Can't change MAC address

hello, i have a recently purchased vostro 1500, with the standard DELL WLAN 1390 mini card. i have tried many programs, as well as using the registry. nothing has worked. sometimes the program says it has been sucessful, but after i type getmac into the command box, the mac is the same. i have vista. thanks for your help.

 

Sorry for my ignorance, but I always thought that the Mac address was what uniquely identified a notebook and that it was not meant to be changed. I'm probably wrong though.... can anyone correct me on that?

 

Some wireless card vendors allow you to change or set a user-defined Mac address. The default one is hard-coded into the wireless card, but the user-defined one can be changed in Device Manager. Go select properties under your wireless card in Device Manager and you should see an option in one of the tabs called Locally Administered Mac Address.

Now only some wireless card vendors allow you to do this. My old laptop had a Broadcom card and it allowed me to change it. But my current one which has an Intel card does not allow it.

 

What OS are you running?

 

i am running vista, and i have tried the locally administered mac address, it allows me to change it in the box, but it doesnt actually change it. and a mac address is unique to the network adapter but you can spoof it quite easily.

 

I forgot to mention that that method didn't work for me in Vista. I think it has to do with the new drivers that were included.

Its a long shot but why not try ipconfig /all in the command line after changing the Mac address using other programs. Maybe getmac just returns the hard-coded one.

 

ipconfig /all shows the same mac address, thanks though

 

Do you have the Dell Wireless LAN Utility installed?

Why do you need to change your MAC address?

 

The problem is vista, I have a m1330 dual boot with xp and vista. With the dell WLAN utility you are able to mask the MAC address never change it. Vista however, does not let you mask the MAC address. There is no way to change the MAC address.

I needed to mask the MAC address because at my university they seem to occasionally block my wireless access. I think because of too many incoming connections.

 

I'm having the same troubles. I need to spoof my MAC address but none of the usual tricks work. My set-up is Vostro 1400, Dell Wireless, Vista. I'm almost 100% certain it's the Dell card now. The program I use (MACmakeup) works great on my other laptops with Vista/XP. I'm thinking of buying one of those Intel 3945 Wireless cards on eBay to see if that'll work.

 

hi,

running XP here, and as i use my Laptop with a gigabit Ethernet from time to time, and the other times, i run a wireless, it caused problems as my router is set to screen and allow only specific MAC addresses (and the lan card/ wireless card has different lan addresses).

i managed to alter my wireless card's MAC address by going to device manager, finding the wireless card (an INTEL 3945 A/B/G in my case) and changing a setting called "Alternate address" (in the same section as changing the wireless mode / power consumption for the card/etc). the default for this field is 000000000 or <blank>, if you change it to the MAC adress you want, your card should automatically use this alternate adress over the build in hardware one.

i've found that it's occasionally hidden within different parts around the device profile, so click about till you see it, it might also list it as "MAC address" or "Alternate MAC address", as i've found with some older wireless cards.

then again, that's all using XP, it might be different within Vista.

 

Yeah, that's the wireless card I was thinking of swapping out my Dell card for. Now that you confirm MAC spoofing works though I'm definitely doing it. Also, the locally administered MAC is in Vista too it's just that the Dell card is immune to it.

 

I need to change the MAC address for the wireless adapter also, I could not find any sollution though and neither did I find an alternate mac address thingy...

 

You Can Use this 3rd Party tool to you're Mac ID bro

 

The manufacturer list is crap ,INTEL PRO WIRELESS is not in there. And I chose a random one, didn`t work..I did disable/enable the adapter, but no good :|

 

Since your doing things the University does not like or allowed on their network this thread needs to be closed. It's a violation of forums policy.

Play by the rules and you want have any problems.

 

What?no, I need that because my home internet is shared between me and my brother, at different hours,and the internet is linked on the MAC address,it`s why I want to change it to that of my brothers`.

 

Install a router and let handle the clone MAC address.

 

This is what I was referring too.

 

Right.
Well still, can`t you change the MAC address just like the one on the network adapter? I mean, isn`t there a line in the registry editor that can change it, just as you can for the ethernet adapter thing...?
There must be a line there were you can do this...
For the ethernet adapter,I just go into local machine,software,microsoft,class,...0000 and then look for where a specific key is placed,create a new string Network Address and poof , that`s it...
