Looses signal once per day, needs restart. (PACMAN v21.0) - LG Optimus 3D

Since I put the PACMANROM v21.0 - JB 4.2.2 on my p920, I loose connection to the network at least once per day.
Usually it happens after a long idle time and recharging over night and randomly once per day on normal use.
It did not happen on Stock ICS 4.0.4.
I read it has to do with 4.2.2 and/or 4.4.1 mostly .(?)
I found many threads about this "problem" (mostly on Nexus(?)) but no solution to it.
And I found the tool "3G Reconnect", which sadly wont work on 4.2.x.
I tried "Network Signal Refresher", but it doesnt recover any signal.
Even the helpfile says that no android app is capable of this...
Is there any other option except restarting the device ?
-Selecting airplane mode wont help.
-Starting a call ends up in "call got ended" and doesnt help.
-Trying to manually select a network and/or reconnect to it fails.
I can see that Im not alone and I wonder why there isnt another app like "3G Reconnect" for 4.2.x and upwards. Or is this app considered to be just a shortcut to the "select network" menu anyway ? (means, not a "special" app?) And why cant an app do somekind of a reset, similar to switch on/off phone ?
If there is anything else I can do instead of a reboot, feel free to tell me. :angel:

Wifi connection connected but won't load pages

It said connected in the wifi setting and it shows bars but it just won't load any website in the browser .. anyone got a fix for this?
I have the same issue. Tried different combinations of restarting wifi, turning on/off cell data, on/off wifi calling, etc... all with no result. I've also tried on different networks (both public and private)-- it'd start working for a while and then all of a sudden stop and never work again.
Seems similar to the problem here: forums. t-mobile.c om/t5/T-Mobile-G2x/G2x-WiFi-DNS-issue-not-the-4G-switching-one/m-p/831439 (sorry there's a new user no link restriction)
Does anyone have any suggestions?
Thanks

is it specific to the browser or can you not move any data?
Idk, whenever I have had problems connecting to the tmo network, which is a separate issue.. it was always that wifi calling was still on even tho wifi was turned off. Every time I had probs w/ data on tmo network, it's been wifi calling.. Your case seems to be diff tho.
Is it specific to just your network or all other networks? Try shutting off wifi, reboot... then turn it on again? Idk.. just tossing out ideas.
Some found the root cause and I am posting his finding as I do have the same issue and can reproduce the error:
I think I have discovered a new WiFi-related bug in the G2x's software. I have witnessed this occurring on my phone, and have also reproduced it on a store demo unit. I believe it is unrelated to the switching-to-4G problem people are having with the My Account app, since it occurs even if I have set up the Google account on first boot after a factory reset.
The details of the problem are:
- Every so often, the phone randomly gets stuck in a state where it is not able to initiate any new connections that are made using a DNS name. Attempting to navigate to a web site, h**p://w*w.google.c*m for example, will result in a generic failure message.
- However, attempting to connect directly to an IP address instead of a DNS name works perfectly. For example, navigating to 74.125.225.16 will work fine and will load the Google home page.
- When the phone is in this state, using a DNS lookup tool such as "DNS Lookup" from the Marketplace *will* work, even when using the default DNS server address that the DHCP server is giving the phone.
- The problem has occurred for me when data is off and WiFi is on. I do not know if data being off is a requirement, since this is the way I usually run the phone, so this may be coincidental.
- Switching WiFi off and back on again will *sometimes* work to solve the problem, but sometimes will not. When this doesn't work, switching WiFi off, then switching data on, then back off again, and then finally switching WiFi back on again will occasionally correct the problem. However, I have seen situations where none of these things worked, and the only way to get DNS working again was to factory reset the phone.
- I haven't figured out the exact pattern yet, but this issue seems to occur when the phone has been inactive for a certain period of time. I have often discovered that the phone is in this state upon waking up in the morning after leaving the phone on the charger overnight.
- I have, however, found a method to reproduce the problem that seems to work fairly consistently:
1. Turn WiFi on, and data off.
2. Power cycle the phone.
3. When the phone starts up, start the browser and attempt to browse to w*w.google.c*m. It should fail.
4. Try to browse to 74.125.225.16. It should work.
Just wanted to get this issue in the forums to see how many others have been noticing the same thing.
I know that once the device has less than 10% battery it automatically turns the WiFi off to save battery power. Were the devices this was happening on have a low battery?
Fully charged. It even happens when pluged in with the charger.
My Wifi wouldn't even work if I froze it with Bloat Freezer. It has to run in the background for wifi to work. I found that Wifi can get really inconsistent with it disabled.

Same problem here. After about 30 minutes of being idle, as soon as I pick up the phone it tries to connect 2g/4g. The log are saying theres no connection, so it appears that wifi its going to sleep and not waking up so android is trying to connect 2g/4g
Really starting to be a pain
I have frozen the bloat, and I think the problem is getting worse.
Toggle airplane mode is a quick workaround to get wifi to wake up

Same thing happened to me, I did 2 factory resets, and it seems it has been fixed, don't really know what causes it.

