[Redmi Note 9S / Note 9 Pro (Indian Model) Question] dork997:
Hello guys I have recently purchased a Note 9s Global variant and it has the same wifi bug, loses connectivity when in sleep mode. I can't return the phone because there is no consumer protection in my country and the only option would be to sell the phone at a loss which I dont really want to do for obvious reasons. Its my first MI phone and this bug is making me question my purchase decision.

Can anyone using a custom rom please confirm if they have this issue or not? Have you checked your router logs to determine if you really don't have the problem or if the wifi is just reconnecting in sleep mode right after it disconnects....just like what Xiaomi implemented with 11.0.8 and 11.0.9? If you guys can confirm this there is atleast hope that this will get fixed at some point....otherwise i am not looking forward to taking a financial hit right now :( thats the main reason why I went with this phone in the first place because its cheaper, not everyone has the money to buy samsungs and iphones.

Regards

And I was waiting from February for phone from Xiaomi with 2 sims, dedicated slot card, and when the time approaches this to happen to see working Xiaomi redmi note 9 pro, I will wait but maybe will buy another model.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
Oh wow.

The cheaper, less powerful version Note 9 is getting the update right now, and for the better version there is not even a concrete release date?

That's really sad, Xiaomi...!
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] llinuxx:
And btw for those of you who wanna use Live View in Google Maps for navigation or etc you must know that Xiaomi Redmi Note 9 pro does not have ARCore certification for now.

You can check phones that have support.google.com/maps/thread/11554255?hl=en - see Redmi Note 7 nad 8 have...

Info about Live View support.google.com/maps/thread/11554255?hl=en

On xda u can find info how to get "certified" - I am not sure is it working cuz the info is from 2018 xda-developers.com/how-to-fix-device-not-certified-by-google-error

and do someone of u get proximity sensor problem ?

Anyway - maybe I will try Mi 10 Lite 5G - someone with same decision ?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
These are not problems with the wifi, please post those info in a thread that better fits ?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] dork997:
Can anyone using a custom rom (like evolution or other AOSP) please comment here? have you guys checked your router logs if the phone still disconnects and reconnects to it like Xiaomi's dirty fix in 11.0.8 Rom? or are those roms entirely free of this problem. This will help us determine if its a hardware fault (not completely fixable via update) or if they might be able to fix it properly in MIUI 12. Kindly share your experience here.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] simone982:
According to what a moderator of xiaomi community said, priority in bug fixing and version updates is not based at all on the value of the the device.

It's only based on report count from users, so in fact in popularity of the device, then if users are active to report bugs they have support. It is also suggested to report the same bug/issue more than once.

It sounds weird to me :eek:

That's interesting, I hope we will get a feedback from custom rom users
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] llinuxx:
YES IT'S ISSUE WITH THEi MIUI ROM

Short info - c.mi.com/thread-3025928-6-1.html post 54

More info:

I track WiFI problem from 10.06.2020 in mi forums - all of moderators just answer like bots.

Only the moderator with nickname happybuddhis give some "kitchen" info and is familiar with the problem.

So we are waiting.

And "we" know over the years, there has been a practice in xda users detect bugs and someone else take advantage/benefits but that's another topic
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] herpsnderpsn:
is the wifi problem fixed now? I'm thinking of buying the phone as a present, but not if the wifi does not work properly.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
Nope, not really fixed.

But they gave a "workaround" on actual FW as already mentioned in this thread ?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] fgendorf:
But isn't OTA for me... Still bugy
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
Well, what Firmware version do you have?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] dork997:
No its not fixed, in 11.0.7 and earlier versions they wifi used to disconnect when the phone goes to sleep mode. With 11.0.8 and above it still disconnects from wifi in sleep mode but reconnects shortly after that which is why most folks aren't noticing the problem but if someone checks their router logs they can tell the phone is still disconnecting.

Someone mentioned that non-miui roms do not have this problem but we aren't sure if they are like 11.0.8 (where the phone disconnects but reconnects automatically) or if they are actually free from this problem I have requested many times but no custom rom user confirmed / denied this. Someone in this thread also pointed out that this is due to a faulty hardware based cryptographic engine in this phone and can't be fixed with a software update maybe this is why Xiaomi has been deleting related threads in their community forum. Wifi connectivity is a basic feature and if it is not fixed / replaced for free I'd never buy a MI phone again (btw this was my first mi phone and it has been an ugly experience so far).
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] fgendorf:
I don't know why, but my phone is on 11.0.1.0
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
Well, normally then there have to be an update OTA for your phone, cause there have been several updates past the 11.0.1.0

[Redmi Note 9S / Note 9 Pro (Indian Model) Question] galaxy6220:
I wouldn't buy this phone to be honest. The wifi bug is still present as many are saying but after the 'dirty fix' it is better. The biggest issue I have is the well mentioned call dropping (both wifi and network calling) nearly every phone call I make gets dropped.

I bought this phone when it first came out and I've never felt the wow factor. I am also eagerly awaiting conformation of some kind from people using custom ROMS whether both these bugs are present in non Miui ROMS. I would flash a custom ROM in a heartbeat but many people are hardbicking their devices beyond repair. Apparently Xiaomi are making this more difficult too. Not good.

