Huawei P9 - Wi-fi issue (randomly dropping off)

I experience this problem since I have the phone: The P9 Wi-fi randomly disconnects and then reconnects immediately (it can happen 5-15 times during one hour).
This is very inconvenient during large files transfers or when playing games that require a steady connection.
I have tried the following actions without any success (my router and phone firmwares are up to date):
- delete and re-add the Wi-fi network
- turn everything else off (e.g. Bluetooth, NFC)
- disable/enable "Wi-fi+"
- apply all different settings of "Keep Wi-fi on during sleep"
- disable Bluetooth / Wi-fi scanning under "location"
- P9 and router reboots
- force the connection only to the 2.4 Ghz / 5 Ghz router's network (with or without separate SSID),
- change the Wi-fi channels (to avoid congested Wi-fi channels)
- disable IPV6 on my router
- disable DHCP and connect with a fixed IP
- reset the network settings on the P9
- factory reset of the router and phone (what a waste of time...)
Meanwhile, Wi-fi is working perfectly on my Samsung Galaxy S6 Edge Plus and iPad.
Does anyone else experience Wi-fi issues with the P9 ?

I can only report that I have 0 issues so far, my wifi reception is strong and constant,even better than on my tablet.

Mine too perfect no issues.

Thanks for the feedbacks! After further digging, it appears that some marshmallow devices don't work flawlessly with IPV6 (at least with my router).
I saw afterwards exactly the same issue when a Moto E 2 connected to my wifi network.
I already disabled IPV6 on my router without success. I tried again and after changing this setup, I made sure to remove all connections ("forget the network") and reboot everything before reconnecting. It worked!
So it was actually a combination of the steps I previously mentioned that fixed my issue.

I'm getting a lot of disconnects, where the phone switches to a 2.4GHz connection or to mobile data but in my case it's an issue with the router - and I'm trying to work out if there are any settings that cause problems (it's an Asus DSL-AC68U with the latest software).
The phone itself seems to have excellent Wi-Fi and mobile connections, suggesting very good antenna design. But most Huawei made phones have good antenna design. My P8, despite being 2.4GHz only, was excellent for Wi-Fi. My Honor 7 also seems to be exceptional, as is the Nexus 6P.
Does make it hard to use another phone.

I am also having dropping WIFI problem. But it only happens when I am on 5ghz and when I am two rooms away from my router. I have a Asus RT-AC87U.

Mine use to disconnect too and I changed router to 20hz from 40hz under WiFi

I was at a telecom shop today and inside the shop they had wifi. Of all the wifi connected smartphones on Display the Huawei 8 and Huwaei P9 Plus had the best wifi connections with the strongest reception showing full bars while other smartphones were showing 2-3 bars for wifi connection reception

@desiregeek : Huawei 8, you mean Mate 8, P8 ?! I'm glad to hear that triple antenna implementation is one real upgrade , not just marketing ☺

Where did you hear that?

From Italian and spanish reviewers on YouTube (all of them said P9/plus is great for Wi-Fi and cellular signal), you just confirmed. I tested myself briefly in store and Wi-Fi range is a bit better than my Mate7 which is is very good for Wi-Fi signal strength reception.

Yes, it is my second post. The issue was with IPV6.

Bad experience with P9.
1. Ear speakers not good
2. WiFi catcher was very poor.
3. Keypad font not satisfaction.
4. Screen size should be wide.

Hi, Im having the same problem with my huawei p9.
Hi, Im having the same problem with my huawei p9. I thought the problem would be in my router but my laptop is working perfectly fine, but my p9 connects and disconnects frequently and disrupts my work.
Can you say again how you did with your p9 to fix the issue?
Looking forward to your positive response. thank you.

Rollback from Pie?

Yes you can, you need to unlock your bootloader, put your phone in EDL (fastboot oem edl) and flash the firmware with MiFlash

You can lock the bootloader in MiFlash, the option "flash all and lock" or something like that.

I had also updated my phone to pie using vpn and now there is some problem in my wifi range. Wifi doesnt work as good as it used to in oreo.

I also have serious wifi issues since I updated to Pie. Specially with 2,4Ghz band when i go to a zone away from the AP. Although the signal is still pretty strong, the wifi radio keeps connecting and disconnecting. It's very frustrating because it didn't happen with my previous phones and it doesn't happen with other phones from family members or friends, even if the devices are low end.

