HT4262 wds MAc address question

I have a wds network working with
- a time capsule as main
- a n exporess as relay
- an airport extreme as end node
it is working but slow; as I was wondering if there was any traffic between the end node and the main station i ask myselve:
should the remote stations mac address be allowed by the relay only or the relay and the mainstation?
any toughts on this?

it is working but slow;
Unfortunately, that is what WDS does. The bandwidth on the network is cut in half for each relay or remote. Since WDS only runs at "g" wireless speeds, when you have a relay and remote configured, the entire network runs at only 25% of normal "g" wireless speeds. This would be about 13-14 Mbps link speed. The "actual" throughput would probably be around 6-7 Mbps.
I was wondering if there was any traffic between the end node and the main station
It depends on how you have configured the main base station and remote. If you "allow" the remote to connect to the main, then the remote will try to "hop" over the relay, so there would be direct traffic between the remote and main.
If you do not "allow" the remote to connect to the main, then the remote must be allowed to connect to the relay. In this case, there will not be direct traffic between the main and the remote. The main connects to the relay and relay connects to the remote.
any toughts on this?
Avoid WDS if possible

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 Otherwise, when the lease expires and the device is no longer active, the router forgets everything about it.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.

Hyper-V Failover Clustering MAC Address Question

Hello,
Can someone please explain how MAC address assignment works in a hyper-v cluster? I have a couple machines that need to have a static MAC address assigned and want to know how the cluster handles it when the VM is Live migrated to a new host. Thanks in advance.

Hi ice2921,
Yes, after export and import to another Hyper-V host, the dynamic MAC address of the VM changes
after export and import to another Hyper-V host, the dynamic MAC address of the VM changes, this is by design.
As Alexey offered article, to have a dedicated Mac Address for the VMs they should be set to static MAC address, it is normal the dynamic assign to vm when the all the Hyper-v
host as there own MAC address range , this is by design of Hyper V and failover clustering when using Dynamic MAC addresses for VMs.
If you are using 2008R2 Hyper-V failover and you found it often lost the network connection and configuration, please install the hotfix.
Reinstalled the integration services
The network connection of a running Hyper-V virtual machine may be lost under heavy outgoing network traffic on a computer that is running Windows Server 2008 R2 SP1

MAC address question - Solaris Intel

I am running Solaris 8 for Intel and using the Intel Ether Express Pro 100TX (iprb driver) network card and I need to permanently override the card's MAC address. Temporarily, I have used ifconfig to change the card's ether address, but as you know, that's only good until you reboot. The setting isn't in the iprb.conf file (and it's not like I have the luxury of having an OpenBoot eeProm).
If anybody knows, I appreciate your help. - Ken

The Mac addresses in intel cards are burnt into a serial eeprom on the card. So you can't change it. :-)

ICloud to Mac Address Book - Two Questions

Okay, I have learned/accepted that iCloud is not the sync'ing deal that MobileMe was (missed that in the fine print as I have been a loyal .mac user from its inception and like the MM syncing). I understand that everything is updated in the cloud and pushed to various devices (for me, iPhone 4S, new iPad and 2009 MBP). So, how is it possible for my iCloud address book to have more contacts than my MBP address book? Wouldn't all of the ones in iCloud be pushed to the MBP? The only thing I can think is that before I understood the concept that there are two address books resident on the MBP, I starting deleting what I thought were duplicates since I wasn't able to merge them due to two different sources. I could not find a way at that time to tell me which line was from what source. Then, once I get the two address books matching - mostly to ensure that I am not missing anything in the iCloud one - what purpose does the Mac based address book serve? I just had a nightmare of dragging various cards from my iCloud address page on the right into the iCloud group on the left and only to realize after doing at least 20 cards that after the first one, the left page registers back up putting the Mac based group across from the iCloud contact list so I dropped many of them into the Mac group instead of the iCloud group. The iCal doesn't maintain a Mac version and an iCloud version, why does the address book? BTW, all software on all devices is up to date as of this posting.

Please pardon what may be a silly question. This is my first ever post...
I was thinking about deleting "On My Mac" address book per your above instructions, and sticking with the one iCloud contacts. The problem I am afraid of running into is this: In iTunes, when I sync contacts, the groups that show available for syncing all come from "On My Mac". If I delete from the Mac, will that make my "Contacts" icon on my iPad 'dead'? Thereby, forcing me to log onto iCloud to view my Contacts, instead of a handy shortcut???
Or will I simply get to forgo the iTunes syncing... and the "contacts" icon on my iPad will reflect what was synced thru iCloud?
If the latter is true, does that simply mean I will need to recreate my "groups" in iCloud?
Thanks in advance, I certainly need some guidance.

