MAC address of WLAN router radio

Is there a command to get the MAC address of the WIFI I am connected to?

Here's a script that'll get the mac address of your current default gateway
Which is not necessarily the same as the MAC address of the base station you're currently connected to.
It may be on small residential networks where the base station IS the gateway, but it won't be that way on most corporate networks, nor on networks where there are multiple wireless access points providing broad area coverage and you're trying to discover which access point you're connecting through.

Blocking MAC-Address on Cisco Router

Can anyone tell me how to block a particular mac-address on cisco router 2900 series? There are few pc's in the network which i dont want to get them into the network anyhow. Can anyone help me out with this?
Regards,
Abhishek

With your problem-description
There are few pc's in the network which i dont want to get them into the network anyhow
the strategy of using the router to block them is the wrong way because the PCs are already on the network and the blocking has to be done at the entry-points which are the switches.
But if you want to stop them leaving your network on the router by filtering the MAC, you could also use modified QoS-mechanisms:
class-map match-any UNWANTED-PCs
match source-address mac AAAA.BBBB.CCCC
match source-address mac DDDD.EEEE.FFFF
policy-map IN-POLICY
class UNWANTED-PCs
drop
int GigabitEthernet0/0
description LAN-Interface
service-policy input IN-POLICY

Error in Adding Mac Address in WLAN

Hi,
We have multiple wlan's here in our Company.
Im having trouble with mac addresses which I registered BEFORE via mac filter
and DELETED it after couple of days.
Right now, I need to register this mac addresses again via MAC Filter but error appears below.
ERROR: User name 'xx:xx:xx:xx:xx:xx' is already used as a Mac Filter.
Need to specify unique MAC Address across Disabled Clients, AP auth,
Management users, Network users and Mac Filters
What can I do to be able to register the mac addresses that already removed to our WLC???
Thanks in advance for any help you can offer.

There are two spots that a mac filter is added. You can only have a mac address in only one of these spots. Verify that it is not in one of these spots.
Thanks,
Scott

How to block mac address in 2800 router

sir
how to block mac addresses in cisco 2800 router

Hi,
To block mac addresses you can simply create Mac based ACLs which ranges between
700 to 799
Example:
access-list 700 deny xxxx.xxxx.xxxx.xxxx
access-list 700 permit yyyy.yyyy.yyyy.yyyy
now you can apply it on interface:
int f0/0
access-group 700 in
exit

MAC address filter on router does not work for iOS8

The MAC address randomization feature in iOS8 is great for privacy, but this being the case, I am not able to connect to a wi-fi router that employs a MAC address filter. Is there a way to turn off this MAC address randomization?

I had this problem. I followed the directions to replace the netinfo db's. I rebooted, and started going through the initial OS X welcome stuff. When I tried to re-enter my user stuff, I got a "sorry, standard user cannot be added" error, and the machine went to a blue screen.
This is odd, as I have completely restored the system from scratch (reformatted the hard drives, reinstalled). The first boot up it works fine. It seems that one of the updates must be screwing it up, because after it gets through updating, when it reboots, I can't log in.

I have a Linksys WRT54G wireless router that has a MAC address

A month ago, I could print from my PC and my Mac to my Epson printer over my Linksys WRT54G wireless network. Now, for some reason, I cannot connect and print from either computer. An Epson tech asked me to check the MAC address of the Mac and the printer to see if they were the same. They were not. He then opined that might be why I couldn't print.
I don't know what changed a month or so ago or why it changed. I have not done anything to change the MAC address on either the MAC or the printer.
The Epson guy said the problem might be fixed by adding my printer's MAC address to my router's MAC address. Something about "enabling MAC address filtering". Then he told me that was an issue to pursue with my router manufacturer. Naturally.
Speaking of that problem...someone else had it, too...another technician at another site wrote: "...by default, routers don't come with mac address filtering enabled...and if that's the case....then adding the printer's MAC will not solve any issue that you may be having..."
So, three qustions:
(1) Can I add my Epson Workforce 545 printer's MAC address to my Linksys router? Is that possible?
(2) If I can do it, how do I do it? I saw no "add" or "edit" functions on the Linksys WRT54G Status Page.
(3) What causes MAC address mismatching to happen? What is unstable in that assembly?
Solved!

