10.1 wifi issues?

So loads of 8.4 users have been complaining of wifi issues - has anyone been experiencing wifi issues on the 10.1?
You would assume they use the same wifi antennas..
i havent put there is also a software update available right now that might fix some things.no info has been found yet on what exactly it does.
I'm on a 10.1 and haven't come across any issues yet
I've had the device since day one and haven't experienced any wifi issues, either at home or at work.

No wifi issues here. My tab 10.1 locks on and stays on.

What kind of issues are you talking about ? I'm having major wifi issues with my 10.1 NOT LTE. Wifi keeps disconnecting every 10 minutes. I tried:
In my router:
- Disabling MAC filtering;
- Tried using both DHCP or static IP;
- Using Wifi G only (instead of N);
- Disabling B/G protection;
On the tablet:
- Same issue with stock ROM and custom ROM;
- Same issue with stock kernel or custom kernel;
- "Wi-Fi Timer" option is OFF
- "Keep Wifi ON during sleep" is set to ALWAYS
- Turned off Avast! & Malwarebytes (just in case)
It's major pain because I can't play any games reliably. I can't send back the tablet to Samsung because the KNOX warranty is void.
Anyone has any idea or is having the same issue ?

[Q] Weird Wifi Issues - Zombie Mode

Hello,
I am having some rather particular issues with my Note 2.
About 2 months ago the GPS just wouldnt work. If you tried to turn it on it would crash the UI or OS .
I have been running Syndergy Rom r85 for over a year at this point and not serious changes to the phone ina while.
So I did a nandroid and started to tinker, a clean flash would fix the GPS issues.
So Backed up some apps and misc stuff and wiped the phone and reinstalled Synergy.
Every was peachie except for the following :
Using Wifi Tether V3.2 B2 M5 *Synergized its getting killed as the Wifi auto on's of its own accord.
Its not just when I tether I now have to check it throughout a day to make sure its not on. It isn't auto connecting to what it finds unless it is a network I have connected to before.
The only thing I am not 100% on is if I was running that version of the tether app.
So, is there a way to figure out whats turning my Wifi on? Is there a newer version of the tether app that will work with my N2 on a 4.1.2 ?
Thanks for any help

Paranoidandroid WiFi drops

Hi guys,
I'm a new user and I can't post in the pa thread. I am having constant WiFi drops on paranoid android 4.6 beta 2. The WiFi will work for 5mins and then net connectivity drops. Disabling and enabling WiFi fixes it for another 5-10 minutes before it drops again.
Anyone else faced this issue?
Are there any solutions or is this a known bug? Otherwise this ROM is perfect for daily use and I love it.
Please help!
Thanks.

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.

Have A Nice Day.
Thanks,

WIFI Fix

Like a lot of you guys I've been struggling with my WiFi to update Twitter / Facebook / Instagram and so on but I've found a little trick don't ask me how though ..
Seems when having a VPN activated the WiFi works normally but as soon as you forgot to turn on the VPN even Gmail and OS updates don't work
Some infos that may help ? :
I'm located in Algeria everything was ok on Oreo
Installed VPN and Android Pie update popped
Download it and applied it since then WiFi is broken
This issue is only on WiFi on 4G/3G everything is ok
Bluetooth issues when pairing Redmi Airdots you know the drill
Thanks for sharing your thoughts
