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.
Hi:
My S21 Ultra is the T-mobile variant, in the US.
The Wi-Fi advanced setting for "Switch to mobile data" is nonfunctional, because it has no effect when turned on.
I'm hoping that others can verify this problem: When you are connected to a non-functional Wi-Fi signal (e.g., your phone displays an exclamation point (!) next to the Wi-Fi signal strength indicator), your phone should still be able to access the internet by switching to mobile data, when you have this advanced setting turned on.
However, with my phone, I *CANNOT* access the internet when I connect to a non-functional Wi-Fi signal, whether I turn on or turn off the "Switch to mobile data" advanced Wi-Fi setting.
I'm hoping others can confirm the same issue, so we can escalate as a bug that Samsung can fix. Or maybe somehow it's an issue specific to the T-mobile USA variants of the S21 Ultra?
Anyway, I'm guessing most people don't encounter this bug, because usually you are on a functional Wi-Fi signal. But in my situation, I *NEED* to be able to connect to a non-functional Wi-Fi signal, and access data through the mobile/cellular tower connection. The reason is because that's the only way I can update the firmware on my dashcam. My phone connects to the dashcam via Wi-Fi. That works, and the app can view the dashcam etc. But the app also needs a data connection to download a firmware update for the dashcam. But when I'm connected to the dashcam via Wi-Fi, the dashcam does not provide internet. So I'm stuck because the S21 Ultra *WON'T* access the internet when connected to the dashcam via Wi-Fi, because the "Switch to mobile data" setting does not work and is ignored, so the phone has no data connection whenever I connect to my dashcam.
I figure, if T-mobile doesn't allow this, then they should remove the setting as an option. Why include the setting if it's simply ignored and nonfunctional?
There are some added wifi settings in the developer mode like, wifi scan throttling and wifi safe mode, have you looked into these? I don't have any wifi problems on my S21U unlocked phone, not branded.
In my developer options, Wi-Fi safe mode is off, and Wi-Fi scan throttling is on.
But the issue is my phone refuses to connect to cellular data, even though I tell the phone to please connect to cellular data when the Wi-Fi is unreliable.
I'm not sure that the Wi-Fi specific options in developer mode would cause the phone to refuse to connect to cellular data.
Are you able to connect to an unreliable Wi-Fi, and test whether your phone can automatically receive info via cellular data *WHILE* you are still connected to the unreliable Wi-Fi? You can simulate an unreliable Wi-Fi if you have a modem connected to your Wi-Fi router, and turn off the modem but leave the Wi-Fi router powered on with no internet.
Also, can you check your developer setting for "Mobile data always active"? Is that on or off for you? I don't want to turn on that setting, because I want the phone to save battery and turn off mobile data when I'm connected to a reliable Wi-Fi. The notable setting for me is in advanced Wi-Fi, where the phone can "Switch to mobile data *ONLY* when the Wi-Fi is unreliable and doesn't provide data.
