Mi 9 tethering problem - Xiaomi Mi 9 Questions & Answers

Hi I just brought a xaomi mi 9 in Beijing it's running the Chinese stable rom, I've just got home to Australia and I'm having problems tethering it to my windows PC but it tethers fine to my Android car stereo which is strange, I've never had this problem before. Anyone got any ideas of what's going on. I'm guessing the problem might be fixed when I change roms but I can't do that for another 15 days yet.

FIXED!!! I recently did FACTORY RESET 2 times, in the first time it didn't work, but after second time it works, at least until now hahah.

[Q] Bluetooth connectivity and BMW hands free no longer works with 4.3 update

Hello. I've only joined today as a result of the Samsung 9305 Jellybean Update 4.3.
I am on an EE T-Mobile UK i9305 LTE handset in factory condition, no rooting or any other modifications. I have just upgraded to the new update on 20 Jan 2014.
Apart from all the usual observations such as WI FI and battery life, I have another issue which I cannot find anywhere else.
Before the update and for the last year my i9305 worked fine with the bluetooth in my car. I have a 2004 X3 E83 BMW and the car paired absolutely fine. I would talk and connect with no problems. Since the update the phone connects to the bluetooth then drops after 3 seconds.
I have done the following:
Unpaired the phone and repaired;
Deleted the cache for bluetooth
Deleted the cache from the engineers mode
Samsung tells me that I now need to go to the dealer to ask them to upgrade my bluetooth software in the BMW, I explained that 1st I'm not sure if that could be done and second that would cost me money and time for something that was working perfectly fine 3 days ago for over a year. The only change is the update. Therefore I explained that there should be another update to correct this and all other problems immediately.
Has anyone encountered this issue with a car's bluetooth and anyone been able to figure out a fix. I don't really want to go down the avenue of trying a factory reset and testing if that works.
Many thanks
Havent had any issues like that with stock 4.3 and bluetooth so may or may not help but try clear the data for bluetooth share in application manager as well as un pair and re pair the device again after that has been done

Wifi and bluetooth disabled and telephone locking

Hello friends, good afternoon, how are you? I'm new here and I've already got a problem with my Mi Mix.
It is as follows, I bought it in aliexpress and it came with a shop rom in the first 5 days, great running 100%, however from the 6 started the problems, first was the bluetooth that turned off and did not call anymore, then it was the wifi that Was the same way and now the phone beyond these problems hangs and I can not use anymore, being forced to turn it off and on again, detail being that when it restarts it locks up after a maximum of 5 minutes.
I tried to pass the original global rom of a developer rom and lastly MIUI BRASIL, but I did not succeed and the problems continue.
I entered the wifi test menu and it appears like this
Will it be just software ??? If it is hardware to fried.
Thanks again for your attention and help me.
" WLAN state: disabled
Supplicant state : UNIINITIALIZED
SSID: <unknowmn ssid>
With shop ROM you never will be satisfied...
Change to EPIC or xiaomi.eu
Hi, im on the same boat as yours. My bluetooth died and i cant do anything about it. Did you finally solves your problem?

WiFi Problems

I am running Global 10.2. I got the phone on Saturday and since then I am unable to get wifi working properly. It will work for maybe a few minutes and then cut off. I have tried two different routers.
I am unrooted. Is there anything I can do apart from returning the phone or waiting until I can unlock the bootloader? TIA

I am having the same problem as you with my Mi9 very anoying works fine with the Hotspot shared from my Samsung S9+ but not all apps work via the home routers tried on 2 routers same thing MIUI update server is not reachable I also find Netflix doesn't work via home wifi from the MI9 but both Netflix and MIUI update work from the samsung phone hotspot netflix works fine from my other Android phones I own on my wifi though
Hope the fix this soon its very anoying.
Same problem for me : Wifi sharing is not working for all apps. It works for Chrome and Dropbox on my pc, but it seems some apps are not working. Those works with regular wifi. For exemple, nodeJS is not working fine.
Is the Mi9 blocking some ports ?
I got this problem too
I solve with set the hotspot band to fixed, 1 or 2.
But I have to set this every time I switch on hotspot.
Same problem
hi guys i m using the mi 9t and i have the same problem on 10.3.11, have you solved it or do u have any ideas on what is causing this stupid issue ?
happen to my mi9t today and i think it's kinda related to the co-ex problem between modem & wifi (problem not fix even rebooting the phone and restart wifi)
u can try the following step: settings-->wireless &networks --> more-->reset wi-fi,mobile &bluetooth
it works weel for me

Question Redmi Note 11 Bluetooth interferes with Wifi

Redmi Note 11
For the past three months, I am facing this odd situation where as soon as I turn Bluetooth on, the wifi disconnects. I have tried everything that I learned from Google and even reset my phone twice, but no solution so far. I have tried 5GHz wifi but still the same issue. I cannot use Bluetooth headphones or connect my phone to the laptop or smart watch while connected to wifi. I bought this phone in February 2022. It worked fine for a month and then this problem started. Please help.

