I have been experiencing data issues after rooting my device. The signal bar never seems to fill all the way since rooting. Before root I would have pretty consistent LTE. I still have a data connection, however it isn't nearly as it was before. Also, next to the signal bar I've noticed an "!" every now and then, I've tried searching for what this might mean, others have experienced it, but there were no answers. I am on Verizon, my SIM Status states I am on the network,
Network type is CDMA - 1xRTT
Baseband version is: MDM9625_104446.01.02.101R
Building # is LMY47Z white/64
I had read some where on this forum about flashing different radios. I've never attempted to do so. I'm fairly new to rooting, this is my second phone I've rooted my self. So feel free to use Crayons when explaining. The only thing I've done outside of the root was enable WIFI tethering through the system/build.prop.
Thanks for any help
Well rooting alone will not affect your data. You must have done something else to affect it

I wasn't sure if maybe the recovery I used might of had an old radio of some sort, not really sure. I used TWRP if that matters. Like I said the only other thing I edited was the Build.prop with "net.tethering.noprovisioning=true"

if you messed up on the spelling in the build.prop method, you wouldnt be able to boot. twrp recovery does not have a radio, and is the only recovery for the n6. and rooting doesnt touch your radio, all root does is give you administative permissions. as a fact, since you still get a radio signal, even though crappy, its still a signal and nothing is wrong with your device. the only issue that you seem to be having is with your provider. do you live deep in the country? i know that with tmobile, thats where bad signals are, and some report the same issue as your having.
I get weird signal lte bars, but that's not indicative of call signal right? I am on cricket aka AT&T, using in central metro area, it tends to flux. Where as Nexus 5 and LG G3 seemingly had better signal (going by bars).
EDIT: have you tried checking your Settings>Battery>Cell Standby? What's you "time without a signal"? Today I got 3%, previously it was 10%, but I'm going in and out of buildings/elevators.
Well after a couple days I've been checking the Cell Standby like you mentioned. Its around 10%. When I'm at work its about 60%, but that's because I work in a controlled area that blocks most cell signals. My connection seems to be getting better, I can stream Netflix and other things on without much problems. I had my phone for a little bit before I rooted, and I never got the "!" next to my signal bar. I guess the "!" means it is searching for a data signal. I get it at least 3 times a day. I do live in a rural area, I wouldn't call it back woods. I'm about 30 min from the capital. but everything is settling out,
thanks for the replies!

Hi guys,
Since yesterday morning my phone has been on G (edge/gprs) only instead of 3G (hsdpa) like it was almost always before. I'm on voda uk with good 3g signals in London and phone is showing -51 to -65 dBm (22-31 asu) which i think is good.
Also my wifi that always worked is also not connecting anymore...what gives? Regarding wifi i mean it connects but home page doesn't load any more on constantly refreshing even once. It does on my laptop on same wifi signal.
I have just updated normal apps like handcent sms/linda manager etc. since yesterday and restarted phone many times and done nothing drastic...so why these data problems all of a sudden?? Thanks
Carrier: Vodafone UK
Country / Language: English (UK)
OS / Browser / build number (if applicable): update 1 - stock rom
Tried soft reset by pulling out battery...on restart phone showed 3g for a second before wifi kicked in...still no page load...after switching off wifi it again went to G only!! Damn I don't wanna have to lose and reinstall all data/apps!! This so irritating..I love this fone and this is how it treats me!
Lunacy!
Now the fone automatically goes to 3G UMTS/HSDPA (wifi off) but with atrocious signal strengths of 0 dBm or -111 dBm with 1 or no bars!!!
I always get awesome signals in my room arnd -55 to -69 dBm and all 4 bars so what the hell is going on!!
Is this vodafone's issues or my N1 is dying slowly!?
Back to G n no wifi use!
Any help anyone?? please!
Not sure how to help you, but I thought I'd mention this if it's at all related:
my phone has twice now shown that it's on Edge connection, but run at 3G speeds. Not sure what the bug is but I ran a speedtest and was able to stream Pandora and browse the web without any trouble.
thanks for that but i'd sure love to see some pro's to help me out!
sounds like a carrier issue... however if you are rooted, try reflashing your radio and see if that helps and you may want to try each radio out as well
wifi is working today with full signal but on mobila data it stays on G with full signal but 3G sometimes with 1 bar or no signal...wtf!

