3G Disappears

So my Inc has been acting up lately, I've got 3G when I turn the screen on, but as soon as something tries to use the internet (sync, browser, anything at all), my mobile network instantly drops, and when it reconnects, it goes and reconnects as 1X. I've tried going completely back to stock (the 2.1 rom), and it's doing it even there..... Anyone have any ideas?

wish I knew how to purposely do that since my 3g reception sucks yet yours is doing it on it's own

But I don't want it to. Reception in this area in general does suck, but even the places I ALWAYS get 3g aren't working.....

So I called and spoke to verizon. I have to bring my phone into the store, so they can inspect the damage to it, to see if I qualify for a replacement. If I don't, then I either have to buy a "certified replacement" or suffer with no 3g. They apparently think this is an exceptable situation. I'll be going to get the boost phone with unlimited calls/texts/web before I pay verizon 135 dollars a month to not even get unlimited. The Android phone isn't as good, but **** verizon, no way I'm buying a new phone because this one crapped out.

Can always find a used one online if it comes to that; DINC's aren't too expensive anymore.

When you say you tried going back to stock, do you mean the RUU? I'm pretty sure doing that brings you back to the stock radio, but I would double check that, and also make sure you don't have any apps that might mess with your data connection.

I had this exact problem last year. I ended up having to RUU and return it for a replacement because I was within the 1 year free replacement period. I returned it with S-OFF and got a new one that I've been using ever since.

I'm apparently still in the one year period. And yes, I did the FYI executive and without loading ANYTHING it won't stay on 3g. I'm talking bare phone, no apps, no accounts. It did work slightly better though. I won't be going to Verizon until tomorrow, so I will try a few of the newer radios I guess. I've always been partial to 7.28.

If you go to CM7 you can actually switch to just 3g I'm pretty sure. I know there's an add-on for JuiceDefender that does something about 2g/3g for aosp roms.....

I have the same issue! Went to bed on Thursday working fine, woke up Friday morning and was having this issue! I tried everything but restore the stock. I updated the radio, did a complete wipe and flash virtuous 3.2 rom as well as ##778 and modifying my settings to find a different tower to use. The tower modification seemed to help a bit, but in certain areas!!
Verizon tech said the same thing that I should take it to a store and have them check it. I do have insurance on it, so it won't be bad paying 50 and getting another one. But my concern is that I won't be getting the AMOLED screen. I had my phone pre-ordered and love it. Not even a scratch on it because I had it protected since I got it.
Where do you live?

My problem was actually fixed. I tried the RUU a few times. What fixed it was going into HBoot and doing a factory restore. It made me deactivated my phone after booting up, but my phone has 3g again. I tried updating prl before that with no luck. So try that, see if it helps.

I actually just returned to 7.28, after using the newest Inc Gingerbread Radio, and got stuck on 1X as well. A simple toggling of Airplane mode On and Off fixed it for me.

This happened to me just a few days ago. Mine happened because I did a *228 on my Inc running an Evo rom. I did the RUU fix posted in this forum and it worked.

Still having data problems. No 3g/4g!!

This is really becoming frustrating. I switched to Verizon a week ago and had 3g/4g service for a couple days and now NOTHING. I called support (12/23/11) and after an hour on the phone, visited the store. Then after 2 hours at the store where they switched over the SIM card, gave me a brand new phone, and still having problems with the phone. So I had to open a trouble ticket to look in to my problems with my data connection on my Galaxy Nexus. According to the store, support said I am the first to call about the problem.
Store rep was on a 4g HTC phone...his data was fine. My mom is on a LG 3g phone, her data is fine. All in the same areas of town as well. Why isnt mine? Tried CDMA only and nothing as well. For about 10 minutes, I had a 1x data connection that was slow but it worked. No nothing, again.
If I got a new phone, new SIM....then the problem is with Verizon somewhere and needs to be fixed. I am paying money for something I do not have and its a waste. I understand there will be problems from time to time, but don't release comments saying the problems are fixed when there are clearly still issues.
Anyone else still experiencing data issues specifically with the Galaxy Nexus?

