[Q] Unstable Internet / Network

My phone sometimes loses signal completely... other times it has a signal but I cannot connect to the net. The 3G Symbol at the top only shows that it is uploading and not downloading. any Ideas on how i can fix this?

The radio is very flaky, I believe even more so for CDMA devices. What type of phone do you have?

I get the same thing here. Almost 1 out of every 3 times coming out of sleep it is ok. Otherwise I have to go and rebuild the APN settings back to default.
Typically it has something listed but once in a while it lists nothing until I rebuild them.
These times seems like it is like the towers have stopped talking or refuse connection to my phone. Thus the reason why it uploads but not downloading any data.
2.1 had random data issues but 2.2 has some major kink either with the radio version or overall CDMA.
I have Verizon (RHOD500).

I believe it's the (Touch pro2) Rhodium 100. but not really sure how to check. But if you mean GSM or CDMA.. Its GSM

you can try re-flashing the radio, which will help if anything has been corrupted

I would try that if my WinMo has an issue. So far just android dropping data on my RHOD500.
I think it is trying to rebuild or at least re-register on the network too much causing issues with towers or internally at least.

I dnt have a problem in WM. Only within Android.

Yea... the radio drivers probably aren't perfect. Far from it, from the sound of things... I've definitely had issues with it as well. I just try to avoid making calls in Android, and receiving them always makes me leery. I've had a few important calls drop because Android decided to reboot itself...

Ahh yeah I've seen the same problems on my RHOD500...usually I know when facebook gets a refresh API error since its set to sync every hour so I just pop on/off airplane mode for a minute and I get data back.
Other then that radio seems pretty decent...I make and receive calls all day with no issues.

GSM - GNEX Signal Drop Solution - Working ROM,Radio,Kernel combos. POST HERE...

***EDIT*** I believe that I have found the solution to this issue (at least for me) by flashing the FuGuMod Kernel as advised to do by 2 users (jetrii and slyydrr) who advised me of this in the following thread here http://forum.xda-developers.com/showthread.php?t=1487056 on pages 7 and 8 respectively.
This fix may NOT work for you but I can say that it has worked for me. Please see post #33 (and onward) in this thread.
I have painstakingly been trying to find a solution to this issue and it SEEMS as if I have FINALLY found one so if I have helped you in any way then I ask that you please press the "Thanks" button and please visit the thread above and say thanks to jetrii and slyydrr as well. I also recommend that if this works for you that you go to the FuGuMod thread here http://forum.xda-developers.com/showthread.php?t=1438417 and pay tribute to nikademus for his kernel!!! I know I sure have... Also... Make SURE that you flash the correct kernel version for your ROM ie: 4.0.3 ROM = 4.0.3 Kernel, etc...
Thanks...
Hi everyone,
I have decided to start a fresh thread here as I have seen (and replied to) many threads regarding people with the GSM version of the GNEX (like I have) that are suffering from random signal loss of both data and GSM services for apparently NO REASON.
If you are also experiencing these issues I ask that you please post them here so that they are easy to follow and I also ask for anyone with ANY answsers to please post them here as well. Also... Please post what firmware you are running and any steps you have tried to fix this issue be them a failure or a success. I have done the following...
I am currently on the FoxHound v1.0 AOSP 4.0.3 firmware and experience these random signal drops. I have flashed NUMEROUS radios / modems to try and fix this with no success. I had been told by someone that the issue MAY be a BUG in the 4.0.3 AOSP ROMS but I have a hard time believing this as some people do NOT experience these same issues while on 4.0.3 ROMS.
What did work was to flash to the Android Revolution 4.0.2 ROM and on this I do NOT experience these random drops which COULD mean that the problem DOES lie in the AOSP builds of 4.0.3 but again... I have a difficult time believing this but it could be true. Also... Stock firmware (4.0.1) for me here in Canada does not experience these random signal losses either.
This is very annoying as I want to run the 4.0.3 custom ROMS for their customization capabilities, etc but I cannot keep my device in a USABLE state when on 4.0.3 so I have to go back to my trusty SGSII.
Again, please post here to voice your concerns and opinions on this and perhaps SOMEONE will be able to find us a solution.
Thanks,

are you using your carrier supplied radio?

Yup. Im on UGKL1 which is the radio that shipped on my device. I have also tried other radios (XXKL1, UGKK7, XXKG6, etc) as I mentioned as well and I still experience the same issue and others have mentioned the same things as well with no successes.

There was this one time that I had lost signal randomly (while on stock unmodified out of the box ICS) but I was able to get it back with a factory reset. After that it never happened to me again.

Thanks for the comment. May I ask what Radio your device has on it? Are you running any sort of custom ROM now? If so, what are you running?

