4G Shows Connected but no internet

Does any one have experience with this issue. 4G will connect and it says active, but internet connection wont work at all for any app, browser, youtube, etc. It will work fine when I switch back to 3G.

yeah it happens alot. its seems after 4g goes dormant, apps have difficulty accessing it even tho it shows connected.
There is a thread floating around that has tweaked wimax settings to prevent it from happening

I am having the same problem on mine. However it seems permanent. I am ready to return the phone to sprint. Even when it first connects it can not access the internet.

Mines seems to be a permanant one also. Not a dormant issue, shows active even reboot and reconnect nothing is working right now about to head to sprint store.

I notice that you're located in Boston. This is currently an issue that a lot of people in Boston (myself included) have been experiencing since the 17th. I've called Sprint numerous times about it, but none of the reps I've spoken to knew anything about the issue. There's currently a thread about it on the Sprint forums, but I can't post the link since I don't have enough posts. Just Google "4G Connection Issue - Boston 11.17.2011".

Yep, I was in Boston all last week and starting the 17th I could connect to 4G but had no actual data. I thought it was a problem with my phone but as soon as I got home to Chicago I had no issues with 4G.

Thanks, just found that out coming back from the Sprint Store all of their 4G phones were having the same problem. Argh unroooted and remove stuff for nothing haha.

Glad I read this. I am in Boston now and wondering wtf is going on. I was about to try to flash my phone back to stock.

haha, i did the same thing, i am glad its not the phone, hopefully sprint will fix it soon

I live in boston and I just got the phone on saturday and was wondering why i coudnt get 4g, the sales rep (whome was a close friend of mine) said it might have been because of the weak signal inside the building so i checked outside and still had no connection. I flashed to starbursts rom and still had no 4g even though it showed 4 bars. was going to unroot and return the phone today but i guess not!

http://www.sprintfeed.com/2011/11/northeast-4g-outage/
post your issues here, try to gather more support.

It's back up now I think, but I do feel like I got the run around with the call center saying there was no report of outage in my area and I wasted time driving to a sprint center with a reference trouble ticket all for nothing.

I'm not too far from boston, Yet right now Not only is my 4G messed up but I now no longer have any 3G, roaming only at this point.

4g service but no 3g?

This JUST started yesterday...
So, yesterday at work I noticed I had no data...so I did the typical restart...still no data...I shrugged it off and went on my way. As I was driving I had data again. I use wifi at home, so when I got home I didnt notice any issues and honestly kinda forgot about it. Well on my way back to work this morning I looked at my phone...had full 4g service...all seemed well. Then I got to my office...
Now let me explain I DO have 4g in this area but honestly...its only a solid 4g outside. Its not the greatest indoors. Well in my office I only get 4g if I'm standing at the window or one "sweet" spot at my desk. So 99% of the time I'm in 3g. Well to make a long story short my 3g antenna seems to be borked. I can pull 4g fine...on lunch today I was in 4g and it was working great. However, when I'm in 3g I get zero data...my phone doesnt work in 3g only 4g.
I called verizon and they just decided to send me a new phone...
I have rooted my phone and I have put the newest radio on. That was awhile ago though. Tonight I'm going to try flashing a different radio but has anyone else had this problem?
Again I get NO 3g service only 4g. In an area where 4g is spotty thats NOT good.
Thanks!

Yes, I had the same issue. The first Nexus I had gave me spotty 4G service and never went to 3G in the couple of weeks I had it. Amazon sent me a replacement which is rock-solid. I get solid 4G coverage where I should (my wife and several coworkers have LTE phones so I know where I should) and when I don't have that 3G kicks right in.
I think you should definitely expected better results with a replacement. Good luck.

I had chosen to use 3G over 4G to save battery life. After about a week with the phone I began to notice that I can hardly ever get 3G reception any more, even though 4G reception has always been excellent. I don't think it is a problem with the phone, but rather Verizon tinkering with its network.