This may or may not be related, but...
It looks like I found a hacky fix for the dns/wifi/4g bug: install "Set DNS" from the market.
Now when I go into market, and display my downloaded apps, it jumps from wifi to 4g then back to wifi as it should, fast.
Whether or not it should even do go to 4g is debatable, all I can say is my 2 Galaxy Tabs had the same behavior.
If everyones connectivity issues are really due to the DNS settings getting wiped out, then this will work around the problem until I/we find the location of the actual bug.
Would you guys having this problem also post it here?
http://www.lgforum.com/forum/boards/general/lg/topics/g2x-wifi-problems
Thanks.
I figure the more people that post there, the more the chances are of LG fixing it quickly.
Work around:
enable airplane mode
reboot
enable wifi
wait a few seconds after the wifi connects, background crap stops
disable airplane mode.
The set dns app looks like a winner. Haven't tried it but that's what's
wrong.
The freezing and other suggestions are all useless crap.
Updates...
I did a factory reset and installed JuiceDefender (I don't know which one worked) but it seems to be all fine now... will update if things become problematic again
I've been having this problem as well. I've always been able to fix it by toggling WiFi off and back on again. I downloaded SetDNS and when it happened again last night I tried that and it worked great.
Glad to see it's a software problem and not a hardware problem.
same problem here. hopefully it won't happen in cyanogen mod

This fixed the problem, at least until the next time I reboot my phone
How do you use SetDNS? This software bug in G2X reboots my router (DGL-4500) sometimes.
Question bout SetDNS app
Does the phone have to be rooted to use the setdns app? I try to use it but it says "Cannot get root. App will not function."

[Q] Data connection stops when in sleep/idle.

Since I upgraded to Jellybean I have a problem with my data connection while my phone is idle.
This disconnecting of data only happens when I use my Data, and not with WI-FI.
When I don't touch my phone for about 15-30 minutes, I won't recieve any push-messages (Whatsapp).
I searched for this problem, and do believe the problem lies with the idleing.
When my phone is idle I think my Data will shut down and will only reconnect when I wake my screen.
Sometimes it will recieve the messages at random moments, maybe when the data gets refreshed.
This makes my phone pretty much unusable, because I want to recieve my messages when I need them.
Does anybody know a fix or a ROM where this "data sleep" is disabled?

Hi!
I was about to post kind of the same question about phone idle!
I am experiencing the same problem when my phone goes to idle!
I also loose the wifi when phone screen is off...
Everytime i wake the phone, i dont see the wifi signal... then, after maybe 2 sec, wifi (or mobile data) is connecting, and i recieve mails & things...
I think that's why i have a bigger battery life in JB instead of ICS ...
I experienced this bug with a few ROMs, il PA, TSM, CNA, etc... (stock or custom kernel...)
Any help will be welcome...

I've tried lots of roms and kernels, including GB, ICS, JB. I also tried different radio's (for i9023). I did a full wipe for every Rom install.
I don't have any problems using wifi, so I think your problem is different.
I use WhatsApp Messenger. When my phone is in sleep mode, I can't get any messages when using data connection. No problems on wifi so far. I followed this faq for WhatsApp problems. It's still not working properly.
I'm starting to think it's hardware related. Any help is appreciated.
I think I've got the same problem. Since I've flashed Androxide JB, my phone isn't syncing on data. I did revert to ICS, but it didn't help.
On wifi, background sync is working fine.
I tried different carriers, roms, radio, kernel. All of them didn't work.
Any solution available?
I also experienced this problem after flashing Androxide JB. Different SIM card doesn't work either.
I am also having this problem. Have install slim bean 3.0. connection seems to drop when the phone goes idle. anyone found a fix?

In settings, go WIFI, hit menu soft key, advanced and there should be a menu called "Keep Wi-Fi on during sleep", click it and set your choice.

