Connectivity issues - Xiaomi Mi 9 SE Questions & Answers

Hello,
I have the global version of the mi9SE and experiencing very annoying issues when trying to access certain websites OVER MOBILE NETWORK (WIFI works) which returns errors as per attached screen shots, reporting certain sites (banking particulary) as can't be found or offline.
I temporarily managed to fix the issue by changing APN settings from IPV6 to IPV4 as per a suggestion on the forum of my French network carrier. Unfortunately with the update to android 10 and MIUI 11 erased these settings and now 4g or 3g for that matter simply fails to connect over IPV4 setting after update so I’m back to square one which is immensly irritating.
I can’t work out if this is a carrier issue or a software bug. I’ve tried the following :
- Changing Sim to another phone. No problems there.
- Changing browser. Both chrome and edge are the same as well as the native browser.
- Contacting bank who tell me issue not unheard of but have no solution.
- Contacting my carrier who claim not to have an answer.
I haven’t tried another sim in the handset.
Help would be much appreciated.

Hi
I also use French carrier, bouygues, using android 10 miuimix, just tried ing website and it works fine through 4g.
Have you tried a different ROM? You should have a menu to erase connectivity data in settings may be it could help

Hi thanks for your reply. Vey strange, I too am on Bouygues network and ING website doesn't work for me.
However I must point out that it is the secure part of the website that doesn't work so logging into the "espace client" part of the account, the home page DOES work. Same for you or not ?
I don't understand how it can only be me experiencing this issue which I've had for months now despite doing a factory reset, formatting etc. I'm using the stock global rom OTA from Xiaomi. I surely shoudln't have to flash another rom to get a working phone. I take it Miuimix is a ROM you're using on the Mi9SE ? Just how stable and secure is it ?
tks

MY WIFI hotspot won't work either. It connects to the network but refuses to connect to the internet. No such problem when placing the same sim into another phone and setting up the same hotspot. Could this be a problem with my device hardware I wonder ? I haven't done anything in particular...but these issues weren't there when I first bought the device.

For Hotspot I guess it's related to Android 10 update...
Just tried the secure part of the ing website and indeed it doesn't work for me neither on 4g. But Hotspot works fine.

Great thanks so much for trying at least I know it isn't just and so can conclude an issue with MIUI and the phone. Strange how adjusting VPN settings to IPV4 used to work but now doesn't. I fear the issue is embedded into the OS and I'll probably never find a solution . Wouldn't be so bothered if this was the only site but it's not. I first thought it was just a problem with the websites, then realized it wasn't when the same sites worked over WIFI.
As for the WIFI hotspot issue, still no solution to this problem. The same sim is fine in my Motorola and connects to the internet perfectly over 5ghz band. If I try 5ghz band on the SE, windows simply reports "unable to connect to the network" and over the 2.4ghz the device network will connect but reports "no internet".
It doesn't sound as If the two issues are related from what you say. Is it possible it's the windows firewall blocking the Xiaomi but not the motorola ?

[Q] won't connect to data network

Hi! i'm using XDANDROID 2.2.1 with the latest update. the unknown problem that I discovered is that it whon't connect to data network. The network operator said that i dont need settings for the data connection but if the phone insists then i should use APN = ppinternet. tried bouth but didn't work! what shoul i do?!
Can you provide more info? Like, what build you're actually using? (Saying you're using "the newest" doesn't mean anything).
Also, what network operator are you on? You can make/receive phone calls/text messages?
Have you ever been able to use data on Android? Does your provider require a proxy?
this ([prj][XDANDROID][2.2.1][AOSP][24.01.11]FRX04 MINOR UPDATE. IMPROVED 3D performance)
my network operator is Digi mobil prepayd Romania. yes! i can make and receive sms/calls. no, i wasnt able never to make a data connection with my carrier.(in WM works). No, my provider works without o proxy. in fact, it works without any settings @ all. Im WM the only thing i imput for my connection to work is the connection name. the rest i leave them empty.
Try going into settings->wireless & network settings->mobile network settings->access point names->then add new apn. Set the name to Android and apn to Internet.
tried! wont work!

SOLVED! It seemd that all was fine EXEPT the RECEPTION!!! It seems that XDANDROID is'nt so good in connecting me to the network in places where WM6.1 ENERGY is!!! hope the AOSP team will get this note!
Well AOSP= Android Open Source Project so just google made the aosp and maybe the settings are wrong, for me everything is fine, and still in romania. Using latest build.

SoD's definitely are related to poor service - it seems even worse when the phone is flipping between 3g and 1x or EDGE.
If this is a problem, run WinMo - as you said, it works fine in WinMo as our current RIL is atrocious. It's being worked on, but again - this is a work in progress, still under heavy development.

