Unreliable data connection - T-Mobile LG G2x

I'm having this weird problem with my G2x where my connection to T-Mobile's data servers has a mind of its own. Sometimes, I'll have no problem booting up into (or switching from WiFi into) a stable data connection, but at others, I can't find for the life of me a way to get it working correctly/normally.
I've had this with every ROM/kernel I've installed since I rooted it on day 1. I don't remember if I had any problems back on stock ROM and kernel, but it looks like I'll soon be unrooting and restoring to find out.
Another (possibly-related?) symptom I have is that my APN settings are forever cursed to be blank. There are no settings listed and I can't get any ones that I add to save. I got an APN manager app from the market that showed I had the proper APN settings up and running. Therefore, I'm assuming this is not the cause of the problem; otherwise, how come it is indeed connected to data services? Correct me if I'm wrong.
I'd also just like to say I'm not the only one experiencing this. I've seen a handful of other posts throughout the G2x threads that are reporting the same connectivity issues.
Any ideas what's going on? I've tried most of the basic stuff:clearing cach, rebooting, wiping Dalvik cache, fixing permissions, etc. I'm starting to believe that there was a batch of G2x's that came with manufacturer defects that were unknown until now.
EDIT: Solved this problem myself. see this post for more info.

Wifi problem just reared its ugly head after 48 hours with official Froyo

I may have bragged too soon on good ol' official Froyo. I had a smooth install and the only problem I've noticed is the messed up Quick Office deal like most others. Today I just had another problem start.
I've been using my secured home wifi network fine, but for some reason the Captivate will no longer connect to it. I've tried doing a battery pull, turning the phone off and back on, and even completely removing the home network from the list and then putting it back in. I'm sure the password is correct. It just sits there, saying "Obtaining IP address". It retries several attempts, and eventually gives up and lists my home network in the list as "Disabled"
This is significant suckage!

I had similar problem try unplugging router and plugging back in
Bless your heart! That did it! I just read on the AT&T forums that someone else had the exact same problem and he did a factory reset of his phone which fixed it. I was hoping I wouldn't have to go there
I found an easy solution to the problem. Open Allshare, then you should be good to go.
After opening Allshare, hit connect.
Yes sometimes power cycling the router is all that is needed. I notice this with laptop sometimes too.

Yeah that was me...
I tried everything else before the factory reset, but the reset fixed it, now I've got wi-fi with no problems
If you do a factory reset, I realize you have to reinstall all your apps, but what about the ones I paid for? Will I have to purchase those again? I'm thinking of doing one just because I think it will smooth things out and get rid of a couple of weird quirks like the Quick Office icon problem.

anything you purchase with your google account is tied to your google account. you dont have to re-buy those...for any phone that you log into your google account.
Has anyone tried my fix? Sure beats having tofactory reset...I'm just sayin.

It works, but you have to do it every time, so it's more of a workaround than a fix.
I had an issue with connecting to one of my work wifi routers (would just sit there saying 'obtaining IP address' but never would connect) and could not fix it until I tried using "FXR WiFi Fix and rescue" app from the market. Free app, will erase ALL of your saved WiFi data so make sure you have your passwords for encrypted networks, but this fixed it with one click and a reboot. Seems to connect faster to the networks now as well. I had a similar problem after the previous update that went out OTA and had to reset the phone for that one.
I thought about trying this app, as my wifi issue returned today. I thought I had gotten rid of it by doing the factory reset, but alas it's back. I'm really contemplating a custom ROM more and more every day. I just don't know which one to go with that will provide everything I need. This app sure asks for a lot of permissions, so I'm sort of leary about istalling it.
Welp, I bit the bullet and tried the FXR app. No dice for me. I'm waiting for the wife to get done surfing so I can try a router power cycle. If that doesn't work, I'm looking at my second factory reset in less than a week. Froyo, you suck! I never had wifi issues until I upgraded to 2.2. What I can't understand is, why some of my issues are better, yet some are worse. Is it that difficult for these idiots to figure it out?
Just going to throw something out there, that I noticed yesterday. I'm on a custom ROM, but I noticed some pretty flaky results to my wifi, but only when I was using the modified TouchWiz launcher. The wifi had trouble connecting, and wouldn't sleep. The notification dropdown widget wouldn't control it. Then I switched to Go Launcher EX, and the behavior stopped.
Check another launcher, and see if that makes a difference. Sure, it's a longshot, but I'll be interested to see if the stock TW has the same issue as the modded version.
I was having the same wifi problem after updating firmware to official 2.2 kb1. I used fxr and now wifi connection works great.

