[Q] Borked my Wifi

I wanted to enable wifi tethering with my Verizon Galaxy Tab to my Fascinate. Now I cannot get my Tab to see any networks.
I thought I'd made a clean copy of my original wpa_supplicant. BUT I cannot find it - seems to have gotten deleted.
If someone would post me a clean copy of the /system/bin/wpa_supplicant I would greatly appreciate.
Thanks

If the t-mobile one is the same I can share it just unsure if it is
Sent from my GT-P1000 using XDA App

I tried it - didn't really help

As I said, I was trying to get the wpa_supplicant file replaced and Wifi AndroidTether working.
I tried everything. Until I went to data/wifi and copied bcm_supp.conf from my Samsung Fascinate.
Bingo Bongo Bingo!!!

Hi,
So far none of the modifications i've tried worked, so if anyone has any suggestions please let me know.
1) Removed "bcm_supp.conf", so it got recreated - no effect.
2) Took a copy of "wpa_supplicant.conf" and renamed it "bcm_supp.conf" since they may have the same contents - no effect.
3) Modified "wifi.conf" with a different path and the file got recreated there - no effect.
[....
SUPP_CONFIG_TEMPLATE=/system/etc/wifi/wpa_supplicant.conf
SUPP_CONFIG_FILE=/data/wifi/bcm_supp.conf ==> SUPP_CONFIG_FILE=/data/misc/wifi/bcm_supp.conf
...
SUPP_CONF_FILEPATH=/data/misc/wifi/
...]
Rebooted the unit after each experiment and attempted to turn wifi on. It tries to scan and finds absolutely nothing (no AP) even though it used to.
Thanks

when i change my wpa_supplicant file to see adhoc networks i faced the same problem and i figured that it was because of the file security settings chmod it to 766 and it worked. you can try this.

Unable to scan networks

I found a wpa_supplicant.conf in /etc/ and a bcm_supp.conf in /data/misc/wifi (not in (/data/wifi like I read in many forum posts). Which of these files do I need to remove or correct in my Samsung Moment 2.1?

for making it see adhoc networks?

No, for the "unable to scan for wireless networks" problem.

Thanks kromosto. It was permission related after all as file replacement with root explorer solved the issue.

Help with wpa_supplicant and Ad-Hoc Wireless

I am following the instructions as per the below thread to allow my Acer a500 see my Nokia N900 for tethering purposes.
http://forum.xda-developers.com/showthread.php?t=1033314
I have copied the wpa_supplicant file over the one thats already there.
Now when I open the Terminal Emulator to try ADB remount it comes with an error saying device not found.
I have the wifi turned off, I also have Root Explorer, but I found File Manager HD quite handy.
Now after trying the instructions I now dont have wifi - it comes with an error.
I have tried copying the stock wpa_supplicant file across, with no success.
Can someone please help.

to get AD-Hoc working you first need root and either root explorer (paid app but worth the money) or es file explorer (free but you have to enable root privaleges inside the app. its under the settings menu)
1. navigate to system/bin and copy wpa_supplicant
2. past this to your sd card as a backup
3. rename wpa_supplicant to wpa_supplicant.old
4. extract the file from the download and past it into the system/bin folder. (should be wpa_supplicant)
4. Long press on the file once copied
6. select Permissions and set to User: RWE, Group & Others:RE only
This is the easiest way to fix this... make sure in root explorer you set to rw at the top left in order to rename copy or past into this directory..
Good luck

this is the file .
View attachment wpa_supplicant.zip

Thanks for that, your a genius.
Now that my device can see my phone, I cannot see any web pages.
Is there something else I need to do?

That is very odd .. try rebooting the phone and the tablet..
also try on the tablet
go to settings / applications.. go to the web browser.. and clear cache and data..
is only thing i can think of ..
never had a issue other then my cell sometimes get hung on a cell tower and a reboot fixes this.. .
try connecting another wifi device to the phone to determine if its the tablet or phone..

I ended up changing the program I use to tether on my N900 and now works a treat.
Once again, thanks for your help

Thanks erica_renee . Worked right on point !

