WiFi issues Unable to turn on/unable to scan for networks

Hello, I'm having an issue, I'm rooted with the nand unlock method. I was on flipz .1d but have now moved to .2. I've had this issue a number of times now specificly the "unable to turn on" which seems to be caused by the owner of the /data/misc/wifi/wpa_supplicant.conf file changing to root. but I am not sure what causes the unable to scan for networks to happen.
Some of the things I have done that seem to be a part of the cause: I ran flipz vanilla lock screen fix and I team douche menu unlock, both seem to make changes to /system/framework/
anyone that might know where to look to fix the scan issue? I've searched the forum and have seen a few people have the problem but no solutions yet.

Was having the same problem (came across your post from a Google search).
I got a hint from code.google.com (can't post the link). I renamed the /data/misc/wifi/wpa_supplicant.conf to /data/misc/wifi/wpa_supplicant.bak (rather than delete it), rebooted and all is well.
Seems you can just delete the file, and it'll be respawned on a reboot.

I am having this problem, but on a vibrant that has not been rooted yet.
I cant seem to find the wpa_supplicant.conf, I have tried browsing for it using the built in file manager and using ASTRO, but the data directory is always empty.
Is there a way to fix this without rooting the phone?

if your phone has not been rooted then that means your phone is f**ked up and might need to be exchanged. but this is the evo forum not vibrant. the only way to mess with system files is to be rooted

Appreciate info*, worked in a heartbeat, saved from reloading everything from scratch, which was my way out last time. Witstech A81E Froyo 2.2
*renamed the /data/misc/wifi/wpa_supplicant.conf to /data/misc/wifi/wpa_supplicant.bak

Good eye there mate!!!!

It just recreates the file when your phone gets rebooted. My Thunderbolt is having the EXACT same issue. Ive tried renaming this and deleting as well and still no luck. Im now kicking over any rocks that I can find to get my wifi working.

I have exactly the same problem.
With Root Explorer deleted the file 'wpa_supplicant.conf' but no changes.
WiFi starts up and closes down again with the famous line: "unable to scan for networks"
anyone?

I had the same problem. I installed the software from the sony erikcon website to my computer, and then followed the process for updating the phone software. That did not work, since I had the latest software already. So then, I tried to REPAIR my phone software, and after that was done, my phone was functional again, and the wifi works without any problems.
Requirements:
* A PC connected to the Internet (preferably broadband)
* USB phone-to-PC connection. Please see the accessories compatibility list for your phone.
1. Run the software on the computer after it is installed.
2. Follow the procedure for UPDATE or REPAIR (if you already have the latest version).

Wife Tether (How to make it work)

Hi guys, question, I can't get wifi tether to work on my netbook.
It's there anything special I have to do to the netbook in order for it to allow the connection because it says connected but the internet doesn't work, thanks in advance.

From the Subject Line, I though your were trying to tether your WIFE.... sadly, that is not something possible in most cases.

i had this problem, it was because i swapped out sd cards and didnt have the bin file on the new sd card..just Delete and reinstall the program, and a newly generated bin file will be placed on the card..should work!

Go to Menu -> Show Log. If you don't see something similar to
Loading bcm4329.ko module (fw_bcm4329.bin from /sdcard/android.tether)...

then you need to follow the instructions at code.google.com/p/android-wifi-tether/wiki/Setup_HTC_Desire_Incredible

How to connect to a Mobile HotSpot. 2ways.

Hi guys,
Since the mobile hot spot is an adhoc networks, so tablet cannot recognise it
directly.
So I found a instruction which is called can solve this problem.
We simply replace the original wpa_supplicant with the new one.
And put it in /System/Bin/.
I did the root and copy, but it still cannot find the adhoc hotspot for me.
So anyone have any idea?
Solution 1: solving it with the magic "wpa_supplicant"
Solution 2: changing the configuration of hotspot in my mobile to a normal wifi.
I'm waiting for anyone who can solve this.
Cheers
Winston

Hmm. I have a mytouch 4G and the A500 connects to the hotspot easily. No mods, rooting etc. needing.
Is this in relation to phones that are using less than carrier proposed methods for enabling hotspots?

Hi Neo,
According to what I have had known so far, it seems that google blocks this function,
so someone modified the wap_supplicant to enable the hotspot functionality.

Solution 2 depends on your specific phone and its implementation. My Droid for instance doesn't support infrastructure hotspot (outbound), so I had to use the "magic wpa_supplicant" approach. Other phones may support infrastructure mode, either directly or through a 3rd-party wifi tether app.
In terms of solution 1 - if you get the wpa_supplicant (apparently a new version has been posted for those of us w/ 3.1 update) you also need to reset the permissions on the file to match that on the original file (which I know you backed up, right? ); easiest way would be through Root Explorer and set Read: (Owner/Group/Others), Write (Owner only) and Execute (Owner/Group). I'm too lazy to remember what the Terminal Emulator chmod command would be
As a reminder to all who do choose to replace wpa_supplicant, keep a copy of the original file, you never know when Acer's going to require a specific original file for any future updates (wpa_supp wasn't needed for the 3.0.1 update but was for 3.1)

Yes I would say do not delete or move the old file just rename by adding old to end of file name. Its how I done it renamed did the update changed back. And now all is well again.I used the same replacement file from before. No need for a new. Version

Hi Vereyn,
Thanks a lot.
Could you please provide the link to download?
Frankly, I have tried all wpa_supplicant in this forume.
None of them works for me.
My version is Android 3.0.1
Acer ICONIA A5011, rather than A500.
Cheers

Soo... Which rock have you been hiding under exactly? This is pretty old news, and there are already a few threads detailing exactly what you need to do... Hell, there's one on the first page of this forum section!