[Q] Losing my APN constantly !! ?

Hi-
I have the T-Mobile LG G2x. I have been using and updating my ROM weekly with the latest port of MIUI ( WhiteHawkx's version ) -- currently on 1.12.01 [12.02.2011]. I have a horible time keeping my APN up. I can make calls of course, and I can use data, for a while, but then after 10 - 20 minutes I lose my APN and no more data. I have tried the "Power Button and Vol. Down" trick, but even tho that will fix the data connection, it is only for a short while and I will lose it again. There is NO rhym or reason as to why this is happening.
Am I the only one that is having this serious issue ?? And it is not my data being throttled. When it happens it is gone completely until I somehow force it to restart.
Any thoughts on how to resolve this ?? Are other people having this issue also ?? It happens to me about 30 times a day.
One bit of information: If someone pushes me a packet of data (like a whatApp message or KiK message) my APN will start working again for a little while. But only if they pushed it to me. otherwise data is still not going out. And I do NOT have anything set to sleep.
Thanks for any insight !!
John

(not specific, but I posted a similar issue in this thread)
These are just from the first couple of pages from the General and Q & A forums of topics with people having issues with one or the other:
APNs lost
Data dropping
Losing network connections
etc
Certain roms seem to be slightly better, but people have had issues (like me) with everything from stock, to CM7, to MIUI. This is more than just a coincidence. I think LG must have shipped a batch of POS G2xs. And if you have NEVER had an issue, then count yourself as lucky.
Thank you for the reply..... but my issue seems a bit different. I do not have any trouble with my signal or cell talk dropping. My phone never drops a call. This is only data related. Like going to the Android market or using any app like messenger, whatapps, kik, Skype, ect.... anything that uses data will eventually stop sending, until I reboot. my SIM card is fine.
Any other ideas ?
Ah, sorry I misunderstood. You might want to check out a different kernel then.
im having this issue as well
except i only lose my apns if i shut off than turn back on my phone, im using rg2x

next time ask in the ROM's Thread.
but as far as i know it does not. im using build 31 and its working fine.
try pulling out the battery for a few seconds then putting it back in and booting up.
Same here...data working fine in aokp.
Forgot to mention that there is an issue with data dropping in ALL 4.04 ROMs, including other phones.

The issue behind this here is that for whatever reason, the APN settings always seem to get lost. Sometimes the actually load properly and boom data. Then perhaps you leave wifi on and then most (at least all of the ICS roms I've used) drop the APN.The APN is what handles the data verification.
EDIT: As of recently, I have discovered that data is working fairly well on AOKP. I just reset the APN under its menu, then rebooted. Make sure you're running the correct RIL; it does help. Besides that, I've found that fix permission sometimes screws with APN recovery. So fix permissions, reset APN, and enjoy data coming back.