Right now the radio is KK6 (im on stock yakju 4.0.2 now) but at the time it was what came with the phone (shipped from Rogers)

Hmmmm... Interesting... You got an OTA update to 4.0.2? I have seen other posts that people here in Canada are complaining that they have not received ANY OTA updates at all... When did you get this?
Since I have been on a custom ROM I have not seen this update obviously...

I'm on GSM with Rogers as well. I haven't noticed any significant signal drops with the exception of my basement (no cell phones get signal there - its a fortress lol). I am on 4.0.3 as well. I have read that the 4.0.4 has improved radio... so it may be worth looking into. I saw a WIP 4.0.4 GSM Rom here.

I've been experiencing this as well. I'll have a great signal, then suddenly it totally disappears, and after a few seconds the signal comes back. It's even happened during voice calls as well. I experienced this on the stock device (4.0.1). I'm now using the GummyNex rom on 4.0.3 (w/ a stock radio), and I'm still experiencing these random signal loses. (T-mobile USA in NYC, btw).
It's not a constant problem, but it happens a few times a day. enough to be an mild annoyance.

Hmmmmm... I ONLY seem to get these signal drops on 4.0.3... Weird... You have a GSM device right? Not CDMA - LTE?

I found something new to try when I get home but if anyone may want to try it now and post your results it would be very helpful and appreciated.
This is a radio from the Japanese variant of the GNEX and most people who have tried it have had good success with it... See the link below...

I THINK I am experiencing this. My phone keeps going from H+ to 3G non stop at the top. How can you tell if your signal is being dropped? (sorry new to this) I've seen posts with a network screen? showing connection but I can't seem to find this.

Haven't had any issues as far as that. There were times when I was using the browser and it said network error but everything still worked.

You will notice because the signal bars icon will go "completely blank" and for example... If you are on your lockscreen and you can see the name of your provider...It will disappear completely for a couple of seconds and then come back...

No I guess I am not experiencing this. I'm not exactly sure what the difference between H+ and 3G is but my phone seems to stay in 3G until it transfers data, when its transferring data, it goes into H+, then back into 3G. Maybe this is normal. I was just curious because I did flash Yakju and the radios when i bought it.

Well, when I first flashed 4.0.1 yakju I got notifications of being able to upgrade it OTA. However, at the time I must of messed something up when I flashed it because the updates werent successful when I went to update it. So I got fed up with it and I flashed 4.0.2 manually via fastboot.

So I flashed this radio and I get SOMEWHAT better stability but it only accesses the EDGE network and NO 3G/H... Guess this is a no go too...

HD Rom, Latest build.
Radio - XXKK6
Had the stock radio with the HD Rom, and thought that my random lost connections on market were due to my not flashing the recommended radio. Flashed the recommended radio (current), and still experienced them. Signal is better, and oddly enough voice doesn't get lost. Phone doesn't show that there is no signal, in fact it is at 3 bars on H.
Edit: I use a regional carrier, that doesn't list APN settings. By leaving APN type blank, I seemed to have solved the problem. Also dramatically increased the signal strength (Using Network Signal app).

Have you tried toggling airplane mode, or a reboot?

yea many times its very frustrating, i am currently in CM9 Alpha 3 and it happened this morning while i was omw to work

I haven't met this kind of case.are you sure that you are right?

yea dont take it wrong but im not a noob when it comes to this its just weird, its been happening for a while now in what ever custom rom i flash

So call Sprint tech support and have them try some steps of their own.

Dont mean to be an ass but what do you think they would solve over the phone, a Factory Reset, update my Profile and PRL, Airplane mode, ive tried all of that

I would flash a modem again, as this did fix my problem when I flashed CM9 and lost data and calls. You won't lose nothing by trying, good luck

Maybe the tower is down? Maybe they will refresh the data from their end? Customer care CAN do some nice things in trouble shooting. Use ODIN to go back to a 100% stock tar and see if it works then!

... please delete...

The issue you are experiencing happen over in the Boston area probably about 4 months ago give or take. So don't panic like I did. I had given up back then, unrooted, and took the phone back into the store telling them my wimax stop working only to find out that all of their phones are going thru the same issue. I would check with the sprint store or ask some one in your area if they are experiencing the same issue.

Me too..

I know this is an old thread but I just got the phone (used) and am having the same problem. It's *stock* JB GB27 (rooted or not) and I have not been able to get any data over 4g even if Wimax says its connected, with an IP address, Gateway, DNS address and says it's active on Sprint. And in a strong WIMAX coverage location. Ping says "host unreachable".
As soon as I turn off 4G, 3G takes over and all is good. To the OP, did you ever discover the cause?
Thanks in Advance.

