I have strange problem. When i use LTE I get full bars and everything works fine for a couple of minutes. Then I lose connection. I can not open any webpages, update Twitter or anything else. The bars are full and the 4G icon is there. If I run a couple of apps like LTE Discovery or Network Signal Strength, they both show that I am connected with good quality. But nothing on the internet works. I have checked the APN. It is correct.
If I deactivate cellular data and switch it on again, I have connection for a few minutes again.
If I set it to 3G only, everything is working fine.
I have tested my sim in my wife's iPhone and it works fine, no connection drops.
The phone has been laying around for a while. I just started using it again, but I can not get what could cause this behavior.
I am on Android 6.0.1.
Any ideas on what to try?
Possible loose connection inside the phone? Maybe a factory reset is needed? Is the phone being used with a case that could be interfering with the signal?

I flipped the back cover off and inspected the connectors. They are both seated. I am not using a case. Going to try a factory reset next.
But I don't see how a loose connector would behave like this, keep the connection for a few minutes and then drop? As I wrote I have full bars and both the apps I have tried show very good connection to LTE. Shouldn't a loose connector then show zero?
I believe those are wifi wires.
Is the imei properly displayed in the dialler?
Maybe re-flash the latest stock ROM in fastboot?

Yes, correct IMEI.
Did a full factory reset, but seeing the same. I have got full bars and a 4G symbol with no exclamation mark. I have connection for a couple of minutes and then it drops. Switching to 3G only makes the problem go away.
Going to try a re-flash, but I have never rooted this phone, and I am on original rom.
I see that there are two antenna cables, one white and one black on each side of the battery. Does anyone know which is which? Does 3G and 4G share the same cable?

I am at a completely loss with this. I have searched and I have found a lot of threads on several forums with a similar problem. In fact the problem with intermittent loss of connection seem to go back to the 5.0.1 days.
I have tried everything I can think of, but still I have 4G for just some minutes, then it drops. If I wait another few minutes the exclamation mark shows up next to the 4G symbol. Every "network checking" app I have tried shows I am connected to LTE. In the phones "about"-menu and sim information, it also shows connected. But it's not.
Toggle Airplane mode on/off solves the problem, until it drops again after a few minutes. If I try speedtest I get full LTE-speed before the connection drops. I haven't timed it, but it almost seem to keep the connection for exactly the same time everytime.
This has to be a software bug of some kind, but what can it be??

No, I have not. I will try that as well. Have to look around a bit to find out how.
Yesterday I rooted the phone and installed the latest Ressurection rom. I suppose that came with a new radio module? But the problem remains even there. I am starting to believe that this could be a hardware issue after all. I have ordered two new antenna cables and will replace them. But I don't understand how a faulty antenna wire could cause such an error. As said, it keeps the connection on LTE for a couple of minutes. Switching Airplane mode on/off fixes it for another couple of minutes. If I switch to another apn and back again the LTE also wakes up again for a brief time.
Switching to 3G only works fine all the time. 2G and Wi-Fi also.
And just to know when it says that is connected to 4g is it really connected? Have u tested the speed?

Yes, it is connected. I ran a speed test and got full speed up and down. But after 3-4 minutes, the connection drops.

Indeed!
It looks a lot like this:
https://productforums.google.com/forum/#!topic/nexus/o-UyGECxh2k
But having read the thread through, there doesn't seem to be an absolute answer to what is going on.
Tried downgrading the modem to the modem from 5.1.1. No change. Have LTE for 3-4 minutes, then it drops. Shows full bars, but there is no connection. After another couple of minutes the exclamation mark comes next to the 4G symbol. Toggling Airplane Mode on/off gets it going again for another couple of minutes. It drops even if I am using the phone.
Changing to 3G only, works fine.
I have ordered new antenna cables, both the black and the white, and will try to replace those. I don't have much faith in that, due to the nature of this problem. A broken antenna cable should not work for 3 minutes and then stop until reactivated by airplane mode. But, I have run out of things to try.