Considering buying time capsule have some Mac address related questions

Hi,
as mentioned above I'm considering buying a time capsule for backup and wifi purposes.
My internet providers connection depends upon a set Mac address from the first computer you register with, the system works with any router which then clones the MAC address and issues a wifi signal to all computers. I don't have access to the origional computer which we registered our connection on, it went to the great computer graveyard in the sky and I have no record of the Mac address.
I Would like to use the time capsule system as a router and remove my existing router. my questions
can the time capsule spoof or clone a Mac address ?
I Don't want to be offline while we deal with technical support as they are quite inept sometimes.
Is it in this case really plug and play ? Can I just plug it in set it up on my Mac and away it goes where other non Apple devices can use the wifi.
Without the existing router the cable that comes into the house connect directly to the ' original ' computer and the Internet only works on that computer
hope someone can help me I would like to purchase this device

The Time Capsule cannot clone a MAC address, so quite simply, the product is not for you.

Networking question; How to use MAC address to find out IP address.

Hi there,
I want to discover the IP address of an attached device (Netgear switch) on my network. I know it's MAC address – can I use this to get the IP address?
Thanks in advance

Short for Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium. Consequently, each different type of network medium requires a different MAC layer.
On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC)
I have a feeling you might have the term MAC Address confused
Depending on the device you are using it may be that you can type in 192.168.1.1 and hit return key, and it will give you the Router Utility and this can give you the assigned IP Addresss to external devices, if the router is used.

MAC address issue...old, but have question

I missed all the news about bios 2.5 but anyway did it screw up the MAC address? I flashed it but it never let me into windows saying I didn't have an acpi compliant bios.
I see some things about it messing up the MAC...
If the mac address isn't all zeros is it ok? Or did the bios just change it altogether to a diiferent value?
Sorry for late post about it...I missed it when bios 2.5 out to do my comp being down at the time.

Is a MAC address filter incompatible on an extended network?

Hello all,
I've bought myself an Airport Express and an Airport Extreme.
The Express serves two roles:
1. Play music
2. Extend my network (a real extension, not just a network join)
On my Extreme, I've setup MAC address filtering with a time-based access (to avoid hacking of my network during the night -- don't worry, I have WPA2 security too...). Here's what I've done:
- All devices: no access from 11 PM to 7 AM
- Airport Express: always access
- Macbook Pro: always access
So far, so good.
Now, the problem I see if the following: IF my Express has access anytime, then an unknown device CAN connect to my network at night (midnight for example) simply because it will connect on my Express instead of my Extreme! It's like an unlocked back door!
So, from what I see, when I extend a network, the MAC filtering is not passed along to the "extending" devices. Also, on an extended network, I CAN'T set a MAC filter... So I'm stuck with an unsecure extending device.
So, my question is the following: is this normal behavior or is this an oversight from Apple? In other words, how can I extend my network and "propagate" my security setting on all my devices?
Thanks!
P.-S. On another topic, but related, any idea how to apply a setting without rebooting the router everytime? This is very annoying.

HI Yes this works fine. I have these  wifi base stations these configurations on the same subnet in my place *using MAC filtering (access control)* in two extended networks.. Here's how I do it.
• AEBS 802.11n@5Ghz 9DHCP and WAN.. and MAC ADDRESSES. TimecapsuleTV = SSID="my5Gwifi" , closed network
• 1 x AEBS 802.11g 2.4Ghz snow coloured dome base station (connected through ethernet to the main 802.11n AEBS) + 2 x 802.11g APx's + 802.11N APX; closed network; name | SSID ="my2.4Gnetwork"; all bridge mode. FOr WDS add all MAC addreses of all devices like iphones, ipods, macs, pea-seas, PS2's etc and the other APX base stations too!.
Here's the deal:
for the 802.11N base stations (AEBS . TC or APX gen 2), the extensible wifi stations are through '+extend this network+" in the + Airport Utility+.. There is no provision for the extension stations to addf any ACCESS control if you use BRIDGE MODE> (as I would you to do advise).
• for the *802.11g or WDS* I have found that you must ADD all the MAC addresses in EACH of the base statsion. This is simple to do my exporting all teh mac address config lists and importing them as you need. THis works fine.
My company registers world wide all laptop wireless nics. We have over 300,000 employees (3 x 10**5) all dynamically VPN'ed adn mac address filtered for windows , linux and unix. it works for them worldwide. Walk into any office and you are connected.
As for me and others WEP, WPA2 and all that is a mess around for hours (with that awful redmond based software) with frustrating and a huge waste of time when some one tries to connect to your system with some of those ghastly microsoft opertating systems. They all have their quirks. Vista - well you mostly know.
In any case the simplest and I beleive effective for most is MAC ADDRESS fitering.
FWIW all ways can be infiltrated.. you just need to monitr your network or add a GBE hub and use cables where the cables are in a locked oom.

