4G connection drops out often. Won't come back for a while

I've been having an annoying problem lately. I'm running theory of ginger 4.2 and lately my 4G connection will just drop out and it won't reconnect for 5+ minutes. If I manually disable and reenable the connection it immediately grabs 4G back. It will stay steady for maybe 40 minutes and then drop out. This has happened on the MR2 and MR2.5 radios. Suggestions?

Mine does this routinely on a stock phone. Dunno if it's the network or the phone.
Dont know if this phone/network was ready for primetime

Mine just started doing this a few days ago.

So I flashed to CM7 on a froyo radio and I'm still having connection issues. How hard is it to get a replacement sim card? I think that might be the culprit honestly.

just call Verizon or go to a store.

Should I take cm7 off or just don't show them my phone.

i doubt it's the sim cards doing this... it's for sure the radio's. the mr1 radio on froyo drops my 3g to 1x alot, so did mr2 but mr2.5 was perfect for me. i just want a functional radio to ship this week.

It just started a few days ago, and a friend of mine with the thunderbolt isn't having the issues I'm having.

Mine started doing that last week while on Gingeritis final. I flashed all kinds of roms & radios (including Froyo) with no improvement. I even went to verizon & swapped sim cards, and still no better. I went back to bone stock and finally got reliable 4G again. Very frustrating

I've been having this issue for a couple of weeks at home but at work the LTE connection is rock solid. I think it's the network where I'm at. I went back to an old Froyo build and radio set and it was the same issue. I've tried every radio combo both GB and Froyo ROM's and it behaves the same way. At work no issue...at home I have to switch to wifi. It'll show LTE with bars (sometimes full 4...usually 3) and I will have activity on the up/down arrows and it'll work for a minute and then stop working until finally the LTE icon goes away and it goes to 1x (or even sometimes 3G and I'm in LTE mode.)

Its looking more and more like a network problem. Might as well save myself a trip to the Verizon store. Oh well, not that big of a deal I guess. Stand in line for 40 minutes for them to tell me they can't help.

Mine does this but I'm on the edge of the 4G signal where I live. I just lock in 3G and don't worry about it. When I get in an area I need to use some speed I turn 4G back on.

Northeast Ohio Connectivity Issues

My Blunderbolt has not been connected to the 3G network all day. I live in the Youngstown area. Has anyone else been having this issue? I thought it was me and that I had caused a problem by flashing a new rom to it, but it sounds as though others are having issues too.
Let me know and if there's any fix that I can do myself, let me know that too.

Same here north of u in Ashtabula... No 3g. My daughter has an iPhone and she is fine.

I am in east Texas and I noticed problems today as well. I could not get a 3G connection until I did the ##778# trick and turned on rev.A, so possibly there is an issue with eHRPD like what happened right after the TB came out?
I am on BAMF 1.0.9 and have been since it was released, so it's not a ROM issue for me.

Good one! Actually I live in Austintown so .
I'm running the new eternity rom from virus with the most recent radio.
I just did the rev. A trick and now it works again. Yaaaaaay.

Same problem in Akron on an doff Monday evening and in Ravenna Tuesday afternoon. I did pick up a spot of 4g on 76 west just around 14. I typically loose or regain 4g between brimfield and Tallamadge exits. Maybe Verizon is upgrading.

Clearly an issue with authenticating to Verizon 3G eHRPD and 4G LTE network. If you were previously successfully authenticated and the lifetime timer hasn't expired which would otherwises force a reauthentication or you haven't toggled airplane mode then you probably still have data. If you've completely lost data you can at least restore 3G EVDO since it uses a different authentication method that still works by doing ##778#.

It's been 3g, 4g and out completely sense 2pm here in Kettering.

Skyrocket on straight talk .

Anyone getting slow speeds like 0.15 mbps on hspa i can't get connect to hspa+.

Well, give some details... I just switched over to Straight talk and I have had no problem.
Did you just barely switch to straight talk?
What have you done to fix it?
Do you have the right settings?
Do you have the 4G icon up to?
Share some deets and maybe someone might have an answer for ya.

4G doesnt always mean 4G on the skyrocket. It can as easily actually mean 3G. But still should be better than .15. Thats 2G speed.

