Has anyone else experienced any issues with 4G not connecting after changes in data connection strength?
I'm usually riding the subway to and from work so am not really using 4G and then have WiFi as soon as I get into the office.
Took a cab this morning and had 4G during the ride but had a spot where it dropped out. The connection never picked up again unless I manually turned 4G off and back on.
Running Starburst 1.9.8
Anyone else have this issue?
well i just go the phone a few days ago and haven't rooted yet but i did manually flash the ek02 update. my phone will drop 4g and scan but after maybe 1 or 2 attempts it will not try to scan again. just noticing it so i will keep an eye on whats going on. looked at the info in ##data# and ti looks like its set to rescan every 120 seconds so not sure whats going on.

I'm having trouble with my EVO staying in 3G coverage. My phone is fully rooted and running Froyo (The problems were the same with the Eclair build however), have the 2.05+ radio installed (however the problems were the same with the 1.39 radio as well) and I'm living in Michigan.
At any given time my phone will slip into 1X coverage and will seem to lock in there. When I first received the phone I felt like the phone quality was subpar compared to the Hero I had prior. I'm not sure if its been a firmware issue or network issue or simply a phone issue (starting to think the later), but hoping its a simple fix with something else.
About a week ago I was on a trip across Michigan which should have had 3g coverage the entire way (I was a passenger and trying to use wireless tethering to do some work along the trip). I would constantly go into 1X and would have to restart my phone to get back in 3G. Even at home I'll go into 1X and will have to reboot my phone to get it back to 3G.
I've tried Real Signal as well during these times and it also shows no 3G signal.
Anyways, anyone else experience this? Is it likely a bad radio or something else. I hate to have to return the phone and go through that process plus root again but I might have to at this point.
Thanks for any help that can be provided!!
Hmmm, whereabouts in MI? I am all over the south east and have never seen my phone drop out of 3G yet.
Have you tried wiping everything and trying stock rom w/OTA 1.47 just to make sure it isn't the ROM?
I am having the exact same problem. Using 2.0xxx radio and Fresh 0.5.3. I recently exchanged my phone and got a new one. The first phone did not do this
Try this:
When it shows you no 3G coverage, instead of restarting, go to-- SETTINGS> WIRELESS & NETWORKS> scroll down and look at "Mobile Network". When i get the 3g problem it says "Connection Failed". I think uncheck that box and re-check it and it connects back to 3g again (for a time, but then I have to do it again).
My MOBILE NETWORK settings are: Data Roaming = OFF, Always-on mobile data = ON, and CDM Roaming mode is set to: SPRINT only. Call guard = ON but i dunno what that means.
I dunno wtf is going on with this. Im in Houston and this issue is really pissing me off because i actually got a Novatek screen this time and don't want to risk taking the phone back and getting the Epson...
Anyone else experiencing this retarded issue?
Elegant: I'm in SE Michigan as well. I've tried several roms and have had issues with them all. I'm currently using a Froyo rom with similar issues as I've had with stock and other eclair roms.
As for checking/unchecking the box as you stated in Froyo I don't have that option available... I'm sure there's another way to get to it but I can't through settings. I think there was a #* code to get to where you are talking about but I'd have to look again.
It is a very annoying issue and like yourself I don't want to have to return my phone if there's a simple fix.
On a side note: How do I find out what panel I have? I've been considering the kernel that would get rid of the 30 fps cap but haven't yet pulled the trigger in part because I don't know which panel I have - and because I need to learn a little more about it before I go ahead with it.
http://forum.xda-developers.com/showthread.php?t=719763
Post 3 tells how to determine screen
Thanks for your help - got the kernel and now get around 40 FPS. Now if I can just figure out why the phone goes in and out of 3g on occasion. Its really not as big a deal when I'm at home but when I travel it is a pain.
well i returned my phone and got one with an Epson screen. im using Fresh 1.0.1 and it is even worse. i cant even use 3g data for more than 5 seconds before it disconnects. i've read some stuff about APN but dont know how to refresh/update them. i've updated PRL and Profile and nothing helps. how am i having this problem with 2 phones running 2 different ROMs? last rom was fresh 0.5.3 and now it is fresh 1.0.1...
anyone help with this APN issue? (i dont even know what APN stands for)
i actually am using the kernel for 55 FPS for Epson screens. would that be a factor either?
I'm and having the same issue with 3g.
Every thing worked fine with the first stock root of 1.32.651.1, PRI 1.40_003, PRL 60666.
With the second root of 1.47.651.1, PRI 1.34.651.1 now my 3g is unstable.
I don't know what FPS has to do with any of this, but I put radio radio-1.39.00.04.26 and it seems to improve a tiny bit, but I don't know how to update back to PRI 1.40_003.
Not happy
Also having problems in SE Michigan. Just started today after installation of Fresh 1.0.1 and the new radios. I also have a co-worker with and unrooted EVO and the latest OTA/Radio with the same problem.
I have a rooted EVO (DC 3.2.3). My wife has a stock EVO (fully updated).
Last night our phones started bouncing between roaming/sprint 3G, while we were sitting at home.
We started getting this error if we turned off Data Roam:
"Data Call Failure
Error Code 67: Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again."
The error pops every time it tries to connect to Sprint's mobile network and fails.
We also live in Michigan. Perhaps they are doing provisioning?
Rebooting + update Profile/PRL seems to help, sometimes, but not permanently.
I am having the same issue with my 3g coverage.
When I go into my settings and turn mobile network on, it connects but then immediately says connection failed.
Does anyone have any suggestions as this is getting really annoying and frustrating.
Went to a Sprint store last night; apparently Michigan was having some significant network issues (the store reps said their phones kept getting disconnected as well), and that it was expected to be resolved by sometime today. After a reboot last night, I haven't had any more issues myself.
Hey guys. I'm running on Baked Snack v9.6 with everything running smoothly except for my 4G. I can turn on 4G and it scans and connects but it will only stay connected for a certain period of time (in most cases, 3-5 minutes). It loses connection and goes back to 3G.
To get 4G back up and running again, I need to re-update my Profile. Does anyone know what's going on? Is there a 4G log somewhere on my phone so I can tell what's actually happening? Why i'm getting dropped from the 4G network?
Also, my hotspot isn't working too well. I get the message code 67... What's up with that?
Thanks!!
I know there are a lot of posts about internet connection problems, but I couldn't find anything exactly like my issue.
If I only have 3g on, my Evo will connect and stay connected for a few minutes, then it will disconnect for about 20 seconds, and reconnect agaoin for another few minutes... and the cycle continues.
If I turn 4g on and 3g off, the same thing happens with the 4g.
If I have 3g and 4g on, the same things happens except sometimes 3g will be the one to connect and sometimes 4g.
Wifi works great.
My Evo is brand new and recently rooted, running Myn's Rom RLS4.
anyone had similar situation or resolutions?
THnkas!
there are only pockets of 4G so far. dont expect there to be 4G around like 3G is. as it is, 3G still isnt dat big/nation wide, but 4G is like rare. its like a needle in a haystack. the needle is 4G surrounded by the Hay/3G
Thanks,
the thing though is that my wife's unrooted Evo always maintains a strong 4g connection.
It wouldn't bother me too much the same thing happens when I use 3g. it reconnects every 5 minutes or so. Maybe rooting it caused damage?
Could flashing a different radio or wimax help?