I am using Telenor in Norway. My wife has an iPhone 6 and I also have a Samsung Galaxy S4. They both work fine on 4G with my simcard.
I had a similar problem in new York. I have metro PCs which is owned by T-Mobile. Every where I checked they said my current APN was correct, but I still had the exclamation point. I ended up fixing it by changing my APN from fast.T-Mobile.com to metroocs. Have you compared the apns from a working phone to the nexus. It sounds more like an authentication problem rather then a signal problem. Or call your carrier.

So... the apn-settings are correct. They are the same as on the S4. I even tried a sim from another carrier now. It behaves exactly the same.
This has to be a hardware issue, even though I can not understand how it keeps the connection for a few minutes and then drops. Doesn't make sense at all.
I had a similar issue with Consumer Cellular (an AT&T MVNO in the US). When preferred network type LTE was selected, the Nexus 5 would go to “No signal” every 12 minutes for 45 seconds. This wasn’t an issue when preferred network type 3G was selected.
I was able to resolve it by modifying the APN slightly, changing the parameter “MVNO Type” to “GID”. I left the MVNO value field to its default value.
This issue started with Android 5.1 and I still need to set that parameter with 6.0.1. Experiment with that setting and see if it helps.

I tried that too today. No change.
But I have discovered something new. If I start streaming a radio station when I still have 4G, it keeps streaming. I left it on for an hour and it kept the connection the whole time. I stopped streaming and started surfing + facebook and it kept the connection.
When I toggle airplane mode off/on or reboot the phone it keeps the connection for a few minutes and then drops. Like before.
Now, this HAS to be a software error of some kind. It almost seems like the 4G radio goes to sleep after a few minutes and then it doesn't wake up again. If I switch to a different apn and back again, it wakes up.
I have made sure that the apn settings are correct. My carrier has confirmed that, and they are exactly the same on my S4, which works fine.
Does this make sense to anyone? What more can I try? Is it possible for the 4G radio to go to sleep and stay off?
Edit: Keep trying new things, and I have discovered that if I connect the charger when the connection is "alive", it keeps the connection. When I disconnect it, the connection drops after some minutes. This strengthens my theory about the 4G radio going to sleep.

Received my 32GB Nexus 5 the other day and thought it was broke as I wasn't getting any mobile data in the house at all.
I've finally worked out that this seems to be an issue with the Home Signal Box that plugs into my broadband connection as I need one due to having no signal at all downstairs and a very weak signal upstairs.
The Nexus 5 connects to the box fine and I get full signal but no H on phone at all. If I want data I have to switch wifi on.
This is the only time I've ever seen this and i've tried my sim card in quite a few phones and in every other phone apart from this Nexus 5 I get both calls and data fine.
Does anyone else have both a Nexus 5 and Home Signal box and getting this issue?

I had a similar problem with my iPhone 5. Data didn't work without Wi-Fi or at best, was patchy. Three even specify on their site that Wi-Fi should still be used for data.
I have noticed the exact same behaviour on my Nexus 5 with the Home Signal box. My Nexus 4 (now used by my wife), daughter's Samsung S4 and son's Sony Xperia Z all work with voice and data.
There is another symptom of the Nexus 5 and Home Signal box I have just noticed, it's killing my battery! The Phone application is continuously causing a wakelock when the Nexus 5 is connected to the Home Signal box, if I unplug the Home Signal the wakelock stops and battery lasts a lot longer.
Hope Three are aware of this and can provide a fix.
I left a message on the 3 facebook site and their response was just to switch my wifi on when I'm in house. Well I do that whenever I intend to use any amount of data but when my phone is just sat there waiting for something to do i'd prefer it to be only using battery on phone signal and not wireless as well.
I've devised a workaround using Tasker to switch on Wi-Fi and switch off Mobile Data while at home and vice versa when I leave. Battery life is back to normal. Phone app isn't even showing on battery usage screen and having Wi-Fi on all the time I'm at home isn't using as much battery as the Phone app was with Mobile Data on even though there was no data connection. I think the problem is that the Home Signal box is not allowing the phone to establish a data connection and the Phone app continuously keeps trying thus running the battery down. I'll work with this for now but I do hope Three come up with a fix.
My Nexus 5 arrived today, seems to be working happily with our Home Signal box. Weird. Potential defect or something?