Settings > Wi-Fi > Wi-Fi preferences > Turn off Wi-Fi automatically

No, the culprit is not the wifi power saving feature. This problem is totally different and it only happens with the 2.4Ghz radio. Anyway the setting you say seems to be removed in Pie.
Edit: Problem solved.
It's this setting --> Enable Wifi automatically. I don't know what it does precisely because the name and description is misleading. I disabled it and wifi now works like charm.
Thanks for the clue!
Edit 2: Wifi power saving still works as it should, disables wifi when there's no net activity with device locked. So far, so good [emoji11]

That's WiFi AI, Android Pie is entirely based on AI predictions, it works great for brightness and apps once it's trained, but it's a pain when it comes to connectivity, it needs further enhancements.

Redmi 9C connected to wifi but no Internet

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

Question WiFi Problems

Hi community,
I'm writing because I have a strange WiFi problem with my S21 Ultra which I had with no other equipment before.
Setup:
- Galaxy S21 Ultra
- FritzBox 7590
- Fritz WLan Repeater 1750E (2x for better range coverage)
- WiFi 5G Auto channel WPA2/3
- WiFi coverage is good (tested with a lot of other devices)
Phone Setup:
- Paired with the WiFi
- Do Not use Mobile Data
- automatically reconnect to wifi
Problem:
The phone does not automatically connect to the WiFi.
The phone also looses the connection to the WiFi several times a day.
When the phone is not connected to the wifi I open wifi settings.
- It happens that the wifi list is completely empty and the circle animation indicates that the phone is searching for nearby connections
- It happens that the wifi list contains a list of wifi networks the phone has seen before when it was connected last to a wifi
- Switching off an on the wifi helps to find the actual networks and the phone then connects back to wifi (most of the time)
I tried already several settings and combinations but so far none of them brought any success. So I would like to know if someone else had a similar issue or has an idea what could go on here.
To me it seems strange that the wifi scan is not working as I would expect it. I would expect the phone to continously refresh the wifi list with networks it sees, but always when the phone lost its wifi connection the list is not working anymore.

Try tinkering with the wifi channels and encryption until it shows up.
Or you can try resetting the routers to see if it does anything

It is possible that your phone also gets confused with the router and the repeater.

- Phone is on standby (placed on a table, etc.)
- I turn it on to check messages,
- No connection to wifi
- Open wifi manager
- No wifi networks listed at all
I do not know why my router/network should be the problem. All other devices in the wifi work flawlessly. It cannot be that I have to restart my wifi router every time the phone finds no wifi at all. That makes no sense to me.
It looks more like the android wifi service is still on sleep and does not report new wifi networks (which would be necessary also to see any wifi at all).

May I suggest....
Settings -> Connections -> Wi-Fi -> (three dots it top right) ->Advanced
Make sure "Turn on Wi-Fi automatically" and "Wi-Fi power saving mode" are both off.
If you use a repeater is it a mesh or AP solution? I find Android will drag its feet letting go of a wifi signal even when walking into range of another known network. Had an extender in garden and even when down to 10% connection on Wi-Fi it would stay connected to extender, I had to turn wifi off and on quickly to get it to pick a better network.

Definitely try what lywyn suggested...

you can also submit an error report on Samsung Members app, it sends reports directly to Samsung and get the feedback.
Download the app from the Galaxy Store if you don't have it on your phone > Memers app > + button > Error report

sometimes it happen when you connect at certain locations.

If you haven't already done so give this a try. Settings, search "Wi-Fi", scroll down to Location, Improve accuracy - toggle on, Wi-Fi scanning - toggle on.

Mesh is a single network solution so should not be a problem.
The only other thing I can think of is the power-saving mode. My son has his Pixel on power saving all the time and I know sometimes he has to turn off/on wifi to get a connection when waking the phone up

I found the issue! It is WiFi Direct related. The app "nexar" from the dashcam is interfering with normal WiFi on this phone. Nexar conquers the WiFi functionality and is responsible for my wifi disconnecting. The app requires the "Location always" permission. If I remove this permission my WiFi works again normally. So: one has a similar issue: remove "Location always" permission from the nexar app. In my case it helped.

You said the phone loses connection and and many others. Does that show up best on the region you described, or does it also happen at different places?
Kodi nox
It is feasible that your phone additionally receives harassed with the router and the repeater.
1st you need to honestly recognize if the issue comes from the cellphone or likely from your WIFI devices. Once this is clean, you've got something to go on with...

MIUI 12.5 wifi issues

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...

My Xiaomi T10 could not connect only to *some* wifi, it has been so since when I purchased it.

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...

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.
