Mobile network keeps turning off?

Sometimes when connected to 4G, I will lose data entirely. When I check wireless settings, the mobile network says turning on and won't do anything. A reboot fixes it but it is annoying.
Anyone else experience this?

yeah me too....actually I have no data at the moment.
*edit Ok now I've moved up to 1x...... WHOOOOOOOOO!

It's Verizon working on their network. People keep trying to troubleshoot it as a software problem, it's a network problem.

Same thing was happening to me all morning. I'm glad to see I am not the only one having this issue. As usual, Verizon Tech support said that there was no issues on their end.

Would that show the phone being unable to turn on the mobile network entirely? Seems weird but I guess I will wait a few days.

i had this too alot when running a froyo radio. i went to mr2.5 and haven't had the issue since.

I was about to ask if anyone was having any weirdness with 4G today... I tested my speeds using the speakeasy website and the upload speeds were fine (2.5-3Mbps) but the download speeds were incredibly slow, under 1 Mbps every time I tried. Guess it's issues with verizon testing the network.

4g fine in chicago 22mbps down, 4 mbps up, speedtest browser test.

the problem is the mobile hotspot software. just download the open garden wifi tether on the market

Yeah I'm having the same problem. I went to VZW and they are sending me a replacement phone. I usually run CM7 but that's an extra pain to get data back. Hopefully this problem is resolved soon.

Data has been sketchy at best in SLC today. It's getting a bit annoying to say the least.

Definitely big red doing work... CSR's aren't informed about that stuff, and yes, our 3g, 4g, and even 1x operate on a new section of the network.... If it persists use the modem settings @ ##778# edit mode, password 000000, turn revA on....

Same here, just started today and if that weren't enough, for me anyway, The International Data Triangle popped on and I have no voice coverage. I flashed back to stock and got the voice back but the data drops in and out. I wondered if there is some sort of outage. Called in and NADA that they are aware of.
Weird.. Might have to send this one back. This will be the second time. PRL and Profile Update fails.
In Minneapolis/St. Paul Btw.

That's my same situation everything exactly its wrks better wen u unroot but rooted sux signal wise I thought I was the only one having this issue I wonder is it just our phones or did da update have sumthn 2 do with it?

Not sure. When I called Sprint, they checked the tower strength, Known issues in the area and found nothing. So they want me to stop into a store and have them look at it. I put the standard recovery back on and locked it back up. Wish me luck.

Maybe you were watching the local action at Jennifer's and something in your pocket activated the PRL by mistake? Wink wink.

what radio are you running? try flashing ke5

Yeah, on ke5. They did manage to fix it at the store by erasing some network stuff and reinstalling the ota latest update with their computer. Then they said blah blah blah. I told them thanks a bunch. We will see.

Sorry for the highjack, Snoopy. Let's get your situation fixed.

Data drops

Okay, so my phone had been connecting to data and then just dropping within a minute and try to reconnect and so on, so I sent it into Samsung. It turns out, all they did was take the update that Samsung had put out while they had my phone and said it was fixed. It may have seemed fixed to them, but it is definitely not. It seems as though it only happens when I'm in a 3G only area which is where I live so I basically cannot use my data at all. I know it works when I leave where I live because I went to Los Angeles last month and my 4G and my 3G were working fine. I just don't understand it. I know it's not because my area has bad 3G coverage cause it's fine. I'm just so flustered. Any help?

Looks like tower problem to me since it works fine in town.
Flash every modem available to see if you can find one that works with your 3G tower. Have seen older radios that worked better with 3G due to the towers being old tech. Since the phone and radios are new may not be able to find radio that works consistently. The 4G will work with with any 4G tower. If not able to get 3G contact Verizon and put in a ticket on your local tower. Hope this makes sense.

All radios are on Rootzwiki. If radios don't work call them back. Nothing wrong with phone if works in town although also depends how far you are from tower. If any Verizon phone works you have a case for upgrade of tower or phone. If just at home may give you extender. Do not let them charge you for it.