Thanks

You are Very welcome..
But i do want to point out They are not my instructions..Its been so very long ago i dont remember who to give the credit to.. I think someone from the Zoom Forum..
I just remembers how to do it and do not mind sharing what i have learned with anyone...
So i guess i should say thanks to everyone who is actually a developer or close.. for all the hard work they have done to make my tablet enjoyable to use..

I downloaded es file explorer and enabled root exploring as well as "Mount File System" (which is supposed to make the system writable) and with or without the mount file system, I cannot find the System file nor bin. I have the Samsung Galaxy Tab 8.9 Wifi Only. It's running Honeycomb 3.2. Any suggestions?

Not my credit
This fix is not from me.. I just re posted something that has been around since our tablet was released.. I would say give that person the credit. I am not sure who actually did it .. I think that file originally came from the ZOOM FORUM.
Anyway Just wanted to make sure that was POINTED OUT.I only know from what i have read for my own personal use.
Thanks All ... Erica Renee

Can anyone help me with this?

check you su. update the su root binaries . make sure busybox is installed and updated..
you can check the last two with root checker . a app on the market..
There iss also somewhere in the settings. that show a mount point . .something like /mnt/sdcard.
this should be just a / in there to have access to the system folder. I dont have es file explorer installed as i did not like it.. but i do remember having to change this defalt mount or folder option.. Astro file manager and some others also have this defalt . You can also keep going back and will take you there ..

Even though Titanium Backup says I have BusyBox, another app I tried to install said I did not and needed to install, so I went to the market to install and BusyBox says I need to perform Nand Unlock before installing BusyBox. Can you point me in the direction for doing that. I have the Galaxy Tab 8.9 Wifi Only. I see alot of stuff out there but not sure if it's right for my tab or if the instructions are universal to android users. How did you do Nand Unlock?

[Q] Problem With Package Installer

I am having a problem with the package installer on my Nexus 7. (Wi-Fi, 32 GB) I think I may have done something to it accidentally while browsing through the system files. I did click to install the installer itself out of curiosity, though, but I don't know if that could have any adverse effects on anything. I cannot install any apps, whether they're from the Play Store or an APK through a file explorer. I get error 406 when I try to download anything from the Play Store. (Except when I tried to update ES File Explorer. That worked fine... Every other app that I've tried will not update/ download.) When I try to install an APK, I get a message like, "There is no program to open this file." I had just rooted my Nexus after having it for nearly a year with the Motochopper root exploit, so the bootloader is still locked. I could still install apps, though, until after my first reboot. Could anybody identify the problem? Any help would be greatly appreciated!

you might have removed packageinstaller.apk thats in the system. you can fix it by getting the correct packageinstaller.apk from the interent and move it to the correct /system/app path and apply CORRECT permissions for it

It's still there. I think installing it with itself out of curiosity is what messed it up. It now shows up in the installed apps menu in Settings.

It doesn't seem that I am able to change permissions. I'm just going to back everything up and either flash a stock rom or another good rom. Thank you very much for your help anyways.

Same problem..
What do you mean about "changing permissions"? If you mean to change the file properties to -rw-r-r- then that didn't worked for me .. pls help!

I hope you did save the file .. when you restart your Phone.. Anyways If you have a Custom recovery ie: Philz or TWRP try to download and flash this file Via recovery.. but if you dont have a custom recovery or the file doesnt work after flashing , I hope someone can help you with this issue mate .

I figured this out ... Go to more networks ...do search for netwoks ...when it finds networks do a select automaticly .. Dont choose your network ..For some reason it selects gsm/umts if you select it yourself
Im rooted using a i9505 rom using an ATT branded GS4 unlocked using tmobile Sim LOL

hi iam nikhil
i have not seen persist.radio.lteon.xml file in rootbrowser in samsung s4 i9500what should i do

After you have rooted the device completely, go to Google Play and install 'ES file explorer'. Open the app, and press the menu key on the device and you will get a panel to your left on the screen. Scroll down and enable Rootexplorer (you will ask to grant permission by the SuperSU app since you have rooted, so give permission). Now use the search function and find the file with this EXACT name 'persist.radio.lteon' and delete it. Please make sure you are deleting this exact file. Don't delete anything else and end up bricking your device. After deleting restart the phone and that's it! You will have the LTE/WCDMA/GSM option in the network mode once you are booted and you will receive 4G signals if you are in an area with LTE coverage.