I have two .mac addresses; how does this work in iCloud?

This is not about consolidating Apple ID's... I think.
When I got my first .mac address, I thought I picked a good one at the time. Later on, due to the peculiar spelling, I opted for an additonal (paid) address which I use every day. Now the first one (which is an Apple ID) contains my calendars, contacts, etc. I never use the email portion of it, again because of challenging spelling. The second .mac address (also an Apple ID) is an email only account. This is the email account I use daily.
When I make the transition to iCloud, I intend to keep my original AppleID (from the pre-.mac days) as my iTunes store ID.
My question is, what happens with my two other accounts?
.mac #1 with the contacts and such would move to iCloud and sync everything there as it currently does with MobileMe. Since .mac #2 is an email only account, would I even need to bother moving it to iCloud (if that's even possible), or would I just keep using that as email only using the current mail settings on my iThingys and Mac? Does anyone know if .mac #2 will live on after MobileMe vanishes, or will I loose my daily and coveted .mac email at that time?
I'm sure Apple has a good reason for not allowing us to just consolidate everything in one place, but I know there are many out there with a similar situation to mine.
I've spent a good deal of time tonight searching the various threads and can't seem to find an answer to the two .mac email dilemma. My appologies if it's already been discussed.
To sum up, I have one Apple ID that I use for iTunes and intend to keep as such. I have two .mac addresses which are also Apple ID's; one that syncs with MobileMe and one that is email only. I would like to use iCloud to sync what is currently on MobileMe, AND continue to use the simpler email address that I've been using for years.
Am I screwed??
Thanks in advance for your help, and Happy Holidays to all!!

Migrate the account which contains your calendars, contacts etc. first, at http://me.com/move and set it up on your Mac and devices.
http://www.apple.com/icloud/setup/mac.html
Now migrate the email-only account in the same way. On a Mac you can add it in System Preferences>Mail, Contacts & Calendars - it won't sync anything but will be added to the accounts in Mail where you can then use the email in the normal way.
I don't know what the equivalent process on an iOS device is; very likely you need to add it as an account in the Mail app.

How can I tell Apple to store my MAC-address of my Wifi Router in there location DB?

Hello
Recently I bought a new Wifi Router and when I use the Maps App it tells that my ipad is located in China (Shangai)
When I also want to use the automatic timezone feature in the preferences app it indicates that my ipad is in China (Shangai)
I have already searched for a number of discussions (in and out the Apple Support) and their I found that the problem is in a location DB managed by Apple (crowd-sourced database). It seems that my Wifi Router is registered with a wrong location. :-(
my questions :
.- is the somebody that can give me a procedure (certified by Apple) how I can update this location DB?
.- How can I store my Wifi Router MAC address with the correct location in this DB?
Already thanks in advance
Kindly regards

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.

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.

Is there any way to track a stolen laptop using the mac address, or by triangulating the wifi, or even by checking to see if the macbooks serial number has been registered online anywhere?

A little info on my question,
I had it stoeln on June 22nd 2013. I had recently bought it so had not installed any software on it nor did I have registered with icloud. I had contacted police, registered it stolen with Apple (but then just discovered this week that apple do not have a database for stolen products, which makes no sense at all).
I have contacted all the major pawn shops and computer stores in town etc etc. I have recently discovered that each laptop has a unique MAC address whcih begs the question, is that traceable somehow? I have been made aware that the router strips the mac address before it connects it to the internet but does the isp log the laptops MAC address? If i contacted all the major isp in my country would they have the ability to search for the mac address of my latop and then link that with an ip address?
Any help would be great please!

Yeah but I registered it stolen with Apple first thing, then called local police etc. Apple told me on the phone that the serial has been logged as stolen, which I assumed would limit the computers use online.
Every machine has a unique serial number what I was getting at is there must be some way to track the serial number and for example if the theif logged onto facebook using a stolen machine, if there were a register of stolen equipment then red flags would pop up, you know what I mean?
Well, I hadn't heard of that before. If it's true, then what you say should also be true but the Mac would have to publish its hardware serial number over the Internet and I haven't heard of that either. The only Apple tech that is supposed to constantly track you is iCloud.
You said you assumed the database would limit use online but if that's only an assumption, you need to ask Apple what exactly the stolen database does. It is possible that the serial number might only get flagged if it comes into an Apple Store for service, if it ever does. You need to clarify this with Apple.
