Installed LineageOS, latest nightly, on my Redmi Note 3 SE (kate). Unlocked bootloader. Flashed psy_man's latest firmware for the device at the same time.
Since switching to Lineage, I get very slow LTE download speeds - around 0.5Mbps. Upload speed is fine (maxes out around 5Mbps). On my iPhone 6S, sitting right next to the Note 3, I am getting normal speeds, connected to the same cell tower (16Mbps). Checked APN settings on the phone - everything is correct.
This did not occur when I was on MIUI, so I'm guessing switching to Lineage is the cause. Any ideas?

I rebooted a few times and the problem seems to have sorted itself out.

Hello,
So I've been using my Xiaomi Redmi Note 3 Pro Global Edition (kate) for a month now.
Everything's been going great except for one bug that's really annoying : when I enter an rural area with only EDGE, and then get back into an area that has 3G, H+ or LTE, the phone doesn't switch back to a better data network.
I've found a trick that allows me to get a better network back, by changing the preferred network type to 2G and then to LTE again. Only then does it finally detect the LTE network. It works but it's annoying to have to do this everytime I want to search for something quickly.
I'm currently using CyanogenMod 13 for kenzo with kate modem flashed, but I don't think this is the source of the problem as I previously used MIUI 8 and there was the same problem.
I live in France but I'm almost sure the bands are not a problem as I can receive LTE, but it just doesn't switch to it when on EDGE.
I'm hoping you have some solutions.
I (living in Switzerland) have my Redmi Note 4X ("International", includes Band 20) since approx 2 weeks now. Unfortunately I am having "problems" when on LTE (cellular data). Before switching to the RN4X I had a Mi4c (and before that a Samsung GSIII), so I am comparing to these.
When out of a wifi I "often" have no internet connection. I installed "LTE discovery" app which allways shows signal reception in the bands 3, 7 and 20 (I guess I have seen band 1, too). The bars toggle (even when not moving) from 1 to 4, though. I seldom see a switch into the 3G net.
I am currently running
cm-14.1-mido-firmware (could the modem-FW "in there" be the problem?)
RR 5.8.3
Unfortunately I can't say whether the "problem" described existed from the very beginning (i.e. with the original MIUI) because I switched to RR on the very first day I received my RN4X.
Is this a modem-FW or (even worse) a HW issue? Can/should I
1) download the latest greatest fastboot ROM from here
http://en.miui.com/a-234.html
2) extract the NON-HLOS.bin (which is >80MB, whereas the bin you linked is just 36MB)
and
3) flash it (as explained by T.Ru)
What else can/should I try?
Thx for any advice
Clemens
PS: Excuse the flaky wordings: "problems", "often", "sometimes" etc. but I can't be any preciser
Flash this firmware zip from twrp. I hope it will be fixed

Hi, did you manage to solve your problem? I'm having some too (even if data works fine, I have problems with the voice network, when it comes to receive or make calls or messages).
As of now my "workaround" is setting "Preferred network type" to 3G /
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.
Edit:
Best explanation: https://forum.xda-developers.com/showpost.php?p=76811230&postcount=157
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?

With the data on? I don't have issues when data is off but when on internet, every few minutes, sometimes every few seconds i lose network and data transfer for a 10-15sec
LOS last weekly 24/08 and i have this problem. Is there a fix for it?
Bump - Any fix? What firmware?

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.
I have updated just now to MIUI 10.1.2.0 Stable but still am not able to detect 5GHz on Wifi. This is really annoying. I have tried resetting network settings, replacing SIM and finally also factory reset. Nothing seems to work. Please suggest a way out guys....
The weird issue I have is, when I reboot the phone it recognizes the 5GH network and connects to it with no issues. However, when I go out of range of the 5GHz network AND come back, the phone does not recognize any 5GHz networks. I reported the bug on the official Mi website 2 months ago and I have not heard anything from them. I'm on MIUI 10.0.4.0.

That's much weirder! Did you not try to visit there service centre?
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..

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.
