[Q] P970 WIFI lost connection and does not reconnect - LG Optimus Black

Hi there everybody,
a few days ago my P970 started to go crazy a bit. It suddenly lost Wifi connection and won't reconnect. The Wifi symbol in the status bar looks like it is connecting, but nothing happens. Additionally, under the wifi settings, the on-off switch of the wifi is light grey (greyed out) and does not react anymore on my input.
As I could not find any further information on this topic, I decided to do a factory reset followed by a reflash of the V30B (Europe open; Android 4.0.4) and another factory reset as well as format of the SD-card. After that I did not encounter any problems until I finally wanted to customize my phone again with apps etc.
Last night again I lost the connection to Wifi and just decided to see what will happen. Until now (16 hours later) the Wifi icon is still kind of showing a connection attempt and is flashing non-stop and under settings the wifi-switch is still grey.
Anyone got an idea what could be wrong with my phone? Hardware or Software problem? If I leave Wifi switched off, there is no problem with the phone, but it sucks if one cannot use the wifi...

Well maybe think about, what MODs (like PimpMyROM) and apps you installed. Maybe one of them causes the strange behaviour... If you say it works, till you start to customize it, it probably is a problem with any customization...

Make sure something will trigger Wi-Fi AP. If yes, Wi-Fi will not turn on, and the button is greyed out.
Excuse my bad English.

Does anyone know the significance of greyed out network icons?

I upgraded to R3A last week and so far everything's gone smoothly.
The only thing that's bugging me is that the network icon (H) spends most of its time greyed out (see screenshot). I only ever saw it in that state briefly in previous firmware.
It doesn't seem to affect connection or call quality. It's not indicative of a bad signal, as it'll still go back to 2.5G when 3G is lacking. The resulting G will usually be grey as well.
Presumably it means something's less than optimal, but I can't find any info about it anywhere.
Clues anybody?
Are you sure you are able to connect to a data connection, for web browsing etc? Because the last time this happened to me, i was not able to connect, and had to do a hard reset to get it fixed.

Data connection works fine. There appears to be no issue with functionality of anything.
The set of "custom" status icons (colored ones) doesn't contain icon for HSDPA (or something like this, dataconnection available in you location) so it is shown as standard icon (only black&white). I bet if you have only EDGE or GPRS available, there will be the same icon as the others are.
it should mean that data connection is unavailable at the moment (because it can get back in a later time) or something is wrong with your data connection (that is why we have sometimes to reset the phone to make it work back).
Guys,
I have a Xperia for almost one month, and last night it suddenly stopped to be connected with the network. I tried to connect manually, and it worked, but the calls still couldn't be done! One hour later, the same situation started again and my phone can not connect to the network.
I don't know what to do anymore, I have already hard reset the phone, and nothing happened!!
Help me!

I get exactly the same thing, running Jacks latest lite-ROM, based on the R3A. Connection icons are greyed out, but I still have an excellent data connection.
What's more is that after a fairly long call, the phone usually looks like it's in flight mode. However, if I try calling myself from my second phone it works just fine, and I can recieve sms-es. But, I cannot send texts or call out, since the phone thinks it's cell-module is turned off. This always corrects itself after a soft reset, and usually passes by itself after about ten minutes. But the connection icons stay greyed out.
If I try to turn the phone-module back on, nothing happens.
Weird, innit?

[Q] Fixing Wi-fi without reformatting?

Hey, in the last few weeks I've run into a very annoying bug on my phone. Wi-fi turns itself off after about 2 minutes. It doesn't actually "turn itself off" in the phone - and by that I mean that the wifi icon is still there, and I can see the signal strength, but the internet won't work.
In order to fix it, I have to turn the wifi off and then on again.
I've tried using the Wifi Fixer application, but it doesn't help. It can't seem to detect when I lose my internet connection.
I've also troubleshooted it, checking that it occurs on different routers/types of networks.
I'm sure it's a problem with my phone, but I dont really want to reformat my phone until Froyo comes (since I don't want to have to install all my apps twice).
Is there any solution to this? ;z
I'm on stock rom, JF3, with OCLF.
I have the same problem with my phone. My Wi-Fi at home works just fine, but when I go to my brother's house, I seem to occasionally lose internet connection even though it shows that it's still connected to the Wi-Fi. I have stock Bell ROM with OCLF by RyanZA. Oh, and to fix it I simply turn Wi-Fi off, and then on, and it starts working again.
Bump :x
Anyone have a solution?

[Q]WIFI not working everytime.

Hi,
I'm a proud O2X user.
Only issue I'm having right now is that WIFI won't start all the time.
Sometimes I enable WIFI and it gives me error.
Sometimes I enable WIFI and it directly works.
Most of the times when it ain't working, I soft reset and WIFI is powering on again.
I had this same issue on my DHD. That was caused by the kernell. So I think it's the same with my O2X. I'ma wait till 2.3.x cause I don't use WIFI that much. And If that doesn't fix the problem, I'ma make use of the VIP service.
Other people expierincing this issue.... ??
After I installed Juice defender I think it got a little more diffecult to connect. One time I experienced that my accesspoint in the list had status "Deactivated".

