mobile data enable problem - LG Optimus L9 P760, P765, P768, P769

on LG optimus L9 P760 with the latest android jb lg stock without any modifications (i just use the europe jb instead of the german version that was the preinstalled in my phone),
i have this strange problem, in my phone mobile data and wifi is always enabled, when i am in wifi range it connects normal to the wifi, when i go away from the wifi spot, it doesnt connects to the mobile data, even if i toggle on/off mobile data it still doesnt connects.
The solution to this is to make phone in airplane mode, then to switch to online state and then the mobile data is enabled.
Its really anoying cause everytime i have to select offline mode, then online and then the mobile data is working.
Anyone else has this issue ?

only me has this problem ??? i have to test with another sim card then, maybe it is a carrier problem...

Optimus L9 Wi-Fi problem .

I have an LG Optimus L9 P765 (Indian variant) with Stock ROM v10d on it.
WiFi on my set seems to be misbehaving. It connects to my network and works fine for sometime, but when I leave it unused for about say 5 minutes the mobile does not connects with my WiFi network.
In notification bar it shows that it is connected but actually there is no data transfer occurring.
Its very irritating as I don't get instant emails, whatsapp chats etc.
Is anybody else facing the same problem ? Please suggest any remedy for this problem.
Yeah, same problem here.
I've got an Indian P765 with V10d stock ROM as well. If left idle for sometime, the wi-fi seems to be connected but no data transfer occurs.
The small upward pointing triangle is shown on the wi-fi icon in the notification area, but the data transfer LED of the wi-fi modem doesn't blink, and so no webpage loads.
But if the wi-fi is being used continously, the problem doesn't occur.
Looking forward to a solution, thanks.
Edit: Reduced the Beacon Interval of the Wi-Fi modem to 100ms. The data connection is maintained now.
Problem solved. The phone's working fine afterall.
Before that happens go into wifi settings press the menu button hot advanced and turn the wifi sleeping policy off that is all that I can suggest

Beacon Interval of my WiFi modem is already 100ms.
Problem still persists.
Any solution anybody.
The only solution for now is to change WiFi sleep policy to Never instead of Always in WiFi settings.
But that turns on Mobile data or 3G (which ever you have) which is more battery consuming.
And there's no point of keeping a smartphone offline by disabling either WiFi or Mobile data.
P769BK has a different wifi issue. All 6 of mine have had this same issue.
Enable wifi and use if for a few hours.If wifi router looses internet access and you try to download an MMS it fails.
Disable wifi and try downloading MMS via cellular network it fails. Airplane mode toggle does not work.
A reboot is required to fix this. Very irritating when connected to a wifi network that has a bad connection.
Don't even get me started with wifi-calling. It just plain sucks on 4.x ROMs.
I use WidgetSoid which gives WIFI and 3G icon (also called power switches) on Home Screen and reconnecting is just a HALF SECOND deal for me. Its even quickly re-connectable from WiFi PowerSwitch in Notification Panel.
By the way, I did not notice this issue on my P765 (india) L9. Works well with Vodafone Mumbai 3G, and WiFi always connected even after idle time upto 2 hours mostly at home. Like they always say, results may vary.
Problem: WiFi is not useable
Hey Guys,
i've got a huge problem. I can't switch my WiFi on. The problem exists since a few months and I've tried to fix that by myself but my knowledge about programming is quite small. Please help me. WiFi is one of the most important functions. Is sendng it to LG-Support the only way to get that fixed?
Pls Pls Pls HELP ME!

hi friend,
You already managed to solve your problem?. I have a similar problem, did the bootload and installed cyanongenmod 10.2 for P760 and everything worked perfectly, after I turn off my smartphone realized I was not connecting the wifi and even tapping the power button it does not turn on, put your smartphone in order factory original and still the problem continues.
Can someone help me?

[Q] Mobile data not working after WiFi signal lost

Hi all,
bought for my wife Padfone S but when she leaves home WiFi, data does not automatically turn on.
If I turn off WiFi manually, data gets connected automatically, but if she just leave the range of WiFi with WiFi still on, but out of reach, the phone doesn't connect to 3G even if I'll turn WiFi off & on, data on & off - only what helps is restart of the phone - then connects to the mobile data without problem.
Phone is new, not rooted, stock ROM.
Shall I send to service?
Thanks for any tips.

My girlfriend and i both have this phone, her's had the same problem in one of the first software versions. Then a restart would help, but after the latest updates this problem doesn't occur anymore.

What software version you have?
I've bought the phone in East Asia and can't update any more. But played with the APN settings & actually it helped - the default settings was strange and now it works.

Tab S6 Wifi problems / Detects only a few or no wifi networks at all

As title says, just bought the device and it only picks up like 1 or 2 networks (not always) from like 10 available ones when I am at home. However, this problem is really apparent in my college dorms as I can't pick up any wifi network whatsoever making my tablet practically useless in dorms. Is this a software problem? or a hardware one? When I was at my home I was able to find my home network easily (but then again, it still didn't show up all the networks that shows on my phone)
p.s : Hotspot networks always show up in the wifi list, but when I switch the hotspot from using Data to using the WiFi the hotspot phone is connected to it disappears from the list
p.s.s : the tablet is running the latest update available for me (November 2019 / T860XXS1ASK2)
p.s.s.s : tried wiping cache and even hard formatting the device.
p.s.s.s.s : Its the Wifi only variant

Data connection not working when connected to wifi

Hi all,
i've got this big problem and i dunno how to solve it.
Stock rom, MIUI 12.0.3, no root, developer options active.
I ran into this annoying bug months ago, while trying to get my car's android auto working with my phone without using usb cable.
I managed to connect my Mi 8 lite with the car via wifi connection; made it enabling Android Auto developer options (otherwise it wolud let me connect only with cable). Unfortunately once connected everything doesn't work, because there is no data: while wifi is on AND connected, my phone doesn't "want" to use my mobile data, even if i force data use by setting "mobile data always on" option in developer options.
I noticed this is not a problem of my car's infotainmnet, infact it happens also if i connect my phone to my wifi network unplugging phone's line cable (and so internet data ) from my router. Also in this case, with phone mobile data always active, my phone will stay connected to my wifi (which has no internet) and won't use my mobile data.
Does anyone have any idea/suggestion or know what i'm doing wrong?
Thx in advance for reading
This topic is discussed here: https://forum.xda-developers.com/t/...iui-while-aa-is-connected-wirelessly.4252187/

Question Failing to switch to cellular data with "Mobile data always active" switched off

If I go into developer settings and switch off Mobile data always active (in an attempt to save a little power when the phone is on Wifi), I find the phone often doesn't enable data when I leave Wifi. I have to cycle airplane mode to make it do it.
Anyone else finding the same bug? Or even using this setting?
I've had dropped connection issues since day 1, with airplane mode being the only way to restore my connection. And this was with Mobile Data always active set to on.
Who is your Carrier??
Have you noticed similar issues even with mobile data always active?
When I go to building with no cellular and come back outside. The phone doesn't automatically reconnect to cellular, leaving me with no service. What a strange bug.

EE in the UK. Works fine almost all the time so far if I keep mobile data active.
Vodafone Romania, toggled the setting off in dev options as soon as I got the phone. Data switching works fine still.
Try going into the testing menu (dialer code *#*#4636#*#*), select phone information, select 3dot menu on top right corner, try switching around between Europe and automatic. I'm my case ,selecting Europe presented various weird connection issues , biggest of which was that the phone refused to connect to LTE unless I used "automatic".