Would I buy another Xiaomi? I doubt it very much.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
Well, also the call dropping is a problem that not everybody has.

I'm using my phone couple of times daily for phone calls, and had NO call dropping so far.

So I think you can't say its generally not a good phone. ?

But also I don't wanna say that this is a must-buy-phone, a "no-brainer" and THE best phone out there today...just wanna say that not every Note 9s/Pro must show the known bugs. ??
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] fredikruger:
I am using this phone since one week with latest xiaomi.eu ROM.

No problems with WLAN deep sleep; whatsapp, signal and email notification within one second (I did a lot of tests because i am aware of this problem)

At home I use cable router from my provider, manifacturer is Compal Broadband Networks, Inc. It's not the german Fritz!Box.

Also network phone calls are stable, not any call drop within this week. Wifi calls i don't use.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] dork997:
I understand that you are not experiencing any issues regarding wifi functionality but have you actually checked the router logs?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
Yes, it's right that you could see the bug on the logs perhaps.

But if everybody is working, why the need to check logs?

Things are working, that's the main thing ? As long as everything is working, I don't care about router logs, to be honest.

But I understand that people who HAVE problems with their WiFi are becoming very angry that Xiaomi doesn't really FIX this issue (and it is definitely one of the MAIN ISSUES of the device, and I'm pretty sure they would sell more of this device if that would have been fixed already...)

I bet there are also many customers who will think twice in the future when buying a new phone, when they see that Xiaomi give a s*it about wide spreaded problems of their phones...
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] fredikruger:
It ist a simple DOCSIS Router without logging on the LAN and WIFI Interface. I only can see which devices are actually connected and their DHCP lease time - there is nothing unusual to discover.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] dork997:
Well I don't really know much about Xiaomi phones as its my first Xiaomi device. I have used samsung, apple, and lg phones in the past and each one had minor design/software issues which is acceptable there is no such thing as "the perfect device" my iphone 6 which I purchased on launch day died within a year to its famous hardware design flaw with the touch IC, Having issues/bugs in a new phone is one thing but not being able to fix them in 3 software updates is another.....even if they can't fix it they should release a statement or something so people can know for sure whats going on.

Secondly you are right about if the phone works fine why check router logs? thing is it does not work fine...if you use whatsapp web (which I use a lot as I run a small business and we connect with customers over whatsapp web its more convenient to be able to chat on a monitor with keyboard support) whatsapp web will randomly disconnect from the phone because the fix in 11.0.8 and 11.0.9 does not stop the phone from disconnecting it just reconnects it after the disconnect + it will be waking up the phone from deep-sleep meaning more battery drain....the average end user who does not use an app which requires constant wifi connectivity should not notice much of a problem....but the problem is still there and Xiaomi instead of fixing it / addressing it just continues to ignore it.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] eeeemc:
I understood your feeling..................

Not that I have this phone ( I bought one myself Redmi note 9 Pro 64m/6G/128G )

It's because 1 of my sim subscription ( I inserted twin sims ) at USD4.00/month as this sim with me since 10+ years so that I must need to keep this sim phone number. I experienced bad signal , call drops and so on.

I figure out SIM provider locate an inferior band for my subscription package. I noticed it as I also use SIM 2 make calls once the Sim 1 dropped my call ( and angry ) and I immediately knows the story behind. Note : the problem sim provide is the top number one provide in my area., just that they locate frequency base on subscription fees.

I understand why you angry as dropping call is seems a must to you ( I know ).

send back to official Xiaomi or use other ROM is seems the only option.

Thank you very much.

i was getting call issues but im in a dodgey signal area. iv turned off voLTE and no issues since. think it was trying to make phonecalls through 4g when signal is ****.

---------- Post added at 11:17 AM ---------- Previous post was at 11:12 AM ----------

the wifi issue is better with the newer update as in dont have to toggle wifi off and on any more. the only time the issue is apparent is with whatsapp web which will loose connection occasionally. that issue never happened on my lg g3 which this redmi has replaced.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Qamarfk:
Hi,

I just purchased Redmi Note 9 pro global, QJZIDXM, I am facing issue that WiFi internet stops after some time of screen off, all my downloads stop. I am still having this issue after latest update to Indonesian rom 11.0.3.0

Please help and reply till when it will be resolved.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] dork997:
Unfortunately it is still not fixed in the latest update 11.0.10 for the Global variant and it has been there ever since the phone released. So they have released 7 updates and the issue still persists...firmware 11.0.8 and above kind of provide a dirty fix for this by forcing the phone to reconnect when it loses wifi in sleep mode, the wifi still disconnects but it reconnects after a few seconds (most users wont even notice this unless they are checking router logs) this is a dirty fix which will impact battery life, to be honest with you it seems like a hardware issue and this "dirty fix" is as good as its going to be. So either get rid of the phone or update to 11.0.8 or above if you are okay with having a faulty phone me personally I am never buying a xiaomi phone again, this was my first and last xiaomi phone.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Qamarfk:
But I think it's not a hardware related issue, as WiFi works awesome when screen is on, never disconnects, hope it will be fixed in upcoming firmware updates, may be in miui 12.

