I can't connect my H850 to wifi band 13 after a random amount of time in a no mobile signal area. Seems immediate after a reboot, or drops band 13 wifi after a random amount of time with no reboot, SIM card remains in phone. When the problem is happening I get the message about wifi issue when toggling wifi off then on "Cannot search for all wifi networks. Check SIM card or mobile network". All other wifi bands are fine.
Phone purchased in the UK, but it's been back twice for repair, and each time comes back with new issue. I'm not sure if this happens on EU stock LG G5 that haven't had lots of part replaced. I think it's something to do with LG phones assuming they're in the US (where channel 13 is banned) unless a connected SIM tells them otherwise. Seems a big problem with LG phones if you need to connect to EU wifi in no signal areas. There's no option to set wifi regulatory domain in advanced wifi settings.
Is there any way of fixing this without rooting?

Unfortunately i had found the post after a long time. You will most probably won't have this phone anymore... I have the same LG and it just lately started the same problem to me too, so i would be glad if anyone had answer
Had this problem also. I've switched off channel 13 in router.
Every custom ROM for Redmi Note 4 SD has a bug that is making LTE signal disappear, you can verify it by opening signal info in settings.
You can see that the dBm signal stay at normal value but "asu" value is constantly spiking to "99" which causes signal indicator to show no signal for brief moment.
This happens for every ROM that is not based on MIUI.
Does anyone know what is the cause of it? We have sources released, is this a kernel issue or something else? It cannot be modem firmware since we are using same as MIUI. Can this be diagnosed/fixed ?
I remember it was the same few months ago, and still nothing has changed. I think it's the biggest issue and im wondering if anyone is trying to work on it.

I will mark this as resolved.

I think latest LOS has this fix approximately a few weeks ago? Have you tested?

I tested lineage-14.1-20170810-nightly-mido-signed few days ago, bug is still here.
Does it actually lose signal or is it just a visual problem?
Might be a carrier problem, currently staying at a flat 49-50 in Singapore on Singtel.

Watch the signal for 5-10 minutes, it will drop.
yeah.. completely agree with op.
Is this fixed or still there?

You need to enable LTE and Data.

I don't understand your reply.
LTE and data are of course always enabled on my phone.
The only moments where I lost LTE signal is when I drive and arrive at a place where there is no LTE signal.

Yeah. It can be solves, if it's showing wrong signal level
This doesn't look like a cosmetic defect. I was on MIUI Nougat and didn't face any issues with signals. After coming to RR Nougat, I can see frequent fluctuations in network. Lesser speeds, much less consistent connectivity. I have tried changing the sim, compared with a phone running MIUI on the same sim, there is an undeniable fluctuation, with intermittent loss of data. This seems to happen only when data is enabled.

Yes, worth mentioning is that the issue is with LTE (4G) with Data enabled, i didn't noticed any signal issues or disconnections using 3G with Data enabled. Someone smarter should look into this.
When I was on MIUI 9 there was no problem regarding network. After switching to custom rom(now I'm on RR) one thing is happening, that my network is fluctuating between different bands, resulting call drops. When I was using Jio 4G, I used network signal guru to lock the preferred band. But now I've switched to Airtel and network signal guru is not working anymore. The network is changing bands all the time. I've tried changing lots of ROM's, changing the sim slot, reinstalling the app, etc. But nothing worked. I'm on the latest global firmware. Can anyone help me out. Thanks in advance and sorry for my bad technical terms?.
Hi there,
This issue is a weird one, but I also had it on my old OnePlus One.
So I travelled to London on Tuesday, and I noticed on the train ride that my signal kept dropping out, thats fairly common, as its fast moving and passes through signal black spots. The weird thing is, when I'd regain signal, it would show a full signal bar, and 4g logo, but had a cross next to it and said no internet access. If I rebooted my phone, it would then regain internet access again. I got the same issue just walking around London. Full signal bars, but no internet, and a reboot would bring back internet access. Airplane mode toggling didnt fix it. Im from the Midlands, so my theory is that maybe when my phone gets passed over from one signal mast to another, it causes an IP issue or something? I used to get the same issue when travelling up north too on my old phone.
Could this be an issue with Lineage or Lineage based OS's ? My OnePlus One did the same thing and that was running Lineage OS 14. On my Poco F1, im running crDroid which is Lineage OS based.
My only other theory is that maybe there is an issue with my SIM card? Im using the same SIM card which was in my One, in my Poco now.
The only common threads between the two phones is that they both have Lineage based OS's, and they are both using the same SIM card.
Does anyone have any suggestions?
Thanks!

You can confirm if it is related to LOS by flashing the stock ROM and checking.

have you tried setting radio to LTE/UMTS auto (PRL) ?
you have to do this every single time you boot your device.. set it for both radios, then disable radio and re-enable them / toggle flight mode on and then off..

Unfortunatly, im not planning on doing any travelling now for a while, so I cant really test it.

I'll give that a go and see if it works. I didnt realise there were so many network modes to choose from. I have a lot of modes in preferred network type settings too, ive got it set to 'GSM/WCDMA/LTE' at the moment.
I do have a private DNS set too(cloudflare 1.1.1.1), could that be causing the issue maybe?
I'll see if there are additional settings I should have on according to my network provider.
EDIT: Just checked, and my APN settings were on the wrong network, could explain the issues.
set it to an option with PRL, do not use the in-device settings page, as it is not suitable for global use (rather china oriented). use the hidden menu as suggested above.
also it's always good to replace an old sim.
APN is very likely a cause as well, especially when roaming.
I have noticed this the signal does appear to have issues.
I had same problem when I had mi a2 lite I found the signal not so great but this phone you would expect to be better then that one.
I use two sims both on different networks which also use different bands well on sim1 others phones max signal on 2g/3g/4g but on this one it doesnt want to drop below 4g and the 4g signal is all over the place at times its two bars.
now on to the other sim this network around my home has always had poor 4g so with other phones it would drop to 2g/3g which i would then get 4 signal bars not on this phone again tries to stay on 4g with no siginal and if you select option to choose different preferred network the signal on 2g/3g is 1-2 bars only.
i tried let/umts pri on one of the sims made no difference.
I have tried this outside my home as well same thing it's only when i am really close to a mast will i get max bars for both.
Hi mates,
My mobile POCO F1 not showing any signal strength, I tried doing factory reset but no go same issue. Could some one please help me.

i have the same problem . can somebody help?
Hello everyone, I hope to find some help here regarding the bluetooth connection on the console of my car. Since the Oos 11 version, the network reception indicator on the console remains fixed. I no longer have the reality of network reception, whereas on Oos 10 it worked very well. Would there be a manipulation to do to rectify this concern. Thank you