This is a question and should be posted in Q&A. On a side note please provide more information when asking something and keep in mind network speeds are specific by modem/region/provider(if it applies) so I doubt (based on on the little info) you will get a helpful answer.
Cheers

Well my max speed is o.15mbps in Seattle area i haven't reach anything higher than 0.15 and im also on sky ics 42f ucle2 modem . Now it connected to 3g than h symbol but still slow speeds. My iphone 4s gets 8 to 13 mbps on straight talk.

How much data are you going through? Straight talk is starting to throttle. Some people speculate that the speeds are slowing down to a lot of traffic also.

just switch sims withyour 4s. If your skyrocket gets good speeds with the other sim then your throttled.

Ok before you go off and sell it try a few things. First make sure your preferred network mode is set to GSM/HSPA and not Auto, i had some issues with data on auto.
next double check your APN Settings
they should look like this:
If you notice i do have PAP authentication turned on, it seems to help with me reciving MMS's in my area, and it only affects ICS roms, gingerbread i have to leave it off. My fiancee's captivate i had to turn it on to get the MMS to work as well.

weird switching between Edge and 4G

Where I work, there is generally only edge network speeds (AT&T). In my building though, we have cell repeaters. While getting close to the repeaters, I can put my skyrocket into airplane mode and then re-enable the radios and suddenly, I'll get 4G (albeit slow 4G ~ 800kb/s-1.1 Mb/s) speeds.
1. Why wouldn't the phone auto-switch to the better network
2. Why can I get 4G through the repeater, when outside my building I can only get Edge? Seems more plausible that the repeater would cause even more loss on the network throughput...
just curious to see what others think about this.

The repeater is powered with a much better antenna than your cell. So it can pick up the 4g signal where your phone can't. It then sends that signal to you. So it doesn't surprise me that you get 4g service around it when you normally wouldn't without it. What does surprise me is why your phone doesn't automatically pick that up. Dunno

even weirder was that until I updated to ICS recently, I couldn't even get the 4G, while everyone with Iphones could switch into airplane mode and back and get 3G at least. odd.

yeah, it's not "real" 4G for sure. I'm only getting a max of 1Mb/s down. Usually around 400-500kb/s. but definitely beats out 15kb/s that I WAS getting
The phone indicates it as 4G on the icon.

Persistent Data Connection Problem

So, it's been more than a month now since I have not been able to get a solid 3G connection in my area where there is no 4G. Last time I asked no one was really able to help, so I thought I try again. If I turn on my data, it usually takes a while for it to connect and once it does, it stays connected for about 30 seconds to a minute. Sometimes it's longer, but it always drops eventually. Sometimes it has the 3G icon, but nothing happens still. It's a beezy to try and send or receive a picture message. The only time I ever use Internet now is if I have Wifi. I sent it into Samsung, got it back more than a week later and all they did was take the update the GS3 received while they had it. It seems as though if I'm in a 4G area, the data works fine, but other than that, it's almost nonexistent. Can anyone help me, please?

I don't know what to say bro. Is it just your area? How does your phone do on other areas? If it works in other areas then it's just bad service in your area? How does someone else's phone act around your house. You should compare it to another phone and see if that one loses data.

I have 6 other people in my family and all of them live either in my house or down the street and we're all on Verizon. Their service is fine. I say it has to do with something with the phone.

Lame man. My issues were terrible until I switched to synergy. I'm on the he modem now but have had luck with lg1 as well. HD was **** on my phone.
Have you tried any modem swaps? Comparing service on hour Samsung to say a Motorola or an iPhone will make you pull your hair out. I fell into it as well. My wife's iPhone wouldnt drop 3g and my old Motorola got great service in the same spot my s3 would drop signal/go to 1x.
Things really got ****ed up when I went to an area with 4g. Watching my phone, with 4 bars of 4g drop to 3g then to 1x, to no service at all for a few minutes then repeat the process over and over again made me RAGE!

Well, my issue isn't like that when I'm in a 4G area. That's why it doesn't make any sense. The service here is fine, my phone just doesn't like it. I've tried every modem out there so far, and none have helped.
