[Q] Note 2 Won't Receive Data Packets on WiFi!!??

Hi all,
I recently sent my phone in and got it back probably little less than a week ago. Samsung had to replace the motherboard on my phone as it had the infamous SDS syndrome. I just realized the other day that when I connect it to WiFi at home, I can't upload my apps on the Play Store. I can still surf the web and everything, but most of the apps just don't connect to the web.
Is there a solution to this or do I have to send it again? As you probably know I don't want to do that because it's extremely frustrating. Should I try doing a reset to see if this helps the solution or ?
I know that it worked on another WiFi hot spot (my work) on Friday, so this issue just happened recently. I'm pretty tempted to do a hard reset since I don't have everything downloaded and reloading my contacts won't be that big of an issue. Any recommendations will help. It also states that my WiFi download speed at home is 72MBPS when I check the network I'm connected too.
Many thanks in advance for the help!
EDIT: I have not rooted my phone and don't plan too anytime soon. I'm considering on selling this so I can get the Note 3, but after the couple of issues lately, not sure if I wanna stick with the Note at all.
EDIT 2: Weird, it seems like it works in my room but not in my living room...I just realized that now which is extremely annoying, any solutions or suggestions as to what might be causing this?
EDIT 3: And it's not working again...I cancelled the download and tried downloading it again and it works again! This is frustrating....any help would be appreciated!

Issues with apps over WiFi after upgrading to Android 9

Hi. At the start of December, I upgraded my Mi A2 Lite to Android 9 and ever since then I have been facing issues with a few apps over WiFi. The following apps are being affected:
- YouTube
- Twitter
- Facebook
- WhatsApp
- Chrome
*These issues are only on my WiFi. On 4G or any other WiFi these issues don't happen*
The issue with Facebook and Twitter is the same. Both won't load any new feed and behave as if my WiFi is not turned on. YouTube only works at times, other times it would just keep loading and nothing would happen. Sending images or videos on WhatsApp is impossible now. It even has troubles making the backup to Google Drive on my WiFi. As for Chrome the issue is that sometimes even though WiFi is turned on, it would not load any page and just say that I'm not connected to internet. I've been reading other people's threads online and even emailed Xiaomi and Google. I tried the steps (hardware test etc) as told in the email by Xiaomi but that has not helped. Some said that using WiFi and Bluetooth at the same time caused this issue but I have used WiFi with bluetooth turned off yet the issue is still there. Now if this was a WiFi issue then I would have contacted my provider but with the same WiFi connection I have not faced a single issue on any other mobile devices and laptops. As for my WiFi I can't seem to change it from ipv6 to ipv4 (or I just don't know how to). If anybody has faced this issue and knows how to solve it then please help, It would be greatly appreciated. Thank you for your time.

Have you tried disabling Bluetooth and then reconnecting to the WiFi in question? Having both enabled at the same time causes WiFi speed transfers to be really bad, it's an already reported Pie bug.

Btw, can u see 5ghz wifi networks?
Cause i can and have same problem with slow wifi+bluetooth

Yes I have turned Bluetooth off and used WiFi like that but the issue is still there with all the apps mentioned

Any update on this? I'm having the same issue. Using a VPN seems to solve the problem but the connection is slower.

I am facing the same problem on my A2 lite Android One Pie. Even the further upgrades including March upgrade did not resolve the issue. It really sucks.
Has anyone found any solution?
Is MI even concerned or acknowledges the issue?
Is there a way to go back to Android 8?

Hello Dear Sajid Abid,
Good Day !
1st Remember One Thing. Downgrade Is Not A Easy Task, Downgrading Has Also A SIM Issue Problem,.But If You Still Want To Go Back Your Mobile Device From Pie To Oreo You Need To Unlock The Boot-Loader (Off-Course Unlocking Boot-Loader Will Void Warranty) Then Download Stock Oreo (From MIUI Forum) And Flash It With The Help Of IMFlash Tool. After Successfully Ported The Stock Oreo Rom You Can Close The Boot-Loader.
All Instructions/Steps Can Be Easily Found On A2 Lite Forum.
Here Is The Link Which Can Help For Resolving SIM Issue Problem.
https://forum.xda-developers.com/mi-a2-lite/help/sim-card-issue-downgrading-pie-9-0-t3874350
Have A Nice Day.
Thanks,

Mobile data sucks after updating to pie

Hi guys, since I updated my mi a2 to pie, I'm really suffering from the very slow data connection, even after February update!
I'm trying every possible solution but with no success
Anyone facing the same here? Any suggestions?

Facing similar problem also.
Though many times the phone shows the 4G icon, the bandwith seems low, especially when i try to listen to music through spotify for example, while it used to be better under Oreo.
Any solution welcome.

Any solutions? ?

