wifi and bluetooth not working at all .. i am using custom ROM (Havoc OS latest version) android 10 but cant enable WiFi Or BT, the problem Suddenly happend to while playing an online game.
i tried to install the stock Rom but the exact same result Happened to me.
i noticed in about phone section that WiFi has no mac address .. so i tried to set a new mac address to my phone.
but i faced a problem .. when i type in terminal "IP link show" *After typing su to get Super-User Permission* ,this should shows me my phone network interface name and then type this command to set new mac “busybox config NETWORK-INTERFACE-NAME hw ether XX:XX:XX:YY:YY:YY”.
but all i get "/system/bin/sh: IP: inaccessible or not found" i think this is the problem but i dont know what to do right now!
Thank y’all for reading this problem although of my bad English writing.

I already tried this but didn't work
pand gave some error "Failed to open control socket: Address family not supported.........."
then I thought this error may be due to lack of bluetooth module.so I compiled "bluetooth.ko" and loaded.
then the error disappeared but the thing didn't worked..
I think my bluetooth device is not detected by the module because '/sys/class/bluetooth' directory was empty
So still now i am seeking for a solution....

Well it actually is not impossible. I already had it working.
But your phone shouldn't have any issues with BLUETOOTH PAN profile. If having any issues maybe don't expect this to work. And it need not have mobile internet for both phone or PC. Its just phone-to-pc direct connection, no need for internet access point. Lets think there is no mobile internet enabled for the below HOW-to.
Ok here u go. Pair your phone and PC. Initiate BT PAN connection from PC to phone (right click on bluetooth device and select connect-via-access-point). This creates a local connection. Now u need to know local IP address on phone side. Install terminal emulator application and issue the command "netcfg" which lists all connections active. Note the IP address of the connection bnep0 (say ww.xx.yy.zz)
Now open your PC Command prompt and type the command
adb connect ww.xx.yy.zz:5555
it says connected. Enjoy.
Same goes for wireless connection through LOCAL WIFI (WLAN) without internet access point.
Lets think mobile internet is off.
Turn on the portable Wifi Hotspot on the android device and make ur PC to connect to that hotspot. Note down the local ip address of the connection. Then open pc command prompt and type same command as above
adb connect ww.xx.yy.zz:5555
connected . enjoy.
IMPORTANT: First of all u need to enable ADB OVER NETWORK option in phone. This option is present in latest roms like cm7.2 or cm9 or ics roms. If this option is not available u need to find terminal alternatives for this.
Noob here.
Is there any detail guide to do this ???

[Q] Help ? Xperia ARC+DarkKernel+LX : Wifi almost working, only sees the gateway

Hi,
This is my first post, on this great forum, so I'm posting as a "noob"...
So my problem :
- I installed the LegacyXperia 20130908 CM10.1 release. It was working almost OK
- But because of the high wifi drain, I gave the lated DarkKernel a try (http://forum.xda-developers.com/showthread.php?t=2451839)
It seems to perform very good BUT I just noticed something really weird : I have access to the internet through my wifi LAN, I can ping my gateway BUT nothing else works on the local LAN :
ping fails :
[email protected]:/ $ ping -c 1 192.168.1.13
PING 192.168.1.13 (192.168.1.13) 56(84) bytes of data.
From 192.168.1.10 icmp_seq=1 Destination Host Unreachable
The arp table seems incomplete :
1|[email protected]:/ $ arp -a
d810.home (192.168.1.13) at <incomplete> on wlan0
livebox.home (192.168.1.1) at 00:1f:95:26:25:4d [ether] on wlan0
The routes seem ok, the ip neighbours are not :
[email protected]:/ $ ip route show
default via 192.168.1.1 dev wlan0
192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.10
192.168.1.1 dev wlan0 scope link
[email protected]:/ $ ip neighbor show
192.168.1.13 dev wlan0 FAILED
192.168.1.1 dev wlan0 lladdr 00:1f:95:26:25:4d STALE
AH, on more weird thing, the kernel arp table has lots of zeroes for the unreachable devices MAC adresses (yes, I have 192.168.1.13 and 1.15 are up and running) :
[email protected]:/ $ cat /proc/net/arp
IP address HW type Flags HW address Mask Device
192.168.1.1 0x1 0x2 00:1f:95:26:25:4d * wlan0
192.168.1.15 0x1 0x0 00:00:00:00:00:00 * wlan0
And I can't seem to be able to communicate with the local LAN only with the android phone...
I have static IPs in my DSL router, I can't set the arp tables manually.
I *think* this was all working with the default ROM kernel, but before I attempt to revert back to that kernel to check (I backed up the modules, but yet another noob thing, I'm not sure putting back the tar into /lib/modules will be enough...) :
==> this is my noob question : anybody knows how I can report that to the dev, and how I can get help ?
Since it's my first post (only 9 remaining now !), I can't post in dev section...
Thanks && regards
Did you flash the DarkModules?
Hi,
Yes i did flash them in cwm...