Dear Floating,
Could you please send the link to me? or at least give me the title of that article which
you are talking about?
Because it disappeared again now >_<;

Again,
yes there are many ad hoc articles, but none of them work for me....

Pre-define System Settings Before Flashing and/or integrate DroidWall

Hi, i want to know if it is possible to pre-define settings like mobile data (off) or account sync (off) or any other before flashing? Is there a file which i could edit?
Oor if this isn't possible, whats about to integrate DroidWall into system? Status should be enabled(requires root permission). Rules aren't important since DW blocks every activity from the start.
The thing is, every time i flash a ROM and type in my PIN, android activates mobile data automaticly and sends some bytes. I simply want to stop android from doing this.
Actually i am using the latest ICS build.
I appreciate any suggestions.

Are you wanting to completely turn off mobile data?

For example I want to prevent android activating mobile data by typing in my pin after fresh rom install, if you know what i mean. So ofc i should be still able to switch it on if needed.
I just want to set a few system settings before flashing. Like Accounts & Sync off and GPS Satellites off.
Xylograph told me he hasnt seen any option for it yet, but if there is any it might could be stored in /data/data or /data/misc
Sent from my HTC HD2

i did a little research and found following:
for predefining Systemsettings:
/data/data/com.android.providers.settings/databases
there is a settings.db which changes in realtime if i change any systemsettings like bluetooth or wifi or gps. if you open it there are some sub entries. the systemsettings are in settings.db/secure and /system
i ll try to set up my rom now like i want, copy then the file and paste it in a romfile with the same dir location. lets see if this works after flashing. the settings.db file can also be edited.
for DroidWall integration:
also for DroidWall i will create folder for
/data/app/com.googlecode.droidwall.free-1.apk
/data/dalvik-cache/[email protected]@[email protected]
/data/data/com.googlecode.droidwall.free/and all files/folders in it
/data/user/0/com.googlecode.droidwall.free/and all files/folders in it
the only problem i think i will have is the root persmission per superuser. i need a config file for superuser but i havent found any.
i hope the dalvik-cache file will help
[email protected]@[email protected]
EDIT:
Doesnt work. None of the two.
Android just ignores the settings.db after first start and therefore all predefined settings like GPS and so on.
I am thinking about to set the permission for settings.db readonlny, before flashing.
And DroidWall have no Rootpermission. And superuser doesnt ask me for root if i restart DroidWall.
I think to get DW working i need to predefine Superuser. But i dont know how.

[Q] PERMANENTLY changing MAC address (Samsung Galaxy S5 G-900H)

Hi,
First off i want to state that i have some knowledge of the legal issues concerning changing of MAC addresses and the sole reason that i want to do this is because privacy is a big issue for me and i have a right to enjoy my right. Therefore, any posts or argument concerning such are requested to be posted elsewhere where the topic expressly states so.
Also, please treat me like a newbie when it comes to developing and programming of any kind. I have a very shallow understanding of kernel and the likes.
I am using a rooted S5 G-900H(Exynos with BCM 4534 chip)
Running on 4.4.2 Kitkat stock ROM and Kernel
So without further ado, here is what i have found so far
The MAC address is reflected in a hidden file called .mac.info in the /efs/wifi/ folder. However, editing the file does not change the actual MAC address in anyway. A phone reboot or even turning the wifi on/off will just change it back to the original.
I dumped partitions from /dev/block/ on to my SD card and copied it to my laptop. I searched through the files and found the MAC address in the efs.img partition.My wifi was turned off and the plane was in airplane mode. I modified it and flashed it back using the dd command from terminal emulator on my phone(this can also be done through adb shell but im guessing if you know what that is then you obviously know how to do it).
I rebooted the phone and everything seemed fine. The Wifi MAC address in the status screen in settings displayed my edited address. The .mac.info file also displayed the same. The problem is that it reverted back to the original as soon as i turned on the wifi. The MAC address values in the .mac.info file, status screen and the efs partition from the /dev/block/, all changed back to the original.
I have read that for most phones the important information unique to that particular phone(like IMEI, wifi/BT MAC address, unlock codes and so on) is stored in the NV_DATA.bin file, but everything is encrypted. Also there are only guides as to searching unlock codes and such, so i tried to search for hash blocks randomly using Hex Editor but there was nothing of the sort and the only hash block i can recognize is the one with AES-Encryption as shown from another forum on this site.Maybe it is another type of encryption, but that was another dead end for me.
Then i tried to search and edit various files and kernels as such, but there are no kernels that directly offer this customization. Tried to edit init.tuna.rc but there was no such file in the root directory. Searched init.goldfish.rc and init.wifi.rc and found nothing, but i did see init.svc.macloader mentioned and since i didnt want to mess with programs in the /system/bin/file i left it as is.
Also tried to search through PARAM partition using Hex Editor but nothing was there. Did the same for RADIO and BOOT but i dont think i did find anything major there.
tried to edit /sys/class/net/wlan0/address but it didnt let me, even though i was mounted as r/w. Flashing through dd command on terminal also resulted in permission denied. I was only able to view or dump it. I thought that may have been the source, but modifying the MAC address through the busybox if config command was reflected on the file. which obviously means that its not.
Looked through the dmesg (kernel) log and found a few interesting things but i dont know how to interpret them and what to do with it either. Ill post it later.
There is no NVRAM.txt the only ones in place of it i have are nvram_mfg.txt, nvram_mfg.txt_wisol, nvram_mfg.txt_semco3rd, nvram_net.txt, nvram_net.txt_semco3rd, nvram_net.txt_wisol.
I did do a bit more searching and editing, but i dont recall them right now.
Now, After all that what i think is this.
There is a source for the original MAC address somewhere either hardcoded in the Broadcom chip or somewhere in the partitions under a layer of encyrption.
The Original MAC address is only accessed when the wifi is turned on and not on reboot. This means it is not in any file, program or script that activates on boot, so only scripts and files accessed and imported during the turning on of wifi
must have it. Also while wifi is on and running, busybox ifconfig command changes the MAC address succesfully albeit temporarily, although the change is not seen on the status screen and but it does on the .mac.info file.
Any help from anyone, especially from developers with knowledge of Android kitkat ROm and kernels would be very much appreciated.