Don't flash radios... that is all
For anyone with similar problem, I found my answer here and fixed my connectivity issueshttp://forum.xda-developers.com/archive/index.php/t-704845.html.

I don't think it has anything to do with the ROM.
If when you are connected to 4G you can access the internet, only suddenly 4G it drops for no reason and switch to 3G and then reconnects to 4G and goes on and on, below is the solution. if when you are connected to 4G you can not access the internet at all, the below wont fix it for you and it is probably a problem with your rom.
You will need your msl code to fix this, loop up in the forums to to obtain your msl code from Sprint:
hit ##DATA# > Edit mode.
Put in your msl code
Chose WIMAX
Scroll down to Wimax_Idle_Sleep
Change the value from 10 to 300.
Click menu, commit changes and restart the phone.
This fixed it for me and i never drop 4g (when in good coverage) again.
Basically Sprint has some STUPID setting that tells 4g to go into "sleep mode" of no data is passed on the 4g connection after 10 seconds which is essentially disconnecting 4g.
The problem is it goes into sleep mode (disconnecting), but then rescans and look for a 4G signal > reconnects to 4g and if no data will be passed in 10sec it will do the same again in an endless loop.
10sec to put a connection into sleep mode is really low so change it to 300sec.
The odd thing is that this is only happening in certain locations and with certain towers.
I tried to call Sprint and explain about this issue but my attempts fell on death ears.
Go ahead and try the above. if it helps you please someone make this a sticky as you are not the first i see having the issue.

