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?
Sent from my Evo using XDA App
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.

I rooted my phone about a month ago and went to MikFroyo 4.4 ROM very soon after. I did alot of research and found that MikFroyo was supposed to have working 4G, but for me it isnt working. I have working RSA keys and I live in a 4G area. Can anyone help me??? I live in a suburb outside of Chicago.
Did your 4G ever work? Is it connecting then dropping? Are you running the latest radio and PRI?
Yes it did work before I rooted. I believe I am using the correct radio, but can you tell me how i can check that? When I turn on 4G it starts scanning and just keeps scanning. Everything else on the phone works awesome. I just really want 4G.
This doesn't help but just so you know I tested the 4G and it does work. It scans and disconnects or connects pretty quick.
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 have my Galaxy Nexus running CM10 (don't think that would make a difference, but who knows?). I was able to connect to 4g a few weeks ago, but recently I have found that I am unable to connect to 4g. I live Manhattan, KS and Overland Park, KS which are both Sprint 4g markets. I turn mobile data on and select LTE/CDMA and the phone just sits there without any data connection. Sometimes 3g will pop up, but that doesn't happen often. I have updated both my PRL and Profile from Sprint, but that didn't do anything. Any suggestions?
More on this. I re-installed CM10 and 4g was working fine until I connected to the Wifi network I usually use. Once I disconnected from that, I can't get 4g again. Can anybody help?
Probably an issue with the nightlies.. Make a backup, wipe, and flash back to stock?
Rooted and tether enabled stock JB is actually quite nice, FWIW.
I've found that this phone's ability to transfer from 3G to 4G data is absurdly slow, if not completely useless. It also seems that it will never switch if there is data transfer in progress. The only reliable way to make it work is to airplane for about 10 seconds, then turn it back on. If there is 4G coverage, it will come back on immediately into 4G. Now that I think about it, the same thing seems to happen going from 1X to 3G as well.
Example of a common daily routine... When I leave work and walk outside, there is full strength 4G. But the phone will be sitting on 3G from when I was inside. It will not switch to 4G unless I airplane it first to cut it off and back on. The 3G data here is literally like a dialup 14.4 modem. So it will just sit there trying to sync or do whatever its doing until the cows come home. It will never change to the readily available 15mbs 4G data.
It is so bad, I had to make a tasker function to airplane, wait 12 seconds, and turn it back on. I made it a widget called "Reset 3G/4G".
Any way to fix this crap?
Sorry if I missed it but are you stock? Or are you rooted? Or are you rooted and running stock/custom ROM? If so, what ROM?

Rooted with the FreeGS3 ROM.
My EVO had the same behavior where it wouldn't switch from 1X to 3G if there was active data transfer. Which makes no sense. That's like not changing lanes on the highway because you'll have to look in the mirror first.

Maybe not, but the phone has to pause the connection, disconnect one radio, start up the other, wait for it to be on, connect using that radio, and then finally resume the data transfer.
I don't expect it to happen in a matter of seconds. But what you describe should not take 5, 10, 20 minutes to accomplish. It will not switch between 1x, 3g, and 4g so long as there is data transfer in progress.

True, but it may just be the apps blocking it. If theyre using it, the connection wont get dropped until it goes inactive, if I remember correctly
Here's why that makes no sense. App needs data connection. Phone in 1x with a 20kbps connection, trying to download music or photos. 3g or 4g is available. But instead of switching to it, it will just sit there until the app crashes, or tomorrow when it is done downloading.
Hmm... I'm on stock rooted MB1, and I'm also roaming at work, but there's a somewhat reliable LTE signal right outside the building, and as soon as I walk outside, I see my phone go from roaming, to not roaming, and then I see it switch to 4G in a matter of seconds. I don't need to turn on or off airplane mode or any sort of trick like that. Maybe it's ROM related? Custom kernel related? I'm not saying it is, I'm just listing possibilities.
Then again, I'm also not trying to download music or photos when I see I have a 1x connection, though my current ROM doesn't really tell me if I'm on 1x or not, so I just don't do anything network intensive when in low connection areas.
I just changed some settings in the ##DATA# menu. We'll see if that helps.
