[Q] Cellular Data issue

Hey Guys -
I had the Moonlight WP7 ROM on my HD2 working pretty well, thought i'd flash LEO71 on my phone to play with some new features and when I did, the Cellular Data portion failed to work.
I can't sync email, etc. Wifi works great and I can make calls.
I tried flashing back, but it seems (i can't quite tell - maybe someone can show me how to tell the version) that either it isn't reverting back to the old version or even if I'm back on Moonlight the cell data isn't working.
I did a quick search and didn't come up with a fix on this issue.
Could someone point me to a thread if there is one, or has anyone ran into this?
Thanks!!

So after a number of reboots, it seemed to start working...
...but now after a few minutes i get the error "Invalid SIM". A reboot fixes it.
Any thoughts?

Market stuck "Downloading"

Hi, I just got a brand new Xperia Play and am loving it so far, aside from one infuriating issue.
When I'm on WIFI I simply cannot download anything from the market, I've been messing with this for the past 2 hours, things I've tried:
Clearing app cache of several apps related to downloading
Toggling WIFI / 3G
Restarting phone
Updating to latest firmware
Reset to factory settings
Play with router wireless settings
Reinstall router firmware
The only thing that did something is clearing the cache of the download manager, after I did that I was able to install one thing from the market. But it only worked once, it's not working anymore.
I'm also unable to play youtube video's when using wifi.
Does anyone have any ideas as to why this is happening? My phone is brand new, so it can't be something I did with it.
Also, up till today I had an HTC Magic, which did not have the problem on the same wireless network. It did have occasional "download starting" hiccups, but nothing like this.
Any advice?
Thanks!

Edit2: False alarm, still not working.. seems to come and go

You have the weirdest problem.. Did you check your router to see if it's generating enough ip addresses for all your wireless devices?
What is the distance between you and your router and what kind of router is it? I believe the play has a weaker wifi radio, so it might be dcing too often to stream and download.. Try standing closer to the router to see if there is a difference first.

I'm right next to the router and the web interface shows a full signal, so it can't be that. I can also see in the web interface that an ip address was assigned.
I've tried setting the phone as the DMZ and disabling the router firewall. No luck with that either.
I also tried upgrading my router firmware from Tomato to DD-WRT and doing a factory reset, but again .. no luck.
I'm running out of ideas, it seems the problem originates from Android and not my router, but I can't think of anything else I could try. Could it be an issue with the Android network in my location?

Omfg.. 3/4 hours later I finally got it, and this one wasn't suggested anywhere else so hopefully this will help some others in the future.
I had to go into wireless settings on my phone, click menu, go to advanced and then manually configure the network connection. Make sure your router has reserved an ip for you and use that one, otherwise you might end up trying to use one that is already in use.
After that it all seems to be working for me (so far). Fingers crossed that it won't stop working again.

Yea you couldn't find the answer anywhere else because it seemed like it was an isolated incident. Gratz for figuring it out though.

Next day, working fine in the morning. Couple hours later and it's back to getting stuck on "Downloading". Tried toggling static ip with no luck.
God this is incredibly annoying. I'm guessing it'll magically start working again at some point, and then stop working again later.
From what I've found through google this bug has been around since the very first version and not a single solution has been offered by google. Seriously this is ridiculous

Hi,
I'm having exactly the same issues.... Normal browsing, etc works fine on WIFI but market just wont work on WIFI.
I dont even see the device hitting my router when I try to download thru the market. Other network connections are seen by my router.
I wonder if it might be linked to the the fact that I'm running a UK rom on my device. When I'm using my data connection off Rogers, it actually does a RMNET to the British government... So we are seen as downloading from the UK.. Just an idea...
It's annoying as hell....

I was going to say download speedtest.net app when you can and see what it yields... but I see you've got it figured out. Nice!

Interesting, so you're saying that google somehow classifies us as UK users, which causes problems when switching to WIFI, which is not classified as a UK connection?
It would make sense, seeing as it seems to start working again after a while.. which could mean that whatever info google is caching on us is expired and it finally adopts the WIFI connection info.
Still, I have doubts about that.. I mean wouldn't a LOT more Rogers users be complaining about this?

The only persons that would be complaining are people like us running UK roms but our WIFI is coming from a canadian provider. In my case Videotron.
So when i<m using 3g data, i'm seen as coming from the UK because of the RMNET connection and when using WIFI i'm seen as Canadian... with a uk rom.
I've read that the market DOES have regions... might not be 100% correct on that but it might be part of my issue.
Mine BTW, never works anymore even after clearing cache, FC the market, etc...

lol i got the opposite problem i have trouble downloading stuff from the market using 3g but works perfect using wifi
not really an issue since im not an app whore

Its not a issue on play all phones has that. Simply log in to your Talk app then try again. (launch Gtalk app and login)

Thanks, but i had already tried that.
Reinstalled the UK rom yesterday, and even after a clean install market still doesnt work on WIFI even tho my WIFI works for browsing, accessing my computer thru RDP, etc.

This only works for some people.
My market has been working for a day now (I didn't do anything to fix it), I'm expecting it to stop working any moment. Fingers crossed.
Edit: Aaand there we go.. stopped working again. Sigh.

