Wow, this is ridiculous and why is this happening?

Please help:
I'm on CM9 19 6 nightly. Using Semaphore kernel without any modifications to the scripts.
The problem: My signal keeps on going out at regular intervals.
I've used XXJVU, DDJV5, XXJVT, KF1(Nexus modem for ICS) and various more. I stay on the modems for a week and then change to another one. The latest one is DDJV5 which I have been using since the past 2 weeks.
Tried all of the modems I could lay my hands on. Nothing works.
But the moment I come to work, the signal keeps fluctuating over the day. Sometimes it would be out for 10-15 minutes. When it's back, it would get back to giving -65 .. -71 dBm. It would stay like that for a few minutes and then it would be gone again for another 10-15 minutes or so.
It has turned into an OCD where I keep checking my signal.
This does not happen when I'm back home and then I'm back to getting good signal.
Yes, this looks to you like a locational issue. I thought so too. BUT, how did I get so good signal till a week back at work?
Question: What could have made this mess to my signal reception? How can I solve this?
No, all my syncs are OFF. I keep my 3G turned off and only use it once an hour or so for a few minutes. I don't use any signal consuming apps.
Also, sometimes the 3G would work even without the signal.
Another thing, sometimes there's a (x) sign at the signal bar thing and sometimes there is no (x) without bars.
As a cure for the OCD, I've taken an off from work today just to get some rest from checking my signal every now and then. And maybe find a solution.
I'm on Vodafone India.
Indians, I am on Vodafone India in Pune, Hinjewadi Information Technology park. Maybe Pune guys can help me out too?

maybe the phone changes the network mode.. 2g 3g or i dont know , try to put in in 2g only mode , or gsm only mode.

When the signal bar shows with a "x" it means the network is not available...go to settings and change the Network mode to "GSM Only". It will solve the fluctuating issue but network speed will be limited to 2G only.

Thanks, let me try it out.
Where is the network changing option to GSM only in ICS?
Okay, I guess it's the 2G mode.

Is going to 2G mode my ONLY option?
How can I fix this and get back to using 3G?

Update:
Changing to 2G mode fixed the problem. BUT...
I have a few questions now:
I want to use 3G but at the same time I don't want the signal to fluctuate between 2G and 3G—want to get constant 3G connectivity without signal fluctuations. Is there any way I can fix that?
I remember reading somewhere that going to recovery and changing permission helps this.
Anyone knows how to change the permissions so the signal fluctuations stop?
I have done a lot of reading on XDA but I haven't noticed an issue like this.
CM9 guys, anything please...

I have the same issue mate...using 2G is the only option to get signal without any problem.
The problem doesnot lies on your phone but the problem is with the operator. The area where you live hardly 3G signal reaches there (same problem with me).
You got two options to fix this issue:
1. Change your Network Operator
Or
2. Settle to another location where 3G signal is fully available

Both the options look impossible for me at the moment.
I will start living with the hope that the operator brings us some decent 3G signal here.
Thanks a lot anyways. It was helpful. Hope others facing the issue can learn from this thread. :good:

Complain to your provider, very loud!

:gooditto the same problem occured to me on Vodafone (Chennai) tried all modems listed above nothing worked ...Used to lose signals all the time with 2g data on especially at my workplace intermittently for 3-4 months ever since I upgraded to ICS..Sometimes used to lose signal even if data was off..multiple reboots/restarts gave no solution ..issue persisted across all the 15+ roms i might have flashed over the past 6 months..
Finally fed up I ported the number to AIrtel..everything works like a charm on JV9 I must say now..can vouch it's a network issue at the location

I am getting constant 5 bars on the 2G network. 3G gives me 2 bars at max.
Asked Vodafone about the future of 3G in my location and they said "We are spreading, sir. We will keep you informed".