When was the last time everything worked correctly? What have you do with your phone since then (different rom, different radio flash, new mods that alter system files, etc)? Have you tried calling your carrier to see if they are having problems in your region?
Nandroid backup, factory restore, reflsh cyanogen, test. If it works again you've got some bad setting stored. I can't help you find that setting but at least you've narrowed it down.
If this is affecting your wifi, then it's not a carrier issue. It's something with your phone.

2 days ago all was well. I just updated linda manager/handcent sms and 1-2 apps from market. I'm on stock rom so no radio etc. for me and I don't mess with system files and keep my phone clean by clearing caches etc. Thanks anyway.

Do a factory reset or a full wipe through recovery. If that doesn't resolve the issue, then let us know.
Hi all,
Within the past week or so, I've noticed a fairly large drop in the signal strength from both my wireless lan and 3g signals. With the cell signal, it was even dropping to edge sometimes when I was outside in an area which used to give me full bars. Wireless isn't much better, and it seems to be fluctuating between 4/5 signal and 2/5 signal even though I'm close to my router. Again, I used to have full signal in the same location. Nothing really would have changed.
Yesterday I tried flashing Continuum (2.3.4) instead of running the stock 2.2 that I had before. The 3g signal seems to be *slightly* more consistent, although I'm still not at full bars, whereas I always was before.
Is this a common occurrence? Is it my hardware, and can I fix it myself, or do I need to send it in to Rogers? I've only had the phone for about 6 months now. I wonder if it's under warranty still (assuming I flash back the original ROM and bootloader).
If anyone has any suggestions it would be much appreciated. It's odd, but the wifi signal almost gets boosted when I'm trying to use the internet, but not to full bars even when I'm near the router.
Bump. Is this the wrong place to ask this question?
Cheers
My AT&T Captivate has similar issues. Mine started about a month ago. I haven't put any effort into figuring out the root cause.
Yeah, I'd really like to figure out what's up though. Does the hardware just crap out after a few months of use? Thanks samsung!

This trend happened with my HTC Aria as well. I don't believe its anything related to Samsung hardware crapping out.
So, if it's software, what would be consistent across a ROM and kernel flash?
I recently fixed a network error effecting call quality by flashing a new modem. I know our issues are different, but since you did flash new ROM i dont think it could hurt.

Unfortunately it's not just my wifi that has issues, but 3g as well.

Have you tried flashing a different modem? The one that came with your current rom may be different than you had before which would account for your weaker signals. Different modems work better in different areas. Try something else and see if it doesn't help, such as JK4 or JL3.
I haven't yet, but I actually had the problem before I flashed the ROM.
Where are you located. I have absolutely ATROCIOUS reception in Atlanta, and ATT says they have some 50 towers down. Your area might be the same. In my basement where I used to have 3 bars consistently, i know have to run around the basement struggling to get one bar to send a text. ATT needs to get their act together or everyone might start switching to Verizon.
In Toronto, Canada. We usually have good reception. It's only recently that I have had issues.
check with other people such as your family and see if they have bad service too, if so call your service provider, there may be an issue on their end. Other than that all I can suggest would be a full reset to factory and a master clear and then restart from there. While that is annoying, it might be worth it to solve the problem.
I recently flashed the (Unofficial) PAC Man ROM over night, and noticed my signal bars were blank. I have 4G (It says sometimes) but when I check my signal strength, it's 0 dBm 99 asu. It can see my Network, says I'm in service, and gives me my IMEI number. However, my phone number is unknown. I'll upload screenshots, and will answer questions (Obviously) if need be. (Note: I can't post in the dev forms, as I don't have enough posts, thought I have PM'd Skeevy about the bug. ROM runs fine otherwise ) Thanks in advance.
Well it's noted as a known bug in almost all 4.2 roms so...