Got the same issue both on my Nexus S (Videotron) and (which is strange), on My Motorola Xoom Tablet which only has wifi, no 3g !!
Edit: If I connect my tablet thru my cell phone (wifi tethering) I have no problem with market

ok so me and mobidoy are both on Videotron...
Naatan I see you are in quebec... Videotron also?
Starting to believe it migh be an issue with them

hey
im in videotron too and since 4 days i cant watch youtube on youtube app and my download on market stay stuck in green bar!! i have a toshiba thrive android 3.1!!!!!
when i connect with a 3g router or on the wi fi in my city everything work again
so it clear that videotron is the problem!!!!

Had the same problems
First time hard reset fixed it.
Second time by magic, sorry. I was about to send the phone to repairs
I used the XDA App to post this, what did you use?

I've been having the exact same problem as you and can't seem to find a way to solve this. I just purchased a Galaxy Tab 10.1, WIFI only, and at home nothing will download from the Android market. It just gets stuck. Youtube videos also dont work via the app.I tried it out at a friends and everything worked flawlessly.
At home, I also have Videotron internet. I just called them, and tried to explain to their customer service but obviously they were quick to blame it on anything else they could. They said they did not block any ports either.
I read a thread about some vodafone users in the UK having a similar problem than us:
Edit: It wont let me post an external link because I'm a new user, but the post is on androidforums.com and is titled "ANDROID MARKET download/update problem via WiFi"
It seems their problem was fixed after calling Vodafone.
I'm also inclined to point fingers at Videotron since its odd we are all customers of theirs.

Just called Videotron technical support, they have an open ticket about it since yesterday morning and are actualy working on the issue !! There is hope !!

Upgraded 4G Xoom LTE Connectivity Issues

Greetings All,
Got my Xoom back from its 4G upgrade last week and I have been noticing some issues with connecting over the 3G/4G network now. I use pocketcloud to connect to computers over RDP and when connected over WiFi networks, it works fine (computers connected to networks other than one I am connected to WiFi on), but when using the 3G or 4G connection on the Xoom, there is a network connection error. I tried it out on my incredible and it works just fine. Also, sometimes I get an error "cannot update" from the engadget app.
Also, the new market would not install some of my apps, like ThinkFree Office for example, I worked around it by using the web interface of Android Market on my computer and it worked fine.
I sent in the Xoom completely reverted back to stock 3.1, I recieved it with 3.2.2 stock. I cleared memory after I got it back and did a factory data reset. Not rooted, and no other modifications have been made.
I'm at a loss as to why some connections are causing the network to flake out.
Regards.

I read on here that some of the app installation issues were due to the possible change in pixel density that took place with the upgrade but that is something you can change back if you root.

I'm noticing the same exact issue and have no idea what is causing it - let's see if together we can figure it out. It's extremely flaky so far.

I got my upgraded Xoom back today and noticed the exact same issue. It wouldn't activate on the setup screen and prompted me to reboot. After reboot, it connected to 4g just fine and showed the 4g icon below.
I then went into the market to install my apps. It installed Thumbkeyboard just fine but when I went to install others, it stopped at 8.03k on the download. Did this for every app i tried.
I turned on wifi, connected to my AP and the downloads worked just fine. Even tried a couple reboots before doing this and it didnt work.
My 4g signal is about 75% so it's strong.
Very strange...

Power off
Remove SIM.
Put SIM back in
Power on
Done. Worked for me.

I take it back, still having all kind of issues.

just got mine back this morning, and it wont connect to anything! no 3g, no 4g, no wifi... nothing. WTF!?!?! restarted, pulled sim, etc...
going to do restore next and see what that does.

Same connection problems
Got my LTE upgrade back.
When I am at work I cannot update Touchdown from inside the firewall (not sure why) so I flip back to Verizon to refresh by shutting down the wifi. When I do, I noticed that the xoom would drop the connection (three bars) and then not reconnect. When I try to turn on the wifi it stays grayed out and neither system will connect until I reboot.
Went around with VZW tech support, they reported that the unit was registering on their network but not connecting. Sent back to Moto for further testing, got the unit back (they reported it was a software fix, no other data) but the unit continues to have the problem.
Stock 3.2.2 xoom with LTE
Any suggestions appreciated....

Has anyone been able to resolve this issue?
Hello, I am still having all kinds of connection issues after I received my device from Motorola. After a reboot the xoom will connect to the Verizon network but If it stays idle for some time, I lose the connection and it will not connect until I reboot the device.

sent it for replacement
I had the same problem. I had to send it back once for 'repair' (no improvement) before Motorola replaced the unit due to an undefined hardware problem. Keep calling or go to a store.

I had something similar when I got my Xoom back. Apparently the geniuses at Verizon never added the SIM to my account. Took multiple calls/emails to get it corrected. Once someone realized it was missing it was corrected in about 10 minutes.

In your case did you have sporadic connection or, without the SIM number, were you completely unable to connect?
BTW, I missed this thread when it was fresh (as I was traveling) but I've had the exact same issues since the LTE upgrade. When it happens, the only way to reconnect is to reboot.

