I live in the suburbs of Houston where the WiMAX coverage is kind of spotty. If I leave an area of coverage for more than like say a minute, my 4G will stop attempting to scan for a new 4G signal and never attempt to reconnect even if I enter a new area with 4G coverage. I have to manually toggle the connection in the notification bar.
I've searched the forums and noticed several posts describing the same issue.
Does anyone have a solution?

I have seen this issue as well, do you use bluetooth? I know its a random question but I have only noticed this issue with mine when I have the bluetooth on.

Bluetooth is not turned for on my device.
Bump. Anyone else having this issue?
I'm using the phone app so I don't know the link, but there's a link in general, I think, that describes increasing 4g performance. There's two simple tweaks to do and some involved ones. I just did the two simple ones. One is to change the retry interval down to 15 seconds and the minimum signal level for 4g lock is -110db. Those two changes made a noticeable improvement on fringe areas and inside for me.

I did those tweaks, that is not the issue. I have tried all the WiMax_Scan_Retry from 1 to 300 and the WiMAX will never reconnect.
For example: I do not have 4G at school and I have 4G at home. If I drive to school, the 4G will disconnect.
Then when I drive home back into 4G coverage and go to sleep even after 10 hours, the 4G will not reconnect.
Bump!!! Also have this issue.

Try doing what most people do, when you know your leaving a 4g area turn it off. Then turn it back on when you get home. No sense in wasting battery. That and it only takes a couple seconds to turn out back on and reconnect.

I have extended battery that will literally last days even with 4G on so that is not an issue for me. Besides, this is not a viable solution if I want 4G in the car and it moves in and out of areas of spotty coverage. 3G where I live is about as fast as 1x.
Mod? Rooted? Modem?
Is your phone software on stock?
What OTA updates/mods are you running?
Kernel/Modem versions?
It would be good to know of the people seeing these problems have similar software/mods/modems.

I agree. Post your setup in detail. It will help to narrow this issue down. For example I had similar prob's on EL13 modem but with 26/29 flash all is good.
So more info plz.

I tried these:
Stock/Stock+Root/Starburst/Caulkin
EK02/EL26/EL29
Rogue1.3/1.4
This may be an example where adjusting the WiMax settings in ##data# with MSL number will help. Try lowering minimum signal picked up from -89 to -110, you can also change how long it stays connected and how fast it reconnects too...and here's where to read about it all...I did it on my OG Epic, Nexus, and this phone but slightly modified settings..it could also be a kernel thing too. Some of the Nexus ICS ones do that and wont reconnect until you go into settings and toggle

Ok now it's time to go to your local sprint store. Im outa ideas. You have done morethan most B4 choking a rep.LoL.
I have this same problem.. Sometimes sitting in the living room. When im outside i get 4 bars of 4g but inside i get 1. if some reason i get disconected, it seems to switch over to 3g and stay there without scanning again. If i walk outside again, still stays 3g until i toggle off and on 4g again....

Anyone know of an app that will toggle 4g for us when it loses connection?
Or maybe a tasker profile? I tried in tasker, but I can't seem to get it to do more than basic things. There a couple spots in town that always lose 4g when I drive by and never reconnects as well. 3g is slower than when I use roam control on 1x verizon.

Lately when I turn on 4g it will connect and then go to sleep indicated by the "ZZZ" but if I try to use data i get no connection messages and the "ZZZ" doesn't go away indicating it is trying to connect. I turn it off and 3G works fine. Sometimes a reboot fixes it for a while. For some reason this morning after rebooting I got the message about updating the modem from EF02 to EF10 even though I am on the EC05 modem. Could it be a hardware problem with my 4G or does anyone have any other ideas?
Did you try adjusting the minimal 4G reception in the "Want better 4G" thread. It worked great for me.
Sent from my SPH-D700 using xda premium
Yes I did that when it was first posted and it has worked fine up until recently. I have 2 other Epics in my house both rinning SFR 1.2 also but I haven't done that mod yet to them. I was considering getting the original values off one of them and changing mine back to see if that helped.
I have noticed that some apps wake up 4G and some do not. For example, I would do a speed test, it wouldn't work, I load a web page, then try speed test, and it would work.
Also, try turning off then on 4G.

I figured there may be a problem waking 4G but even Browser, Google Maps and Market don't work when this happens. I would think if it was a tower issue I wouldn't show connected would I?
Just curious if this happened to anyone or is it just me: most of the time I'm connected to wifi to save battery (home, school, etc) and when I'm out of range it should automatically connect me to the 3g network but it's not. I check settings and 3g is still enabled. Anyone know why?