So you turn your mobile data off in the house too? Because the WiFi battery use replaces the mobile data battery use... and should actually use less.
Voice Radio uses batttery, then mobile data uses further battery on top of that. So unless you're turning off mobile data completely, you should find that WiFi on all the time is a better solution.
This isn't really relevant to the thread though, so sorry about that.

I'm having the same issue with a white Nexus 5, Baseband version M8974A-1.0.25.0.17 and the 3UK black home signal box.
Feels like that whilst 'Data enabled' is ticked in 'Mobile network settings', the phone keeps reattempting the data connection, even though i have WiFi enabled.. ??
The same SIM does NOT have any issue in my GalaxyNexus.
1st and 3rd line tech support at 3UK have confirmed that data is getting though the SIM thus the handset itself is seemingly the issue. 3UK are recommending that I take this up with Google...
Same problem here, N5 + Black Home Signal = No data. Works fine on my other phones and iPad. Also when used with a Vodafone Sure Signal my Nexus gets data fine.

This is not usually the case (edit: In my experience). Unless the Nexus 5 has some special radio hardware I am not yet aware of? The additional fluctuation in signal strength makes that even less true IMO
There are arguments on both sides of the fence if you google it, but I sit on the "WiFi is better" side.

Just install JuiceDefender and it sorts this out for you, or seems to for me anyway. It disables data if you have a wifi connection i.e. whilst you are in the house. Upshot is good battery life and I don't need to do anything to the phone - juicedefender does it for you.

Ah ok. I stand corrected. I have no experience of that. I took your comment generally
Has anyone spoken to Three about this since?
This is very annoying.
I just sent my Nexus 5 back and got a Note 3, I'd prefer the Nexus 5 though. If its fixed I might get another one. My home signal box hasn't worked since yesterday either so no signal in my house
Seems to be fixed now. I am now getting a data connection through my Home Signal box. I have not changed anything on my Nexus 5 so can only assume that Three have made some change in the background to how the Home Signal works with the Nexus 5.
I have a problem with my Nexus 5 that i would like some help to troubleshoot.
When I'm on cellular network i often have full reception on 4g, when suddenly it drops to absolute zero all of the sudden, data is disconnected and no phone calls can be made during that time. If i wait 10-15sec it is connecting again and up to full strength.
This happens all the time with a few minutes between each time, and has no affect of the location I'm at.
Often I'm just surfing the web when it comes up that this requires internet connection, and notices the bars are gone, and have to wait a few seconds before its back online again.
What would be the best steps to troubleshoot this? Is there any radio log on the phone that i can tail for errors?
Can it be hardware error? Can it be that the simcard looses connection to the hardware?
Im currently running a custom rom, but it was the same with stock when i tried that.
Any help appreciated!

Does it do it on other phoness? I've found that my carrier is updating towers in my area. When T-Mobile US was upgrading their network to LTE and changing panels, literally signal that was once there would be gone for upwards of a week.

No i had a Nexus 4 just before, using the same rom and Provider, worked fine then. Have had this issue for about 1,5 month.

I'm having exactly the same issue. Though for me it's not happening all the time, only when I'm connected to VPN. It's still very annoying because VPN disconnects when the signal drops.

The WiFi and Cellular signal issue is gone!! New update is great.
I have not noticed that. I leave my Wi-Fi on and connects when home without issue. I've check cell signal levels regularly on new phones. My first impression with this phone is that the cell reception is excellent.

