Ez-B V4 Mac Address

does anyone know how to find the MAC address of the EZ-B V4?

Someone is hijacking Nomads network so I am implementing MAC filtering. If I could get the device on the network, I would be able to see the MAC, but as soon as I unlock MAC filtering, the AP gets compromised.

Please let me know if there is any way to find the MAC address while in AP mode on the EZ-B V4.

Thanks David

The router should show all devices connected to his router - usually dhcp client view

If he has a password on the connection, they can't hijack it

#2  

He does have a password and it has been changed a couple of times and it gets hijacked in a couple of minutes after changing the password.

Dhcp isn't assigned from this ap and he doesn't have rights to the router to see the dhcp attached devices.

Is there something that will display the mac or is it printed on the wifi radio in the device?

d.cochran... I am no network guy, so forgive my ignorance... But how are the hijackers getting around (or getting) the password?...

#4  

there are plenty of programs that will brute force a password.

One thing you can try is to unplug the router from the internet completely remove the routers antenna and then hard wire the pc to the router to log into it and change its settings with out some one cracking it rite away

#6  

trying to figure out how I am going to do this but will figure it out. logs will be my friend probably.

I stepped away from some lunch. I left the connection up and locked down so hopefully the guy has moved on to a different target and I can get the MAC addresses and get them assigned. Nomad has some neighbors who are not very nice at all when it comes to Wifi.

I will update when there is a solution. I had hoped to have JD configured by now but we haven't even started on that part yet.

Wolfe, we have been configuring the router with it wired directly to the laptop. as soon as I put it on the network, the attacks begin. all good. I will figure something out.

I will probably do this again and enable DHCP on the router, which will allow the ezb to connect to the ap, but not the network, and then I will be able to get the mac from there.

#8  

If it was me, I would see if you can get there IPs and report it. but with software today, they probably have a server setup to change there ips.

Ahhhh... the trouble of todays technology.

Even with there ips there is nothing that can be done about it the law has no say as it is completely legal if it is not a government computer:(

I looked into that a few years ago to see what the laws about using some ones wifi with out them knowing

does he have android device?

if so install fling##### fing not fling this will give all device connected to a router or ap. maps a lan. j:D

p.s. connect android first To wireless router or ap, then start fling. p.s.s this will ip and mac address, enjoy! p.s.s.s I have other tools. jad

Can you give a goigle play link to the "fling" tool you suggest? Just searched Play and hundreds of apps come up and none on the first few pages are network tools.

@Alan... I think it is called Fing... I have a version on my android phone...

edit I see you already found it...

#15  

all good. we got his network way locked down. I hate having to do this but it is working for him now.

Thanks for the suggestions.

Also, his JD is at about 90% now. i will connect back up tomorrow to complete.

need some Aluminum foil (like Reynolds Wrap heavy Duty).

Make a shield from the other apartments around the AP and aim it only to device that is attaching to the AP. This will also direct all signals from AP in that direction.

If you ever need to make a cheap signal booster, this works too.

I would have built a Yagi and blasted him, but that would also be unethical.

All good, its working great now. Using technology to defeat technology attacks is fun. also, the attack was coming from below most likely. He would have had to walk on aluminum. thats no fun. it could have been coming from another building also. in any event, it isnt happening now and he is happy.

Another way to get the Mac address of local computers us to use a windows machine and do this:

  1. open cmd command prompt

  2. ping the IP address at least once

  3. type ARP -a

You will see the Mac that matches the ip

#19  

Right DJ, but that doesn't give you the mac address of the EZ-B that isn't on the network yet. You can't ping it if your not on the network yet so its not in the ARP cache yet. The only device he has that is able to connect to the EZ-B in AP mode is an android phone. Well, he has an iphone 4 too, but we didn't try that.

Anyway, I wonder if in a future release of the firmware if you could include the MAC address in the webserver that is in each EZ-B. Just a thought, but it would be very helpful in some crazy situations like to one I helped Patrick with today.

Yes, you would have to connect to it.

Otherwise, the default SSID of the WiFi when in AP mode will have the MAC in the name