Permanent Fix for intermittent data issue on CM9/10/AOSP 4.0+ based ROMs

After months of having this reoccurring issue myself, I FINALLY figured out a solution. It had gotten so bad on mine that wiping the rom won't matter... the only solution was to wait for several minutes/hours until it returned or switch to a Sense-based or a GB rom. This fix should appeal to those who had to return to older roms due this issue driving them insane!
Let's clear up a few things first.. to those having this issue and being able to restore data by going into airplane mode might wanna invest in a new sim card. Best to go into a retail location and pick one out yourself. The newest ones (model number TM9177 or higher) work the best and have the fewest data drop offs. That should fix a lot of users intermittent data issues from returning.
If you still have data issues and already have a newer model sim card (TM9177 or higher) OR have data issues that don't get fixed after a reboot, switching into airplane mode, wiping, normally have to wait a long time for it to return on its own, etc.... then this part will fix it. :highfive:
Go to home, menu, settings, wireless & networks, more, mobile networks, access point names, menu, and FINALLY add a new apn. Chose whatever for name of apn (maybe tmobile alternate, tmobile 2, or whatever), the next line, the actual apn, with be "wap.voicestream.com" (no quotes, duh). Next add this line to MMSC... "http://mms.msg.eng.t-mobile.com/mms/wapenc". Everything else should be left as is. Now hit menu, save apn. This new apn seems to work with all features I've tried... text messaging, full data access, same speed as default epc.tmobile.com apn, tethering, etc. Haven't tried MMS but the settings for that line is there in our alternate apn we just made. Please post results on that if anyone still uses that feature So... that's it. The old apn works nicely and you say GO TO HELL! to the annoying data icon flashing on and off forever!
Be sure to post your results/experiences to confirm but it seems to be gone on 4 other MT4GS CM9/10 users besides my own. I REALLY HOPE y'all are as happy with this fix as much my family, friends, co workers, and I are! Do forget to use the thanks button
Also... you can try "internet.voicestream.com" for an additional apn. I'm not sure if MMS will work on that one even with the MMCS set as "http://mms.msg.eng.t-mobile.com/mms/wapenc" but it's work a try. If anyone wants to check it out is welcome to. Again... post your results. I'm not sure how long tmobile will leave these old apns active but I bet it's longer than anyone will be still using this model lol! Enjoy!
I've been one of the lucky ones not to have had this problem but if this fixes the issue of those that have been, this is one NIIIICE CATCH! GOOD WORK, sino8r!!
I'm very anxious to hear how this works out for everyone!
Intermittent Data 3G 4G Loss Disconnect
Wow, Thanks. I've been fighting with this all day.
I've been running SilverL CM 10.1 for a couple of weeks and today suddenly lost my T-Mobile data connection.
I tried many solutions (I wish I'd found this thread sooner). Wiping Cache, Fix Permissions, Reflashed, different Kernals, different loads. Going back to Gingerbread worked, but I lost the data when I went back to ICS/JB.
There was even another thread that was close with deleting all APNs and creating a new one, but the settings still weren't there.
This took care of it right away.
THANKS !!!!

Tested it with 2 diffrent JB roms fixed data problem in about 10 seconds from selectign new APN. Data speeds are back to normal! Will update if anything changes.
After several days even weeks of no issue then suddenly I get data issues again so I go back to mobile networks to find the second APN I created to be deleted... Anyone experience this?

thanks for the info! i ran across this thread while searching for a new ROM for my mytouch 4g slide, hoping it would fix the issue. once I arrived to the access point names, i noticed that the apn selected was for LTE. I switched to the regular one and now it works great. thanks!
I had this issue while on cm9 releases but it had gone away after I began using unofficial 10.1. Sort of. In certain areas- and I assume with certain towers - my data wouldn't work with some apps (ie., Facebook, Google maps) even though the data icon would show "H" or "3g" locked on and blue consistently. Sure enough, this fixed it right up.
Also, although my phone shows the option for the Tmobile lte APN in the settings, it was not selected by default. Thanks for this!

WiFi does not reconnect (Android Issue #58230)

EDIT BELOW:
Hey y'all, I recently got a Nexus 5 and I've been having issues with WiFi reception. I've read the other threads concerning the inability to connect, but I can easily connect to a wireless router the first time.
It's when I disconnect from one specific router and try to access another one that I run into issues. It simply hangs in Connecting, and then just reverts to Saved. The only way for the phone to connect to a router is for me to reboot it, in which case it does so quickly.
I was wondering if anyone had any insight into tackling this problem, or if it's an inherent software issue. This occurs both at home and at school, where I move from building to building (switch routers), but the login credentials are the same.
Thanks!
EDIT #2: I spoke to a Google rep a second time and they decided that since my factory reset did not fix the issue, they were sending me a replacement unit. I'll update this when I get the new unit and see if it still has the WiFi issue or not.
EDIT:So this issue seems to have garnered some attention in the 4.3 release of Android, and a handful of Nexus 5 owners have already reported the same issue (myself included)
https://code.google.com/p/android/issues/detail?id=58230
(Sorry, I can't post outside links because I'm a new user)
So if you have a similar problem, feel free to star and add your own comments.
I happened to have the same problem......not sure if this is a hardware problem or not.

Ah, I see. Well, I've narrowed the process to simply toggling the WiFi on and off, rather than having to reboot the phone. It's still occurring though.
If I manually disconnect and then reconnect to a router however, this problem doesn't seem to happen. It's only when I exit a router's range that I have to do a WiFi on and off cycle.
Sent from my Nexus 5 using xda app-developers app
Oh, and I notice that the perceived signal strength drops when I try to reconnect to my router. Again, toggling the WiFi on and off allows the Nexus 5 to immediately connect to the router.
I hope this is a software issue.

