Hi guys,
My question is like this: is is possible to remove or password protect (i.e. locking) WiFi capabilities on an android device (rooted or not)?
I know this can be achieved through renaming a driver file, though I am not sure which one and one would need a rooted phone after all.
The best option is of course locking WiFi with a a password...
Please do not ask why, as it is a pain to explain...
~confuded
P.S. The user ha no idea if his phone is rooted or not, or how to access the rooted filesystem, or how to rename system files (or which ones).
Hi everyone!
Yes, I am a noob...
Infos:
I already know that every Android device needs a new "wpa_supplicant" file for connecting to Ad-Hoc Networks e.g. created by my Nokia's JoikuSpot or sth. else...
If there's another option, tell me
Also I've heard about this application:
https://market.android.com/details?id=com.jrummy.root.browserfree
that supposedly can be installed on an unrooted device!
The question:
For me it doesn't make sense, that you can install an app which has access to all files without rooting the tablet at first.
Can I replace the wpa_supplicant without rooting and be happy with tethering 3G from my phone to the tablet?
AdHoc Networks are my only cause for rooting but it seems to be quite difficult, maybe no one did it already with the slate ... I can't find instructions to do it anyway...
Please HELP

Hi guys i have a problem with my IP address when i go to settings>about phone>status my IP address says unavailable ive tried switching my phone off but nothing works i think this is affecting my wifi as well because it also says settings not responding when i switch it on and when i use other applications to switch it on they fail when they are collectiing my wifi address someone please help me i miss WiFi:crying::crying:
Since you didn't post the device information (ie phone model) nor the router you use, it doesn't allow us forums users to give you the best options to troubleshoot the problem your having
Some generic options to try
1) try powercycling the router (linksys have a tendency of dropping Wifi connections)
2) check to see if the wifi toggle is on (the settings menu)
I have the same problem as well:
my phone specs:
Software version: L720VPUEMK2
Device model: SPH-L720
Android version: 4.4.2
A couple of days ago i had installed the newest update for the s4 and when it had finished installing both the bluetooth address and the ip address said unavailable and i am now unable to connect to any internet

It looks like your efs has been missing.If you have a backup.Restore it.
Flash the modem separately may help too.

if you r having problem with efs file then try this.
1> you need to root your phone first. check out forums there are tons of tut's available.
2> goto this post and download efs professional zip.(you have to extract it)
3> enable usb debugging in developers mode and make sure you have all the usb/adb drivers installed on your phone.(install universal adb drivers that will work fine)
4> open efs professional.exe and connect your device.
5> now go to backups tab and select your device under device filter tab and then click backup. wait for backup to be complete.
6> now go to restore tab and under backup archives select one of the .tar.gz file I prefer (device)(although it doesn't matter) and hit resotre.
7> your device will reboot and you are done.
if you still have the problem
download root explorer and goto efs folder in root directory. then find this file - 'nv_data.bin.md5' and delete it and restart the phone.
if this helped then hit the thanks.

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.
Same problem
I need to spoof MAC adress on my OPO, i've tired all the apps but everytime the MAC seems changed succesfully but when i try to connect to my router, the phone have issues to autenticate. My router has only a wpa, and in the android WIFI menu i see: "saved" on the connection.

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.
WARNING: THIS IS ILLEGAL IN SOME PLACES.
If you are blocked from the internet at any place like the library, or school, or anywhere else here is the solution to getting unblocked.
First, you MUST be rooted to even attempt to do this. If you aren't rooted use Kingo root or Iroot. If neither work then just PM me and i will help you.
Second, after you are rooted you go to the app store and download the app Mac Changer .
When the app is finished downloaded make sure that you have backed up everything n your device via recovery on a SD CARD (regular storage can be used).
What this app does is change you MAC address and changing your MAC address can mess your device up in a way if done incorrectly.
An issue that some people have are bootloops or bricks etc.
If you follow everything in this guide then you will be fine. Third open the app and Grant SU access then it is pretty straight forward after that put in a new Mac Address
and Save. ONCE YOU RESTART OLD MAC ADDRESS WILL RESTORE
That's it thanks for reading my guide