Mac addresses with different devices will differ. No two devices will have the same mac address. this is also called the hardware address. This is designed so that it will serve as a unique identifier of your devices in the network which you can check thru the router. Now it is possible that wireless mac filter might be blocking it from connecting to the network. But it would be best to check as well and make sure that the printer is connected to your network and has the same ip address segment as your router.
How to check if mac filter is enabled:
Setting up wireless MAC Filtering to permit users to connect to the wireless network on your Linksys...
Setting up wireless MAC Filtering to prevent users from connecting to the wireless network on your L...

Ping problem in the neighborhood and Msan can see the mac address of router

Hi everyone
i have a router 1941/K9 with card EHWIC-4SHDSL-EA ,i have configure this card in my router , the problem is I can not ping the ip @ Neighbourhood and the MSAN can't also see the mac-address of the router do you notice that the interface in the MSAN and in the router is UP / UP
anybody help me

Hi,
An ethernet interface will be always up/up and it goes down only if there is problem between the given port and the connected one. The issue can be anywhere else in the middle.

Lynksys Router requires MAC address

I have a new iPhone and want to connect to my home wi-fi network. I require a MAC address to be put into the Lynksis to allow connection to my network. How can I get the MAC address for my iPhone?

Where do you enter the Mac address in the router?

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.

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.

Changing MAC address on wrt300n

So what did I learn today ... never let your little brother on your PC when logged in at a forum ! Result = kicked out, profile deleted, IP banned !
So I gather that my ISP has only static IP's and they suggest to change my MAC address to get a new IP so I can return to the forum and sign up again with a new profile. So the question is ... how the heck do I change the MAC address on the router ? Anyone have a source that I can read up on this ? This is all very new to me.
Thanks in advance.

MAC addresses are like DNA. There are no two matching ANYWHERE in the world (each device in the world has a unique hexidecimal MAC address and no two are alike). Therefore you cannot change your MAC address.
What I can tell you is what your ISP really means. When you connect your router (which has a MAC address) to their modem, their modem memorizes your devices MAC address and assigns it an IP address. You need to make the modem forget this MAC to get a new IP.
To do this, turn off your modem and old router and leave it off for a bit (10 min). Borrow someone elses router (or if you have an old router, use it). Connect it. Turn on modem and new router. Leave on for about 15 min so that your ISP forgets the old MAC address of your original router and creates a new IP address under the new MAC address of the newly connected router.
After 15 min, power them both down again, disconnect the temp router and connect your original router. Power them back up and wait 15 min again. You *should* get a new static IP from your ISP as it thinks it's a new MAC again. The ISP doesn't remember MAC addresses, only their modem does and once it forgets, it should give you a new IP when you connect the router again.
Hope this helps!!

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.

Import / Export of MAC Address Filters (wrt610n to wrt1900ac)

Can't get past configuration utility to find MAC address

How do I locate my iPod Touch's MAC address prior to completing the configuration utility so that I can add the address to a router's MAC filtering list? It doesn't appear that I can do anything with the iPod unless I first go through the config process...but if I don't have the MAC address, I can't connect to my WiFi.
Any suggestions would be appreciated.
Thanks

With iOS 5, you can setup the iPod via wifi without connecting the iPod to a computer. However, you have connect to wifi to do that. The poster is trying to set it via wifi but can't since he does not know the MAC address to add to his router so the iPod can connect to wifi. That is why I told him to set up via USB and iTunes.

Well, you don't need to add the iPod's MAC address to the router filter table until AFTER you set up the iPod.
Think about it: To set up a new iPod you use the USB/Docking cable to connect the device to a computer that is running iTunes so you can use iTunes to set the device up. During the setup process you are using the computer's network connection to transfer data to and from Apple.
After the device is set up you can retireve the MAC address.
FYI: My home network is set up with MAC filtering....
OK, fine. And what are the chances his new iPod is not running iOS5? (HINT: He didn't add an iOS tag to his post...) And if I read his post correctly this is a NEW iPod because he has to run through the configuration utility.
I'd say that based on a recent thread about a replacement iPod not running iOS5, I'd say the odds are pretty darned good that the OP's iPod is not running iOS5. With that being said, he cannot setup his iPod over a wireless connection which negates the necessity to retrieve said MAC address. He must connect his iPod to a computer.