Hm. Read the PACMAN rom bug list and it didn't show up and that's what I'm using.. Oh well. 3G works, I get signal, but my phone number doesn't show up, so eh. I can live with it I guess,
I am one of those folks that will keep flashing for latest stuff cause I like the bleeding edge...
I did have a problem today that all my roms I flashed to had no service. No matter what I did... No bars and WIFI couldn't even be turned on.
End result fix was to flash back to ATT stock US rom through RSD. Then putting CWM back through fastboot and then my customs worked fine. I'm sure it was something dumb I did that caused it, but with an unlocked bootloader, I have no fear of trying anything

Honestly, I think it has something to do with the way 4G LTE is encoded with the ROM. I've flashed stock, gone back and installed CWM and re-flashed PAC and still had the issue. But It still works, I just don't get signal bars, with 0bdm and 99ASU all the time so yeah. 3G and HSPA+ work flawlessly. If I have HSPA+ and 3G I'm fine lol.
Now that GPS is pretty much figured out, which is what I've been focused on, I'll start looking at the stock build.prop and and compare it to PAC's. Should give me some insight to the 4g issues.
I wasn't aware that all 4.2 roms had the signal issue. I see it on PAC maybe once a day and its gone within 5 minutes. I'm not 100% positive, but I think it has to do with wifi. When ever I notice a wifi issue like it not connecting as fast as it should, sure enough the grey icons follow.
Went to Taco Bell last night, saw their wifi connection but didn't connect. Got home, home wifi was slow to connect and they grays. Makes me wonder if there's an issue with the wifi queue or the phones "which internet do I use?" queue.
//Was in drive thru line for a while for 3 Beefy Crunch Burritos...in the store, the guy upfront of me in queue had an 18 item order. Looked like he was leaving the grocery store with all those Bell bags. I thought, dang, his gut's gonna like him in the morning.

Last line made me LOL.
The issue just seems to be 4G and LTE. WiFI on your PAC rom seems runs wifi great, but sometimes it disconnects (very rare for me, but I think it's for everyone in my house, we have quite a few WiFi hogs, lol). I'll just keep flashing your new roms as they come out, and hopefully it'll be fixed. Not to big of a deal if it isn't lol.
signal strength
Did you compare signal rating from your stock ROM to custom ROM?

If you have an older router, try changing the WiFi frequency from auto to 2.4ghz -- fixed my WiFi disconnect issues right up. Also, if that doesn't, then set up a static IP for your phone since, in my experience, static connects a lot faster. That's not really a bug as it is a hardware issue (an I can't afford a new router issue).
As for signal. Can't test LTE\4G. Not available in my town. 3G works fine and doesn't have any disconnect or signal issues. I can suggest to try different modems from the various fastboots.
Its just that the custom Roms don't "see" the 4g signal is all... So it gives a no signal bar. Its different from the connected bars and fully connected bars that still show signals.

