When I am using a mobile network (both 3G and 4G) and the signal is low, sometimes I lost connection (That's normal), but the stange thing is that phone don't reconnect soon and it remains offline. I have to manually reboot or enable/disable airplane mode... and the signal come back.
I'm using Mi 9 for about 5 months. I am on the last firmware and even on old versions same thing...
Anyone has got similar problems?
Hi i have also some problem with my connections, I am from Germany I got my Mi 9 since a week (Rom was Global Europe 10.2.30 EEU) now I have the Global Rom (10.2.13) but this is also no solution.
Sometimes it shows me a Network but I tried to call my girlfriend and it has no dailtone, also it shows me network but I can't receive calls, same problem I have with mobile data, it shows connection but then it isn't connect to the internet.
if I switch off the mobile data connection and switch it on then I have normal connection.
I hope there will be a fix in the next update....I heard that some people have that problem.
Mine loses signal sometimes on the subway but reconnects by itself in 30-60 secs, i find that a bit slow but overall I think it holds onto the signal better than the phones i had in the past. This is the type of issue that would be solved in 1 month at most but here we are, an update almost every 2 months that "optimizes" one thing and weighs in at 500+ MB.
Mine have the same problem. When I'm on the subway it lost the signal and when I go out to the street again I have to enable/disable airplane mode to get signal again, because it can't connect automatically like a normal phone.. I'm from Mexico and I have Global ROM 10.2.13.0

I have a similar problem. Where I work the phone goes from 4g to 3g, to avoid this I open the phone settings 1 (by entering * # * # 4636 # * # * on the call keypad) and switch from lte / td-scdma / umts which is default option to only lte.
The problem remains the same when the phone loses the line and then finds signal again, because although there is signal after I do not receive photos or audio from wa or cannot I access the services of play store for example and I have to switch to default option again...
I'd like to know if there was a method to increase the power of the antenna module even just a little with root permissions ...
I have a similar issue, especially when I am driving car - I am from Germany.
When I start driving with Google Maps open (to have an overview of the traffic), after about 30 minutes my Mi 9 loses connection and won't reconnect, even if I switch on/off airplane-mode etc. This does not happen every time, but relatively often. To get back network connection I have to restart the phone.
About 2 days ago when I was home I lost connection again. Google Maps was still running. After closing the app my Mi 9 immediatly connected to network. That may have been coincidence, but next time I will close Google Maps if my phone loses connection again in the car and will report here.
I am on Xiaomi.EU 9.9.26 Android Q (I just installed *.27 v2), had the same issue on different Xiaomi.EU Android P releases.

It happened to me several times and I can't understand why ...
In this case the connection seemed to be good too, I had all the signal notches in Lte, but in reality it was absent.
I had to restart.
Known problem it seems...?
Hopefully Xiaomi will fix it soon.. wonder if custom ROMS have the same problem

So, as I said I report back.
Today again after about 30 minutes my Mi 9 lost connection (0 bars). Again at about the same region. Probably the connection is bad there. However, my Mi 9 didn't reconnect even after few minutes (sometimes I waited 5+ minutes and IT didn't help).
I closed Google Maps and another App, which requires GPS. Nothing happened. Then I deactivated GPS from the quick menu and my Mi 9 connected immediately to the network with full bars.
I have "o2" as network provider.
Xiaomi.EU 9.9.27 v2 ROM.

I changed to LTE only, and use it for some hours...
It didn't help. Same as before.
Thanks anyway

Yeah, I know, For me is the same.
When I lose connection I've to change to LTE, When it happen again, I've to do it again so I come back to default option.
I do this to avoid restarting the phone and to be faster, but the issue remain anyway...
But remember, When u're in "only LTE" option, you will not able to call
Workaround is change to 3G connection preference
Hi everyone!
I have the same issue and after lot of things that I have done, as change MIUI to Global version, now I can use 3G without problem, but if I try to use LTE/4G after some minutes using GPS in high accuracy, LET connection turns OFF.
So, my workaround is change to 3G connection preference when I need to use Waze, Maps or any other app high accuracy.
I have the same problem too, and I always have to reboot the phone to get the data/wifi to work again. But just a minute ago I had the same problem and I just killed all tasks in recents and the network came back without having to reboot. May be coincidence or I'm on to something.
From experience this problem should have disappeared for quite some time now.
I have always been using EEA ROMs. I believe I have not seen this problem at all in MIUI 12. It has been such a long time since I last saw the problem I don't really remember if this was fixed during the MIUI 11 era.

Which ROM/Firmware are you using?
Try disable and enable airplane mode instead of rebooting