Mine is still stock not rooted....
And when WIFI does power on, it does connect to my accesspoint.
The funny thing is even trying to enable WIFI with hiddemenu doesn't work then aswell....
Got my O2X two days ago, and Wi-Fi reconnection after sleep mode simply doesn't work. It times out waiting for an IP address from the DNS service, disconnects, connects, waits for address, and fails again. Turning Wi-Fi off in Wi-Fi settings, and then turn it on again, solves the problem. Peculiar and annoying.

Same problem here
I called LG yesterday.
The 2.3 will be a big update.
Many thing should be fixed.
He noted:
E-mail client will be fixed.
Some lag in the UI would be fixed.
WIFI should be fixed.
Better powermanagement.
So hope these world will be true.
Or else I'ma trade it for a HTC HD7
Got the same problem, WIFI works sometimes and suddenly it doesn't.
Sent from my LG-P990 using XDA Premium App
This can be router/access point related. Using WPA2 Personal encryption causes my O2X to lose WIFI connection after a short while. Therefore, for those of you with problems, try disabling WIFI encryption (only for testing) or try some other encryption method.
If the phone wont connect to a open/non encrypted router or access point, then the problem lies with the phone (most likely but not for sure).
Try it out!

I got the "Deactivated" too. I got that when I had the phone Wifi sleep policy set to "When screen turns off". When I changed to "Never" it was stable. I have later changed to "Never when plugged in" and that has been stable too.
I will test reverting back to "When screen turns off" this weekend and see if the problem returns.

My WIFI won't start then. After Reboot it will work couple of times. But then again it gives ERROR while start WIFI.
I have had this happen to me the last few days, despite wifi working perfectly the entire of the first week I owned the phone.
I have seen both problems mentioned here:
Won't get past "obtaining IP address"
Switching it on or off says "error"
Also, in the case where it would error, I also noticed a significant slowdown. Plugging the phone and using ADB to read "top" gave me:
Code:
PID CPU% S #THR VSS RSS PCY UID Name
1284 49% R 1 0K 0K unk root dhd_dpc
19960 1% R 1 912K 428K fg root top
Which must be a rare issue as I could only find a reference to dhd_dpc messing up here, for a SGS owner who never got an answer.
Rebooting the phone always fixes these issues. Although sometimes going into airplane mode and out again will solve the "obtaining IP address" issue.
I only have the •Switching it on or off says "error" issue.
I figured out enabling disabling wifi with the LG Control buttons (in the notification bar) fixed this issue.
Now it is always working and not giving me error.
Back it the day with settings or the power management icons enabling wifi 9/10 times gave me error.

Did he mention when we could expect the update?
Btw, you should shut off the wifi-sleep in advanced settings, and the problem is solved. =)
I am a bit concerned..
My phone is connected fine to Wifi at home, and apparently this weekend I have used 91mb of network data!! I did not go out so my phone should have stayed connected to Wifi at all times. But when I wake it from sleep (only woke it when email or text notification came in) When the screen lock pops up there is the 3G/H icon that’s stays until I unlock the pattern – then the Wifi icon pops up….
Should it not stay connected to Wifi even in sleep, as how is it recovering emails and such??
I am eating up my 500mb allowance very quick even when on wifi!!!
I have had no problems with home wireless as my pc (on wireless) has over 500hrs uptime connected.

Don't worry ignore my prev 2 posts. Found the option. the "never" setting I would have through should have been dafault!

LG Optimus 2X P990 - Service Problem

Hello,
Since a couple of weeks I've been having some issues with my beloved phone: the LG Optimus 2X Speed (P990) running the latest and greatest Cyanogenmod 7. And I was hoping that you could help me with that.
The Problem
My phone, and my previous phones have always had great service reception. I would never find my phone with two bars or less, unless it was brain-dead out of juice. I've always had the same provider (T-Mobile NL) and I've never experienced any problems with them.
However, in the last couple of weeks my phone can't find my network more often and often. I'd check my phone to see why I haven't gotten text-ed in the last minute or so, and it would be offline. Zero bars and status "No Service". At the beginning, I could put Airplane mode on, and then off again and it would reconnect. But since a couple of days that won't work either. I can put the telephone into airplane modus, but it gets stuck in it.
The button remains gray saying "Disabling Connections". If you go back, and into the Connection settings again the button can be pressed but indefinitely keeps the phone in airplane mode. The only way to enable connections again is to completely restart the phone. And as of lately I find myself having to reboot the device about 1-4 times a day.
Could you help me with this?