Wimax sucks even when it is working. Sprint really isnt supporting wimax any longer. What is out there is all you are going to get. If you get it, great good for you. If not, oh well...

That's kinda how I look at it too but I might take up the challenge to try to resolve it or play around with some custom roms now that I am rooted. Maybe go back to Gingerbread and see what happens. I actually liked Gingerbread's app drawer better.

You can try running a more updated rom, such as cm10.1 or gb27. Stay away from any 4.3 rom though, since 4g isn't supported.:good:

Thanks for the responses, so I found something odd when this happens,
I wrote down the stats the phone gave me about my connection, IP,
Gateway and DNS server. Everything checks out as belonging to sprint,
EXCEPT my IP 6.6.2.142. Well, that IP just happens to belong to the
pool of IPs allocated to the US Department of Defense Network!
(checked on a whois server)
NetRange: 6.0.0.0 - 6.255.255.255
CIDR: 6.0.0.0/8

Is Sprint/Clear's servers possibly mis-assigning IPs???? This is from 2
totally different Wimax areas but I'm pretty sure that the same IP was
assigned to my phone both times.

Drop data issue on Galaxy Nexus

some people say drop data problem on Galaxy Nexus, it is related to radio/baseband issue, a lot of people recommend the following components
Radio/Baseband：
cwm-radio-i9250-xxla2 (latest radio from Google)
Kernel：
franco.Kernel-r158 (best kernel on market)
ROM：
aokp_maguro_build-35 (latest aokp rom)

Just go back to 4.0.2

Was at the Verizon store today and there floor model had no drop issues. Tried mine right next to it and it started to randomly drop. They are sending me a new one and are saying it will be here tomorrow hopefully I don't have the issue after the new one. The tech has a nexus and said he has no issues with his.

Came here to ask about this. Was wondering why it keeps happening. Was working fine when I was on stock 4.0.4 but since flashing aokp it happens all the time.

I had these issues with aokp and Franco kernel m3. Switched to revolution hd and James Bond kernel. Haven't had a single drop since.

I'm completely stock IMM76I, rooted and I sometimes get data drops.. this happens more frequently when I haven't rebooted my phone for several days. Sometimes the signal letter (H) disappears completely until I turn airplane mode on/off. Other times I see H but there is no data, only a reboot fixes it.
I'm using Tasker to auto-reboot the phone every day at 5AM, but this is gettig really annoying. I wasn't having any issues prior to that IMM76I OTA.

Noticed this was happening only when I was commuting on the highway, my phone loses data connectivity (albeit still showing 'H') and never gets it back until I reboot.
I'll try the set 700MHZ method and report back. But will increasing the min CPU from 350 to 700 hurt battery life a lot?

Based on my exp, you don't lose much battery life. I accidentally left the CPU at minimum 691 MHz and got similar battery life with 307 MHz as my minimum.

I just noticed I'm on the 4.0.1 bootloader. I'll flash the 4.0.4 one when I get home to see if I can finally get rid of this issue.
I tried flashing radios and RILs and it really hasn't helped...

I had similar issues though mine were mostly when leaving a wifi area my phone would not grab my cell data until I toggled airplane mode on then back off. Later I found out about GetRIL and discovered that most ROMs (due to being based on 4.0.4) have the XXLA02 RIL (Radio Interface Layer) while I was running the UGLC1 radio. GetRIL checks for you and allows you to flash the proper RIL (if rooted with busybox). I flashed the matching UGLC1 RIL and havent had a drop since

the suggested bootloader is the PRIMELA03..that page have just a typo (i asked to jbq and he confirmed the typo, he will update in future that page)
and EVERYONE have the correct PRIMELA03 bootloader
the signal issue is related to some bugs in the 4.0.4 roms
it happens randomly for some people in some network conditions..is like the phone is not able to get the data network...no way to solve this until a next update from google
the people that said "i solved by changing radio/rom/etc", just didnt test long enough to get the same problem again
if u (and of course lot of other people) don't have any network problem, then u are lucky living in a place where the network and ur operator are perfect...end of story
i'm not pessimistic, this phone is perfect, but will be really perfect when they will fix this...i had other android phones before this, and none had this problems...i know everything about radios, apn, networks..but there is nothing i can do to make it working fine ALWAYS..sometimes the mobile network works, sometime there is no way, even after a reboot, only moving temporarly to a different area solve the problem sometimes, even if signal was full bar

As per my previous post I didnt change my Radio but rather matched my Radio to my RIL (Radio Interface Layer). My phone hasnt dropped data in the longest time since I've owned it and shows no signs of ever dropping it (unless of course I lose signal ).