I'm having major trouble lately with my turbo switching from 4G LTE to 1x, 3G, or even no signal or data signal at all. It seems to happen more when it hits 15% and the battery saver comes on. But when I turn battery saver off or hook it up to a charger it doesn't connect back up or do anything. I'm getting really frustrated by this because I cant seem to get my phone to re connect to 4G no matter what I do. I put it in airplane mode and even restart my phone; it wont work no matter what. I think its mostly because of the update to lollipop and its a glitch. I was wondering if anyone else is having this issue and if there's any way to fix it besides sitting there for a half an hour wiping the cache and not being able to use the phone.
I'm not experiencing that. Did it start right after you updated? Have you done a factory data reset since upgrading to the pop? Onethng you could try is going into setting and switching it from the factory global mode to 3G/4g and see if that helps. I haven't ever needed to with the turbo but others have and successfully avaoided doing an FDR. Lemme know if that works. We'll get this figured out.
Well I came from a rooted 4.4.4 so I had to reset it back to the original in rooted 4.4.4 in order to update. So technicly yes I did do a factory reset since the update. No I haven't had any trouble since the update until recently for some reason. I've got a signal booster at my house and wondering if my phone isn't trying to switch between the booster and the actual tower, causing it to take more power which makes it loose connection because it can't decide which one to connect to. But I have perfect 4G signal with the booster so I don't see why it would want to switch.
I wouldn't imagine that it would be the booster since you're signal is solid there, but it could always be a possibility. Have you tried switching from global mode under network settings to CDMA/LTE? That solved all the network issues I used to have with my old Razr Max HD. Also, have you taken the OTA that was pushed yesterday? Some people were seeing an increase in signal strength.
As a matter of fact, I updated right after I posted that comment. I didn't even know there was a update till I was looking at Google now and saw there was a small update out. I havent had any issues with connection since the update. I'll post back here if I do come into problems. Thanks for the help though.
Any time buddy! I sincerely hope that solved the issue!
Well I was using navigation earlier today and for some reason, not only did I completely loose my 4G data but it said I lost GPS to. My maps app continued to run but it didn't look like I was moving on the screen, even though I was. Guess the glitched didnt get completely fixed.
It's almost like it does it just at night and when I'm using a lot of data over 4G.
Hi,
LG V40 isn't connecting to strong Cell or WiFi signals without a Re-Start ... why?
This has never been a problem before. It's always shown a strong Cell Signal at my house and I've fantastic WiFi speeds at the house too. However, occasionally I"ll notice the phone is slow to load a Website or takes too long to send a large file in a Text, I'll look at the Signal Strength and it shows low Cell Signal and low WiFi Signal, yet I know (and test) them both from another phone and they're as strong as possible.
What is the issue and how can I fix this problem?
Thank you all in advance.
Regards,
Gregory
Almost a week later and not one reply post ! ? !
Guess the heat for LG has faded ... not only for the brand, but for this phone, yet, this phone is still (somewhat) fast, takes all updates and is a good camera.
Well ... I still hope for an answer. I've done a complete Factory Reset without loading ANY apps at all for 3 days and it STILL has this issue.
(... Side Note: It's absolutely AMAZING how long the battery lasts when all the bloatware and junk apps are removed, all non-needed-undeleteable-apps are disabled and there's not one Third Party App ! ! )
I read on another thread it's only happened since 5G started getting activated on towers. I don't understand how one would affect the other, but maybe someone can chime in and clear the air on that.
If I don't get an answer soon, I'll have to check other phones to see if others are having this issue and upgrade to a newer phone.
Hope to hear from someone soon.

I don't have the exact same issue as you, but I have an issue where my data connection doesn't connect when my WiFi is off. So I need to turn on my WiFi before I turn on my data, then only turn off my WiFi. I didn't know this before, and I had to resort to turning on airplane mode, whenever I needed to use my data.
I sent my previous device in for warrany repairs, so my device has a new mainboard, and the issue was on both devices. It has to be a software issue on my variant (LG-V405EB), because I haven't seen any other complaints about it online.

Thanks for the reply Miz Pimp.
The phone was checked out and came back working 100% efficient - but they did say that clearing the phone with a Re-Start will help with connectivity.
I hate that as an answer - but it's something that a Samsung user said they've got to do too.
Feeling less alone regarding this problem, but I'm going to upgrade to a 5G phone early next year when that coverage is expected to get to my area.

That really is a horrible reply. It sucks that we need to do that to get a proper connection. I never had this issue with ANY of my mid-range Huawei devices, so it's pretty annoying that I'd have issues on a flagship.
The System Update 13 from Verizon just installed.
Still the same issue with connectivity damn it! !
I literally shut the phone off and restart to get better reception for several hours .... then the reception will drop to one or two bars, calls have drop-outs and upload/download speeds drop. A Re-Start and it all goes back to full bars and high connectivity speeds.
This does not happen to friends with Pixel's, Sammy's or iPhones.
Looks like the LG has some sort of malfunction ... OR ... it's a program to keep battery life exceptionally long, which it clearly does over my other friends phones who maintain high connectivity rates, yet significantly lower battery life.