Hello, i am new inn the forum and new with WP/ terminals.
I have now a HTC HD7 surround, i am from Argentina, and my cellphone company is Claro Argentina.
My HTC is free from factory (at&t) , so any SIM is running well, but i have a navigation problem:
I can´t browse the web with 3G, i can via WIFI, but not 3G.
I have a iPhone 4 2, and i can browse the web with that phone and same SIM.
I already added differents APN´s and downloaded the Connection Setup via Marketplace.
I reseted the phone 3 times
The problem still here.
when i try to use the IE, in the navigation bar, i type some address, and after less than 1 second i see this :

Hello man, I have exactly the same problem with a LG E900 with Windows Phone 7, the phone was bought from Spain (Movistar), everything is fine except 3G.
Did you find the solution for this?
does 3g works at all or are you having problems only with IE?
go to the dignotic page
Intall the diagnotic app and look at post #150

Hi sandrobber, I have a LG Optimus 7 and the same problem, the wifi and EDGE and Wifi works without problem, I've checked and my mobile operator uses 850UMTS band for 3G and the phone works with that band, I've set the correct APN but I still without 3G and EDGE really sucks!
I've check the post #150 in http://forum.xda-developers.com/showthread.php?t=839154 but I can't find any place to use these codes in order to set up my 3G automatically, that codes works with my LG Phone? How can I enter those codes?
I will really appreciate your help.

I have the same problem too, and mostly on EDGE... I have to restart the phone to get it working again... Very frustrating if you tell me.
LOL, now that you all say that , I have the same problem to.
I need to turn off 3G if I want to have an internet conection.
did you all flash some rom's on the phone ?

The thing is, I don't have 3G 2100 in the country I live in
I can only rely on EDGE, so activating/deactivating 3G is useless for me.
I didn't flash. Just upgraded to 7392 two weeks ago.
I'm looking for a way to completely reset the network stack (equivalent to a reset) in order to re-establish a fresh connection.
My old Nokia E63 with the same SIM card had no problem establishing data. The only problem was the sometimes, the connection was really slow to attach (something like 15 seconds). I therefore suspect that WP7 phones have a too stringent timeout problem, i.e. the phone gives up trying to establish a connection after a failed first attempt (the phone didn't wait long enough).
I am thinking of just reflashing only the radio rom from a stock o2 rom (I have o2 Germany)

Yeah you can try that. I have the gut feeling that it's firmware-dependant. If someone can try with the latest Samsung FW that's been posted recently... I'm a bit lazy to lose all my settings

[Q] One M8 Tethering issue

I looked all over the net but did not found anything on this,
So the thing is when I enable the hotspot my devices connect to it with no problem but the phone itself looses connectivity meaning the internal browser or any other app for that meter cant get network connection....
It was true for the stock ROM, I also tried the Viper, same result.
Now running the latest GPE ROM and the issue is gone, I do like the original version and want to get back to it so I'd appreciate any feedback
anyone else has that issue?
thanks.
Really? No one encountered this issue?

I found a solution just in case some one will face the same problem
the problem was that there was a special APN for modem use, and the phone would use it by default when in hot spot mode
the APN comes with the stock roms by the way, so I just deleted it and now it uses the default APN while in HS mode that way both the phone and the connected devices get network connectivity
Glad it's not just mine, I tether my M8 to my car HU. The HU connects to the hot spot by there is no data pass through. I've tried opening a web page on the M8 to force a data exchange but still nothing. This is intermittent tout very annoying when it happens.
Where in the menu do you alter these APNs?

Question Mobile data interruptions on POCO F3 - is there any cure?

Hello, I tried searching on XDA and elsewhere but could not find an answer so I hoping to receive help by writing my issue here.
I have bought two POCO F3's 128GB & 256GB on Amazon & Aliexpress respectively.
They both have the same issue when using mobile data (4g) loading websites and doing voice & | video calls like FB messenger there are interruptions like for a second there is no sound or video freezes. It does not happen on wifi or other phones.
I tried resetting APN, selecting proffered network to LTE, rebooting, switching SIM slot, resetting wifi, mobile and bluetooth settings. Updated both phones to MIUI Global 12.5.1 still no luck.
Country Lithuania (EU) carrier TELE2
We really like the phones, but this is pretty annoying as we do a lot of video calls due to quarantine and what not.
Amazon suggested to replace the phone but seeing as two of them having the same issue it will most likely will not help.
Anyone experienced these issues and came up with solution?
From what u described, seems to me is a bandwidth/mobile data speed problem. Looks like is not enough bandwidth for video call to work properly. So, what is ur bandwidth provided by ISP? What mobile data plan had from ur telephony provider? Maybe ur mobile data signal is low in the place where u make the call from. It can be so many reasons for the issue u confront with, other than a problem with phone itself (a hardware/software issue).
you can also try the latest china stable firmware 12.5.4