This question has been asked way too many times. I say the same response because it helps people solve this problem. The bootloader and radio configuration needs to be correct at least as a starting point and first step in trouble shooting. you assume everyone has the correct bootloader and radio, now that is just presumptuous. I'm so happy that you know "everything" about radios bootloaders and apns that is righteous! your post was very helpful, a great help thanks so much.

i'm not pessimistic, this phone is perfect, but will be really perfect when they will fix this...i had other android phones before this, and none had this problems...i know everything about radios, apn, networks..but there is nothing i can do to make it working fine ALWAYS..sometimes the mobile network works, sometime there is no way, even after a reboot, only moving temporarly to a different area solve the problem sometimes, even if signal was full bar

This is actually not true. I was on 4.0.4 but had the 4.0.1 bootloader somehow.
I haven't had a single data drop since flashing the new bootloader with XXLA02. The real test will be tomorrow, when I take my phone into work (big metal building). If I get no data drops at all tomorrow, problem fixed.

Can't Send SMS; Can Receive SMS/MMS & Send MMS

Hey guys,
I think I've reached the point where it's time to call in the cavalry and see if anyone around here is having the same issue; there appears to be a plague going around on the Verizon network, specifically in the Pennsylvania area, preventing people from sending SMS, but still receiving fine (and 4G works fine too, for the record). MMS still sends / receives fine, but I'm unable to send SMS. There are tricks to allowing a single SMS message to go through which involves toggling Airplane mode on / off every. Single. Time. People have also had success with turning 4G off completely, using the CDMA band after a reboot at which point they can send *several*, but still end up with the same issue.
The only solution I've read about that FIXED it is by reverting back to complete stock from VZW. Performing factory resets, using other ROMs, etc etc...doesn't work. I'd REALLY rather not do this and, frankly, would rather use 3G / toggle Airplane mode for texts than use Sense and get off of my ROM (http://forum.xda-developers.com/showthread.php?t=2560831).
People from other device forums on XDA are having the same problem; the ones I've seen that are active discussions are the Samsung Galaxy S III & IV. They're mostly CM ROMs *as well as* AOSP ROMs in general.

SIM card replacements are a no-go, and the recorded instances seem to be in the 717 / 570 area codes, mostly. Now I DO know that VZW released an OTA update for the One recently, and I'm relatively confident that would fix the issue, but I've no idea why. I'm thinking perhaps they dispatched new radios? I looked around a bit and couldn't find any flashable zips of radios extracted from the latest OTA, that's the next step I'll be trying once that download finishes.
So is anyone else having this issue? Any word on fixes?

The newest firmware from the latest OTA can be found in the 2nd post in this thread: http://forum.xda-developers.com/showthread.php?t=2485319
If you've already flashed the latest firmware then I'm not sure what to tell you... maybe ask your favorite rom developer to take a look at the latest OTA in regards to this issue?

If it has the stock rom and OTA update why not take it to the store and let them look at it. Something might be wrong with your account.

Those area codes for all phones on aosp roms are not working right now. Since 2/20/14. Has nothing to do with HTC or their firmware. I'ts a bizarre Verizon 4G issue. I am in the 717 area code with a Note 2 with the issue. I have seen others with S4 and S3. Verizon is aware of the issue and is working with another XDA member to fix it. To date it's not resolved.

Thanks DreamFX; I've been following this thread (http://forum.xda-developers.com/showthread.php?t=2658572&page=6) lately as they seem to be the most on top of it. I can't believe Verizon has let this issue go on for so long, but given that it seems to only be relevant to those of us with AOSP ROM's, I guess it makes sense. At least I'm still able to send texts, if not only through a silly process of toggling airplane mode on / off. Hopefully it gets resolved soon...

I'm getting this too, just started for me today from what I can tell. Driving me bonkers but, Airplane mode toggle totally works for me. :cyclops:
VZW SGS4 running AOSPA with 804 area code operating in Oregon.

Whoa, that's weird. I really thought it was isolated to the 717 area code. It's getting pretty crazy...I've been dealing with this for a few weeks now and my patience is running thin. Unfortunately it's not like we can just report this to VZW because all anyone would tell us to do is "restore to factory", which simply isn't a solution.

Yup, I thought so too. Just cropped up between 10a and 11a PDT. Like you said MMS is fine, simply affects SMS. And yes, restoring stock is simply not an option. Going to TMobile, however, is totally an option that I'm considering more and more often......
EDIT: AND SMS began sending properly (without workaround) for me around 8p PDT last night, just tested and still ok. RESOLVED!
EDIT EDIT: Issue now persists....sadface =[

IM getting it now. but not exactly the same. phone freezes without warning and I have to toggle airplane mode and restart to get it to unfreeze. this happened after the last OTA update. I am going to a custom ROM until I don't read anything about this for a while