Exactly.
Since the Redmi 8 don't have 5ghz Wifi capability we are stuck with 2.4ghz wifi and on my 2 Redmi 8 devices with Bluetooth enabled that kills the speeds to about 5mb. Apperently Bluetooth and 2.4ghz wifi run off same hardware or software and don't appear to play nice together..
I use multiple different wifi connections a day and was a problem for me. Anyway so this was the workaround that fixed the problem for me and my device. Pretty simple and straight forward and suppose it could work on other devices with same issue..
Always only try this at your own risk.. *As Root is Required*
First off: I'm located in Canada, could be different in another region.
I have a unlocked bootloader
latest stable Xiaomi.eu rom for the Redmi 8 installed
Official TWRP installed..
2: *Root Required*
Download and Install latest version of Magisk and flash via TWRP
3: Download and install Service Disabler from Playstore and Grant su permission after opening the app .
4: Search for Google Play Services and click on that .
5: Scroll down the list till you find NearbyMessagesService and click it to disable it permanently.
6: Now Make sure you have Google's "Nearby" functionality disabled
Go-to your Google account - Device connections - Devices - Show Notifications off.
Now back to settings - Passwords and security - Location - Scanning - turn all off
And reboot.
Now my other device is on stock MIUI and I haven't tried this on stock rom as of yet. It's my wife's device so if she lets me I will test this on her device as same issue is present.
In time I will try to see if this "fix" will retain if I unroot the device after..
*Update* this will continue to work if you unroot device.
*Update* when I installed latest Xiaomi.eu rom 11.0.10 sometimes it don't work till I reboot. Not sure why yet.
thanks for sharing
but for me I just changed the Channel used in my router and everything works fine

try channel nom 10 or 11
guys you have slow wifi because your wifi and bluetooth are using 2,4ghz they interfere with eachother you need to download an app like wifi analyzer and go to the last tab then look which channel isnt used and use the channel which isnt used i hope i helped you
without root is there any fix?
Yes WiFi and Bluetooth in same frequency range but that should not cause problem. My mi 8 lite manages to communicate with my mi band 3 and use WiFi ok. I had an ulefone and that worked ok. I had a blackview and that worked ok. The redmi note 8 pro did not. At first I thought it was maybe a bad chip that was leaking so tried another with same result. So its hardware related or software. But it's not the fact of both using same frequency band. As Bluetooth is not as strong a signal I would have expected that to drop not WiFi.
Xiaomi should have sorted this by now. Miui 12 still hasn't fixed this.
Fix for home wlan use

This is a big problem and Xiaomi should fix in the next update!
However if you mainly use Wifi at home, change the wifi frequency to 5ghz and the problem is gone.
In my modem/router you can do separate 2,4ghz and 5ghz networks (both work at same time), so my Laptop and Xiaomi phones are on 5ghz (a lot better speed in both) and old hardware are in the 2,4ghz network.
Didn't know this before, but now also my laptop wifi speed came from 30-40mb-> 120mb.

Redmi 8 doesn't support 5ghz network as stated in first post ...

Are you kidding me? Well, what a waste of mobile I have bought ... everything is fine except for something as important as connectivity. Ok Xiaomi ... Does anyone know of any ROM that this failure does not pass? so far all the ones I've tried happen the same ... :crying::crying:
I also tried the proposed fix (on latest Stock rom / Android 10) and unfortunately it did not work Any other suggestions how to solve this extremely annoying bug?

Install a custom rom like HavocOs
I have the solution ===>>> youtu . be / WMksEEKXlJY
The problem is interference with Wi-Fi and Bluetooth Scanning.
DISABLES THESE TWO CONFIGURATIONS
On MIUI 11:
SETTINGS >> Passwords & Security >> Location >>> Scanning >>>
Wi-Fi scanning> (OFF)
Bluetooth scanning> (OFF)
On MIUI 12
SETTINGS >>> LOCATION >>> Scanning >>>
Wi-Fi scanning> (OFF)
Bluetooth scanning> (OFF)
This will solve the problem of drops in the wifi.
It is NOT POSSIBLE to use Bluetooth in conjunction with wifi. But with these settings disabled, you can use wifi with better quality (as long as Bluetooth is disabled).

Thanks. I watched the video, but unfortunately it is not in English, so I didn't really understand what the actual solution is. For me it seems, that your main "trick" is to switch from 2.4GHz to 5GHz WIFI, is this right?
Would it be possible for you to write a short manual on your steps here in English, that would be great!
Thanks, Lars

Thanks for the update.
Have already disables these options, but was hoping to be able to use Bluetooth in conjunction with WIFI, since my smartwatch is always connected to the phone by Bluetooth
So unfortunately no final solution for me :crying:

Thanks for the suggestion, moving from channel 6 to 13 did the trick! I can finally watch videos with Bluetooth speakers.
Would Xiaomi.EU fix these issues? If so, I'll aim for that ROM!
Hello everyone, i hope someone can help me with my problem, i have a Xiomi Mi 8 global version 6 ram / 128 rom With the MIUI Global 11.0.4 | ESTABLE 11.0.4.0 ( QEAMIXM ) so the problem is when I'm using the Bluetooth with any device and the WiFi is turned on at the same time, the WiFi signal is very slow and it gets disconnected all the time and if you try to use the mobile data it happens as well but curiously the Bluetooth signal never gets disconnected. What should i do? Someone can help me?
tried on all the android 10 and 11 roms I can find right now, can't get any gps signal without wifi services. Are there any fixes for this? I tried to reflash my modem but nothing changed so far.
My redmi note 9 is on miui v12.0.6.0 QJOINXM (Indian version). The wifi router in my house supports 2.4GHz/5GHz dual band. My phone often disconnects from wifi. It is like the phone is showing connected to wifi but there is no upload or download speed. I have to turn off the wifi option in phone settings and turn it back on for the connection to work again. It happens every 1 minute or so and it is very frustrating. Please if anyone could give any suggestions.
I am also facing the same problem. Did you get any solution?
Same here, bloody annoying.
Connects to access point no problem, remains connected to access point no problem but it's pot luck if you get data flow.
Using my Redmi right now, so hopefully this posts ok.
