depends on what you did when exactly after how much time of inactivity when the internet did not work anymore.

How to find MAC address for WAN port for Airport Express 2nd Gen.

The New Airport Express has a LAN and a WAN ethernet ports. How can I find the MAC address for the WAN ethernet port as my Service Provider needs it for provisioning....I can fid MAC address for Ethernet and for two wireless 2.4 & 5GHz but not for WAN ethernet port using Airport Utility 6.1

Many thanks for the swift response. However, there is no WAN MAC address on the box or on the device anywhere. I even used magnifying glass to find one .
The airport utility shows only three mac addresses. One for 2.4GHz, one for 5GHz and one fo the ethernet (LAN port) whereas there is another ethernet port in the device mentioned as WAN port and I am still not able to find the MAC address for the WAN ehternet port for Airport Express (2nd Generation).
Will appreciate a response to make th device work wiht my service provider as providing them the WAN mac address is a must. Had there been an option for cloning mac address, the issue would have not been there.
Many thanks again - in advance.