If you haven't physically damaged your smartphone, then my guess is that you are experiencing a software (driver) problem -- in that case you have 2 options:
report this issue to Xiaomi & wait for the next MIUI release,
install (after unlocking the bootloader) a custom ROM (replacing MIUI) -- you can choose whichever you like:

a custom rom won't fix it i guarantee it , its a hardware issue . ive had the same problem with various devices over the years , phones , tables and laptops . the wifi and bluetooth signals interfere with each other . try putting your wifi on 2.4ghz bands b / g and see if it helps
I tested your issue twice just now. Connected the phone to a 5Ghz Wi-Fi then turned on the Bluetooth, after that I it paired with a sound system. The Wi-Fi never disconnected during the process. Maybe you have too many wireless devices in your area. Do more tests in a different location. Try flashing a different version of MIUI global if the issue persists.

Tried every solution, including moving Wi-Fi to 5GHz, but the problem still persists.

Surprisingly your suggested solution was spot on. I had two smartwatch apps on my phone (one for Haylou, and the other for the Mibro smartwatch). I uninstalled both, restarted my phone and turned on both bluetooth and wifi. No more disconnection issue. Now have to figure out which app is actually causing the problem. Before your reply, I posted my problem on many forums and searched google, but no effective solution till your reply. Thank you very much.

Thank you for your reply, brother. But how can you test my issue when you don't have the problem in the first place? Regardless of which network I am using (home, office, friend's house) and on which band I am (2.4 or 5.0 GHz), as soon as I turned on the Bluetooth, wifi disconnects. Swapon88's suggestion really worked. It was the smartwatch app.

Alhamdulillah, happy to hear that.
Brilliant. I was having this issue and uninstalled "da fit" app and it's fine now. Thanks
I am also facing a similar issue. When I am connected to Wifi and Bluetooth simultaneously, wifi disconnects after a few minutes and no Access points shows up in the available networks section. Wifi reconnects when bluetooth is turned off.
I dont have any smartwatch app installed.

I think it's common problem when connecting to a 5GHz Wi-Fi and using Bluetooth at the same time, it kept happening to my RN9 too

Yup, that seems to be the case. Can confirm such 'issues' happened on my moto g3, moto g5 plus, rn8 too because of interfering frequencies that causes either Bluetooth or wifi to disconnect (shortly).

Question Samsung Gears S3 keeps disconnecting

Hello everyone!
Got my Note 12 Pro a few days ago and biggest issue I have is with the bluetooth connection.
It paired with no problems, I have the Galaxy Wearable app and the plugin, it works fine for a bit and then randomly disconnects. It can work for 10 hours or disconnect 3 times in one hour.
Noticed on some other forums people complaining about bluetooth issues on other Xiaomi phones.
The watch, app and plugin are all on the latest version. The app has all permissions and zero restrictions on battery saving.
The phone is running MIUI Global 14.0.8 on Android 12.
I tried AVRCP 1.3; 1.4; 15 (default) and 1.6. MAP 1.2 (default); 1.3; 1.4. Switched between them trying every combo, none of them is stable. It never tries to automatically reconnect.
The watch worked flawlessly with my Moto G8 Plus. Sometimes it would disconnect (maybe once a week), but it automatically reconnected in a matter of seconds.
Has anyone figured a solution to the problem? I'm assuming I'm not the only one who has this issue.
Thank you!
Same problem for me, miui 14.0.2 on android 13.
Poco X3 pro.
No idea what to do...
Fixed the problem with a new phone. Got a Moto G73, the watch stays connected like it should. No trying to say something bad about the Xiaomi, I really liked the hardware of the phone, it's really good "bang for buck", but the Bluetooth and other small nuisances in the software made me go back to Moto.