Was a nationwide outtage Verizon said was resolved a couple days ago. Was working fine on Monday/Tuesday. This isnt related to the fix to resolve the reception problems. I can text and make calls just fine.

Try disabing vzw backup amd google +. Stopped my phone from doing exactly what you describe.

I've been having the issue where the hand-off from wireless to 3g tends to cause me to have no data connection at all (wifi shows up, but can't 'do' anything like browse to a website and such, and 3g never makes a 'connection', but I know I'm in an area where I should have plenty). A simple restart of the phone fixed the problem, but in the long term, I shouldn't need to do this in order to get a data connection. Just my experience.

I had the exact same problems. I returned it & reactivated my Thunderbolt. I hope Verizon actually fixes the radio instead of just changing the number of bars that get displayed. My lack of faith in this is why I returned it before my 14 days ended. I hope they will actually fix it & I'l try again in a few weeks. You might consider the same strategy.
Also, I had bad data & signal before Google+ was even on my phone.

Everyone isn't having problems. Verizon's fix is just going to change how the bars are shown.

I kinda doubt they are going to keep swapping out my phone over and over again until I find a working one. My original phone worked fine fora few days and probably is still messed up from the recent nation wide outages they had. They were hesitant on replacing my phone the first time.
Going to call support in a little while and follow up on my trouble ticket I logged yesterday. They better have a solution for me.

You paid $XXX for this device and you're afraid they aren't going to give you a new one because this one is defective? This issue may seem widespread because of all the complaints on this forum, but trust me, not everyone is having issues. Check my other thread.
Verizon already came out and said there isn't a performance issue with the device and their patch is just going to change the bars. So it's now or never.

Are people having slower 3G speeds on their CDMA devices? This is my issue as well. My sister's iPhone is consistently getting 1mbps> whereas I'm only getting ~100kbps down. Upload is worse at 47kbps.

I already got one new phone replacement yesterday. Going to call support yet again here in an hour or so and see if they have an update on my trouble ticket. But I would think it if was a defect in the phone, that this issue would be well known by now and posted everywhere on the internet. I understand what you are saying....just hope they get it fixed.

I'm having this problem too. I'll be on wifi at home, both wifi and cell bars will be blue. Everything is dandy. Then when I leave and turn off wifi the 3G icon appears and I have a few bars, but they are grey and websites don't work. I thought blue/grey just meant you are/are not logged in to google services, not whether or not you have data connected in general. A restart solves the problem, but it shouldn't come to that. This was a problem before the outage as when they were setting up the phone on release day in the store it took awhile to connect to 3G. Is this also why when I switch in to airplane mode I can't come out of it without a restart?

[Q] Lumia 900 Spotty Data Connectivity?

I occasionally will lose data connectivity out of no where. Half the time it happens after a soft reset. The 4G/LTE icon is still on the screen when this happens (mostly with full reception bars), and I still have access to voice.
The only "fix" I've encountered is turning airplane mode off/on three times, then powering the device off/on, repeating this process at least 3-4 times.
My sim card is provisioned correctly (obviously it works since I've had data before).
Was just wondering if anyone else is experiencing this.

wow, of all the reviews, all the conversations with owners and testers, you are the first to mention this. Are you in an lte area? I know a higher concentration of drops appear to occur on lte areas
We'll all have to watch this one.

I think you have a bad phone. You will likely need a new phone to fix this. I know becuase this is what my 1st Droid Razr did. Does the phone get hot when this happens? does it seem slow as crap data speeds, like you can't even get a 360p youtube to load and web pages take forever. when this was happening my H+ S2 would make my RAZR look like it was on poor 3g/good 2g.
My isuse it some times droped EVERY thing or some times all data, but voice worked. A few times I fell back to 1x ( verizons 2G) and a lot of times 3g. (good day there 3g SUCKS and if any one tells you diffent take a 50 cal and .... ok you get it.)
Any way hope it gets fixed.

