[Q] Wi-Fi stopped working

After a week of being a happy Sony Xperia ZR (4.1.2, C5502) owner, my wifi stopped connecting to networks. I can't connect to any network I have tried, but the list of networks is ok. It stopped working suddenly. My previously used networks are all marked as "Saved", but when I try to connect the following happens:
1) Saved (doesn't even change when tapped)
2) Connecting -> Saved
3) Connecting -> Authentication problem -> Saved
After half day without wifi, this is what I have tried to fix it:
1) Restart phone
2) Restart phone, take out battery, SD card and SIM card
3) Restart wi-fi router
4) Connect to another network
5) Forget network -> Type password again
6) Connect another Android device to the same network
7) Connect another non-android device to the same network
8) Sony Companion -> Repair
Nothing fixed the issue, still the same problem.

Any ideas? How to diagnose more, is it HW or SW? I am going to call to support but I know they are just going to guide me through: "Have you tried turning it on and off again?" questions and then recommend sending the phone back to them...

Reset your router settings.. flash your phone using SEUS. If not working after that too.. reinstall once more patiently.. It worked for me

I did factory reset of everything. Still not working. I think the key is why is wpa_supplicant getting: "CTRL-EVENT-ASSOC-REJECT" from the router and why it was working last week (with no changes at all).

I have tried this in another office where there are three wi-fi routers. All three have the same problem: CTRL-EVENT-ASSOC-REJECT. But one of them works sometimes...

Can you try to disable all power saving plans and reboot your phone. See if it fixed. I've fix the wifi keep droping by disable power saving plans

I went to the service centre and it is HW problem. Now waiting for them to replace it. :good:

That is good news.

[Q] Radio (gsm) turned off when 3g is enabled

Hi,
I've been using cyanogenmod in my p880 for a while now and it worked pretty well until last weekend when it started loosing radio (gsm) signal.
After a while I noticed that when I was home, connected to wifi, it didn't occur.
Testing a little bit I found out that the problem was in the 3g. If I set the phone to use only 2g it works, but when I switch to 3g it looses the radio signal after a minute and does not work again until reboot.
The phone gets hot and the battery consumption increases a lot. In the battery status it shows that the "Phone" app's cpu time in "real time", like 100% usage, even with no calls at all..
I'm currently using nightly builds of CM 11, but I flashed the stable CM10 (with factory reset, data wipe) and the problem persisted. Then I flashed the latest nightly again, after another reset/wipe.
To use logcat I turned on the phone using only 2g, started logcat and when switched to 3g. The complete log can be found here:
https://drive.google.com/file/d/0B29xKdkT5wYzZmhleFZlcUhYc28/edit?usp=sharing
It was the first time I saw a logcat file, so I'm not sure, but I found some relevant things:
05-19 17:34:28.263 D/MobileDataStateTracker( 531): default: Broadcast received: android.intent.action.ANY_DATA_STATE apnType=default

05-19 17:34:28.323 D/MobileDataStateTracker( 531): supl: Received state=DISCONNECTED, old=DISCONNECTED, reason=radioTurnedOff
I hope someone can help me so I can use 3g again...
Thanks

check the settings for your apn
try with another kernel
Does this happen with absolutely no apps installed? (i.e fresh install?)

So I am not alone

+1 here
I believe that it all started around 0427 Nightly, not sure, though.
I thought of switching to 2g network only yesterday after reading an old post in CM forums.
Did not have time to pull a logcat, yet, thanks for sharing! Hope somebody will figure out what the problem can be...

My settings are as per wind IT specifications, but I noticed that in CM settings there is much more than specified by Wind, such as apn protocol, apn roaming protocol and bearer, which values are unknown to me. Will investigate on those values.
Tried also with official CM11 stock kernel, with no success.
No, I did not try with no apps installed, I will keep this test as the very last resort. I did not install new apps since when the problem started.

I checked the apn settings and they are ok..
It happened with a fresh install as well, when I fleshed CM10.
I didn't try another kernel yet, but Ottonet did and it did not solve the problem

SignalStrength: Hotfix TD-SCDMA
There could be some interesting news for those like me who are affected by network losses when in 3G.
One of the commits that will be compiled in tomorrow nightly amends misbehaviours in Android/telephony/SignalStrength.java
This is "Take 2".
https://github.com/CyanogenMod/andr...mmit/94186f84815c8f179ebee6b1d07b086fd06af489
The first attempt was made (so far as I was able to reconstruct) on April 28th, see here
https://gitorious.org/cyandreamproj...mmit/cbd9cf1fa383ea588a5a445306534c01f8aa1ca8
I believe I've had 3g issues since the end of april.
Now, I'm not android developer at all, and I would not like to arise too much xpectations or to get overexcited about something that has nothing to do with network losses when in 3g, so I would really appreciate if somebody more skilled than me would provide some comment/explanations.
[EDIT] it turned out that it was *today's nightly*, so, if there is some improvement, it can be enjoyed right away.
Downloading...
[EDIT 05232014] No joy. Whataver it did that fix, it did not solve the network loss issue.