I was having the same problem all day today.
I switch the phone to CDMA during the day and use the office's WiFi for data. However, I noticed today as I dropped my daughter off at school after lunch that I had voice only and no data. Her school is the first tower north of my office that doesn't have an LTE radio, so I normally just get 3G.
Not today.
I drove back to the office and I was able to get data through the LTE radio, but the data connection would go dead as soon as I switched to CDMA. I thought there might be something wrong with the CDMA tower, but two of my co-workers had Thunderbolts set to CDMA only and they were having no problems getting data connections.
I talked with tech support for a good couple hours this afternoon and they had nothing for me. Eventually I flashed the leaked 4.0.3 radios and CDMA magically started working again.
Did the new radios fixed the problem, or is it just a coincidence?
Hmmm...

I have been having the same issue since yesterday. Verizon said there is no outages in the area. I had no data all the way home from CT to NY and finally when I got home at night 4G worked. 4G was working in and out on my way in so I forced CDMA to see if that worked and I have been unable to get anything since. I have a new SIM coming today, but somehow I do not think that will solve the issue.

I've noticed this too. I was turning my LTE off thinking it would use 3g, but I'm noticing now that many times I either have 4g or no data at all.

I'm having the exact same problems and registered here to see what the resolution is. I'm apprehensive to root as I am still within the 15 day return window and quite frankly for 300$ I think this is total BS. Never had a dropped call, missed or unsent text on the 3g network on my old Dinc and I've lived in the same place for 2 years.
OP- could you keep this updated on how your new device works out?

same exact thing happened to me. I'm already on my second nexus and I didn't want a refurb or to lose root. So I flash android revolution hd , used tb to delete all my apps, and hid all signs of root including deleting su. I took it to Verizon and they gave me a new sim card. It was OK for about a day then started acting up again. So I called them from my wife's phone and they had to reset my number to the network and its been fine since

What do you mean by reset your number to your network? Never heard that term before

I'm not exactly sure, some techs don't know about it. When I had my charge it had no data. So they reset my number and phone to the network and I immediately got data back

(T-Mobile) Randomly Losing Signal

My gsiii for some odd reason loses 4G and sometimes even service. Last night when i was on a call, it dropped and the signal reflected that i was running on edge then it switched to someting that said "G." I looked at my brother's siii and he was also on edge. So i tried putting it on airplane mode however it would not go through. It's as if i never pressed anything. So i had to restart the phone and it was on airplane mode, so i took it off then about a minute and a half later i got 4G back. Today when i was browsing the web, i randomly lost 4G again but this time i continued to have signal just no data. About a minute later I got it back. About a minute later i lost it again and regained it about a minute later. I havent noticed anything else about the phone and ive had it for about a week and last night was the first time that i restarted it. Any ideas? Has anyone else experienced this? Thanks!

I'm also having the same problem it just happened to me today also and happened the other day when I restarted phone it did nothing then I did airplane mode that didn't do anything so I clicked the enable packet data off then on an item came back in hoping it's not going to be a hardware problem cause I've dropped calls for no reason and had no service or bars were showing but had no edge 4G etc

Yeah it's really weird, when I was using mt4g, it would do that randomly as well, I'm not sure if it's a phone or a network issue. Anyone else experiencing this random drop in data?

Same here I think it's a common issue with tmobile devices.

I think is just the network it had happened to me but while driving some place and Idk if is the coverage but other then that I do see going from h+ and 3g, I have a custom theme install

I just moved from Sprint to Tmo and I'm getting the same on my S3. It would look like i have good 4g coverage with 3 bars then all of a sudden it goes to Edge. So I have to wait for it to go back to 4g to start surfing. Edge is like 15kbps for me which is not even modem speed which is 56k. If I accidentally start surfing on Edge it seems to wanna stick to Edge until I close whats using data then it will eventually go to 4g. But when I get 4g its awesome and I get over between 6meg to 12 but only 40% of the time. I called Tmo and they said I have great 4g coverage where I'm at....ya sure.

I've only experienced outright loss of signal once, which was last night. So far nothing else has happened really. It was just odd that my phone won't even go into airplane mode until I rebooted the device.