I've noticed that a couple times as well. I assumed it was my SIM card as I changed carriers the same time I got this phone. It's not a deal breaker for me as I actually don't use the phone for calls much anyway. But yeah, it needs to be fixed. Just waiting for the next update.
Great, i thought maybe it was her phone in particular. I mean, I accepted the current update thinking that would solve the issue, but it didn't. Same story.....when wifi is on, the cellular signal turns off, on, off, on....maybe within 5 second intervals. Im shocked many people haven't complained about this.
if it wasn't for your response I was going to return the phone back to Amazon and exchange it for another one.
other than that I think the phone is excellent for the money and since my wife really isn't into development and rooting, for her this is the perfect replacement for her defective S4. however I would still like to be able to install a custom recovery at least.
My issue isn't anywhere near as bad as yours I would say. If yours is turning on and off a lot them you may want to replace it. I notice mine turns off once a day for a few seconds but I'm sure it does it more and I just don't see it.

I've used my phone to tether a few times and noticed the cell signal drops now and again....there is an app but I can't remember the name..something like "connection stabalizer" that toggles airplane mode on and off when it detects a dead connection....it might do the trick.
I have never experienced any of my previous phones do that, so i will most likely be sending it back for an exchange from Amazon.

I have never experienced this either. Have you tried a factory reset yet? I may try that in a couple of days and see what that does for me.
Well see, before i took the latest update the problem existed.........then, after the latest update the issue still exists. So i don't think a factory reset will do it but i will before i actually mail it out.
I reset the phopne and installed a mobile network detect app that notifies me when the signal drops. we'll see what happens.
I have no job so I have the time to blow
I am having the same problem. I am losing the signal repeatedly. It goes to no service then comes on to two or three bars even when I am in the exact same location.
So far so good. 6 hours later and no signal loss yet. On another note, the reset fixed an issue I forgot to mention. when downloading from the play store the download would start and immediately get stuck at 66kb. I would have to start and stop the download two to five times before the app actually downloaded. I just finished installing all my apps without an issue.

Mostly. Wi-Fi was off about 6 hours while I was sleeping. I'm using Network Signal Info Pro to tell me when I lose signal. I know it works cuz I turn on airplane mode and it notified me. I carry the phone around the house so I don't miss a notification. So far in 33 hours still no signal loss.
Hello,
I have a big problem with my OnePlus One: After it detects the SIM and I entered the PIN the phone isn't getting any reception. I tried multiple SIM cards. I am actually having a IMEI, tried all APNs, which are available by the providers and I even tried multiple ROMs (I have no problem with erasing data or so, 'cause it's my backup OPO)
But in each single ROM the One isn't getting a signal.
In the settings I can actually choose the providers so the chip/ module ist working (maybe interesting to know: I repaired the phone's screen, so of course i fully dissembled the phone and first i thought maybe I cracked some parts, but the motherboard of my normal OPO is working fine and gets reception WITH all of the parts from the backup phone. In the other way the "not working" motherboard is also not receiving reception with the normally perfect working parts.
So there are only two ways:
Some software isn't working perfect, especially the modems' one, because I can't connect to any network. (I already typed in "+#+#4636#+#+ to see if the phone is getting a signal and yes it does!)
OR some components of the chip on the motherboard broke by the repair, but because it is getting a signal this isn't this way I think.
So I am over. Do you have any hints like a special modem that I can flash?

My problem is that I'm not even getting a signal in the notification bar. I am only getting a signal in the hidden menu (call *#*#4636#*#*)
A change between 2g/ 3g and LTE hadn't changed anything and a swap with the frequency via the hidden menu also didn't changed anything.

Worst case scenario, IMO, is that your antenna connector has broken itself from the board at the trace level.

They said the only thing that they can do is to "repair it", so they will replace it, but it would cost so much...