I've had this problem too when the phone was constantly switching between 2G and 3G/3.5G. Try adding "Toggle 2G/3G" to notification drawer, set the "Network modes" for it to 2G/3G Only or 2G/3G Only/3G+2G. Switching between modes can take 10-20 seconds, but you should be able to test if you can get good enough 3G only connectivity (in case it is just a network switching problem like for me).

If you want 3G only, Dial *#*#4636#*#* - Phone information - WCDMA only.

Wifi hotspot

I have a weird issue with the wifi hotspot on ZUK-Z1. I switch it on and it switches itself off again. Then gets in a loop. Off on, off on. Sometimes it will work for a few minutes.
I'm on EE UK 4g if that makes any difference
Anyone else have this issue? Or does anyone know if there is a fix?
Thanks

Men, i'm french, internet provider : Free (name)
And i have the same problem...

Yes, this is a bug in lineage-14.1-20170130-NIGHTLY-ham.
Hope that developers will fix it soon.

A workaround is to change to 3G just while the hotspot is on. That works for me. I don't use it too much anyway.

My first Z1 was stable as a rock but I have to say when I used mobile hotspot I was on 3G, that network did not provided 4G. Now I bought a second Z1 and I do see that this one is very unstable resulting that my laptop is "loosing" the hotspot and searching for another networks.
Will try this "trick"...I will see how it behaves in other locations to as it could be well that the old traditional building is somewhat blocking the signal.

There are no chances of it being a hardware issue. Because you told that it works fine when in 3G network. You can simply rule that out. And I don't think your network provider has something to do with turning on your hotspot! ???. It might be just a software bug. Are you on any custom ROM? If yes, then which?

Tried hotspot today in the same location but changed it into 3G instead of 4G...rock solid, no interruptions nor did my laptop disconnected once! I did read somewhere (was it here?) the the Z1 has less 4G freq bands explaining the unstable connection.

Problem Keeping LTE Signal

I am having a problem on my phone where I am frequently losing LTE - my phone goes to 4G and I have trouble with data.
If I turn Mobile Data off and back on it connects to LTE again.
This seems like it started happening after I updated to the GoldenEye ROM - before that I feel like my LTE coverage was a lot better and more consistent.
Can anyone advise me on how to diagnose and hopefully fix this issue?

3g/H/H+ switching problem

So I've searched for about an hour now for some way to disable the H/H+ options of a 3g connection, but no luck. Is it carrier specific? I know there are codes for it, but those are only for samsungs and etc. I have a Huawei Y625-U32 and the codes do nothing. The problem is that the game i play doesnt have constant data streaming back and forth, and thus fails to keep an proper H+ connection open, and as it is constantly switching back and froth this causes lag, which renders it semi unplayable. Is there any way of keeping the H+ connection alive constantly? is there a way of disabling the switching to H+? either of these would work, i think. I could always just stay at 2G because the game doesn't need high internet speed, but then you have ping issues. Any ideas?

Starting to get annoyed with the O variant phone in the UK

It's all too frequently dropping 4G or LTE connection when on the move. It's showing a connection, good strength too, but no data connection working. Often needing an airplane mode toggle or reboot to get online again.
5G is disabled as I'm nowhere near a 5G area.
Anyone got any ideas? Different firmware or something?
I'm starting to regret moving away from the SD note 10 plus I had. That phone was rock solid.

I read that some people have issues with connection with some ISP providers. Try putting it on 3G and see if it works fine then. If it does then ISP has either sn issue with 4G network or phone needs a firmware fix to solve 4G connection issue if this isn't a hardware problem thought. Since for me it works fine here and my 4G shows all time and I even have 4G+ as status without an issue.

try disabling WiFi calling that helped in my case

Tried all that. Went into a town and it didn't again.. Had to force it onto 4g to get a connection.

Haven't had any issues myself, on giffgaff. Tried O2 briefly, it seemed okay too.

Give this app a try, might help fixing it to one band

Yes u have that thanks. It seems to be band switching that's the problem. Or is it possible my carrier has live but unused bands that the phone is locking into? So when I travel I find myself with a dead data connection?