Same thing happened to me. I was actually quite worried and about to send my phone back. Everything seems to be working okay now. No issues.

this has driven me mad for the past few days. recently I upgraded to a S3 and my dad got a S 4G (which was released 2 years ago). while we were in Costco, my S3 randomly switched to Edge while the S 4G has 4G all the time. ALso we were on vacation to San Francisco so I could experience "Tmo largest 4G network." While we were in a hotel in Fremont, my S3 again switched to Edge and back to 4G randomly while the S 4G had 4G. also the signal is not stable at all. sometimes(1 or 2 times) it even dropped to zero bar. SOMETHING wrong with samsung phones. I read somewhere someone had this issue with the S2 also. I can live with the HSPA+ for 2 years, but hey dont give me random Edge like that
I plan to go exchange for a new phone at Costco... probably a new S3 to see if the issue still exists...

T-Mobile's 4G network works in a interesting way (do all HSPA+ networks work this way?). They idle in UMTS mode (3G) until there is network activity, and then switch to HSPA+ (4G) mode. The network changing is an automatic thing does to save battery life ("Cellular standby" is often the largest battery drains).
Ever use an AOSP-based ROM (i.e. Cyanogenmod)? You'll sometimes see the network indicator in the status bar switch between 3G to H+ to 4G, etc as you use it. Stock T-Mobile ROMs are hard-coded to always say "4G", but if you go to Settings → About phone → Status, you can watch the network type there change as well as the phone does anything over the cellular network.
You should never be dropping to GPRS or EDGE. Perhaps the mechanism described is defective on your phone?

Happened again today. Had signal but no 4G, not even Edge, just bars. i think it happens whenever the signals low. Thoughts?

I'm having the same issue at my work place. I'm getting Edge (50-80%) more often at my desk, when previously with my SGS2 it stayed at 4G all the time. Checking Cellstandby I am getting 31% time without signal.
Is there a setting to force 4g connection?
My office is in Cupertino, CA and reception is not bad in general, but there are a few locations with 4G dead spots.
I'll check my reception again at home (Santa Clara, CA). I can do a side by side comparison with my SGS2 (now belongs to my wife).
On call with TMO right now, they are going to do a reset of the phone in their system, then I will need to do a reboot. Fingers X'd that things will improve.
BTW, what options do I have to get a replacement phone if I bought mine from Walmart? Do I need to send it in or can I do an instore exchange? Just got it on Sunday. Will I incur any fees if I returned the phone?
---
Reset didn't work. Passed on to level 2, there submitting a service request to check reception in the area. Need to follow-up on Friday if the reception is still bad. Since I'm in Cali I do have 30 days to return the phone.

I have similar reception issue but I dont lose signal completely. I will go from 4g(hspa+) to 3g to edge then it will switch back to 4g after 30secs-60secs. Quite annoying since I will be stationary and it will happen and it happens more when Im in a car. Never had this problem when I had the Nexus One.

Question. With your s2 what happens if you're in an area without 4g? Do you get edge?
Sent from my SGH-T999 using Tapatalk 2

I am having the same issue. I had perfect 4g coverage all over my town, (I live in south texas). The problems started 2 days ago, when I lost all 4g coverage. I took out my sim card and placed it back in and the 4g logo came back on. But now I have been noticing that my cell signal will completely drop and then slowly come back up. This has happened several times. I also went to tmobile and changed my micro sim card and the issue remains. AND NOW I AM ON EDGE!!!!!

Has anyone been able to get a replacement and did it fix the problem?

Dropping data on Verizon?

Coming from a moto droid maxx and liking the native super fast Google experience with Marshmallow.
Phone is dropping data periodically on Verizon and will only pick it back up by changing the preferred network type. Anybody else having this problem? If not, maybe I just have a bad device.
Thanks

I am having the same problem. I posted about it a few days ago. No solution yet unfortunately
Sent from my Nexus 5X using Tapatalk

No issues here but my house is in a poor reception area. A quick toggle to airplane mode when I get 3g will get me back on to 4g. I'm used to doing that for as long as I can remember, not just this phone

My Nexus 5x on Verizon comes Mon or Tues. I sure as heck hope it doesn't do that. That would be a major problem, as I'm finally getting a real Nexus on Verizon to get away from buggy aosp/cm roms for Samsungs on Verizon.