I tried every radio. I think VRLEC was the best. It didn't stay connected but it seemed to reconnect faster than the others after it did disconnect. I guess that's something -_-

This device is solid on 4g and when in a 3g only area...soon as you get to a area where the data switches between 4g/3g/1x it becomes flaky at best no doubt. Beans rom seems to have the most stable data connection whem Im on the outskirts of a solid 4g signal...it is a device issue that should be fixed with a software update at some point. The problem is its easier for verizon to release a device with bugs, then to spend the extra time and cash to R&D and fix them before release date. I know it does not make sense, but think about it from there end. Lets say VZW has a device thats 90% bug free, so they release it to start locking people in on new contracts and rake in the money hoping folks dont complain about minor issues. If folks do comlain, well then vzw will run you thru the mill and send you a refurb, or open a claim ticket...by then after enough time has elapsed and no issue is fixed, they most likely will discontinue the device andoffer you a different one, passing the customer on to a whole new set of problems. Welcome to America, where its a dog eat dog world and we are all wearing milkbone undies.

Data drops

Hi guys,
Seems like I'm getting 4G data drops off T-Mobile. It connects for like, 7 seconds, then drops, then connects again. I've tried both radios and ROM's available (stock) and the same problem exists.
I'm going to return the phone as-is to the customer with the issue partly unresolved, mainly because it does connect voice and MMS, just the data has issues.
Any ideas before I give him the phone back?

Thank you for your reply! I will try that now.

There is a Zip that was created on the G2x forums that fixed the data drops on 4.0.4. O wonder if it would work for our phone given that it's a APN configuration. Hmmm...

Update: The creator of the APN fix confirmed that it should work on other T-Mobile phones. Has anyone tried it?
This is the link to the ROM, but obviously just scroll down and download the APN fix if you're having data drops and let us know how it goes:

Very poor DBm, asu and WiFi signal after JTAG service.

I just got my phone back from mobiletechvideos JTAG service. Since then, my phone struggles to hold WiFi and 3g. It very rarely pulls 4g. I have tried a factory reset. Also restored my IMEI backup just in case. I have an extra micro sim arriving today. I'm just wondering if I could be missing something simple or is my phone royally screwed?

Sounds like your radio.
They probably updated your baseband to MF1, I'd try to use mb1 firmware to see if that fixes your reception problem.

Thanks for the fast response! I flashed the MB1 firmware and still have poor signal. I'm starting to get depressed as this went from the best phone I've ever owned to the worst.

I did take the phone apart and found that the WiFi connection was loose. I corrected that. I started the phone back up and held the Sim card down in the slot while booting and the phone miraculously got 41asu.....for about 5 minutes and now its holding at a steady 2asu. So, would there definitely be something wrong with the Sim card? Or could the Sim port be going as well? Is there a way to test the Sim connectivity in the phone settings?

The lower the asu the better, in contrast to a higher dbm is a better signal.
2 asu is a pretty strong signal, you should be around -80 dbm.
Edit; Nevermind I mixed it up, a higher asu is better. I still think it's radio related though, but changing your sim card is an easy potential fix.

Well....sim card didn't work. Next I'm going to Odin back to pure stock and see if that helps. I'm starting to think it may be something in the NV items or hardware related. Hope I'm wrong though.

Hi David,
Often times when devices become bricked, it results in your NV items being damaged and causes this problem. Here is a guide that highlights this issue, and will tell you how to remedy the situation.
http://rootzwiki.com/topic/32397-tutorial-imei-backup-nv-with-qpst-us-variants/"
ugh. I really dont want to go messing around with the NV items if that is the case. Im in the process of flashing with ODIN now. I'll update if that works or not.

What is your IEM Showing?
If its been erased, then ODIN to stock firmware probably won;t fix that,
but, have you check your mobile network setting to see if you are on the correct network?
If you are with Verizon it should be set to CDMA, not GSM.

Software is not intermittent. Hardware can be. You may have a broken or loose antenna cable or connector inside the phone.
