Mi 9T can't connect to 5GHz wifi?? - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hi guys ,
I have one issue with my Mi 9T for quite some time that I couldn't fix , if anyone has any idea if you can share I'd be appreciated.
I have a Xiaomi Mi Wifi mini router and it supports wifi 5GHz. I have Mi notebook air 13 , MiPad 4 , my wife's Poco X3 all of them connected to this Wifi and can see 5GHz without any issues. Even my wife's old phone Samsung Galaxy J7 prime from 2016 can see 5GHz. But somehow my Mi 9T can connect to it only when I take the phone to airplane mode. If I close airplane mode and disable wifi and open again, 5GHz disappears. I'm using Xiaomi.eu 12.2 Android 10 version and I also tried Android 11 version of xiaomi.eu , global version also tried but all of them have same issue. Any ideas how to fix it?

[Q]Problem with Bluetooth connection between Xiaomi Mi Band and Lenovo P780.

Hello,
I bought Mi Band to my Lenovo P780 and I have connection problem. I have paired both devices and everything works well but 10-20 times a day connection is lost. And after I open Mi Fit, app try to connect with phone and do a sync but it can't. Only after turning Bluetooth off/on app can connect to phone and do syncing. This is very annoying. Always after night the connection between Mi Band and phone is broken. What can I do about this problem? I need have a real-time notifications on Mi Band so I need have stable connection between phone and band all the time.
I have Lenovo P780 on 4.4.3 and Xiaomi Mi Band on firmware 1.0.9.0 + Tweaked Mi Fit with notify 1.2.922.

wifi slow with bluetooh on

When I connect the bluetooth in my device the wifi is extremely slow, it does not have to be connected to any device, just turning on the bluetoothh the wifi loses speed drastically. I've used custom rom, kernel, hard reset and nothing solved ...
Help, help, because I can not use my beep amazfit.
Thanks to this post I realized the reason why my WiFi connection in my MI A1 was utterly slow.
Did you manage to fix it? How?
Same here.
Very weird indeed .... same wifi speed issue here. (still with original Android Rom updates , no customs)
BT off FULL speed
BT on very slooooooow .
Is this only Mi A1 related ???

What I read is that Bluetooth and wifi uses the same bandwidth so we need to change our router to 5 GHz to avoid this problem.
Indeed.
But the question is still why XiaoMi have changed that with the Android Pie update?
Btw, have checked my Fritzbox 7360 router and no, no option for 5Ghz band.

Xiaomi MI A1 as a wifi repeater

Goodmorning
I have both a Xiaomi MI A2 lite (cr droid installed) and a Xiaomi MI A1 (evolution X installaed).
I would like to use them as wifi repeater.
I tried to switch on both the wifi and the hotspot toggle but only one of them can work, they can't work togheter.
Then I tried to select Enable Wi-Fi Coverage Extend Feature in the "developer option" and do again the point above.
Nothing of that work.
I don't want to use apps like "Wi-Fi Repeater" because I need to install an app also in the devices connected to the repeater.
Any ideas?
Thanks.