AOKP JB 4.1.2 Mobile data dropping and not reconnecting

I’m currently using AOKP Jellybean 4.1.2, the supposedly stable, reliable milestone version found here: http://forum.xda-developers.com/showthread.php?t=1804223
I'll try to be as thorough as possible in hopes that someone will respond and know what to do. I apologize in advance for being long-winded.
I didn’t have any issues last night when I first flashed the rom. I was able to watch youtube videos using the mobile data. I was also able to turn on wifi to sync some files from my dropbox to my phone, and then turn off the wifi with no issues. However, today after connecting to a wifi network to download a few things and browse the web, I disconnected from the wireless network and the mobile data curiously did not start up again. I DO have cellular service (3-4 bars), and I can make phone calls and check my voicemail by pressing and holding 1 on the keypad, but my mobile data doesn’t work. I looked around for some solutions, and I've since restarted my device several times, tried toggling airplane mode on and off, and did several combinations of reboots with airplane on/off and no dice.
Everytime I use the toggle in the notificaton bar area to turn off wifi, my internet connection goes with it. It says “no internet connection” in the notification background at the bottom of the screen. Once I turn wifi on, I get my internet back and it says “at&t” at the bottom, but I don’t actually get mobile data because apps like “At&t Visual Voicemail” which require mobile data to function don’t work.
I tried flashing the 1.85 radio to see if it would connect to mobile data, and same issue persisted after reboot and dalvik/cache clean. After that failed, I flashed the 2.20 radio + RIL zip files seperately (which is what I understand came with the rom), and still no dice.
For reference, my HTC One X was rooted with 1.73 firmware (I never tried to update it until last night). I did the CID spoof method to unlock my bootloader, and installed the newest version of TWRP on it. I flashed the rom and the gapps package. I used TiBu to restore program settings and a handful of my out of market apps, and the rest of my purchased apps downloaded automatically from the market after connecting with my google account. I had literally just finished reinstalling the last of my apps today via wifi when this issue started to happen.
I'd really prefer a practical method of getting this fixed that doesn't involve starting over with a fresh rom install. Reflashing at this point would be something of a nuisance since I don’t have much free time to begin with. And hey, it took a long time to load up all of my apps just right
However, if there is no other fix that anyone is aware of, I guess I could reflash or in the worst case try a different rom. It’s a shame because the rom otherwise is really smooth and runs great on the phone, in addition to not using a whole lot of resources and having a decent battery life.
Thanks in advance for any suggestions and solutions.
Here is an image of my battery drain screen showing what my mobile data is supposedly doing despite not being able to get a true data connection. Even with my wifi off, there is supposedly medium mobile signal.
And attached is another image of what happens when I turn my wifi off. I pulled the notification pane down and you can see that it says "no internet connection" at the bottom. Also, you can't really see it in that cap, but the mobile data bars behind the notification area are colored white, and there isn't any "H+", "4G", or "LTE" notifiers visible.
Edit: Attached a third image showing the "white" signal bars (i.e. no data connection). Yes, my mobile data is turned on, and I'm obviously not in airplane mode.
I figured it out eventually for anyone interested... Apparently the APN were not set. They existed on the APN list but were not visible due to a glitch in the ROM I guess. I had to add a custom APN and then the other ones suddenly appeared.
Thanks anyway.

[Q] Wifi and post-call issue

Hi
I bought this phone 3 months ago and have been going through 2 major issues which have become a pain in the **s.
1) Most of the times, while making a call the screen freezes and the timer is stuck on 00:00, and the UI stops responding to any inputs, which means i cannot use In-Call features. If there's a need to make another call after the previous one then the phone needs to be locked and unlocked since the UI doesn't respond to anything without lock/unlock trick.
2) This one is more annoying and it's about Wi-Fi.
When I connect my phone to the wifi and leave it idle for say 5-10 minutes (provided there's no data being exchanged between the phone and router) and then try to open a website, it just doesn't open it with any browser and all other applications which require internet access stop working.
I have tried changing routers and even tried keeping my phone next to the router but the problem still remains. STAMINA mode is always disabled and "Keep wifi on during sleep" is set to "Always" and "WiFi optimisation" option is also unchecked. To make it more clear, the wifi icon is still displayed after idle time of 5-10 minutes on the top right corner with the uplink arrow lighted up and the downlink arrow not lighting at all.
Please reply if somebody else has the same problem and has any solution to it.
I am on stock ROM, with the latest official update 15.3.A.1.14, everything as it is.
Faced same issues for a while, after unlocking bootloader, rooting and installing a generic firmware(europe CE), issues are gone. Original firmware was with Vodafone branding and a lot of crapware.

Android 10 - wifi sleeping while screen locked

Hi guys!
I did a lot of googling and searching through XDA, but never found a solution for my problem, so I might as well try it here.
Recently I updated my Sony Xperia X Compact to AOSP 10. Now when I am connected to wifi (and it does NOT matter whether it is 2.4/5GHz or IPv4/IPv6, I tried everything) and my screen is locked, my system seems to put the wifi connection into some kind of battery saving mode. Notifications then will hardly come through. You can also see this in WhatsApp Web - every two minutes or so, "Phone not connected" will show up, and messages take up to 2 or 3 mins to get delivered. Then I can use Whatsapp Web normally for 30 secs, after which my phone seems to disconnect again. If I unlock my screen, WhatsApp Web will immediately (!) start working normally again, also missing notifications (e.g. Signal) will then come through.
While of course this might be a ROM bug, I am at least 100% sure it IS ROM-related, as I used exactly the same phone with exactly the same router without any problems while on Android 9 LineageOS.
Another interesting thing - if I charge my phone, during charging WhatsApp Web works completely without problems. The moment i UNPLUG the phone, wifi gets somewhat throttled agian.
Does anybody know a working solution for this? I do not have the option "Disable wifi sleep" or something similar - i believe Google has dropped this option somewhere around Pie.
Thanks in advance!

AFAIK there are kind of wifi energy saving options on some devices. But IDK if you can enable or disable wifi when phone is locked
