My router doesn't accept my MAC address

Hi.
I'm trying to set static IPs on my router (Netgear DGN 2000). I go to the "Connected devices" panel, and among them I can see my iMac. Its MAC address is odd ( like c4:2c:xx:xx:xx:xx). As I try to set a static IP, I get an error saying "Invalid MAC address". My other non-Apple devices all have MAC addresses starting with 00:xx:xx:xx:xx:xx and I can assign a static IP to them. Ihave the same problem with my MacBook.
Is there something wrong with the iMac? Or the router? Or both ?

I'm glad to hear that, Thanks
But I checked and there is no update for my router... Maybe I'll write to Netgear support, I would rather not buy a new router just to fix this problem!

Change the password on that e-mail account. It's possible that your account has been hacked/spoofed and spammers have used it to blast out junk, leaving you to 'pay the price'. If it's one where you can contact the company, contact them and ask them what's going on. (if this is g-mail, yahoo, hotmail, don't bother, there's no way to contact any sort of support)

Actiontec router not accepting new mac addresses

I have the Actiontec MI424-WR Hardware revision D. I have put MAC addresses in the router before and all those devices are working fine.Now it seems I can't add any new addresses. I am using WEP 64/40.
Tried the powering it off deal, no luck. Anone know why this is happening?

First an obligitory ... you really need to upgrade to at least WEP 128 but preferably WPA2. Wep64 is very weak. Additionally, understand that Mac address restriction is almost as much a myth as "turning off SSID broadcast" in terms of providing any additional security. The first packet that traverses your network gives anyone who wants to spoof a device which is allowed on your network the information they need to defeat Mac locking.
In general Mac locking and SSID broadcast hiding provide no real security and just serve to make your life more difficult.
With that said ...
I've seen that happen and one way I managed to fix it was to turn off Mac locking and apply it. Then come back and re-enable it and add the necessary systems. Failing that, I've emptied the list, turned off the Mac locking, applied, and then re-enabled and added everyone back it. A pain, but it worked.
Two other things I've occasionally missed myself:
1. New addresses get added to the bottom of the list initially (i.e. you may need to scroll the list box down).
2. After applying, I've seen the list order change -- so the Mac may move to somewhere in the middle of the list
3. Attempting to add an address twice doesn't work (i.e. make sure it's not already in the list).
Sounds silly, but I've done each of these myself at one time or another and kicked myself when I finally realized it.
Hope one of those works for you.

Router MI424WR - Device Names to MAC Addresses Question

I have Verizon FiOS with an ActionTec MI424WR Router. I have many devices connected to it on our home network: ipods, ipads, nook, kindles, laptop, roku, and a desktop.
For each device, I found its MAC address. Then I logged into the router and went to "My Network." There, I renamed each device (for example, from "android-alsdfjl3kljasdf" to "JonKindle" and "new-host-4" to "MaryIpad"). That way, I'll be able to go to the parental controls rules screen and assign each device to rules as I like.
Problem:
The names keep changing back to "android-alsdfjl3kljasdf" and "new-host-4". Not only that, but somehow, the MAC addresses keep changing. Is there a way to keep that from happening?
I thought MAC addresses were assigned to a piece of hardward and didn't change. Can someone please enlighten me?
Thanks,
smy

The trick to make the [name, MAC address] permanent is to assign a static DHCP lease to each device. Otherwise, when the lease expires and the device is no longer active, the router forgets everything about it.
As for changing MAC address, you are correct, they shouldn't change.
If you have multiple "Android-xxx" devices they may be coming up in a different order, thus creating the appearance of changing addresses. Make a list of every active MAC address and attempt to correlate it to your devices. The next time you think one changed, look and see if it's on your list.
MAC addresses can be changed by the user on some devices, however this is typically only done to "play" with a network or circumvent security features.
Good Luck.

US iPad doesn't accept UK billing address details

I bought my iPad from the US but I live in the UK, so my billing address has UK postcode (includes letters and numbers). However whenever I try to buy something from the Appstore, the ipad asks to confirm my billing address on my appleID and by default asks me to change my postcode to US format (00000) and add a US state. Therefore my credit card payment doesn't go through as I have to put in a dummy postcode/state...
Could this be because I originally got my appleid when I used to live in the US? Is there a way to fix this? Should I get a new appleID and reset my ipad? Thank you!

Have you tried logging out of your account by tapping on it in Settings > Store and then logging back in ? Have you also checked that your full address details are correct on your account ?