Hi,
Thanks for the reminder.
But actually, by dev, i meant the kernel dev : the issue i see is not a force close or things like that,
and it appeared after i flashed this new kernel which seems better for the battery.
I think this is a kernel/wifi modules issue, not a rom one.
Or a noob error, but then i hope some of you can help me understand my error
As i said, wifi is somehow working since i'm replying just now using it...
It's just that apart from the dhcp/gateway, my device seems unable to learn any mac address with this kernel.
I haven't tried a tcpdump for now, and i wanted to test ipv6 but my 'great' dsl/wifi box does not support v6 - yes, that still exists...
Regards

He is also developing the kernel together with his team, which is given within the .zip file.
Ahh... txs.
OK, now I don't understand anymore anything...
I did :
- remount rw /system/
- cleanup and then restore the /system/lib/modules backup I had done - using tar
- reflash the ROM kernel (200130908)
And... still no ping on the wLAN, but I can ping google and the GW. ??
The arp table still shows me incomplete records.
Still I'm 100% sure I could connect before : I did use connectbot to ssh onto my computer and setup new ssh keys.
I don't know what else I can try exept reboot the dsl box (which is the wifi router)... or delete the recorded stuff in that dsl box and that reference my arc s.
Or reflash all, but I always manage loosing stuff when I reflash (which I avoïd doing then), even with titanium backup
That's all really weird...
Side question : is there *always* a captcha verification on every post ?
Cheers

Which DNS server are you using? Did you change anything else by WiFi?
The captcha is only for limited amount of posts, then it will disappear.
I did not change any dns setting, but i saw local names in the terminal, so i must be using my dhcp/box dns.
You remind me i unchecked the wifi optomizations with the new kernel: i read this was causing arp issues on nexus devices...
Lets try to re-enable that... appart from this, i changed nothing after i flashed this kernel.
Except I tried 1.8ghz (it worked well), but this disappeared sincei restored the official rom krtnel
Thats really all i changed since i tried the new kernel yesterday evening
Can you believe this...
- Restoring the wifi optimisations did not help
- rebooting the DSL box helped. For 5 minutes.
I was able to ping a computer on the network, but not to go to the dsl box webserver. and I lost internet.
- subsequent dsl box reboots did not solve anything : no internet, no webserver, no connexion even on the wired PCs , powerd them on or off, nothing.
- *unplugging* everything + dsl box reboot => did restore internet+wifi on the arc
- replugging the PCs did not break
- and I can now see/ping the LAN with the arc s
Only remains, now, the dlink switch I have downtstairs that is the only stuff that remained plugged all time (theres a device on it, but it's off)..... It must have switched to a "netkill" state somehow. Funny, isn't it ?
let's now start wireshark, reinstall the new kernel, and see if there is any difference... and lastly reboot/replug the dlink switch
the come back for the (arp) ping of death ?
Regards
Last experiments:
- fired wireshark, to capture any network suspicious paquets
- reflashed the new kernel+modules
- retried ping / local LAN
Still working.
I rebooted my last network device (dlink switch), repluggued it : everything is still working.
conclusion : I don't understand :laugh:
Cheers

[Q] I9195 - Unable to connect to WIFI network (Authentication error occurred);

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!

Nexus 7 2013 WiFi - WiFi won't turn on after Marshmallow upgrade - bad Mac Address

Just sideloaded the Mashmallow update from 5.1.1 to 6.0 (downloaded from Google) and the update seemed to go normally - most things work as normal. But the WiFi wouldn't turn on, and it's mac address reports as 02:00:00:00:00:00. That address I know was an issue in the M Preview as a fake address.
I didn't want to hard reset it but in the end relented and loaded a clean new version of 6.0 from Google. When it restarts the second thing it wants to do, after selecting a language, is start the WiFi so it can log on. Of course WiFI won't start, and I can't "skip" so it's stuck. I tried Bad_Boyz fromXDA, and then going back to 5.1.1, and now forward again to 6.0 - same result. I suspect the WiFi mac address has been cleared. I found a little help that if I shell into the tablet, and write the mac address into /persist/wifi/.macaddr I might move forward. I know how to do this, but I can't shell in with adb. I can talk over USB, and run fastboot. When I connect via USB the Nexus mounts (sort of - the storage folder isn't shown when the tablet is at the "Select WiFi network" stage of setup)
When I run "adb devices" - I can't see any, even though I can "fastboot reboot recovery" and the like. I'm sure bluetooth (mac address) is broken too, but I"ll fix that later.
Does anyone have any idea how I can encourage adb to talk, so that I can "adb shell"?
Safe Mode
Just so you know - I started it in safe mode, which I have done before, but anyway - and the WiFi works. Also, USB debugging is presumably switched to off on a hard reset, and I couldn't log in to enable it without working WiFi. Suddenly my mac address is back. Don't really know if safe mode is the answer but it's worth trying...
To get into Safe Mode - long press on the "Power Off" question when you turn it off - it reboots in safe mode.

