[Q] 3g connection will not stay up

So for the past 2 weeks I am having issues that basically render my phone unusable for 99% of the reasons I bought it. Posted a thread before but I think it got lost when the forums were having some instability around that time...
My 3g connection will NOT stay up. I did nothing to provoke this. No system changes. The sequence of events:
-Went out of the country with my phone on airplane mode the whole time
-Got back, a day or two later had an incorrect timestamp on my incoming SMS (they were showing up +3 hours)
-Called customer service, she activated a tester phone and confirmed that it was a system-side issue on the incoming SMS (somehow they were getting a timestamp from the system where my number is located, in Eastern time, while I am actually located in Pacific nowadays).
-Put in a trouble ticket after 2 hours trying to solve the SMS issue over the phone.
-Next day, my 3g connection begins dropping CONSTANTLY. As it stands, it won't stay connected more than 30 seconds. It will cycle to 1x sometimes, and then drop to a basic-service-only.
-Tried reinstalling my ROM several times to no effect.
-Started experiencing some very strange noises in SOME calls, such as it sounding like a chainsaw when the other person is talking. Happens very sporadically.
-Just today I found some instructions here for correcting my NAM settings, which were actually messed up as it turns out, but didn't fix anything.
At this point I actually have the phone unrooted and back to factory default everything, with no change. I've got a warranty replacement phone coming in shortly, but I'd still rather keep this one if I'm able to.
Is there anything I haven't tried that might be the case on my end? Has anyone seen this problem before? Has my phone antenna simply gone belly-up, or is this something that might still be fixed at some deep system-setting level, or with further calls to tech support?

So... I guess that's a no?

Had the same problem with my phone before I rooted my phone and starting to apply ROM's. I havent had a problem since. But when I had that problem, I would just keep turning on and off the 3g and it would stay for a while. It was just a quick fix but it worked. Off subject how did you unroot your phone and put it back top stock?

My phone just started doing this this yesterday. Whenever I reboot it, it'll come up, switch to 1x mode. After a while it'll try to switch to 3g mode, fail, switch to no service, and then either go to just basic voice with no data or back into 1x mode. I've tried updating the radio, switching roms, dialing *228, nothing seems to help.

Jager, instructions on a full reset are right here under section 6. I'm not sure why it's struck out. Definitely suggest poking around more first.
New phone's in and still having major connectivity issues. The SMS timestamp remains as it was, and I can't get (steadily) more than like 35kbps. I'll occasionally bump to 500kbps for a quick spurt, and then my connection will drop entirely and struggle to get back up to 35kbps. My wife's Incredible works perfectly fine in the exact same locations, too, so this is something that absolutely has to be on Verizon's side, specific to my line.

Me too
My phone has also been experiencing the loss of 3G service as well. I checked my wife's Moto Droid 1 and it was also having difficulty connecting as well. I called Verizon and they were absolutely no help whatsoever. I am either getting nothing or 1X in places where I have always had 3G. This is very frustrating. I have flashed 3 different ROMs (all of which have worked fine in the past), but the result always seems to be the same. Anyone else out there with this issue?

Someone help! Same issue! I can no longer get data....PERIOD. I have to stay connected to wifi, or I don't get my emails, internet, etc.
Need to fix this!

3G connection issues
I just got off the phone with Verizon Tech support. They are CONVINCED that it is an issue with my phone (and my wife's). Gee, how can 2 different phones, from different manufacturers have the SAME issue at the SAME time? Hmm, doesn't sound very promising to me.
They are sending out a replacement for my wife's Moto Droid to see if it is a phone issue (she has been having other issues with it anyway...). If hers improves, I may send mine back, but I don't want to have to unroot, etc. Plus I like the Super-Amoled screen . When did trouble-shooting turn to "replace the hardware first" ???
Regards!

This happened to me recently as well and was fixed with a factory reset.
I am rooted with S-off, so a normal factory reset via Menu->Settings->SD & Phone Storage-> Factory Data Reset didn't go well for me. Not sure of the exact reason, but I just followed the instructions in this post to restore: http://forum.xda-developers.com/showthread.php?t=786436
Programming your phone by dialing *228 is necessary afterwards as well, as khukman states below. Thanks for pointing that out.
After I completed this, I redid root, restored my nandroid backup and didn't lose a thing, plus my 3G is working again!
*A fair warning: Doing this formats the internal storage (emmc). I'd recommend backing up any photos, music, etc that you have stored on emmc before doing this!