You'll need your msl number to do this. SImply download msl reader from the market.
Can you change any of the other settings that would make it work better?
Scan attempt
Scan retry
Thanks for this info, I gave it a try but I still cannot connect without doing a profile update and or PRL update.

With Wifi on, if you loose the connection it drops the 4g and 3g signal. Can someone duplicate this to verify? The three times I had LOS is was connected to my home router and went to the store. Toggling airplane mode did not resolve the issue only resetting the phone.
Happens to me even with WiFi off all day long.
All of my LOS happened without being connected to Wifi...
Weird. I had LOS extremely frequently yesterday (every 10-15 minutes). Saw this and ran without wifi today. No LOS. May just be luck. Ill turn wifi back on tomorrow and see what happens. Sucks all phones react differently.

Doesn't do it to me. Sorry. Nice try though.
Sent From My Evo Killer!!!
I already have logged 2 LOS today. I have not been connected to WIFI yet today.
It may not be the source of the LOS, but if it reliably triggers it it will make diagnosing it far easier. I'll try it out today.
More LOS then 20 hours without LOS
I am currently running Starburst 1.5. BTW I was running Starburst 1.4 about six hours prior to when I performed the toggle.
Yesterday, LOS returned, approximately every 15 - 30 minutes. During a LOS I was able to regain signal without a reboot. I toggled Roam from Automatic to Sprint Only and then back. The signal came up, then within a few minutes I got the Roaming screen, which I set to do not ask. That is the first time I saw that screen on my ET4G. I have not had loss of signal since yesterday almost twenty hours ago.
Toggle Roaming Network from Automatic to Sprint.
Wireless and Network> Roaming Mode>
Does your phone get extremely hot during LOS?
No not warm

I never had a LOS till installed stock kernel with CWM and I have 1..maybe 2 a day and I can live with that. I did discover why I can't get an erection after drink for 7 hours though...I will post a tutorial later on it.
I originally thought WiFi might be the issue as well but I've had LOS with 3G. I haven't had LOS for almost two days since doing the MSL activation thing and going back to stock.
Ok guys, having a real problem here. Often when I am connected to either 3g or wifi my phone will stop picking up signal suddenly. AIt's almost every time and I will have to disconnect from the network manually and reconnect and it will instantly pick up signal again for a while then it'll repeat. When it suddenly stops it doesn't show on the status bar that I have lost any signal. With 3g its kinda just at a stand still not receiving or uploading and with wifi it just stays the same but I'm still not picking up a signal because by web pages won't load neither will other apps that require network load until I manully disconnect and reconnect. Is anyone else having a problem like this? I don't think it was like this when I firs got my phone a month ago. I'm at a loss. Any help is much appreciated. Oh I'm completely stock btw haven't rooted........(yet) lol

It has happened to me a couple times that I have noticed. I will be streaming music and walking and all of a sudden, nothing.
Even a soft reboot does not help. It will require a full reboot generally to solve the issue. I have not been able to identify the issue specifically. I suspect it might be related to LTE testing in my area.
What's the LTE status in your area?
No lte yet but as I stated earlier it happens on wifi too. It'll still show that the signal is connected but my pages want load at all after it happens and when I try to refresh it'll say that the webpage could not load because there is no network. Only until I manually shut off 3g or wifi in the settings and turn it back on will it pick up signal again but only for about 5 minutes. This has happened in various locations on 3g and wifi and will even happen at home wifi.

This has happened to me as well... A lot . Stock.. on various roms.. No lte as well.. But it's in the works

I've had this problem too. Sprint replaced my phone and it never happened again.
I think reactivating hands free actually fixed my problem...for now anyway. It's not losing network like it was before. All I did was enter on the phone dial pad ##72786# that'll reactivate. Hope this helps