Get another device. The I9500 does not have LTE, and before you ask, you cannot enable it because the hardware is not present.
@chashmaa: Your advice works only if the device has a LTE radio. The I9500 nikhil has doesn't.

My post for busylittlebee(post 1).

@chashmaa: Why would you reply to a post that's nearly two years old? Besides, based upon the time stamps, it appeared you were replying to @nikhil.73.

Big sorry.

OK sir thank u

FIX FOR MAC 02:00:00:00:00(WiFi and hotspot not turning ON)

Important. Root required.....
Hey everyone,I saw so many posts regarding Android & iOS that the Mac address is changing to 02:00:00:00:00 and WiFi is greyed out. None of the WiFi or hotspot not turning on.I get the same problem in my Condor and I searched a lot for the solution.I go for factory reset, full reset, flashing stock, radio etc.... But nothing helped. Some strange solution was to hit the back of the phone, put it in the freezer etc...I tried many other ways and that worked only was putting a file named
WCNSS_qcom_wlan_factory_nv.bin
In to the folder / persist....... But it worked me for exactly 1 day and the problem still continued.
So I tried a new method which helped me a lot........
Steps
1.Take a back up of folders /persist and/data/misc/WiFi
2.unzip the below attachment and put the file WCNSS_qcom_wlan_factory_nv.bin
To /Persist folder.
3.[important step].use any file manager to give full permission to the file(Use ES file explorer, I used solid explorer that provides more permission, if ES doesn't work use Solid explorer)..
4. Restart the phone
5. Now your WiFi will be back to rock............
If doesn't work try clearing the folder /data/misc/WiFi/wpa supplicant... And /persist....
If any thing goes wrong use back up's......
Don't forget to hit thanks if it worked......and don't blame me if it doesn't worked......

THANK YOU MASTER!
You just saved my life ..... *sighs relief*

Fixed it.
Teamsek, I clean flashed it, that is when the problem triggered, could't go past the welcome screen, tried to look for /persist folder through recovery, no luck. So flashed again with no gapps then i was able to access filemanager, saw the persist folder followed above steps, No luck. Flashing Radio worked.

Was looking for a fix forever until I found your post
Works perfectly

It seems that your method does work , I have the same problem with my LG V10 H961-n and I'm hopeful that I can fix it.
Should I root my phone first?

I also have a condor with the same problem,but I checked in the root directory and in the /persist folder the file " WCNSS_qcom_wlan_factory_nv.bin" is already there, and so is the "bt_nv.bin"...How should I make my WiFi and Bluetooth work ,it has been like this for months , appreciate any advice

i cant see any folder and i can't make folder in my phone how can i fix it?..

Thanx a lot bro, it work for my phone Moto G 2013

Self corrected?
After flashing the last ViperOS rom, my phone got the 02:00:00:00:00:00 physical address. The phone was still connecting to wireless lan but I wanted to correct the wrong address. Something weird happened while I was prepairing the phone to follow the recommended steps for correcting the physical address issue: for managing files, root permissions is needed... so when I flashed SuperSU and restarted the phone, the physical address was corrected... I don't know why, I don't know how...

This may help

Hey, I'm unable to copy into the persist folder. Every time it's showing permission denied. I'm using ES File Explorer with root access. Still it's not happening. I've even tried Solid Explorer but could not find the persist folder from that. Please help. I'm using CM 13.0. Any later version isn't supported on my device.

Thank a Lot
I was about to give up, and this was going to be the last forum I read to solve my problem, and I must thank you because it was the only one that worked and helped me.