WPCentral has a review out (http://www.wpcentral.com/wpcentral-review-att-nokia-lumia-900) and noted the same thing. Possibly a bug: "We have seen an odd occurrence where our Wi-Fi connection can receive data but outgoing data crawls. We’re not sure why that is but haven’t seen it before on our other Windows Phones which causes us to raise an eyebrow. We’ve also had a few reports from early users noting the same behavior. Toggling the Wi-Fi on/off for a few minutes seems to do the trick but we’re a little concerned that this may an early bug."

Whats interesting is that users (like myself) who have moded their phones to re-enable the internet sharing option on devices that originally had it disabled - encounter the same issue. Leads me to believe that it could be a bug in the OS itself relating to internet sharing.

WiFi issues

I have the latest Nokia software. I can connect to WiFi sources however I loose data connection but the signal shows strong.
Could this be a hardware problem?
Sent from my Lumia 900 using Board Express

when your phone is not charging, and the cellular is not turned off the phone will lose the wifi connection. This is a windows phone problem, not nokias problem. ONce the phone goes to standby it will loose connection, only if your phone is charging and the data is turned off is that the wifi will stay active.

Well this happening while browsing or playing games. The signal never drops, however turning WiFi off then back on resolves this issue.
Sent from my Lumia 900 using Board Express

Just for clarification, having Data on/off has nothing to do with Wi-Fi. Wi-Fi will remain on when plugged in to a power source, or while streaming/downloading something. Otherwise I will turn off about 30 seconds after the screen he's to sleep. Same whether Data is on or off.
Why the OP is losing the Wi-Fi connection is a mystery though. Are you connected as a guest where the connection times out after a period of time.
Sent from my Lumia 900 using Board Express Pro

Not sure what you mean connected as a guest. Just seems I loose connection and get an error in the apps saying they have disconnected and or no data connection. This just happened on a free ATT hotspot at a McDonald's.
I am thinking I will need to exchange this phone. Just sucks to have to do that. If it is software I guess I could wait for an update bit no one else seems to have this issue.
Sent from my Lumia 900 using Board Express

So is the problem occurring on all Wi-Fi connections, or only public connections like McDonald's? They may have a timeout. For home, Linksys routers have a guest connection that will time out after a period of time and require you to reenter the security key to get back on the network.
Seems unusual that you may be the only one with this issue.
Sent from my Lumia 900 using Board Express Pro

This is only happening on WiFi at multiple spots. The signal always shows strong however it just wont pull data until I restart the wifi. The games or IE will just come up and say there is now data connection.
I was hoping this might be a software bug but I am thinking it is a hardware issue. I have 20 days with ATT to do an exchange at store level so when I get back to Chicago I will do that. If by chance we get a software update before that time I will do that to see if there is a fix for this issue.
It does seem I am the only one with this issue. I was at a friends house that had wifi and he has the same phone. I couldn't stay connected while he was.

I had the issues with my lumia too. But after doing a reset it never appeared again.
Sent from my Lumia 900 using Board Express

Correct. This sounds like it could be the tethering bug. It you try to initiate tethering on your phone, with or without an AT&T tethering plan, it changes a setting on your phone that will cause WiFi to disconnect. Only a hard reset will correct it.
I have been tempted, but have so far not clicked the tethering option.

I'm not positive this is true. Before I had tethering enabled, I did turn it on, to see what it did....remember when the lumia came out everyone thought tethering was included. It did not impact my WIFI, or anything else. Though I do reset my phone often, I did not have to after activating tethering.

It was so bad that I got fed up and went to a local AT&T store where they saw it first hand. I went through the grueling process of about 3 hours of my time to get a replacement.
I have yet to turn the new replacement phone on that I received from AT&T. The main reason is because the backup/restore doesn't work across different phones--only the same phone that the backup came from.
I'd say this phone has a very nasty wifi bug somewhere.

I have not tried opening Internet Sharing on my L900, but have read enough posts from users who have and subsequently had the WiFi issue described above. So is it true, not sure. But a hard reset might save the trouble of exchanging the phone.

Some phones are actually different firmware-wise. Launch phones had a different color dot inside the sim tray. The replacement I have has another color and different firmware version (but same OS version). So, all phones were not the same launch and post-launch. I was even asked what color the dot was by the AT&T tech before replacement.
If you weren't having the same problem, you likely had a different set of circumstances to work on.