So I tried the above suggestion about going back to completely stock 2.2 and I have the same results. On one hand, I am now back to S-ON and stock Froyo, so if I want to send it back to Verizon, they are none the wiser that I was rooted, but on the other hand I STILL HAVE CRAPPY 3G SERVICE!!! Man, I feel like I'm on AT&T or something LOL! I'll keep an eye on it for the rest of the day and see how it does and report back.

Back in 3G!!!!!
After getting back to stock Froyo, as described in the previous post, I was still unable to get a good 3G lock. I read in another thread where someone did a 'Factory Data Reset' and it took care of it. When you do this, you have to dial #228 and let it program your phone as it did the first time when you got it. Once I did this, I had (and still have) a solid lock on 3G like I used to. I think that it was one of the Sprint ROMs that screwed this up in the first place (the OP states that you have to backup your PRLs, etc. before installing, then re-install them afterwards). I can't remember if I did this or not, so it may be my fault after all, but regardless, I am thrilled that once again I have a connected smartphone thanks to the resources contained on XDA!
Regards!

I myself am now rocking a refurb that has no trouble at all... A complete revert to stock did absolutely nothing to resolve my trouble.
Though I didn't try doing a factory reset AFTER reinstalling the stock ROM. Hmm. Maybe there was something in the cache still. I suppose in my case I'll never really know, but I'm glad you guys were able to resolve the situation with your original hardware.

Did you follow the steps in the thread I posted above? Doing that should completely format and re-image your phone. Much more than just installing a stock ROM. I myself tried so many different variations of ROMs, radios, etc and nothing did the trick until I followed that thread.

[Q] "turning wi-fi on" but never connecting

Initially, I used the 4.0.4 system.
In the advance setting, MAC address and IP address are both unavailable.
All the other things work fine. And I have never dropped my GN. I don't
think this is due to a hardware issue.
I've tried almost everything I can, flashing Radios, flashing kernels, changing
to other third party ROMs, take off the battery, ..., but none works.
Now, I've flashed to the new JB 4.1. It still not works.
I used to be google fans. But Google disappoints me this time. Maybe I should
blame Samsung.
Anyone who can help me I'll be very very grateful.
Kevin

1. Can you see any networks at all?
2. Have you used the correct password for the network?
3. Have you set the correct security for the network?
4. Have anything been changed on the network?

Thanks for reply.
I cannot see any networks at all, except "turning wi-fi on ..."
I've tried both at home and at workplace, the issue is still there.
My wife's phone works well. I've also reset the router, but it still
does not work.

Then you probably have a hardware failure, if you still have a warranty on your device you should send it back for repairs.

Yes, I've fully wiped. And I've flashed back to 4.0.1, 4.0.2, 4.0.4,
but none works.
I've seached on the forum but seems no good solution. Sigh...

Then you have a hardware failure. Only resolve is a repair. If you still have warranty you can do a claim on that.
There are a couple other threads about the same issue, where the solution was your change the board the wifi sits on.
Swiftkey'ed on my CM9 Galaxy Nexus

I have this issue and i can only solve it by restarting many times and sometimes having to pull the battery out.

WiFi Disconnecting Issue

Perhaps the most annoying thing is that I had stock rooted....then I switched to Liquid Smooth v2.2 (I'm just saying because the problem has spanned across both ROMs....thus it can't be a ROM issue)
But pretty much, when the WiFi is connected, sometimes it'll cut out...and go to 3G.....then maybe it'll come back again, and maybe it doesnt.
Only time the problem gets manually fixed is if I go to the pulldown menu and click on WiFi (the WiFi button is already lit, but I unclick it, then click it again) and then it'll come back.
But if I go to settings --> WiFi, it will force close. Only way to fix it is from the pulldown menu.
My WiFi policy is set to "never sleep" which is fine because it goes into sleep mode when I use DS Battery Saver.
Can someone help me, so that it doesn't automatically disconnect? Thanks!!

I'd go back to full stock
[ROM/RESTORE][!MB1 OTA!](3-05)Quick Return to UNROOTED STOCK WITH FLASH COUNT RESET
and see how things go, I've heard that using root toolkit can cause weird wifi problems if that was used to achieve root.
I'd stay on stock for a few days. If wifi stays wonky then bring it in to sprint. if not then try to root again. (if you used the toolkit then use the method outlined by qbking777 - you can find his channel on youtube)
Good luck

Well this problem doesn't occur in other home's WiFi, only mine.
And it's been recent, probably like 2 months.

