WIFI - Begging for help!

[vlad_8011]

Hello. Im here after wasting above month on official MIUI and Google forums. Xiaomi never answered, and Google is telling me "this is not proper thread" everywhere, and it looks like they have no support for my phone.

So problem is, after upgrading to Android Pie, my wifi stopped working for Youtube, Gmail and System Updates. Those 3 Necessary apps for me need to, MUST work on wi-fi.

What i have done so far:
- Changed router
- Wiped phone (at least 9 times)
- Flashed Official rom from MIUI page..... (few times)
None of them worked plus i got another problem. After flashing Android 8.1 from miui, my sim slots have swapped in system - now sim 1 is sim 2, and sim 2 is sim 1. I knoew it may happen, but even on 8.1 wifi have not fixed itself, so i doubt its something with device, but with some drivers.

I also downloaded ROM from MIUI in Pie version (released week ago or so) and it also not working, same issue. I even had downloaded some update on first pie version. Now its very strange - when i had first Pie (before flashing 8.1) i have downloaded update - to seek for updates i need to use mobile data - thanks for my location only 2G is working, so its slow as hell, when update was found - i downloaded it with wi-fi.

With Youtube its also strange - i can make it working by turning ON wi-fi, launching app, turning wi-fi OFF, and ON and voila. Sometimes it works. I started also using "Secure VPN" app to make Youtube loading - it works, but not in way i wanted to - i need YT working for chromecast - with VPN i cannot connect to chromecast.

Finally Gmail - it sometimes - very rare working on wi-fi, but very soon after i think it fixed itself it again stop to working.

For flashing i tried used mi flash tool, and script commands included in image folder

You can probably try that : https://forum.xda-developers.com/showpost.php?p=78496783&postcount=40

Edit : this kind of stuff is a bit sensitive, keep in mind you can brick your phone, I don't know if it works I haven't tried myself, this is just a suggestion that looks similar to your problem (Sim swap, and it makes sense to me that the modem.img is also managing the wifi board (but really not sure about that).
BTW, I would do that with the Oreo ROM since I think the message is about Oreo. Then you can upgrade to pie again and see if you still have problems.

In my case, enforcing ipv4 in the router / access point settings has repaired WiFi.
I had issue with twitter, twitch, sometimes YouTube. I Could not access some websites.

I have no ipv6, i have tested this on 2 routers, now i'm checking 9.6.4.0 rom as i heard it have proper modem.img.

#kidoucorp - i'll try this also. I have tried updating to pie 3 times - i havent writed about this

So currently i'm out of options. Tried solution from your link, but it doesnt work

Wifi have worked like a charm after flashing 9.6.4.0 but my sim card wasnt working, system was saying its sim 2, so i wiped it for sure, now wifi is not working again, even after second flash with solution from the link. I wasnt able to login into google accounts, so i tried these steps from google help :
"
Hi there,
Go to settings>storage>cached data>clear cached data,
Go to settings> WiFi/ WLAN> name WiFi> forget> re enter password and connect WiFi,
Go to settings >security> screen Lock >add screen Lock,
Go to settings> Date & Time>select automatic time and date,
Go to settings >power manager >disable power saving mode,
Go to settings> storage> Apps>all>3 Dot menu>Reset app preferences> reset Apps,
Go to settings>storage> Apps>application manager> Download manager >clear data,
Go to settings>storage> Apps>application manager> Google play store >Force stop> clear data ,
Go to settings>storage> Apps>application manager> Google play services> manage space >clear data,
Go to settings>storage> Apps>application manager> Google services frame works> clear data ( below Android 6.o)
Restart device,
Go to settings >account >add account> select Google,
Add account.
Still problem persist,
Try after few hours.
"
And now i have signed into google, but google play store is plain white page. It wont download any updates as wifi is not working, and on LTE/3G/2G i cannot seek for any updates (default play store setting to download only on wifi). Android one is trap, never gonna buy device with this. Looks like i'm gonna try to sell this phone, but i dont know whos gonna buy it.

Any more ideas?