[Redmi Note 9S / Note 9 Pro (Indian Model) Question] slybunda:
as advised before, this is a hardware issue to do with the wifi modules sleep states. its not an issue that can be fixed without serious loss of battery life.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] fgendorf:
Well, mine global Europe version qjzeuxm, the update from 11.0.1 to 11.0.3 stops wifi issue
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] dork997:
Please go through the thread, these updates do fix the issue to some extent but its not a proper fix. The wifi still disconnects when phone is in sleep state but it reconnects shortly after that ... anyone who uses an app which requires continuous wifi connectivity to phone will be able to experience this, for example whatsapp web (if you use it for hours) will randomly show "reconnecting to phone" which means the phone still loses connectivity but connects to wifi automatically (which takes a toll on battery with constant wake-sleep cycles)
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] MSK1:
Is this issue affecting every phone or just 10% of them?

Trying to work out if it's worth taking risk?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Zasnizas:
I don't think this issue affecting on every phone because mine is working fine out of the box, I mean from day one I bought this phone until now for almost four months I used it and I don't face any issue with WiFi. I can receive emails, whatsapp etc without any delays and yes I already check my router logs every two or three times a day for about three days and all are fine no errors. BTW mine is curtana I bought it from xiaomi Malaysia official store
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Smartie083:
This is an interesting observation. I am looking at buying this phone but waiting to see what is happening with the Wifi. The model being sold here is also the Redmi Note 9S, which I believe is the Curtana one. If someone with the curtana also have the Wifi issue, would you please let us know?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
Yes, Note 9s has this issues as well.

But as I already wrote, mainly is this problem in combination with fritzbox routers.

And it is "fixed" so far that the device will disconnect and connect again directly, so many people won't notice the problem any more, push noticitaions for example are working without bigger problems.

Before this "fix" wifi has disconnected but you had to reconnect it manually.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Smartie083:
Thanks! I think most of the time it will not affect me, but sometimes I use apps and things that needs constant networking and even a quick disconnect and reconnect can affect certain processes and make things like file copying fail. From my research this looks like a hardware problem and if that is the case it will not be fixed completely. I don't buy a new phone every year, so I need to know that I buy a reliable device. Really hope that it is software and that it will be sorted out soon!
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
Well, if you use this apps with display on, there won't be a problem. If screen is off while using those apps, it could be that wifi connection is cut for 1-2 seconds every now and then.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Smartie083:
Thanks for this information. I am just worried that it may prevent some of my workflows in future, like copying a file to or from my file server. I would not keep the screen on but big files will probably always fail when such disconnections happen. Same thing when downloading big files from the internet. It may keep it from disconnecting but I don't want to take the chance.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] skezza:
I noticed some weeks ago that my Wi-Fi issues appear to have got a lot better, so I decided to check my router logs and they look fine. Connect at the right time and disconnect at the right time. Maybe the one of the last updates has resolved this?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Smartie083:
This sounds like great news! I would be so happy if this is the case. Thanks for posting.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Joshua Victor:
which ROM version are you using now?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] skezza:
The latest. 11.0.10

To be clear, I had problems when I first got my phone. It was suffering from the disconnect issue hence I gave the MacroDroid idea which was fine for a few weeks. I then got the update to 'fix' WiFi. For me, this only partially fixed it. I don't use WhatsApp web but I found Yatse the Kodi remote would often say the Wi-Fi wasn't connected even though it was. So this remained an issue

Those issues have now disappeared. Yatse works every time and the whole phone is getting a lot more stable. I'll probably factory reset before updating to MIUI 12 when it comes.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] blowy666:
Normally, there won't be a disconnect while there is a data transfering and the screen is off.

Only when wifi is on "idle", it will disconnect from the router in some cases (on some router models), as far as I read. ?
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] llinuxx:
So with the latest news

c.mi.com/thread-3248131-1-0.html

and the HOT NEWS IS

no Galileo GPS support

since I use phone in Europe and Galileo is the best option for Europe - check info - en.wikipedia.org/wiki/Galileo_(satellite_navigation) - so bad, so poo marketing this time from Xiaomi

I will not buy it even they fix all problems with the wifi in MIUI 12 and camera problems with panorama pictures, and many more.

Similar frivolous marketing tricks with this phone and these problems will definitely affect them in the near future.

Users have been confused by the different names of the series for different parts of the world, and apparently the developers themselves are confused because they did not add Galileo, separately Xiaomi everywhere advertises the phone with the option that there is Galileo. Gsmarena many times denounced the names and specifications, although I wrote to them several times, they do not fix anything. Separately with the camera sensors is the same confusion.

So good luck with the phone to all, especially those in Europe.

Group Key Update is disabled, that's why you don't see reconnections. This bug is related to Group Key Update handling.

You can do a test, if you want. Set Group Key Update to 60 that is 1 minute, check that you are connected with your smartphone, then put it in sleep mode. Wait for 1 minute and you will find a reconnection/new dhcp client request in your router/ap log