I am also experiencing this. This happens to me when I am connected to WiFi with bad or no signal but then when I turn off WiFi and go to a good signal area it still registers no signal until I restart my phone then all is fine. Definitely a major bug.
ive had 2 of these phones, ive never had an issue with this. eh. maybe im lucky
Any solution to this?
Ever since I purchased this phone, I hardly get 3g signal. Will a hard reset fix this problem? I have to go by 4g or wi-fi on this phone for data.

having wifi on will actually kill your battery more because you have another radio running, thats why they give you the option to turn it off. (to save battery)
hmm thats odd though mine turns back on just fine
try a hard reset.
its deff a software issue

+1. Wifi Is definitelya battery saver. I leave wifi on all night at home. I get great battery life. I also never have the problem with 3g either. It always comes back even if I lose wifi signal.
The Evo3D Killer!!!
I noticed this in mine, so I went to Settings->Wireless and Network-> Mobile Network Data and then unchecked 3G and re-checked it and it hasn't had the problem since. Try it and report back.
a lot of users are having this issue along with low speed results on 3g, I read on another forum that Samsung/Sprint are working on it but I'd take that with a grain of salt. I fixed the radio wake up issue on my phone by doing factory reset and then going through the hands free activation again. Haven't had it since.
i'm having this issue too. Turning off wifi, or every time I go in an elevator and loose my 3g signal.
The strange thing though is I had this same problem with my OG Epic for the last two weeks I had it. I flashed back to the current Sprint rom and still had the problem. It was actually the reason I bought the Epic Touch on day 1.
I too am having 3G connection problems
My work is located a mile North of the 101 and Scottsdale and I can't get signal in my building, even if I walk to the big windows.
Of course Phoenix has no 4g so Im S.O.L.
OK does this phone actually show anything other than 4g?
I am in a 3g area and I have not ever seen anything but the 4g icon.. Unless I put it in gsm only mode. But on auto or Wcdma mode it stays on the 4g icon.
Also it seems like I have issues with the Internet staying connected even when I have signal.
Also it seems like when I leave my screen off and turn it on the signal is higher than normal but goes down within a few seconds.
Anyone else notice this?

I am having the EXACT same issues. But, I am in a 4G area. Of course I got throttled by blowing through my 5G limit in a week--damn these new toys and massively restrictive internet access at work (financial industry). So now I am on edge for a while; but with the 4G icon up, I cannot hold a data connection at all. It goes on for a few seconds or such, then nothing. The upload icon is always on, but no download. I have to force GSM mode to maintain any sort of connection. The "Auto GSM/Wcdma" does not switch modes efficiently. I think it is continually checking for a 4G connection, thus resetting the 3G/Edge connection it is making. Very frustrating. . . I am hoping someone with make a Auto/4G/3G/Edge toggle so I can drop it on the homescreen rather than digging down for it.
Same thing here. Always on 4g and my wifi is spotty like the first poster. What's the deal?

5gb in one week?? That's insane usage u might need the 10gb option..
The 3g 4g network is the same network.. some towers aren't updated and some phones don't get 4g speeds but that's why it always says 4g
sent from my real Gs move in silence like lasagna
I've been having issues after my OTA update with my phone not connecting to 4G very well. While I'm driving, or moving around in a 4G area, it disconnects (I'm guessing losing signal from one tower) and then scans for a signal and doesn't automatically re-connect. If I turn the radio off and back on, it scans and connects. If I leave it alone, it takes a while for it to reconnect.
I'm pretty sure that I didn't have this problem on EG30 or 31. Unless I'm imagining this, I'm pretty sure that it was seemlessly moving from one tower to the next without ever disconnecting, unless there wasn't any 4G coverage in the area.
Is this normal or is my phone messed up? I've since installed EL13 and still having the same issue. I'm going to try going back to stock to see if that helps.

Yes. (10 characters)
It was my understanding that with the WiMax towers, there isn't a seamless hand-off from one tower to the next, which makes sense to me as I've also had the same issue while driving.

That's strange. I could have sworn that wasn't the case before the update, but I guess I could be wrong. Does yours connect right away when going from tower to tower, or does it take a while? It seems like it almost always fails on the first scan, then re-scans 10-15 minutes later and then connects.
Anyone have an issue with their phone randomly dropping Wifi/Cell connections? Sometimes it doesn't happen for a day or two sometimes it happens 3 times in 5 minutes.
Starting to think my phone is defective...

I'm having the same issue with Wifi. It'll still show as being "connected", but there won't be any data coming through. I'll have to toggle Wifi on/off to get it back. Sometimes it'll work for a couple of hours before having the data issue again, sometimes less than a minute.
I'm on stock, rooted.