Ah, well that would have been good to mention before
things i would check:
It may be due to your security type on your router.
I have mine set to WPA2/PSK; you might play with that.
any new apps installed on your phone
maybe a firmware update to the router if you've updated the modem on your phone
if not, maybe update the modem on your phone
if all else fails. I'd still go all the way back to stock and check it out. because that gives you a know starting point with not augmentation.

Ok so I had this same problem a while back and after a little Google-fu I found a solution.
I found that people were able to fix it by changing the SSID of their wireless access point. I changed the SSID that my router was broadcasting so it would have ONLY alphabetical characters (went from MOTOROLA-8472J to MOTOROLA) and the problem magically fixed itself.
Dont know why this happened, but it seems like its a problem across Android, as opposed to a single device
Hope this helps :thumbup:

Mine is like JMF23 but I'll change it to something else.

Problem isn't just my router. I just went to a friend's and it's the same thing. I am extremely frustrated and I have no idea what to do.
The WiFi keeps connecting...then disconnects. When I go to the settings, the IU freezes. I can only enable WiFi again from the pulldown menu.

Did you try going back to full stock as jdelano mentioned above?

WIFI gone to hell

Has anyone else experience their WIFI connection almost completely stop working? For the last few days either I get no connectivity at all or very slow, but every now and then for a few minutes it will run at normal speeds.
I'm stock, rooted, no custom recovery or 2nd bootloader. I've rebooted the kindle and my router multiple times. I've done a full factory reset on the Kindle. None of that helped. There's 3 laptops, 2 other tablets, and 2 phone all running fine on the WIFI so I don't think it's the router.
If anyone has any suggestions. I'd appreciate it.

Have you done any other modifications other than rooting?

I've got the google services installed to get the Play Store working, and installed NOVA launcher. I think that's all.

Well, I thought it may be something with the drivers gone funny, so I finally got around to getting 2nd bootloader and recovery going. I tried CM10, I tried Hashcode's stock ROM, and I tried the full restore from the KFHD First Aide tool. All the same results. I'll get intermittent bursts of full speed, but for the most part every web page, market request or attempt to stream something times out.
When I look at the WIFI settings in the kindle, it pretty consistently says 39Mb link speed. My phone is connecting at 26Mps, but everything works no problem as do all the other devices.
I know I'm heading into O/T territory, but does anyone know what Router Settings to check for that may be limiting just one device? Failing that I'm going to have to return to stock and see if I can get some help from Amazon.
Thanks in advance!

I'm also having some wifi issues like you. Mine's 8.4.3, rooted, with google play store and a few other things. Like you, all my wireless settings seem to be ok, several other devices use the wifi without any problems. And like you, I've had CM 10.1 installed in the past and I'm back on the stock Amazon rom.
One hunch that I had yesterday was the following: I bought a cover for my Kindle that can cover the back and front of the kindle. When I use it normally, I fold the front cover around to the back of the device, meaning there's a double cover on the back when in use. I thought to myself, maybe the cover is blocking the wifi signal or something... I then tried changing the cover to "kickstand" mode, so that it wasn't against the back of the device. It seemed to help, but I still need to do more testing.
If you have a cover then maybe try taking it off and testing the wifi. If not then I'm out of ideas, but I'm not sure how it could be a software problem, since you've tried different ROMs with the same results.

Apparently, after a quick google search, it looks like a lot of people are having wifi problems with the kindle fire HD. Perhaps the following thread will help: http://www.mobileread.com/forums/showthread.php?t=210002. It mentions changing some router settings. I'll try it on mine when I get home.

Make sure that QoS is disabled on your router.

Thanks for the suggestions. No help unfortunately.
I need to get somewhere I can try connecting to a different router. If that's still unusable, I think it's time for the service call.