No. It happend a week or two ago. I started my phone in the morning and there were 2 problems: The touchscreen didn't reacted to anytging, but the LCD was working and the signal icon in the notfication bar didn't showed anything. (I didn't use a pin with the SIM)
So I restarted the phone with a long press (about 10 seconds) on the power button.
Nothing has changed so I thought that the cables where loose or so.
I took it apart and disconnected every single connection inside. Put it all together then. Touchscreen was working again, but nothing has changed by the signal.
So as I already wrote:
So I swapped the motherboard with my other OPO and it happend.
So the antenna and bottom part is working.

Check the connection of network antenna again.It might be loose.
Problem solved. It were some "not perfectly working SIM cards" as my provider wrote me in a letter, which came with some brand new SIMs, which are working fine right know. Don't' know why they were all working in the other OPO, but now the problem is solved!
Thanks for any suggestions!

I'd still check it physically. I practically tore my hair out for a few hours after receiving a friend's phone after having its screen replaced. Similar symptoms wherein you can ping for networks, there appears to be signal from the debug menu as well but it just wouldn't connect to a network. I suspect that once it tries to connect and sends the required voltage to do it it fails as the antenna isn't there. The board and the connector itself is a bit of antenna on its own + you may be in an area that has very good reception in general.
Hello,
I have a problem with my OPO that has been going on for months now (I suspect it's hardware based? but not sure)
My opo can always connect to 2g network
My opo can only connect for a limited time to 3G/4G networks. If i change the network type, I get internet alright for about an hour or so. After some time or event (can't find a pattern), the phone is suddenly disconnected from mobile internet (even though data is ON), but my reception indicator is full. I also cannot place calls or get called: when I try calling, I get either a textbox "network unavailable" or the call attempt just ends on it's own without result. I'll call this state "fake 4g"
Here's what I have already tried:
-reboot, flash other rom, factory reset
-downgrade and upgrade TWRP back again
-messing around with 4636 (but i think i haven't tried switching to US band and back to EU - i'm from europe). Note: the interface shows precisely one cell tower when i'm connected to fake 4g
-going back full stock (flashing a version of cm prior to YOGPAS1N0) in order to update the radio. I even installed oxygen at some point
-pulling a logcat. However, this problem (other than the fact that i have only have a basic grasp of IT) is that I cannot exactly pinpoint WHEN fake 4g occurred without looking at the screen/placing a call. I managed to determine fake 4g came up between 4:55 and 5:46, which is still a heck of a logcat. In order to generate some logcat chatter, i've placed a few unsuccessful calls during fake 4g period (i've pinpointed those logs)
Does anyone have any idea as to the cause of this bug (not entirely sure it's hardware based because it works, well, sometimes...)? Or can anyone maybe tell me what to look for in that 50 minute logcat? I guess I can always have another logcat run in the weekend and check every 5 mins until i can spot fake 4g happening.
Note: I haven't opened it to check whether the antenna is plugged or anything (not that i would see much, i think). Anyway, i can always do it if need be.
Thanks in advance
I have been having a similar problem, the LTE range keeps fluctuating from zero to 3/4th to full from time to time, even when the phone is lying stable. Range appears well when on 3g. It isn't sim card based as iv'e tried various sim ,phone combinations.
Also i have noticed many topics appearing in the past few months regarding network issues ... some kind of a pattern ?
Ah yeah I forgot to mention that I tried the simswap trick too, to no avail.
So you're suggesting the hardware antenna might be of poor quality, that might be the case. If so, I suppose the antenna cannot be easily changed (ie incorporated in mobo or whatever).
Does anyone know whether antennae are prone to fail in general?

Nope.If there hasn't been anything that could damage the hardware,no.
Have you tried changing firmwares?
https://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-t3462214
Even i am facing the similar kind of problem and posted my question here https://forum.xda-developers.com/oneplus-one/help/internet-issues-intermittently-unable-t3714911. One more thing to note is if you try tethering with laptop the internet works just fine (it happens with my device) . Even i have tried many combination with 4636 interface but i really can't understand the reason behind it.
Flash latest modem firmware... Then *#*#4636#*#* ..then on phone change signal to 3g only or LTE only..
Helped me from losing signal