Connections optimizer is off for me too - My phone shows a clear signal disconnect and reconnect (The wifi bars/3g symbol disappears completely) during this time all data connections fails - including texts. This is happening when I'm staying in one area so it couldn't be a tower reconnection issue.
I'm going to try taking my phone into a sprint store today to see what they say.

Ah, it sounds like our issues may be different then. My issue is solely with Wi-Fi (haven't noticed issues with 3G). When it happens for me the Wi-Fi icon in the status bar doesn't change, I just can't connect to anything.

Yup, same here. Seems like the 3G radio does the same thing, but not necessarily at the same time as the WIFI. At first I thought is was only the WIFI too, but 3G is affected, though not to as severe a degree. My WIFI was actually disconnecting and failing to reconnect. Turning off connection manager made no difference. I did however notice that the WIFI at my work (WEP encryption) never seemed to do this (at least I didn't notice), so I changed my home network WPA to WEP and sure enough, it stays connected. Was still failing to load occasionally, so I went even further and changed the router to a single channel rather than "Auto" and set it to "N Only" (due to having a similar problem with a laptop I used to have, with a similar solution). Problem fixed. I'm using an Amped R10000 just FYI, not sure if it matters. Very annoying, and given the number of occurances being sufficient to start a thread, I'm assuming this is a common issue and will hopefully be fixed by a firmware update. In the meantime, we should probably all start calling Sprint daily and complaining. Maybe they're not even aware of it. Probably not enough of these phones in circulation yet for them to worry about it.
Mine will do this from time to time. Stock not rooted. I will have full 3g bars and full wifi bars and my data will just hang. If I turn off wifi everything works again. Some times when I load a game that has to connect to Facebook to play against friends I have to close the app/game, remove it from memory and reload it to get the data to work. Same thing for Pandora. It will load a song to 2% and hang until I stop wifi or reboot the phone. It's not an everyday thing but some days are worse then others.

"Good to see" from the perspective I thought it was just me. Things described by others happening to me as well. Personally, I find I like the wifi/3g auto connectivity feature - when it works. Got my SGNII on Thurs last week, and connected to wifi at work on Friday no issues. This morning, the Note picked up my work wifi without a hitch.
At home, over the weekend, I was getting spotty connection, sometimes no connection to my wifi. (Disclaimer - I have my main wifi @ N/5ghz. An access point was added with wireless G via an old Netgear router-turned-AP.) After several attempts of moving the AP from one cat6 jack to another, I finally moved it to my main level. Oddly enough, so far, so good. Certainly possible the router's radio is pooping out.
What I notice happen with connection issues though seem related to the Note seeing my wireless G, trying to connect, but unable to do so until/unless I reboot my phone. After moving to the new location/jack, everything seems to work OK now (knock on wood).
Having said that... I also think the 3g radio (HW or SW?) is a bit wonky, as my old HTC Hero seemed to have more bars at home, IIRC. Whatever it is, just seems a bit lacking, IMHO.
Sprint is updating to LTE in many markets ive noticed my 3G drops says preparing networks and reestablishes the connection to 3G. I live in Fort Wayne and issue the permits for the tower co-locates and they are close to going live with LTE here so I know thats my problem. I can live with the flakiness for a few more days. I have not had issues with WIFI drops at home.

The same thing has been happening to me here on Long Island. 3g drops and reconnects. Sometimes it doesn't and a reboot fixes it. I also notice after the disconnect and reconnect it states my PRL is unknown. I have done a PRL update many times, a Profile Update, a RTN reset, and a factory reset. This happens on the stock rom and any custom ROM. It's driving me insane!

I haven't been on the phone when it's happened so I couldn't tell you - Nothing like the LOS on the E4GT. When the data connection does cut out it immediately reconnects. Doesn't really impair the functionality of the phone but it happens enough to be annoying. With a 300$ price tag I expect my device to be without defect.

I'm not having LOS /dropped calls just data creep with LTE/Cdma setting enabled.
Speed test show same data speed numbers as CDMA only setting but when browsing data arrows tend to pause more making for slower page upload with LTE/CDMA setting enabled.
According to Sprint store tech such performance is common with that setting.

I am on CDMA only. I should have mentioned that in my first post. This does affect phone calls too as ill be on the phone and the call will drop and the "out of service area" message comes up. It doesnt matter if I'm on my Airave or not. I tried different prls which doesn't seem to make a difference. I am starting to think there is something wrong with the phone as my girlfriends S3 doesn't do this. Maybe Samsung will release some sort of update to fix this issue.

I made the change back to CDMA only mode this morning and it has solved my WiFi issues as well. I was also struggling getting a GPS lock with LTE enabled. GPS toolkit would show 20/21 satellites found but it would never get a lock. After the reboot back into CDMA mode it locked in 5 seconds.