Just confirming, I also installed the last nightly (05-24) and the problem persists.

Does anyone think it could be a hardware problem?

Hi..the problem still persists (I'm on Wind). I've always used Vanir, now I switched to official Cyanogen Nightly...still nothing happens

Hi. I had cellular network problems (no signal) in omni ROM and cm official too. Anyone tryed changing base band? I have v20a EUR ... Anyone tryed different?

I have the same problem as well, it started around 2 - 3 weeks ago, I was on beanstalk 4.4.2, a build from march, if I remember correctly. I had no issues before, but suddenly I lost signal every time on 3G. I tried several Roms with and without the RIL-Patch by Flying_Bear, but nothing helped so far. The only "workaround" is to stay on 2G. I'm starting to get tired of constantly reflashing my phone to try other Roms.
Its strange, that the same error occurred around the same time for so many people. I would like to know if it also happens on stock, or if its a special hardware-revision that fails. My phone version is SWS-Black (Swiss market, but bought in Germany).

It looks like something in the connection behavior got changed. When using earlier nightlies you could observe the phone connecting via HSPA+ (H+) everytime it was possible. But in later builds the phone only connects via HSPA+ if you actively use mobile data and changes back the connection to HSDPA (H) afterwards, thus resulting in constant changes between those network types. I believe this change was included to save battery but it really doesn't if your phone constantly loses connection and you have to reboot. Maybe this change was a global one but as you can see our phone can't handle it. Hopefully demetris can either identify that change and revert it or fix it.

@rob3110 , i understand your frustration, i'm changing ROM too. I also did try EPRJ RIL without success. Now I'm experimenting a RIL from CM 10.2. It seems no Dev is looking into it, it's a pity. I'm trying to analyze error logs but I'm no real Dev... You can post your logs if you like

Right now I'm trying the strange bug-fix JustChris20 posted in the EPJR-RIL-fix thread:
http://forum.xda-developers.com/showpost.php?p=53015495&postcount=105
1. install your rom of your choice.
don't modify anything, no ril, nothing...
2. shutdown your system and remove your battery. Now press the power button for 30 seconds. Wait further one minute. Now insert your battery back and start handy. enjoy your network... ?

(But without flashing a new Rom) So far I haven't lost connection for the last hours, but it is to early to be certain. I'll have to test it for at least some days or weeks to know, if it helped permanently. Maybe it helps others as well.
Just for interest, what carriers are those on with this error, or what countries are they from? Does it only happen in Europe (I'm from Germany)? If so, what happened, did something change with the hsdpa or hsdpa+ networks? Or does this error occur all over the world?

I am having the same troubles and I am also from Germany (carrier: simyo).
I did follow your instructions and will report if it worked or not.
Edit: today I did have another disconnect, so unfortunately this rather easy "fix" didn't work out (at least for me).
Hopefully someone finds another sollution.

Yeah, didn't work for me either. I still get those disconnects on 3G. I will ask my carrier (E-Plus) if there was a recent change to the 3G-network that might have brought us this error, but I don't think they will give me a useful answer...

Nexus 5 (hammerhead) - Tethering broken?

Hi,
Since about 4.4.3 (possibly 4.4.2?) wifi-tethering broke.
logcat says:

D/AFWall ( 3615): isWifiApEnabled is false
This bug is reported on code.google.com but the only suggested solution is deleting /data/misc/wifi and reboot which didn't work for me.
I even chmoded 777 /data/misc/wifi and hostapd.conf but without any success.
I'm running a very recent nightly (a few days old).
Any thoughts?
Thank you.

Suddenly fails to find any network operators

My son's Moto X with unofficial Lineage OS 13 has been working just fine until today, when it suddenly stopped finding any network operators. The SIM card is still recognized, I may enter the pin, but then it says "No service", and when I go to network operators choice, I find that not a single operator is displayed.
I tested the SIM in another phone, it seems to be fine. I also inserted different sim, which I know to work into this phone, but that did not help.
This is what I get from adb logcat, but I can't make sense of it:

Could it be that suddenly the hardware has become faulty? Does anybody have suggestions how to test for the cause?
Thanks very much in advance!!!

Did a factory reset, which did not solve it. Still no network operators found.

Trying to understand the problem. logcat reveals that when it scans for networks, something goes wrong:

Can someone enlighten me, what CSS stands for?

This "Generic failure" sounds spooky to me. As if something about the hardware is broken.

