Wifi issue on my TAB A7(Wifi only) .

[Aryanpro03]

I bought my Tab last month . I use my tab by connecting it to my phone's Hotspot (Realme 7) .  But the connection is never stable , It disconnects randomly and when I try to reconnect , it says "Authentication error  occurred" , even when the password is same . I went to service center yesterday , they reloaded the software  , the problem is still there , But this time wifi doesn't disconnect , instead it says "connected without internet" after random time . Didn't expect this from Samsung . 

Here are some settings which I have already tried , but toNO SUCCESS .

1) Automatic Date and time is on already . (As mentioned in some YouTube channels) .

2) I have tried resetting network settings . Even factory reset didn't help .

3) I have tried changing randomized MAC Address to Tablet MAC .

4) I have cleared cache partition , performed soft reset and forced reboot .

5) I have entered into Safe mode too , still same problem .

6) I have tried turning off "Google location accuracy" , as mentioned on some sites .

7) I have turned off "Put unused apps to sleep" , still no help .

8} I have already sent log files twice . So DEAR ADMINS , PLS DON'T TELL ME TO SEND IT AGAIN.

9) Smart Tutor technicians just cleared the data of wifi and hotspot app and told there's nothing wrong with the settings .

All the steps above fix the issue for a day or two , but thePROBLEM COMES BACK AND IS STILL HERE . There's no issue with my phone (Realme 7) , which gives Hotspot , as other devices in my home work fine with it .

I strongly feel it has something to do with the software . Please give me a fix or release a software update fixing it , as it hurts to see your new Tablet which has only wifi for internet connection in this condition . 

Date :- 22/10/21 PROBLEM STILL HERE .

Can you name the laptop and other android tabs plz

Done

Hotspot device :- Realme 7
Devices which work fine under this are Dell Laptop , Redmi Note , Jiophone🤣 and one smart TV of chinese brand .
I think China has something to play here , because all the devices above are of China

Can you suggest something about the Hotspot device ?

[ᗰOᕼᗩᗰᗰEᗪKᕼᗩTᖇI]

Ummmm but still can you try by sharing mobile Hotspot with another mobile
That will give us a confirmation and then I will be able to suggest tips

Maybe that's the case
I can trust dell and jio
But the other three exceptional lol

But still
To have a confirmation
Try with another device like a Samsung mobile and sharing mobile Hotspot and then using that with your tab.
