Hi
A few days ago I started experiencing a strange issue that I just can't resolve.
Certain apps and accounts, i.e. Facebook, email, playstore, Google, Flip board etc. simply will not load/refresh/sync over mobile network. However, I can still browse the Internet using various apps (chrome, stock browser). With Spotify, I can stream music but am unable to download. There is no issue with the data connection as I am getting 'H' or '3g' and showing decent stats on Speed test. I have no issues at all over Wifi - everything works perfectly.
It's as if something is preventing apps from syncing/refreshing over the network but not affecting Internet access.
I have an unbranded device with a sim only Talk Talk deal.
Kitkat 4.2.2
4.12.401.11
I'm going to do a hard reset next but wondered if there was another solution.
Any ideas?

At work we had a phone that did not want to sync email on 3G. (Perhals other apps, we did not check.)
It turned out his phone was roaming on 3G, and the email client was set not to push mail when roaming.
I think the guy had bad signal on its own network on this location and so the phone was roaming.
He could still use his browser and many other apps without any problems.
Maybe it has nothing to do with your problem but I thought I should post it.
Because it sure has many things in common, also in this example on WIFI everything would work fine.
Kind regards, Stefan.
Thanks for that, unfortunately it doesn't seem to be a roaming issue.
I've just factory reset the device, completely wiped everything. Tries to log into Facebook and the same thing happened. Switches to WiFi and it worked straight away.
I tried forcing the mobile data to only use WCDMA. This actually seemed to resolve the problem temporarily and I was able to update Facebook however it soon reverted to how it was and I was unable to sync email, update Facebook or download on Spotify unless over WiFi.
I'm wondering if it's the Sim card or possibly a problem with the phone but I'm struggling to understand (albeit with limited knowledge) how this strange behaviour could be hardware related...
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.
I just bought this phone and I'm trying to use it in my network. I use Ubiquiti products (16-port switches and a bunch of AP access points). I connected the phone via wifi to my network and it has no problem for a while until it just doesn't have Internet connection. It stays connected with its IP address intact but for some reason it cannot seem to reach the Internet. The workaround is to simply turn off the wifi module and turn it back on. It's randomly happening and the workaround is very annoying.
I have a couple of other mobile devices (iPads, iPhones, Android phones, Windows laptops, etc.) and I never experienced the issue with these. I tried connecting the Redmi 9C to all my wifi networks:
Guest wifi with captive portal
Main wifi with RADIUS authentication
IoT wifi with regular WPA2 personal authentication
I tried resetting the wifi settings of the phone. I tried reinstalling the latest MIUI fw/sw.
and the result is the same, every time. At this point, I can safely consider that there has to be something wrong with the phone. I'm not sure if it's because of the MIUI 12 update because I updated the phone to the latest firmware as soon as I got it out of the box. Is this a known issue with this phone? I have another Xiaomi phone (Mi Mix 3) on the same network without any issues.
Any ideas?
Same thing is happening with my Redmi 9c
I am encountering the same problem with my device.
I have my region in Bangladesh (the country I live in) ,tried changing it a few times. Also upgraded my MI UI version but nothing changed.

I don't face this problem in my device which framware you using
Try to update in leatest framware
I always use the updated firrmware but it's too late, I returned and asked for a refund for this phone and replaced it with a Huawei Y6P.
I'm having a similar issue with my redmi 9, wifi works fine but all of a sudden it stops working even though it's connected. Apps dont load, messages dont go through and i have to toggle the off and on wifi. I'm on miui 11, there are no updates available when i try to update but i'm about to ask for a refund. This issue is very annoying
Hi, today I received the EU update to MIUI 12.5 - 12.5.1.0(RFAEUXM) . However, now my Mi 9 can't connect to wireless networks. I already tried restore the network defaults and then the factory reset without success. Any ideas?
The behavior is - I move the switch to turn on, seems like it is on but no networks are displayed. If I move away to other apps and then look again for wifi switch, it is off again. I feel some lag when I go into wifi settings pages and after turn the switch on.
Do you have some system apps disabled? I remember similar behaviour when I used to disable/remove system apps on Q.
If factory resetting did not help you, then it's definitely the OS has a problem. Wait for another update, or try to reflash the latest firmware using PC.
No, I don't :/
I already looked into logcat and seems related with the wifi driver the issue:
07-12 16:42:33.989 846 846 E [email protected]: Failed to write driver state control param: Invalid argument
07-12 16:42:33.989 846 846 E [email protected]: Failed to load WiFi driver
07-12 16:42:33.989 846 846 E [email protected]: Failed to initialize firmware mode controller
07-12 16:42:33.989 846 846 E [email protected]: Wifi HAL start failed
It's complicated just live with mobile data and a limited plan until a new update. I believe that I can't reflash because I don't have the Mi 9 unlocked and to unlock it I should wait (360h I believe). I already tried the "download latest package" from "about phone" but I still have the wifi issue.
Downgrade or flash another ROM should work but as I said I have the phone locked.
That's a lot like Kernel issue, small update should fix it. Send a report to Xiaomi regards the issue.
Since you're locked, you better wait this fortnight.
Same issue here, have tried to reset Wifi, Mobile network and Bluetooth settings but no improvements
Have restored MIUI 12.0.5.0 from Fastboot in order to get Wifi working again...
Very bad work from Xiaomi for this

I first experienced this issue after updating my mi 10t global to 12.1.3. It's a known bug and has been discussed at greater length on the mi community website. It remains unfixed in the 12.5.1 update.
However, there is a temporary solution that will allow you to reconnect to your wifi network. You'd have to change your ip settings from dhcp to static, and enter the relevant digits. That's it.
On a separate a note, 12.1.3 also introduced a mobile data bug that remains unfixed in 12.5.1. If you've set a private dns provider hostname under private ip, you will no longer be able to use mobile data. You'd have to toggle this setting to off or auto to get mobile data working again.