So i make it workable, but i cant login into damm google serwers. I hate everything that startd with G and have 2 oo inside.
What i have done :
- Downloaded 9.6.4.0 Fastbot image from here : https://forum.xda-developers.com/mi-a2-lite/how-to/ota-v9-6-4-0-odlmiff-t3823913
- unlocked bootloader again
- Flashed image without any changes via miflash
- On first config i choosed to not connect with mobile data or wifi, just skipped it.
- I configured phone once i saw desktop;
- turned off localisation, BT, switched to 2G, configured APN's,
- Configured gBoard, disabled Find my device, disabled FMD from administrators of device, disabled smartlock, and configured google settings so it cannot collect so much my data
- configured sounds, AND WIFI.
- Once i had wifi connected i went straight into SYSTEM UPDATES.
- I saw IT IS DOWNLOADING UPDATE FROM NOVEMBER without any notification. Pissed off about it, i went to developer settings and turned off auto updates.
- Went back to System updates and it was freezed on searching bar and nothing more, so i enabled autoupdates back, i get error it could not update, and in second try it updated.
- YT is working but i cant sign in to google serwers, "try again later".

So now i think i get what is hapening here. Android Pie, Google new owner, everyone have problems "with wifi" - that all BS.
Nobody have problems with Wi-Fi - wi fi is working well, in chrome, or any web browser its working, so DEVICES ARE FINE. Its Google serwers, google apps (using THEIR SERWERS) not working. So i guess new owner have no control ower everything and serwers have half of its speed, so lot of users sometimes have working gapps, sometimes not. If it could be only apps i at least could login into damm google account. What is not fitting into my idea is why PC versions are working OK - mobile devices are using different serwers?

PS : If anyone have Pie and having issues with wifi - try to logut from google account. All should start to works.

PS 2 : i logged into google store via secure VPN - again wifi is not working without VPN.

Phone is useless. LTE and 3G are working 1/5 its speed, its better to use 2G, Wi-Fi is not working on Google Apps. System updates are not working (infinite searching). Only thing that works are browser, messenger, SMS, calls, Deezer.

I dont get how people can not have this issue at all, what its dependent? I tried creating new google account - phone will not login into it. "Problems connecting to google serwers, try again later". Its most sh***y ROM ever created. Never had so much troubles on any custom rom on any phone. Thank you Google, f u G.

Have you tried Settings - System - Reset Options, then reset the WiFi from there?

Did you update the apps not working to the newest version? Otherwise if you have an unlocked bootloader (which i guess if u used the fastboot flash scripts) you could try to flash opengapps with twrp. Or you could get a logcat on a fresh installation and see if there is really everything ok with the rom.

have you tried joneplustool, you need root, but i did was toggle wifi bonding and my wifi started working fine, only had to do it once, but i suggest to flash magisk and use qualcom wifi bonding module.

Off course i tried, i even wiped fully phone severall times

All apps are updated, Google Plays Store is normally working, device is certified and udpates are normally working (for apps). Only problem was loggin into google account but after 7th or 8th try it worked. I dont have custom TWRP and have locked bootloader (scripts are doing it manually after finishing the flash). I dont try with TWRP and custom ROM's as i'm not familiar with it on this device (I have installed multiple mods - roms, recovery's. modems, etc on Redmi Note 4, but it was much easier). I'm also not familiar with logcat and its script language.

Well, at my work WIFI is working fine (for while), i have straight connection in work. In home, "friend" is sending me a signal (but its very hard to ask him for help) and i'm receiving it via wi-fi in my home. What he told me, i dont have ipv6 (he's not also). I tried 2 routers in my home - 5Ghz and 2.4Ghz - both same issue. In work i have 5Ghz, but 5 is not fitting to my home - i got low signal in the bottom of the house while router is on upper floor, lot of metal tubing, etc. its old building style home and it have some cons and props.

 

[vlad_8011]

Well, friend have changed something about DNS, system updater, youtube started working, he said there was some problems with 8.8.8.8 on my phone. after 15 minutes system updater again searching for updates infinite time, in 2G it works flash fast. Youtube still works, but who know how long... Any ideas?

BTW xda page also wont load on wifi....