Obviously CM7 went a little crazy! I don`t think it`s hardvare problem and the most safe and secure thing u can do is to go back to stock rom and root and reflash CM7 again!!! Android is weird system and many weird things happen to many people. If u have few hours to spare u should begin there and see what happens. If that doesn`t solve your problem than u can start thinking about hardware failure (maybe SIM card, maybe phone antena). But i`m allmost positive it`s software isue. :good:
Disable the automatic date and time (network-provided one). See if that helps.
That was preventing my P990 from getting network at all after a cold boot.
Hi,
I have exactly the same problem. Disabling network-provided time helped (i.e. the phone connects to the network and data connection is up), but I was wondering if this is a bug and if there's a thread or a resource discussing this issue? Btw, the phone has been having some minor connectivity issues in CM 7.1 as well, but otherwise CM7 is useable.
Phone: LG-P990 (Optimus 2X), "Made in Korea" under the battery, does that mean for sure it's the SU660 flavour?
Carrier: Fido (Rogers Wireless), Canada
ROM: CM 10.1-20130722-UNOFFICIAL-p990 (tonyp build version 5) (Wiped and flashed on 2013.08.27)
Kernel: 2.6.39.4-kowalski-exp
Basebands tried: (none get me data connectivity)
LGP990hNAT-00-V25h-FID-CA-FEB-22-2012+0 (Original)
725 V10d (shows as Unknown in About Phone)
450 V20m SU660 (EDGE only)
OK, Correction...
Only the Wi-Fi connection was up. The cellular connection indicator was blue, which has led me to believe that cellular data connection was up as well. When Wi-Fi is disabled, the cellular connection indicator goes white and there's no data connectivity.
Furthermore, even though basic cellular connectivity was available for approx. 8 hours during the night, as soon as I left home and started moving it started dropping out. For example, I was only connected ~30% of the time for the past hour (and the reception along my usual route is normally great).
Toggling network-provided time doesn't seem to have an effect now, but the old tricks (toggling cellular connection, going into Airplane Mode, rebooting phone) seem to restore cellular connection for a brief period.
I also noticed that often when I would launch a data-using application (Internet browser, gmail app) cellular connectivity would be lost in a minute or so (saying No Service).
I've tried looking into "logcat -b radio" for ideas, but I don't quite understand what's happening here (willing to learn though).
Help...
I have installed CM7.2 (official CM) and CM10.1 (tonyp 5, oldbl) with dual boot and can now switch between the two ROMs. I have good cellular and data connectivity in CM7.2, but no data connectivity even after a fresh install of CM10.1.
I assume the baseband has nothing to do with this since both ROMs are using the same.
So, armed with a dual boot device, the n00b is ready to do troubleshooting! It only needs guidance now... Help?

Moto G (Dual Sim) Internet Connectivity Issues

Hi, I'm new here so forgive me if I do something wrong^^
First of all, I have a Moto G 2014, Dual Sim which is running on 5.1.1, to be more specific, this ROM. I was using this ROM for about 4 months already so that shouldn't be the issue. My problem is that after my phone connects to the internet, usually using H+. The connection to the internet is working perfectly fine, but after a while of not using the phone it loses the connection. It still tells me that it got a strong H+ connection, but nothing (browser, apps, anything) is able to connect to the internet. Enabling & disabling airplane mode usually fixes the problem. From time to time it also happens, usually when I lost some sort of wifi connection (regardless if I disabled wifi or I got out of range) it happens that it shows full connectivity but with an exclamation mark. This only goes away if I reboot or enable & disable airplane mode again.
Is this issue known/is there any solution to
I have been experiencing the exact same thing as of lately. I thought it was a byproduct of downgrading from (Stock) Marshmallow to (Stock) Lollipop (yes! it's happening even on stock ROM) where at times the WiFi losses connectivity when the phone had been sleeping for awhile...even though I have the "Keep WiFi on during sleep" option on under WiFi's advanced settings. I had no idea that it also happens with data connections ! ...as I don't use it (too expensive for me), now I'm uncertain what could be the cause. I can see how this would be an inconvenience if you use a lot of social media apps as I sometimes do not get my WhatsApp messages when this happens and sometimes I don't even receive my Hangouts messages until I open the app manually.
It's strange, at times when my phone sleeps for awhile and it losses connectivity and I wake it, it will reconnect just fine and other times it just goes into this state where it reconnects with full signal strength but with an exclamation mark next to the WiFi icon in the notification bar. When this happens, no matter what I try it stays in this state, I tried turning off WiFi and turning it back on, also forgetting the network and entering the info and reconnecting to it but none of that works. I didn't know that turning on and off airplane mode can help....I'll have to try that one, rebooting the phone was the only solution I found which is just inconvenient and somewhat annoying.
I too, am interested in a proper solution. I don't know why the phone ignores the "Keep WiFi on during sleep" option or why at times it connects but have not internet access! It should be noted that it's not a problem with the network, It's not due to an incorrect password or anything like that as I am the one that administers those things and when it happens other WiFi devices such as my Tablet PC, Laptop etc can connect and access the internet just fine and it only happens sometimes on the phone (Moto G 2014). This doesn't seem to happen in Marshmallow...but I hate Marshmallow and I can't remember having this issue on Lollipop post Marshmallow update (how I wish I had never tried out Marshmallow!!!), which is why I thought it was related to downgrading, .......did you downgrade ?