If you're able to see your wifi network name listed under wifi assistant or available networks, even if it's not active/connected you should be able to press the arrow on the right and enter the settings for that network. Here you'd have to change ip address from dhcp to static, then enter the relevant digits in the spaces that appear below (assuming you know what they are). Then press the tick up at the top right to save before exiting.
I have same problem
I found this on Youtube and its work for me
This is definitely not the same problem.
Our issue is about the Wifi that is not working at all, no wireless networks, no connection, phone constantly crashing when entering Wifi menu.
Also, there is an issue with GPS Localisation (maybe related to the wifi as the phone is using wifi to have more accurate result).
Have received again today the 12.5.1.0 update and the issue is still here...

Same here, but the static IP roundabout don't works
My Xiaomi T10 could not connect only to *some* wifi, it has been so since when I purchased it.
I tried different solution and never worked.
Only few days ago I updated to MIUI 12.5 and I tried the first method here (basically reset the wifi settings)
Xiaomi: How to Fix Wi-Fi Problem When Updating to MIUI 12 | ITIGIC
Many of Xiaomi's phones are still updating to MIUI 12. The company's new layer integrates a large number of novelties at the aesthetic and functional level. However, as often happens on many occasions, there are problems that only arise when these new versions reach thousands and thousands of...
itigic.com
and it worked!
give it a try, hope this helps, it bothered me for such a long time!
The latest MIUI update automatically fixed all my wi-fi/data woes. It's about time.
Hello,
Got a Mi11 and ran into wifi problems, fought a bit...
My problem was that wifi kept disconnecting, just like in the video above (from nepal). I had noticed that it did not with all access points (specifically with mine !).
Having had the same problem a while back with an oculus go, I did the same : forcing a static ip.
Didn't work with the Mi but I [desperately] set the dns to "plain google" (8.8.8.8 / 8.8.4.4) and wifi sticked !
Then I checked my ap settings and noticed that my ap advertised its global dns (eg 192.169.0.254) and not itself as the dns provider, corrected that on the phone, that is putting the router adress as dns 1, and it works reliably now.
Looks like if android doesn't get a specific ip or address positively upon connecting an access point, it drops it to connect to the next, wich sounds like a good idea...
Hope that helps some of you...
Hello,
Thanks for your advice but this solution cannot be applied here as the Wifi cannot start at all and when you try to look at it after trying to activate it, system panel hang and crash.
I have tried to dig a little bit to see where this problem can come from but haven't found anything yet.
I have check the /persist partition as there is no way to check the Wifi MAC Address with MIUI 12.5.1.0 but no, the partition is still fine (as everything is working properly with MIUI 12.0.5.0)
I have opened 3 tickets by using the Xiaomi official reporting tool but nothing yet... I guess they have abandonned the Mi 9 as MIUI 12.5.1.0 is considered the latest MIUI for this phone.
It would be good to find some Mi 9 users that have successfully installed MIUI 12.5.1.0 (the EEA version) on their phone.
Anyone have tried the recent 12.5.2.0(RFAEUXM) on their Mi9?
In order to know if the wifi bug is still there or not.
Thanks!
I have the Xiaomi M11 lite 5G NE with Miui 12.5, when I exit the house, my WiFi turns off automically, so when I get back I have to toggle WiFi to turn it on again. I have seen some Adroid Advanced settings and one of them is Turn Off Wifi automatically. This seems to be activated, but I can't undo that setting.
Anyone else have this problem where your WiFi is turned off automatically?
Latest available MIUI 12.5 (12.5.2.0) fix the Wifi issue.
K20 pro, MIUI 12.5.5, stock china ROM not rooted
I am getting random mobile network dissconnects on both sim cards sometimes few times a day and sometimes only once a week or so. It happens only while navigating.
If I kill the navigation app (Waze or Google Maps), the network comes back in few minutes.
If I leave it on - I am stuck on "Searching for Network" and cannot even search for newtorks manualy...
If I reboot the phone - all comes back fine and I am able to continue navigation - no problems.
Searching the net found somewhat similiar issue with OnePlus - users there complaining they are geting network/s disconnect immidiatly when using any GPS app with Work Profile enabled.
So far I did:
Swap slots
Got new SIM cards (from the same provider)
Reset APN settings
Removed dual apps (they are creating Work Profile)
Delete/Re-install Waze
Tried ON/OFF Google Location Accuracy and Emergeny Location Service
Nothing seemes to help.
I am realy not very keen on Network Reset or Phone Reset at this point...
Any ideas please?
Updates:
Network Reset - didn't help
Flashing Official Global ROM 12.5.2 - didn't help
I am now thinking it is maybe a hardware problem... but it is still strange that immediately after restart, it will work fine for at least few hours (even few days sometimes).
Also still cannot figure how GPS receiver can cause network disconnect (Google also knows almost nothing of such cases).
