I rooted my phone but since rooting it ive got no wifi it just says error when i check the ip address and mac address they are empty. Have i managed to break the wifi or have i just corrupted some settings and how do i reset them without doing further damage i can get into clockwork if that helps ??
So, here it goes.
My goal is to connect to a network using certain MAC address. Wanted network is marked with "open" and I know that it allows access only to certain devices (according to MAC) on which the administrator have gave a permission to. Once your MAC passes the verification, device gets connected to the network and then I'm asked to enter username and password through WEB browser (well known for me, because it is a procedure that I do on my other device, as well as all my colleagues do).
For example, I was allowed to provide one personal MAC address to administrator to connect to this network. I would like to set the MAC address of my other personal device and set it on my I9195 so that I can access the same network.
So, what have I done so far: I9195 is rooted, it has Android 4.2.2 on it and Busybox installed. I have changed MAC on it using following apps: MacChanger (blue WIFI logo), MAC Address Ghost (green ghost logo), using Android Terminal Emulator commands and via MAC Spoofer (black circle with green text logo). What can I conclude: As soon as superuser has granted the access to these apps, all of them manage to change the MAC. I've done the verification using Terminal Emulator. I also have to add that the MAC remains original if viewed from WIFI advanced menu BUT this shouldn't be an issue because:
1.) Colleague of mine is using his S4 (rooted etc.), while using MAC Address Ghost that does not change the original address (viewed from WIFI advanced menu) but he manages to make a spoof (verified from the Android Terminal Emulator, as all of this apps actually do) and he manages to connect without any problems in the same way as I connect with another device that I have!
2.) I had time to make a small test at home which put a light on the idea that the problem should be focused on the Samsung (and not on the router, especially because I am unable to modify anything on the router on this facility, not even restarting it). My home network works in a similar way as the network that we are discussing about. My S4 Mini has been included in it with his original MAC and it connects to the network without any problems. My other device is also included to the network using its MAC (the one that I am using for spoofing). My other device is turned OFF, router has been reset and I am normally accessing the network with S4 Mini. Then I run the MAC Address Ghost to spoof the MAC on my S4 Mini. In that moment, I have lost the connection that I had which means that the MAC spoofer actually did something. I tried to reconnect to the network but then I am asked to enter the password for my network. I have checked and re-checked it many times, tried to forget the network and doing it all over again but it does not accept the CORRECT password. Changing my MAC back to the original one connects S4 Mini back to the network, while accepting the password immediately.
Problem is represented in a way that it either says “saved” and does not connect to the network or every few times displays a message “Authentication error occurred”.
I have tried I would say every possibility that I’ve seen over the internet. That includes:
1.) Installing WiFi Connection Manager (it provided some info regarding the network that I wish to connect to: IEEE 802.11g standard, 54 Mb link and CH:11). I’ve used its function to fix the WIFI (advanced fix (root required)) but it didn’t help.
2.) All sorts of staying close to the rooter, while enabling and disabling the Power save mode (accessed via *#0011# command) or while having GSM signal.
3.) Browsing through system, data etc. folders to try to find the file that contains the MAC address information (like it did on older android versions in the nvram file). I’ve been unable to find this file or any sort of file that displays my MAC for the purpose to modify it.
I have a plan to upgrade Android to version 4.4.2 later today and make a test.
Please, feel free to suggest anything else! If I do not succeed, I will have to replace my S4 Mini with something else.
Kind regards,
QUICK REPLY: After installing CyanoGEN MOD 4.4.2, the problem remains!
I think there could be a shorter solution! On Sony Xperia Acro S with 4.1.2 Android it was just a matter of changing the MAC address within the file data/etc/wifi/fw! One minute modification...
So, please, if somebody knows the path to the file that contains MAC on CyanoGEN MOD 4.4.2 or on Android 4.2.2, PLEASE HELP!
Kind regards!
Hi, is there a way of changing the mac address of the s4 mini (gt-i9195)?
I am on Stock Rom 4.2.2 and tried some apps from the Play Store ( MacMan, Mac Address Ghost) but every time I change the Mac Address I can't connect to my router anymore. I always get "authentication error"

Backup your EFS. Next you can edit the file under efs which holds Mac adress info.
Not tried, just a suggestion
Edit: The file is "/efs/wifi/.mac.info" on my device.
thank you very much. It worked :good:

Why stop it? Its a security feature that makes your device much harder to track down.

Hey XDA!
just a quick question. Has anybody been able to connect to a wifi network after changing your MAC address? I've tried it on Oxygen, Hydrogen, CM13 and it's always the same, as soon as I change the MAC if I try to connect to a network it will stay at "obtaining ip address" and never connect unless I change back to my original MAC. Any help or input would be appreciated, thanks.