I used to be able to get it to reconnect by switching airplane mode on and off. Sometimes I had to reboot. Friday, even that did not help. I was furious. The next day, the update pushed out to me via wifi. I guess the servers recognized me as a customer again even though I already had a 2 year contract. Some people got the dataplan because they don't use wifi. I love the shortsightedness of the people who come up with this... not.
At least I haven't gotten disconnected since the patch was installed.

I had to unroot my device for 4G to start working normal.

[Q] Losing data connection when switching between Wi-Fi and Cellular Data

Hi All,
Long time follower, first time poster..
I have a very annoying issue with my Nexus 4(4.2.1 and rooted on Tmob).
I use wi-fi connection at home and work and in-between I switch to HSPA or should I say, I was able to..
Lately I have been seeing that If I leave the Wi-Fi area, the phone doesn't switch to cellular data and the connection gets lost.
Switching to airplane mode and back brings it back most of the time but it's really annoying having to do so..
I did find an issue #40514 on the google android code page( code.google.com/p/android/issues/detail?id=40514)
Tried the suggested work arounds like "Auto Network" setting and it didn't seem to help..also have tmob in the APN settings. Still the only thing that works for me is toggling the airplane mode.
This happened to me once on my previous Gnex but with N4, it started to happen all the time.
Does anyone have a better solution to this issue?
Thanks
Oz

even I face the same issue with this new Paranoid 4.1.2 ROM for Atrix 2. I've noticed only one ROM gave me consistent data 24/7, it was from same dev altered his NUMA B2.
But other than that, this has been a repeating problem in all ROMS. Data stays on for hours without issue but suddenly drops and never comes up, other than air plane toggle. Somebody mentioned it is with the network and trust me it is not..
but I'm also eagerly waiting for a solution

Yea, at first I thought it has something to do with rooting but apparently it is happening with non-rooted phones as well..Google needs to address this issue..

Are google aware of this wireless connectivity issue? I've posted and started another thread which details a 3G data issue... :/

Just throwing in my two cents; I starred the threads that I *think* are related on the google tracker. My experience is like this:
I start up Sirius on my phone before leaving home (On wifi)
Driving to the end of my development and then lose WIFI which in turn turns my 3g/4g gray for about a half mile
Picks 3g/4g back up eventually
As I'm driving to work if I end up picking up any open WIFI spots that have a login, once that happens I lose 3g/4g again then have to either wait till that access point is out of range or just turn off my WIFI before data will pick up again
It's pretty annoying; probably going to have to create a tasker profile to turn off wifi when leaving the house and back on when I get home.

Same problem on an LG F6 Optimus
I just got a brand new LG Optimus F6 and I'm noticing this same issue. The phone is stock and runs 4.1.2
Anyone found a solution?

the issue continue in n4 with 4.4?

x below lte signal and not internet connection help!

Hello so as stated above for some reason i have an x below my signal bar but it still says lte but not connection, ive tried the following, remove sim and put it back in (both with the phone off and on), checked my apns which i never had to mess with before (which i didnt have this issue yesterday just saw it when i got to work which i usually have lte signal), turn on and off airplane mode, turn off and on mobile data, ive tried every fix i could think of so far with none of them working.. my cell service is been paid and i checked my straight talk account to make sure, but now comes the weird part when im connected to wifi and pull down the quick toggles it shows no x under the lte (see screenshot below) does anyone know how to fix this issue i rely on my lte data for directions and gps at work.
Phone info:
Android 8.1 beta opp5 rooted
Thanks to anyone that can help!

I am having this same issue as of this morning, and I am on the Straighttalk AT&T network. I wonder if they just updated their APN network and our APN settings need to be updated too? If so, I'm not sure what settings to use.. using the straight talk website and selecting "Android 4.0" (the newest version listed), it shows the settings I'm currently using. Anyone else having/resolved this issue?

Borrow a (different carrier) SIM from a friend to see if it is a network issue. If the LTE works on that SIM, go to ST and have them provision another SIM for you (free). If the LTE still doesn't work, back your phone up, wipe it, flash a full image.

I called STW tech support, and they told me I had the wrong APN... I updated my APN settings (but really it was nothing other than changing the ID, so I don't think it had any real effect) and still had no data. After checking downdetector.com, it appears there is a widescale data outage with straight talk (or more specifically, AT&T). One of the commenters stated the following:
"I can confirm the issue is DNS. If you have the ability to changes the DNS on your phone, you can restore service. If you have Android + Root, I used DNS Override successfully. Just set DNS Servers to Google's"
I just used DNS Override ($2 app) to set my DNS servers to Google's and that resolved my issue. Hope that helps. If you don't want to spend $2, there are some free apps that also will change the DNS servers for you, and there are other methods detailed here: https://forum.xda-developers.com/ge...ide-how-to-change-dns-android-device-t3273769

Update: earlier that day ot seemed to resolve itself while i was driving at work amd got to my destination which was about an hour away and once i looked at my phone ot no longer had the x and had full service amd working lte so idk maybe it was cell tower maintenence but don't know for sure but the issue hasn't happened again tho but thanks for everyone for the help and suggestion!