I am having this problem exactly as described in the other thread. These are the only two places I can find online about this issue. Everywhere else is complaints about wifi going off when the phone sleeps. I will be in the middle of browsing and I think a web page is taking extra long to load while i'm staring at the white screen like an idiot. I'm glad you were able to duplicate the issue at the store.

V35 + Cricket = no paid hotspot. WTF? help...

For years I have used a Leeco with a custom ROM as a hotspot for the Android head unit in my car. Last month, I got a warning about hotspot use and decided to go legit. The hotspot data got funky after the warning.
->I bought an LG V35 direct from Cricket, carrier unlocked
->I upgraded 5 family lines to the "Cricket More" plan that includes 15GB of hotspot data
But Cricket blocks all except a short list of phones from hotspot use even with a paid plan. I spent about an hour on the phone and they basically offered me nothing except to return the phone. No BYOD phones will work as a hotspot either except for iPhones.
What can I do? Has anyone else run into this? The custom ROM Leeco basically didn't work after the warning. Is anyone successfully using a V35 with a custom ROM as a hotspot?
Thanks for any help.
10/6/2019 Resolution for anyone else with a similar Problem:
1. it is difficult/impossible to bootloader unlock and root a LG V35. But that's not apparently the issue here.
2. Cricket only supports wifi hotspot on a short list of phones and all else including BYOD rooted/custom ROM devices are throttled to the point of uselessness even with a paid hotspot plan.
3. PDAnet works well but didn't work for my Android car headunit even after every known update.
4. I am using EasyConnect, a point-to-point screen mirroring app over USB, on the head unit and its OK. Not great but good enough to not trash Cricket and look for a new carrier.
Thanks!

Since no one else has responded, I'll make an attempt. You are going down a lot of paths without gathering any info in advance. The v35 cannot be bootloader unlocked without specialized tools. Even if you bootloader unlock, there is limited developer support. TWRP has not been ported to the v35 and there are no custom roms. Hopefully this situation will change, but the prospects are dimming as time goes by.
You still MIGHT be able to get hotspot working. I say might because I am not familiar with Cricket. Many carrier's phones check for a tethering subscription before allowing the hotspot to be turned on. The rom on the phone communicates with the carrier to make the check. That MAY be the issue you are facing since Cricket is an arm of AT&T. If so, you can get around it by cross-flashing to the open market / Google Fi rom which won't do a subscription check. I did that with my AT&T branded v35. It works great on StraightTalk. Browse around in the threads in the v35 forums and you will find information about how to cross-flash.
Now back to the MIGHT part. Some carriers, Verizon for example, can detect tethering. They throttle hotspot speeds for Unlimited plans. Presumably they could just block hotspot traffic. I have tried everything to get around throttling to no avail.

I might be able to help here. I have a rooted essential phone on the unlimited data + hotspot Cricket plan. I am able to activate hotspot but it is severely throttled (128k by the looks of it). No fixes, not even fixes that use root, has changed this.
The only thing I have gotten to work is pdanet app ($8 in playstore, after 30 days). With it I am able to connect my laptop/tablets to my data plan, all while hiding the usage from Cricket. I am not sure if this will work with your head unit or if it's viable since you kind of got to jump through some hoops to get the stuff working but just thought I would chime in here.

Thanks, there seems to be 2 things going on. 1st is the tether provisioning check. One can turn the provisioning check off (most custom ROMs have done this and it was what I did with my Leeco); or you can pay the carrier. For my v35 I paid the carrier and it still didn't work since there is some 2nd network check that isn't visible to me.. What runderekrun describes is exactly what happened to me.

Thanks, that is helpful. For me, I went years with no trouble and then got a warning text followed by the throttling. It was very, very slow.
I just tried PDAnet+ and it worked! Hurray! seems to need the app to act as a passthrough but I can live with that. I have not tried it on the head unit yet but it's fundamentally just a big Android tablet and PDAnet just worked on my tablet that is actually a tablet. Thanks!

PDAnet+ worked my S3 tablet and Windows laptop. But did *not* operate for my Android head unit. Any tips for figuring it out?