WiFi on the G3 headaches [SOLVED]

I just got an LG G3 last friday (Black Friday) on T-Mobile (got tired of Sprint). Anyway for the most part this phone has been great. A minor glitch with a game (possibly from porting it's data over from my S3). The main problem I have is with the WiFi.
First off WiFi calling sucks. If I don't have 3 or more bars on my WiFi connection the call gets fuzzy. During one call that was clear it just randomly dropped. So that isn't cool.
Secondly, if I connect to a WiFi network at home or work or where-ever and then go somewhere else and come back or go to another place with a network I want to connect to it won't connect at all. It will show all the networks and give me the option to connect. But instead of connecting it will try to connect for a long while and then just give up. I cannot get connected again until I reboot.
I have tried the suggestions found on this thread (and other places): http://forum.xda-developers.com/lg-g3/help/lg-g3-wifi-issues-t2829811
No luck with those suggestions. Which include the following:
Turn off and back on the wifi radio.
Disabling the "wifi signal is weak" option.
Disabling the battery saving for wifi.
Forgetting the network (my network list was automatically imported from my Google account).
Installing the "WiFi Manager" app and enabling the 5GHz channels (US) and changing 2.4GHz channels to "Complete".
Made sure that "Internet unavailable" option is disabled.
Made sure that "Keep Wi-Fi on when screen is off" is set to "Yes".
Disabling NFC.
Disabling BlueTooth.
Disabling Wi-Fi calling.
I don't have problems with a weak signal. So I am perplexed. My Samsung Galaxy S3 worked just fine on these networks. Restarting always seems to allow me to connect again. But I shouldn't have to restart every time I want to connect to WiFi.
All of my other wireless devices connect just fine in the household (a PS3, my fiance's Moto X, my old S3, MacBook Pro, Lenovo Windows 8 laptop, an HP running Ubuntu 14.10, and another Lenovo running Ubuntu 13.04).
Why is an older model phone doing so much better than the G3? Both phones are rooted (old and new). Does anyone have a fix? My phone is currently running LG's factory rom "D85110m". That is with Android 4.4.2 (my old S3 is on a cyanogen rom of the 4.4.x series as well).
Please help me fix this. Otherwise I might return it for an S5.
Thanks!
**** Update ****
Per my below post, it seems I have fixed my problem. I ended up doing two factory resets, unrooted, and did a final factory reset to fix the problem. Then I switched to the PurpleDrake method to root it the second time (and it worked really well without any issues).
Good luck everyone!
**** End of Update ****

Try to factory reset the phone. I don't know what version you are on but I assume its 10m

It is on 10m. Do I need to unroot before I do the factory reset? I have never had to do one before.

So it appears that doing a factory reset does not fix it. I guess I am taking it back and having them replace it. And I will demand it be a brand new one since I just got this phone a little over a week ago.

SOLVED!!!!
Ok, so I finally got it fixed. Albeit accidentally as I didn't expect it to be fixed at this point.
Here is what I ended up doing:
Two factory resets.
Unrooted the phone (via these instructions: http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html).
One last factory reset at T-Mobile store by me (because they forced me to).
The wifi did not start working correctly again until after that very last factory reset that I did. The unroot process also does a factory reset. But, and this may be key, it downgraded my phone to 10c from 10m in the process. I then did an OTA to 10m after the final reset.
I unrooted it because T-Mobile's diag software detected it was rooted and said that made the warranty invalid. And after I unrooted it I took the phone back to the store and demonstrated the problem to the employee that sold me the phone in the first place. He tested it for about 10 minutes and came to the same conclusion as myself. He then had to go to his manager to approve the replacement.
They got out the new phone to replace it with then the manage told me that he was required to have us to one more factory reset. So I went into the settings on the phone and did one last reset. And for some reason, since this point, the wifi problem has gone away.
I think it is possible that something I did to the phone caused the problem in the first place. But since I did so much to it in the first few days (rooted and installed a ton of apps) I am not entirely sure. My two current theories are it was either caused by this malware infected flashlight app I installed that kept popping up the Play Store to install a particular app. Or it was caused by the rooting method I used.
The original rooting method I used was "Stump Root". So the second time around I used the PurpleDrake method. This is a tiny bit more tedious, but very effective and it didn't seem to break anything. Further, when I installed TWRP I made sure that I grabbed the recommended image for it that is specifically for the US T-Mobile LG G3 device and installed that using Flashify.
After I got it safely rooted I tested the crud out of it and it seems to be working fine.
One last thought. It is possible that somehow Titanium backup caused the problem when I restored text and call logs. But I seriously doubt it.
Anyway, if anyone has any questions for me about this please shoot me a message. I am more than happy to help.
Thanks,
Patrick
