EMUI 9 WiFi randomly switches off - Huawei P20 Pro Questions & Answers

As stated in title my WiFi randomly switches off even while in use. I'm on .163, L29 and have nothing modded or rooted.
Anyone have similar problems?
If it does matter: it's a European device.

Have you checked if you have enabled the Wi-Fi + option? it seems exactly the behaviour of that option

It's enabled but it not only switches, it turns it off so that it doesn't connect automatically again.
Didn't has the behaviour on EMUI 8

Well, that's not entirely true. It also stores the location of known WiFi networks and enables the WiFi again when you come to that location. So there might be something wrong when it stores the location or your phone location get updated by network and not GPS.
See what happens if you disable the WiFi+

Maybe I should factory reset my phone, didn't do it for the firmware update so far..
Right now it works, it's not very repeatable

So, did you turn off WiFi+ or not?

WiFi randomly disconnecting on .575

Hello,
I recently flashed .575 on my Z3C, now WiFi connection is unstable, disconnects after a while. The consequence is that updates do not work correctly, file transfers through WiFi are often interrupted. Did any one notice the same behavior? Any fixes (tried different AP and to reflash the FW)...
Thx
Problem persists in 23.5.A.1.291
Similar issue here
I also have problems with the latest 23.5.A.1.291 firmware. There are two problems in fact, sometimes it disconnects and can't reconnect anymore without rebooting and the other is that, while it still seems connected to wifi, it's effectively offline as internet doesn't work anymore, after a while it starts working again.
It's a pity because the Z3C was the device with the best wifi and coverage that I've ever tried with the previous Lollipop. I partially resolved the problem, meaning that it happens less, changing a few parameters into the router, disabling every possible feature, still isn't completely resolved...

I'm not OP, however I tried that setting but it didn't improve much. After all, DHCP is a protocol which should be used only at connection startup theoretically
I also have the same issue, however installing Auto Wifi Manager seems to have helped -

Already tried but it didn't helped. As for the issue, for me it disconnects and reconnects instantly even with full signal every 5-10 min. So it does not eat my mobile data however every lengthy file transfert by wifi might be interrupted.
Tried different channels, 2.4ghz, 5 GHz on two different routers at home, on several public Wi-Fi AP, behavior is still the same.
If screen is on the connection stays but is sometimes interrupted and reconnects directly. If screen is off Wi-Fi gets cut for 2-5 min then reconnects (according to logcat, might be Doze? Wi-Fi is set to be always on). Tried also a full reset of radio settings.
Solution
Does not work unfortunately.
I might have a good news for you guys. I think I finally managed to solve the issue:
1) Download a Lollipop FTF
2) Open flashtool in Flashmode for this FTF and exclude everything except packages beginning with AMSS* (it will not alter any data on the phone and it's very quick, also does not need to regenerate the dalvik cache)
3) Flash
-> You just replaced the baseband / modem with the Lollipop one. Tested briefly on mine and so far no disconnections
Same problem here, after update to .575, and .291 didn't help.
Sometimes when I open WiFi networks phone doesn't find any network at all. Also bluetooh is acting weird sometimes (disconnects, can't turn on).
Tried with DHCP and clearing radio settings, and even downgrading to 23.4.A.1.264 and 23.1.A.1.28, didn't helped.
May be it is hardware related... I am on 4.4.4 and have same issues. On some routers better, on some worse. Also sometimes works ok for long time, next day same place disconnecting...
In my case, everything was OK until upgrade to MM

For me downgrading to Lollipop 23.4.A.1.264 solved the issue but as soon as I install Marshmallow, even a clean install by PC Companion the problem reappears. So I will stay on Lollipop for now, it also has Stanima
I think something is wrong with the way Marshmallow manages the WiFi connection

you're right. but luckily this problem can be solved! go to Developer options in Settings and check "Use legacy DHCP client". then reboot your device - problem solved!

Disconnecting WiFi

Hello,
I've used my Mi A2 around 2 weeks now and I'm really satisfied with the phone. However, I got some annoying issue about wifi. When the signal strength of wifi is not so strong (below -70 dbm), it tends to disconnect for around 10-20 sec and then reconnected again. This happened to me like 10 times since I got the phone. And wifi works perfectly without disconnections when the signal strength is strong enough.
Does anyone experience this issue? Or I got a defected device?
Thank you
Same here, sometimes it just disconnects ...

It is a normal stock android behavior, because android detects that signal of wi-fi is to low, and tries to switch automatically to GSM mobile data, or to another wi-fi if it is available in the area.
I don't have this happen but wifi signal is strong and also; gsm data is turned off.
That *may* help to turn that off possibly, as it obviously can't (now) switch to it?

Even if mobile network is off? Is there a way to change such behavior? I tried to find in the setting but what I just found is Aggressive WiFi to mobile handover, which was already turned off.

I think that it is called smart wifi, or wifi+ option in other types of android OS, and here it is just a automatic option in stock android i guess.
I don't mind it, because it will change my wifi router AP if it get stuck, and need an reboot, so it will automatically switch to another closest one that works.
You better think of some way to get a better signal then to turn off this function.
Try with aps like this on the link.

The thing is that wifi also disconnected when there's no other nearby networks to switch to. I did something to get better signal in my room but this still happened sometimes.

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.

Havoc 2.9 auto turn off wifi

I am using havoc v2.9 in redmi 4x.
Wifi is always auto turned off after screen is turned off.
It is not turned off immediately but it will be after a moment. If I turn on screen, wifi is back.
Therefore, I can not download file if screen is off. It will be stopped.
Anyone know how to keep wifi is always on?

Sorry for late reply, Yes this i was talking and also the settings which are available in settings > havoc settings > battery savings. under suspended actions there is option to switch to 2G when screen is off (not sure if it is causing the issue) try to turn off that.
i have one issue that when i move out of saved Wi-Fi network and comes back to to same network, the Wi-Fi does not get connected automatically until i wake the device and this happens to all my saved Wi-Fi networks. (Wi-Fi is always turned on my device in day time, it is off in night or when not needed)
it should connect Wi-Fi automatically to saved Wi-Fi network(s) when i have not turned off Wi-Fi from my device before going out of the range of Wi-Fi and later coming back to same Wi-Fi network.
rather than this i do not face any issue with connecting Wi-Fi once i connect to it, even after locking the device or restarting the device.
it only does not get connected automatically when getting out of the range and coming back. it requires to wake the device once and it remains connected until i am in the range. after that i must need to wake device just once to connect.

Question Wifi turn off itself...

Hi,
After a while, as soon as I am out of wifi coverage, the wifi turn off itself without me doing anything.
Once back under wifi coverage if I must think to reactivate wifi else I needlessly consume my mobile DATA ...
What to do?
Thank
Some android apps causing this issue ! Find it and remove it.
Hi, I would suggest to remove your WiFi connection from your phone, restart it twice and reinstall it, including network name and password. Maybe that will solve your problem. Regards, kuzibri
Do you have this option enabled?

Did you ever find a fix for this? I'm always forgetting to turn it back on, and using loads of mobile data.
This problem might casusing due to some application which is conflecting with wifi settings. advice to re install the applications and then test. Factory reset can be done after this step. Thanks

Thanks for the replies. But these solutions seem to be for a different issue, they have the WiFi randomly disconnecting. The issue I have, is the WiFi turning off, as in the WiFi toggle is turned off, it connects fine and is stable when in range. But when I leave range the toggle changes to off. I'd a assume it's either a bug, or a battery saving feature, but regardless I don't want to have to toggle the WiFi back on everytime I come into range of my WiFi.