Hi, ty for reply. That should not be an issue, reception is great and we tried it in multiple locations. Our previous devices Iphone 6s/ Poco F1 worked flawlesly with the same carier.
Here is speed test done on mobile data.
Any other ideas?
Found this thread here and I found a solution. Apparently there's an issue with network interruptions in general, especially on phone calls. This can be avoided by switching on VoLTE and WiFi-Calling. This is what I found out over time.
Here's the fun part though: Through a little bit of research this turned out to be a vodafone-problem. I am just guessing you guys will be either also on vodafone or on the corresponding bandwidth in your country.
It seems to be a bug in the F3, but also something that happens when VoLTE is not activated for your SIM card. The phone will try to use VoLTE and this connection will fail, forcing the connection to reset. It will be back in 10-20 seconds, but this is of course super annoying whenever a stable connection is needed (like phone calls...)
Enter *#*#86583#*#* (86583 = VOLTE on dialpad) on your phone. and it will give you a feedback that the carrier check has been disabled. Note that this doesn't mean that VoLTE has been disabled. Checking the network for the capability is disabled then, which makes the setting visible on the SIM card settings. Same works for VoWifi btw.
Try playing around with those settings and see if the connection drops persist. I have no logical explanation why this is happening because what I am telling you is obviously call-related - and I do realize that what you're describing is about the data connection. For me this was related however and solved my issue.
Possible solutions:
a) try to get your service provider to switch on VoLTE for you (this worked for me). You're going to need to call support for that. They will reset your SIM card in the process. Reboot your phone and be done with it.
b) If a) is not possible, deactivate VoLTE in the menu that you activated with the code above. If you're lucky, this will stop the phone from trying to get this type of connection working, even though it's not available. This is broken exception-handling on the phone's side and Xiaomi promised to fix it. They are aware of the bug (since Aug 20th btw) and promised to push a fix into the next MIUI release
c) play with the settings and try to get the phone to not use alternative protocols, just 3G and 4G, also deactivate Wifi-Calling.
Hope this information will help somebody. If all goes well, Xiaomi will fix it and this will behavior will be gone in the next release.
same issue for me with 12.5.7
data interruptions all the time and full signal loss
very disappointed with this device from the day i got it.
O thought I'm the only one facing this problem.
It's so annoying to get an interrupted connection in the middle of the game.
not only game, and calls, i have too much trouble to get throught a call.
Hello all,
i was also affected by a similar issue.
In my case the symptoms were:
On mobile data/5G some apps would be accessing the internet but others wont..
I was able to overcome this by resetting the access point settings and then applying the ones found here:
Cytamobile-Vodafone Cyprus APN Settings for Xiaomi Poco F3 GT - APN Settings
apn.how
I hope it helps...
My fix for this occasional issue is to set the phone to '3g' only in network settings, then flick it back to '5g'. It seems to be area specific for me. Very bizarre.

I have the same problem, it helps to have the settings volte and vowifi enabled. Sometimes it looks low cell signal and loosing the connection.
Has anyone return for service the device?
It looks like we still have this problem, my F3 modem is crashing every few hours especially when it switches bands, very annoying.

Hey I ran into the same problem in Hungary Vodafone Poco F3, 14.07 MIUI
4g net is working flawlessly but
Network connection is lost when start dialing
Nobody can reach me on phone
Enter *#*#86583#*#* (86583 = VOLTE on dialpad)
VoLTE select option turn on/off
Enter *#*#869434#*#*
VoWiFi select option turn on/off
I tried to switch on/off both but no solution just yet
sby has answer for this?
Where should I post this problem to be solved?
I also have this problem and I am from Iran. My mobile ROM is the global version. It seems that this problem is caused by the Poco F3 mobile hardware itself. If anyone finds a solution, please let me know, thanks.

Question 5Ghz Hotspot Problems

Hey,
Wondering if anyone else is having problems with 5ghz Hotspot wifi tethering? I can activate the setting but I can't always connect to it with my other devices. Most of the time it works the first time I activate 5Ghz hotspot, however if I toggle it off and then back on again, it won't work anymore until I restart the phone. The UI will show me that the hotspot is active but my other devices won't be able to find it.
I've tried it on multiple roms including a fresh install of the latest default MiUI rom, all with the same problem. I saw posts on reddit claiming that it could be a UK region bug and to try change the region to France but this doesn't solve the issue either.
2.4Ghz hotspot works everytime, however is a bit slower than 5Ghz, so I'm keen to try and get this issue resolved.
Any help is appreciated.

Yeah I understand that, however that doesn't explain why the hotspot works the first time, and never again until a device reboot.
My other devices support both 5Ghz and WPA3.