WRT610N - Reserving a specific IP address for a given MAC address

This is the first router that doesn't allow this. I have to set up a computer to get an address using DHCP then I need to use that IP address and related info to set up a static IP address. That's just plain dumb. Then if I take a laptop to another location, I have to fiddle with setting up for DHCP again. Then When I come home, I have to reset all the settings on the laptop to do the static IP thing. If you move the computer around a lot, that's a lot of unnecessary fiddling.
Why not just have the router keep a table of MAC address and the IP address assigned for those computers. It would be a lot easier to configure the router once than reconfigure a compter a whole bunch of time. It's not rocket science or brain surgery. A lot of other routers do this and allow the user to set up reserved addresses

You may have stumbled over a known bug!
What you want to do is click on [DHCP Reservation] on the Basic Setup page and assign the Ip address based on the MAC of the connecting device.
But there is a bug! The JavaScript code generated in DHCP_Static.asp puts an extra space in a few Array definitions which result your browser not properly rendering the HTML code. So you get a window that is intended to allow you to manage the Ip assignment based on MAC, but the page is BROKEN.
(Right click on the page a select "View Source" from the context menu and you'll see something like this.)
===================================

===================================
I believe that blank line between the last entry and the final ");" is causing the problem. At least in every browser I've tried, a JavaScript error is generated at that point with: Message: Expected ')'
My guess is the router work fine. But since your only way to communicate with the router is via a web page that is broken, you can't make the changes you want to make!
I was told by Tech Support that they know of this issue and are working on a fix. I was also told....
:: Since the problem you have is regarding the DHCP Reservation, we will escalate
:: this case to the Case Management Team Irvine.
and...
:: We will escalate this concern to the Headquarter and a Senior Technician would contact you within 48 hours.
We'll see... I'm not holding my breath.

WiFi issue with MAC address

I've been using MAC filtering as part of my home network wireless security for years. This means inputting the MAC address of every device and computer that I want to have connect to my network. So I get my new WiFi + 3G iPad on May 28th and look in Settings to find the MAC address so I can input it into my router info. The router (D-Link) says that it's not a valid MAC format, presumably because it begins with E8 instead of the 00 that all my other devices have. I ended up having to disable MAC address filtering in order to have my iPad connect to my WiFi network. Does anybody have any comments or ideas about how I can get the router to recognize a MAC that begins E8:06 etc.?
Would appreciate any help. Thanks.
Glenys

I am using MAC filtering on my network using a Linksys router (WRT300N) and had no problems adding our iPad to the MAC table. Also, if I'm not mistaken, the first portion of a MAC address is unique to the manufacturer, so unless all of your wireless devices are from the same manufacturer (at least the wireless component of the device), then it isn't likely that all of your MAC addresses will start with the same digits. Make sure when you enter the MAC address that you include the colon in between each pair. My Linksys won't accept the MAC address without them. As someone else recommended, you may also want to see if there is a firmware update for your router that addresses this issue. Good Luck.

How to get MAC Address of a stolen laptop by using Serial number?

Hi my Lenovo G560 laptop was stolen on 17/04/13. I have the serial number. In order to trace the laptop, I need the MAC address. Unfortunately I don't know the MAC address of my stolen laptop. My question is, is it possible to get the MAC address by using serial number?
Serial Number: xxxxxxxxxx
Moderator Note; s/n edited for member's own protection

hi Subrahmanya,
Sorry to hear about your trouble. Unfortunately, the only way to get the MAC address is to run a query on the unit (physically or or remotely). Using the serial number to query information on the system will list the devices that are included on the unit (this doesn't include the MAC address).

ACE How can we do a static arp to multicast mac address?

I have a architecture that uses ACE to do Firewall Load Balancing. I need to add a static map of a VIP IP to a multicast mac address (Microsoft servers with NLB in multicast mode). The ACE does not accept multicast mac address in the static arp statement, anybody knows why? Is there any other way to do that?
Regards,
Artur Pinto

Hi,
The ACE doesn't support multicast MAC addresses. This is a limitation impose by the hardware used on the boards. Syed has previously proposed a workaround at https://supportforums.cisco.com/message/464174#464174 . I don't know if that will be applicable in your case.

Router cannot get a WAN IP address form ISP (e4200 v2)

Hello,
I just bought the Cisco e4200 v2 router, I did all the installations as the Cisco connect software instructed me and everything went fine.
After the installation I configured the router on the WAN settings as (Automatic Configuration - DHCP), like my old router (Linksys WRT54GL) and I saw that my router doesn't get the WAN address from cable modem from my ISP(it stays on 0.0.0.0), it doesn't renew the IP address.
So please how can I fix this issue? This is a bug in the e4200 v2 firmware?

EVERY time you change what is connected to a cable modem you MUST power cycle the modem. If it's a telephony modem it has an internal battery so you have to push the reset button, usually with a paper clip, to reset it.
Cable modems memorize the MAC address of the first connection and block all subsequent MAC addresses.

MAC address and wifi

I just bought a MacBook Pro. It was set up at the shop.
When I brought it home, the MAC address showed up as f8:1e:df:e2:d6:71
My Dlink router says it is an invalid address. I've never had the problem with my other Macs and iPod Touches on my home network.
Any idea how I can make it a valid address?

