[Q] Wifi MAC address changed, or missing!?

My wireless has a MAC filter enabled.
I installed the EOS ROM that had a bug issue about wifi... My wifi wasn't working, however I could see the SSID. I then installed another ROM and now the WIFI service hangs when starting. I happened to look into "About Tablet" and see that the wifi did not have a MAC address! I reflashed a few times, formatted all the partitions, but still no MAC address. I reflashed the EOS ROM and now the wifi works, but wouldn't connect. I looked at the MAC address and was comparing it to the ones on the filter and noticed it wasn't listed in there.
I am beginning the EOS ROM somehow nuked my MAC address or something, and the ROM may have one baked into it. That's the only thing that makes sense since I have no idea how the MAC address would just suddenly change.
I need help fixing my TF101's wifi MAC so I can use another ROM that's more stable...

I did not check this when I was running the Team EOS ROM but I did notice that my router was not serving my proper IP address per the MAC Address. I did not think to check it there, but I flashed back to Revolver 4 beta 1.3.1 and my MAC address is back to where it should be.
But, obviously Team EOS ROM did change my MAC address if my router gave it a random IP address.

I think I can explain this, give me a few minutes.

wifi driver is reading nvram from /system/etc/nvram_nh615.txt (/system/etc/wifi/bcm4329.cal in TeamEOS Builds) which has no mac address defined.
the solution is to make the driver read it from /data/misc/wifi/nvram.txt and use wifimacwriter to write the real mac to that file
It's already fixed in my CM9 build

Cheers, it will be fixed in the next nightly.
Edit: What am I missing? I don't have /data/misc/wifi/nvram.txt unless I run a stock rom

I think I found my problem. wifimacwriter looks for /system/etc/nvram_nh615.txt
so my /system/etc/wifi/bcm4329.cal needs to be changed in my configs.

1. Yes, you can change MAC address (for example if you install CM or MIUI your MAC addresses will be changed). But I don't know how to do it (There are several applications but they don't work for some reasons)
2. I don't think that it's unlegal because it's easy to change it on PC, and the our device is already small PC.
It's unlegal to change IMEI.

LOL! Do you know that MAC can be changed very easy? look this and here Unfortunatelly those scripts doesn't work on our device
Also when you flash CM7/MIUI/CM9/MIUI2 the MAC became 08:00:28:12:03:58 (yes 1 MAC for every owner's of i9003 that flashed those ROMs). This happens because Samsung put the same MAC into hardware and change it manually in their stock ROMs.
BTW, if you flash back the stock ROM, the MAC address will return to Samsung one
PS: If you don't know the subject don't try to teach somebody: he can know more than you.

Well, a cafe store near my house open wifi for free, but somehow, i couldn't connect to it, maybe they block the recent MAC address that connect.
I saw in busybox iplink tiwlan0 has the MAC address, maybe it related to something?? :->

I know only 2 types of cafe WiFi policy:
1. WiFi under the password: The device can't receive IP address at all. And the customer should ask the password from waiter.
2. Free WiFi: The device can register with WiFi network and can get IP address. But all http requests are redirected to special page where customer should put the password and click button (or there is just button without passphrase).
Also I don't think your MAC is blocked
BTW try to change the MAC with the following command:
su
busybox ifconfig tiwlan0 hw ether 00:11:22:33:44:55

Yup, the first Wi-Fi policy is the same, but the 2 isn't.This Wi-Fi is popular in many cafes in my country, guest just have to obtain the IP address and doesn't redirect to another page.
I tried your following command but is said command not found after the last command (or i did the wrong way ^^! )
p/s: sorry for the bad English =]]

[Q] Mac spoofing

How do I spoof a mac address on my OnePlus One?
It seems to be impossible. The usual apps fail and so does a manual ifconfig shell.
Anyone got a clue on this? Help would be really appreciated.

SOLUTION!!
Ok, i've been searching for month how to spoof MAC address on our device, but anybody helped me.
So i've tried all possible steps to change the MAC address and finally i've done it!
Here's the procedure i've followed:
1. (Requirements) Have a rooted device. (i don't know if busybox is required but in doubt, install it)
2. Install a file manager (Root explorer reccomended)
3. Go in settings, wifi, tap the three point at bottom right, advanced, and disable "scanning always avaible"
4. Open Root Explorer and go in this directory: /sys/devices/fb000000.qcom.wcnss-wlan and you'll find a file called: "wcnss_mac_addr"
5. Open "wcnss_mac_addr" with text editor
6. you'll see only your current MAC address. You can just edit it (edit only last digit recomended) and Save changes.
7. Disable and re-enable Wifi, and you've just edited your MAC address! Enjoy
Important: The Mac address will restore as default everytime you reboot your phone.
sorry for the basic english because i'm italian, if you have any question please ask me.
I hope i've helped you.

[Completed] Mac Address spoofing And authentication problem

After Rooting my sony Xperia Z and got root access and tried to change my mac address with the traditional way ( busybox and terminal emulator ) and with mac address applications too. Everytime it says that my mac address have been changed i can't connect to my wifi network again i don't know why, it says : " Authentication problem " can someone help pleaseeee i have 6.0.1 Android.
thanks in advance

Hi !
I don`t really understand why did you changed the mac address and also I am concerned about how successful this attempt was
In order to do that there`s a set of permissions to be acquired , if you don`t know how to do it , you better restore to default
You can have a look at this thread
Good luck !