Hm..Toggling wifi on and off doesn't seem to work for me...It hangs in connecting for a few seconds and then goes back to saved... I still have to turn off/on the phone before it can connect to a different wifi hotspot..
I've got the same problem: switching wifi networks, from home to work and viceversa, my N5 doesn't connect. It needs a reboot.
Ciao.
I edited my original post with a link to the AOSP issue tracker concerning this problem. I also contacted Google concerning this and they just said to do a factory reset... To no avail.
Sent from my Nexus 5 using xda app-developers app
This evening, before entering home, I switch off WiFi, then I toogled airplane mode, I toogled WiFi on, and I got connection perfectly working.
Sent from my Nexus 5 using xda app-developers app
Interestingly, when first resetting the phone, I had to toggle Airplane mode in order to reconnect. However, eventually I can just toggle WiFi and it works fine. I'm not sure where the change occurred, unfortunately.
Hopefully my replacement phone doesn't exhibit this issue. Will update this, as mentioned in the initial post, when I get it. I still think it's a software problem, however, since folks that had 4.2 and updated to 4.3 suddenly experienced this issue.
So I'm starting to have this EXACT problem myself. I have a very strong signal for my home wifi and it's basically dropping to poor when I try to connect. After displaying Connecting/Saved several times, it still fails to work. I have tried rebooting it several times, toggling wifi and airplane mode, to no avail. Funny thing is, my work and home wifi have been working perfectly prior to this.
It wasn't until tonight that I started to have any problems. I moved some files through USB, just some stuff from my nexus 4, rebooted about 15 minutes later, and I couldn't get wifi after the reboot. Weird.
EDIT: I've tried a plain factory reset, didn't work. I ended up flashing the factory image, still didn't work. I'm not sure how WiFi just STOPPED working for me. Contemplating an RMA... I really hope someone comes up with something, seeing as I have a perfect screen and none of the other defects listed before.
This may be a fix!
Hey guys, so I've been keeping up with two AOSP issue trackers
https://code.google.com/p/android/issues/detail?id=58230
https://code.google.com/p/android/issues/detail?id=61945
And in the second link (Issue #61945), scroll down to post #9 Ryan, and he details what he's tried in terms of doing a factory reset WITHOUT having Google automatically restore data and settings. I've documented my results trying this, and it seems (at this early stage of my testing) rather promising.
Like Ryan said, it seems like it's restoring some WiFi settings that may not play well with 4.4 (and maybe even 4.3 for those exhibiting this issue as detailed in the first link (issue #58230))
So here's what I did so that Google would not restore the WiFi settings. Unfortunately, this does mean you may have to manually reinstall your apps and re-input your data by hand.
What I did:
1. Go to Backup & reset
2. UNCHECK "Back up my data" and "Automatic restore"
3. Perform Factory reset
4. After resetting and prompted to do so, input WiFi router credentials to connect to WiFi
5. Skipped logging into existing Google account
6. Skipped making a new Google account
7. After reaching Android homescreen, I manually added my existing Google account
I have a feeling that steps 5-7 are unnecessary, but I did that just to make sure it wouldn't try to restore any of the data.
It's been working so far, but I haven't been able to test it out much since I'm a school currently and it has blanket WiFi coverage (difficult to go out of range). However, I will add that the signal seems stronger than before, AND it's more difficult to lose WiFi signal now than before. Like, nearly impossible here.
Let me know how it goes for y'all. Hope this works.
Oh, and perhaps try
https://play.google.com/store/apps/details?id=com.brilliapps.wifiandmorefixer
before you do the factory reset. It may or may not work (one person said it did). I haven't tried it though, but if it works, it'll save you the trouble of having to do a factory reset.

I have also seen this on my device that I just received on the 15th. The wifi seems to drop out and re-connect after a while... But, my other, older android devices do not show this issue. After reviewing the previous post about NOT restoring from google.. and creating a fresh install.. I am beginning to suspect if that was the case. I was hoping that keeping it stock and not messing around with kernels and roms was one of the best features of a nexus device. I really hope google provides an update to fix this.
So just a quick update. I didn't restore from Google on my second device and the WiFi had been fine for close to a week now.