The home network has MAC filtering because our connections seem to drop out from our router all the time.
Very strange that my Airport iD starts with f8 as all my other computers (PC and Mac) and ipod Touch are all 00 addresses.
So I am concluding that
1) I cannot change my MAC address.
2) My dlink cannot accept my MAC address.
I am currently spoofing my address. Which is heaps annoying because I have to go through the process of changing it everytime I turn on my computer.
I have yet to try this Mac on other wifi systems. But I hope I won't run into any trouble with wifi that might need my MAC address.

Can't change MAC address of my wireless card on Windows XP

Dear Forum Members,
I have recently bought a notebook, Lenovo IdeaPad G550L (I haven't found section for the G series here on the forum) and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly changed MAC address. I installed the recommended driver, available from Lenovo's website, version 5.10.38.14. I tried the common way to change the MAC address, went to Control Panel -> Network Interfaces -> Broadcom Wireless Network Adapter -> Configure... -> Advanced -> Locally administered MAC address, and changed it to a different address (without ":" or any separator characters). Unfortunately this common solution won't work at all. Although, no error messages are produced when changing it (so it seems successful) my wireless router shows me the original MAC address of my integrated wifi card. Tried to restart my computer, my router, everything.
* Tried different drivers, downloaded a driver from HP which had a separate wireless configurator, Broadcom Wireless Utility. It worked like the driver from Lenovo (except this one hasn't got the utility), but I was still unable to change my MAC address.
* Tried a different driver from SoftPedia, version 5.10.79.14 (this is newer than Lenovo's), it didn't work either.
* Tried Nathan True's MACShift utility. It seemed to change the MAC address, but my router showed the original, so it didn't.
* Tried to look for official Broadcom drivers on www.broadcom.com but found nothing for BCM4310.
* Finally, I booted my alternative OS, the latest Ubuntu Linux, and used the kernel driver b43 for my wireless adapter. I tried to change my MAC address using the command ifconfig wlan0 hw ether .... and connected to my network. It worked, my router showed the changed MAC so the hardware (or the firmware) is capable of doing this by the right driver/firmware.
I tried to address Broadcom with the issue, sent them a letter like this post they replied that they are not competent, they wrote the following (I guess this was an automatically generated message because it got back in 10 seconds ) from [email protected]:
"As the chipset supplier, Broadcom provides driver support to our customers - the manufacturers of wireless devices - that ultimately provide products to end customers, such as wireless LAN vendors, cable modem vendors, and notebook providers. It is up to these manufacturers to provide product-specific drivers and software support to their end customers. Please contact the manufacturer of your wireless device for their current drivers"
Then I addressed Lenovo with the problem, their answer:
"Dear ******,
Thank you for contacting Lenovo, the makers of ThinkPad and ThinkCentre products. As I understand, you have purchased a Lenovo IdeaPad G550L and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly change MAC address.and you would like to know is there an official driver for Windows XP that allows you this basic feature like b43 in Linux. We apologize,Please do speak with our Idea pad technical Team at 877-453-6686 Option 1-2-1-2 for further assistance.
If you have further questions or concerns, please feel free to contact us at 866-42-THINK (84465) option number 2. We will be happy to assist at that time.
Once again, thank you for contacting Lenovo.
Sincerely,
Lenovo Websales/CustServe"
So this means I should call them and spend extra money for phone bill of international calls because of their fault of providing a basic feature that is to be expected from every single wireless card in the market. Should I believe that a guide over the phone is more efficient than a step-by-step solution or a link to an alternative driver? I'm getting kind of disappointed. At least they have understood (or copy-pasted) my problem, dutch comfort though.
Any ideas? Anyone experienced the same problem and solved it? Is there an official (or even unofficial) driver for this device for Windows XP that allows me this basic feature (like b43 in Linux)?
Thanks in advance,
str4ngS

Yes, I have posted this thread to different forums after I realized that Lenovo "customer care" is not likely to help me out and even wirelessforums.org members couldn't come up with any ideas for days, that's why. I have already written that helper applications like SMAC (or etherchange or macshift) don't work, because they do the same thing in the system as I change it in the driver panel, so they use the same method which simply does not work.
Locked? Definitely not. If yes, why can I change the MAC of my adapter under Ubuntu Linux using b43 open-source driver if it's really locked? Or you mean it's locked from software, because Lenovo or Broadcom didn't want their users to change their MACs or they just forgot to release a fully-functional driver? Well, then I would like to have a driver in which it's not locked, because this is a basic feature of my adapter of which the hardware is capable.
I have already contacted Broadcom, see their (automatically-generated) answer in my initial post, but I will try to do that again with more foresight.