Have you tried restoring to the stock firmware? If not, try the following commands in fastboot mode first:
Code:
fastboot erase modemst1
fastboot erase modemst2
Additionally, in the Phone app, you may dial *#*#INFO#*#* (*#*#4636#*#*) to obtain more information about the device's network.

Yes, but that also did not help, so I returned to LineageOS again.

I am not clear what that does. Seemingly, it erases two partitions. Is their content rebuilt after? Are those two partitions shipped with the custom rom? I did several google searches and each time I found it accompanied by the instruction to flash something else in the next step. So before nuking a partition I certainly would want to know., but so far I have not found an explanation of the partition layout.

I know. There it says it has no cellular network. As the logs I posted indicate, something goes badly wrong while searching for cells.

Tried it now, after a backup, but it did not change the situation. The sim card is recognized, but "no service" remains.

The fastboot commands clear the modem cache, and the cache regenerates on boot up.
Unfortunately, it looks like your issue is hardware-related. Which method did you use to restore to the stock firmware?

Which really would be a first time for me. I never saw the GSM module of a phone suddenly fail. My son insists that nothing had happened..
Yesterday, after reflashing the stock firmware yet again, I shortly got a very weak signal, and then, after I went to manual operator selection, it immediately went away again and stubbornly remained absent since.

TWRP (adb sideload). I am not sure whether the image is flashable via fastboot.

As a last resort, I would suggest locating the full stock firmware for your device and follow the included instructions (if any) to flash it via fastboot, or at the very least, flash the fsg.mbn and NON-HLOS.bin for your device as listed under Modem Firmware in this thread. Instructions for flashing are included in the downloaded archive.

I reflashed them but as a result, the sim card is no longer recognized, rebooted several times.
Update: Reflashed lineageOS and now I got my sim card back, although still not connecting to the network. Reflashed the stock firmware with twrp (not sure how this would be done via fastboot), I got my phone to re-connect to the network for a few seconds, which made me jump up and down in excitement, but then the connection dropped again, before I could even make a phonecall
Update 2 Tried a different sim card, but again, when I try to register automatically, this is what I see:

Wi-fi and BT Failing to Start after Rooting Issues - No solutions worked till date!

Hi All,
Need some help in getting my wifi and bluetooth back to normal. It's over a month now and all my attempts have failed! I would really appreciate some ideas here. Thank you, and sorry for long thread.
Phone info:
Samsung galaxy S6 SM-G920T (T-Mobile), firmware version: NRD90M.G920TUVS6FRC1, stock OS with root and TWRP recovery
Situation:
Bluetooth does not turn ON at all
Wifi takes a long time to turn ON, and only way to turn it ON is from settings (quick access tile does not work)
Wifi does not remember any password
All other functions work correctly, and the phone is now lightning fast after factory reset
Details and Steps Taken:
Rooted my phone a month ago, and started changing config. Took OS and app backup only, but no EFS/other partition backup.
Turned OFF "Allow OEM Unlock" - don't ask why
This (I believe) resulted in WIFI not remembering passwords, so after reviewing potential solutions, I changed "Secure.Storage" value in build.prop to "0"
Took backup of WPA_supplicant.conf and deleted the file
Problem was not resolved, and I had to restart the phone
Restart resulted in FRP lock - to resolve this I re-installed the OS from stock firmware from Sammobile; Yet - no luck on wifi and bluetooth, error still persisted
I reviewed the system log and found tons of errors (listed below). Based on errors, I tried:
Copying libbluetooth_jni.so library file to '/system/lib' and '/system/vendor/lib' folders
Changing 'semGetAllowBluetoothMode' value to "True" - this reduced some errors (refer below)
Validating file / folder permissions for the /efs partition - they seem to be appropriate, but I cannot confirm since there is no reference
I have also tried using SmartSwitch - but it doesn't recognize phone in download mode. It backups the apps, etc. though
Also wiped the system partition once using TWRP, and re-imaged. Yet no luck.
My hunch currently for these errors is:
The /efs permissions became incorrect or partition became corrupt due to some configuration I performed
The system lost its encryption key when the "OEM unlock" was disabled, and thus cannot read any files from the /system and /efs partition (the device was NOT encrypted, but I am thinking /efs is always encrypted by system - correct me if I am wrong)
System log snippets:
Bluetooth Related Log:
Bluetooth GATT service:
Code:
BtGatt.GattService: [GSIM LOG]: gsimLogHandler: null, msg: MESSAGE_LOAD_PREF
Bluetooth Adapter Service:
Code:
BluetoothAdapterService: onProfileServiceStateChanged() serviceName=com.android.bluetooth.gatt.GattService, state=12, Message sending
semGetAllowBluetoothMode:
Resolved this error by updating the value to "True" in build.prop. Was this the right fix, or is it supposed to get value = 2.

DevicePolicyManagerService: semGetAllowBluetoothMode - value retunrs : 2