I just saw this thread. The same exact thing is happening to me.
Is there any negative to having the preferred network type set to "LTE / CDMA". Technically, that is what Verizon's network is.
Do you still sporadically drop data when your preferred network type is set to LTE / CDMA? I just changed it this morning. So far so good.

I was set to LTE/CDMA when it first happened and was not on WiFi.
Since then, tried different apn settings and Global instead of LTE/CDMA with no luck. Just tried setting cellular data to on, even when connected to WiFi.
Over the past 2 days it has happened 3 times, so frequency isn't that high but definitely an annoyance.
Sent from my Nexus 5X using Tapatalk

That sounds pretty frequent to me.
Hey, my quoting function isn't working, from Tapatalk app.

I just stuck my VZW nano SIM in, didn't adjust any of the options, no problems with data drop thus far

Ya I've had my 5x since Tuesday at 11 am. No network problems

No problems here, signal strength is better both at home and work as compared to my prior phone.
Maybe try a new nano sim from Verizon? The corporate stores will give them away for free. (Have seen posts where folks say the customer service line will mail them for free as well.)

Just adding my experience to the thread: my Nexus 5X on Verizon network is struggling daily with maintaining a cellular connection. I have no issues if I'm in an area where you would typically have a strong signal. However, when I'm in the 1 or 2 bar range, I cannot even receive text messages, much less data. The phone REALLY struggles with group texts. I'm going to full reset and see if that helps things.

Noticed that dropping data seems to coincide with incoming MMS messages, specifically group texts.

I am seeing this as well. What text messaging application are you using....

Did a full reset help at all?

Having the same problems. I spoke to a tech at Verizon and they said the SIM card I'm using is being "retired" (their words) and I should go to a retail store to get a replacement. This was after trying to dial their automated smartphone activation number and ending up on the line with a tech. Going today to get a new SIM card and will post the results.

Experienced this with both hangouts and messenger. Hopefully the SIM card resolves it. Keep us posted !

Same issues here even with a new SIM...I also noticed it doesn't go to 3G, its either LTE or nothing? Group messaging is pretty much worthless... Sending phone back and going back to Moto X Pure...had that previous and absolutely no issues

Update: new SIM seems to have fixed the problem with drops. Tested several group MMS and it seems to be OK. Verizon reps were clueless on activating the SIM and took a while to finally give in to my request to just take the card home and activate in my old Moto X. I activated it with a Verizon rep on the phone and then transferred the SIM to the N5X with no issues. Got immediate LTE and was able to do everything as expected.

Is your signal strength any better or worse with the new sim? My nano sim is ancient and wondering if it's one getting retired...

Signal strength is the same and unfortunately the problem came back. It's actually my wife's phone. I bought one for her and one for myself. Mine has been fine on Verizon since I switched from my M8 but she's been having the signal drop problem. The new SIM did not resolve it permanently. I'm requesting a new device from Google today.

AT&T coverage issue or Pixel 2 XL radio/software issue?

No proof but I feel like my 2 XL has been having signal issues on AT&T. So either AT&T coverage got worse on my train ride or the phone is causing this.
I could have full bars on H+ and LTE but no internet, if I turn off mobile data and turn back on it goes back to the same bars but this time there is an x by the bars. I don't remember service being this bad on my train rides a few months ago, always run the latest software (all stock).
My train ride is on a very popular train route through NJ to NYC. Even when we stop in Newark, not getting service and I know for sure I never had a problem in Newark.
Besides trying a different phone, any other way to determine if its my phone or the service? Anyone else notice anything similar?

My wife's phone was doing a similar thing but also failing to send and receive mms messages. A new sim card ultimately fixed it.

Now that you mention it, I was having problems with text not going through at first. I had to hit resend text for it to go through. I am going to go to the AT&T store and get a new sim. Thanks, hopefully this works.
Went to store by office, he looked at my SIM card settings (APN) and said they were not correct so he updated a bunch of things. I'll see how signal is during my normal commuting and hopefully it helps.