Make sure apn settings are right I couldn't get picture mail right out of the box and when I went to tmo they noticed a . Was in the wrong spot

Redmi Note 8 very Slow mobile data

Hi, recently a suggested my dada to buy a Redmi Note 8, today he told me he can't watch youtube videos, i checked his phone and it is connected to 4G but the internet speed is realy slow, i did a speedtest and it is reaching 2 mbps max, i tried some solutions proposed to redmi note 8 pro but nothing works, we are in Mexico and the phone was bought here but it came with india rom, i tried to flash the global rom for test if it solves the issue but i cant, its older than the india rom running on the phone.
He cant connect his pc over wifi zone neither, it says connected without internet access.
Does anyone have a suggestion? plz help me, he wants to kill me
P.S. Sorry for my bad english

I have the same problem, no solution yet.

Aggravating!

Same issue here. I have noticed if I go in to airplane mode and back out my data isn't bad for about 45 min. Also my phone is a clean setup, I did not recover from backup and my phone has the bootloader unlocked. I only have a handful of apps on it.

Strange! You guys purchased from official store? Cause, no connectivity issue here at all. Check xiaomi authentication online. Check my speedtests:https://paavelo.tumblr.com/post/631930203952824320/speedtest

Please check again after you disable the gps and bluetooth...
And do it not from the drop down curtain, but from the menu...

Question Problems with mobile data - Stop working but looks good

Hi,
I own a Xiaomi 11 Lite 5G NE. I have updated to the latest MIUI Official V12.5.8.0.RKOEUXM.
From the beginning, I'm facing the issue that mobile data is not working. You're navigating and suddenly all stop and finally it shows the error no network.
After restarting is working fine again but it's very annoying. I've been looking for help but nothing found has helped.
Is anyone else facing this issue?
Thanks for your help and time!

Post seen by 26 people so far and no answers.
I suppose then mobile data is working fine for all of you... Mmm... My bad, it looks I will need to use the guarantee...

Hey. There
For some Days I also having mobile data problems. My phone så browser says No internet connection..
When i turn phone off or disable mobile data off for 30 min IT Works for a short period, then IT stopps again. I can use Wi-Fi at home.
I have factory restored my Device but its didnt helped. Swiched to second sim slot and nothing..
Gould be cool od someone knew how to fix it. Or need to send it in. Had this phone 3 months .
Specs..
Xiaomi 11 Lite 5G NE
MIUI 12.5.7.0 stable
Model 2109119DG

Same problem here. I'll preface this by saying that I work in a place where the reception isn't great, but with my old Huwaei it never happened.
When I lock the smartphone and then unlock it after a while it shows 4G+ but in reality there is no connection.
Last night at the gym (in a basement where the reception is zero) after I left it wouldn't pick up the network again.
To solve it I have to put on and take off the airplane mode.... Very very frustrating.
I also replaced the sim card with a new one but no dice.
MIUI 13.0.5.0 Stable

Thanks all for the replies.
So I'm not alone, but it looks that some people have not issues.
Looks also problem is on MIUI 12.5 and also on MIUI 13.
I think it is a hardware problem, not software.

In these days Ill take it in assistance and I will update you.
Unfortunately, it has been too many days since my purchase and I can no longer return it. Super regretful that I didn't get a samsung a52s!

Need to that we had igły weather here with lightnings and storm . Many trees was Tilted.
But checked mobile operatora site and nothing there.

Hey again.
I have talked with my phone carrier..

They should have write something on their homepage. Will have helped , so I didnt had to factory reset.
That's All for now.. Have nice weekend you All.
Hope you will have yours problem fixet.
Bye

I also had major issues with my mobile network on 1 of the simcards. (I am using dual sim)
If your provider supports 5g then call with the dialer *#*#4636#*#*
you will see a menu with 3 options. the first selection is simcard 1 the second simcard 2.
change the prefered network type to NR / LTE / GSM /WCDMA or whaterver ur provider is supporting, NR = 5G network.
Make sure you disable VoLTE for both the sim cards since this was disabling my download from mobile networks.

hi guys, yesterday I took my cell phone out of repair. They replaced the motherboard and now it seems to be working fine, no signal loss.

Hi @ddanielee , that's a great news!
Is it still working since then? All fine?
Did they say something if this is a common issue?
Thanks for your comments and feedback!

Hi Raulci, i replied u in the other thread!

Just wanted to let you know that during the last weeks, I haven't experienced any other mobile data issue again. I have changed anything. Let's see if it continues this way.

Yes its a problem. Initially i thought its miui 13 problem. But reading above comments with slow speed/ 4g connectivity issues in 12.5 it seems its hardware related. Inferior modem or low quality antennas could be the case. I was hoping to fix by reverting to 12.5.

Same problem i have mi 11 x i even go to the service centre they factory restart my device and it's not fixed they said it must bu hardware problem