(Need "more" help) WIfi mac address still stuck to 02:00:00:00:00))

Hi,
I have read almost everything that this forum gave me and some solution from the rest of the internet and STILL my wifi mac address is still stcuk at 02:00:00:00:00:00
Wifi won't turn on and it won't display available wifi
I can't remember exactly what caused it but i'll try to share my recollection
I vaguely remember that i was able to connect to the wifi before trying to fix it. Can't recall what really happened
I fixed the random rebooting nexus 5x by using unblod fix
I think i tried rooting it and succeeded with a twrp recovery
I vaguely remember flashing a zip custom rom with wrong version and brought it into a soft brick. Cant find the file anymore.
I reflashed it with flash all batch file from stock firmware
the phone is bootlooping
Fixed it again using unblod exe using the stock firmware's boot.img
Wifi wont turn on
mac address is 02:00:00:00:00:00
Tried on android 6.0, 7.0, 7.1.2, 8.0 and 8.1.0
Other solutions tried:
Nil Mac app. Seems to work app wise but mac is still stuck at 02:00:00:00:00:00 on settings. Wifi wont turn on
Manually edited, placed *.bin file in /persist, and /etc/firmware/wlan/qca_cld/
WIfi mac changer apps from appstore (they dont work)
Some root apps that mess with the phone's setting (cant find anything that seems to deal with wifi mac address)
p.s.
I also tried bricking the phone using TWRP wipe and checking all the wipe locations to eliminate remnants from previous mods
I cant seem to do anything. Still stuck at 02:00:00:00:00:00
Any more suggestions on where to look?
Or is android not getting the real mac address and revert to 02:00:00:00:00:00 and wont let wifi turn on during flash all script?
Thanks in advance.
Recent Android hides the MAC address to prevent tracking. 02:xx:xx:xx:xx:xx means a site-local MAC address.
Try using "ip link" and looking for the wlan0 entry. eg.
Code:
22: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 3000
link/ether 2c:59:8a:xx:xx:xx brd ff:ff:ff:ff:ff:ff

HI,
thanks for the reply. I already did that and i got a mac address that is not 02:00:00...
then i tried to change it using if config just to see if it changes using the command.
I got an error saying wlan0 not found (not exact words)
Is there a different MAC address in Settings -> System -> About phone -> Status ?

Did this ever get fixed? I'm facing the same issue. However, the steps I did was trying to spoof a MacAddress using Busybox and a terminal emulator.
Just using that would not allow me to connect to wifi, but wifi was turned on. Then I read to change the wlan.bin file in the persists folder.
After I changed that file and did a reboot wifi would not turn on.
I tried:
1. factory reset
2.Changing the wlan.bin back to what it was
3.Sideload android 8.0
4.Flash OEM back to factory
Nothing seems to work. Settings->about->status MacAddress says "unavailable", but
wifi -> preferences -> advance shows MacAddress 02:00:00:00:00:00
Any help would be great,

Try AMC, its the only MAC Address Changer app I could find that worked on my 5x. That was without a screwed up MAC address to begin with, but It might work for you.
I downloaded it from the play store, but now its not there. Here's the apk from my phone:
https://sqerk.com/pythonlimited.amc.apk
Looks like AMC was forked from nMAC :

Thanks, but I figured it out. I was trying to flash with the same version 8.0...and for whatever reason that did not work, so I tried a costume ROM and it brought back my MAC address, so then I flash again to android 8.1 and my MAC address problems are fixed. Not sure why flashing with the same version did not fix it.
Thanks,

What Custom ROM did you use friend? I have the same exact issue with my Nexus 5. Maybe finding your previously installed Custom ROM, I can fix the issue too. I saw a lot of threads says that installing Custom ROMs or downgrading then upgrading OS using OTA updates given from their Android System fixed the issue. MAC address is important and controls everything that has to do with wireless connections in your device. Maybe this can help be fix my issue too. I am almost convinced to buy a brand new smartphone. It's almost my limit here... If this doesn't bother you, please, can you tell me what is the ROM you used?