As you said, ifconfig changes it, there are several apps that do it for you as well, chainfire also released a mac randomizer app. You also noted it's hardwired in, so i would just have a startup script that changes it if i were you, there night be a better way to do it though.

Yes, I have been using pry-fi as an option but the thing is that when i'm watching videos or downloading large sized files from playstore or other file hosting sites, it starts to turn my wifi on/off several times before becoming stable and logging in to the AP again. I have tried macchanger also and both misbehave after an interval of time. Thats why im trying to search for a more cleaner way to do it.
Running an init script would be nice but i have no idea how to do that. But there should be a script that only runs when turning on the wifi right? Would you know where this file was located and how to modify it? and if so please tell me.

You can just use init.d to make the script, shell scripting isnt very hard and i won't give you a tutorial here. Also as noted many places when researchng changing a mac on android, you can't connect to secured APs, or it won't be easy at least. As i said before, there may be a better way to do this, but i do not know it.
Sent from my Tw5ted SM-G900A using Tapatalk

Ok, thanks a lot. Running a script might just be cleaner than anything else I have right now. I'll still be on the lookout for other ways though. Call me hard to please.
Btw, I think the reason most custom MAC addresses(if they do get changed) are too different than the ones registered on the chip. I've found that changing only the 2nd digit out of the 12 in the address, to an even hexadecimal number like 2 or A, works for me on my pc.
Also you need to forget the networks on your pc or android as soon as you change it. Doesnt matter if you have the password or not, it doesnt connect. Must be something to do with the saved info about the ap on the phone that messes it up.

I know on for example ddwrr and even some official router firmwares they allow you to spoof your mac, may be worth looking into how they do it, but i have a suspicion it might be done with a script.

Hard Wired?
I have been messing with 2 Alcatel Ideal 4060a, (because I bricked the first one i had).
After bricking the first 4060a I had, (wiping all partitions), I bought a second, (so I could install TWRP on it back it up and restore the backup onto the first).
After Restoring the backup of the second onto the first, all was good until I tried to get them online together.
When one connected it knocked the other offline, because they both share the same MAC address.
This is my problem and I wish the Mac Addresses were hard wired, then i wouldn't have this problem.
This is good news for anyone who wants to know if mac addresses are indeed hard wired. They are not, (at least not in the 4060a).
Hope This Helps.
gscripting

MAC for bt and wifi reside in the EEPROM or NVRAM. And that is not editable.

To put it simply you can't change it. Only spoof it. And if you know it's not legal you probably shouldn't be asking.

Reported Is different from original

More info relative to these 2 phones
I installed an app called Change my Mac.
It Lists:
Original MAC 12:34:56:78:90:ab
Current MAC ff:ee:dd:cc:bb:aa
They Are Different.
I thought the original MAC address it's showing, was the one written in the EEPROM or NVRAM,
but it turns out, after installing Change My MAC on the other phone also, its lists the same Original and Current MAC addresses as the first phone.
The Current MAC address listed is the one reported in settings and my network.
I Use Change My MAC to set the reported MAC to the original every time the phone boots using Tasker on only one of them.
Using Change My MAC, the change lasts til boot.
Just passing it on for those that might be interested.
When I get link privileges, I'll add a screenshot of Change My MAC.
