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.

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?
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
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.
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.
