Redmi Note 6 Pro WIFI issues - Xiaomi Redmi Note 6 Pro Questions & Answers

Hello, got a brand new Redmi Note 6 Pro and it doesn't matter how I connect to the internet via WIFI (DHCP or STATIC) the phone keep loosing the WIFI connection if I open two or more apps at the same time - multimedia apps that load images, or videos for example Youtube + Netflix. Or if WhatsApp runs in background and I open VLC the WIFI disconnects automatically. At this point I don't know what to think if is a hardware issue (bad RAM?) or a software / firmware issue, any ideas? Running the latest MIUI (10.0.4.0).
Update: I just realized that the WIFI stops working on my Redmi Note 6 Pro only when I have a Sony Bravia Smart TV on!! If I turn off the TV the phone works fine, no more disconnects. So what can I do apart turning off my tv? Obviously there's some sort of conflict with the Bravia Smart TV connecting to the same router (a 300M Wireless N Gigabit Router Model No. TL-WR1043ND).

This is really strange. I have the same router (running DD-WRT) and a Sony smart TV. And my Redmi Note 6 also loses WiFi... no solution found until now.

J7 Crown won't stay connected to screen mirroring

Troubles with finding where to edit my profile as well as locating my device. It says that I have a note 3 from AT&T;
I have a Samsung J7 Crown from Straight Talk.
The issue im having is that my device connects ("screen mirroring " / SmartView) to my TCL roku tv just fine, until after about ten minutes - give or take - then it disconnects without giving any notification on tv or phone as to why. Everything is updated as far as I am aware, even my tv.
I have tried different locations and distances. Issue persists.
Please help, thanks.
*side note: Since I only have internet on phone, could I connect my tv and phone to a wireless router and expect a more stable connection?

wireless display mi mix 3 after miui 11

hello, I followed your instructions ( Post of OEL
"But there is a solution.
Go to developer options and enable wireless display certification.
Than go to "connection and sharing"/"wireless display and enable wireless display.
Now you see some stuff. Go to "operating channel" And change from auto to 6 or 11.
Now connect your tv." )
And I so i managed to connect my mi mix 3 in wireless display to my samsung smart tv and now finally works.
Thank you for this.
However When I then restart or turn on the smartphone, I activate the wireless display, and I have to set operating channel 11 again, otherwise it won't work. Why is channel 11 not stored?
second problem. the home modem is dual band. Samsung smart TVs connect to both networks. But my mi mix 3, connects in wireless display only if the TV is connected to the 2.4 ghz wifi network. If I connect the TV to 5.0 Ghz, the phone does not detect any Samsung smart TV. Please can you help me. I would prefer to use 5.0 in wireless display. Thanks
My phone mi mix 3 have miui globall stabile 11.0.40

Redmi 9C connected to wifi but no Internet

I just bought this phone and I'm trying to use it in my network. I use Ubiquiti products (16-port switches and a bunch of AP access points). I connected the phone via wifi to my network and it has no problem for a while until it just doesn't have Internet connection. It stays connected with its IP address intact but for some reason it cannot seem to reach the Internet. The workaround is to simply turn off the wifi module and turn it back on. It's randomly happening and the workaround is very annoying.
I have a couple of other mobile devices (iPads, iPhones, Android phones, Windows laptops, etc.) and I never experienced the issue with these. I tried connecting the Redmi 9C to all my wifi networks:
Guest wifi with captive portal
Main wifi with RADIUS authentication
IoT wifi with regular WPA2 personal authentication
I tried resetting the wifi settings of the phone. I tried reinstalling the latest MIUI fw/sw.
and the result is the same, every time. At this point, I can safely consider that there has to be something wrong with the phone. I'm not sure if it's because of the MIUI 12 update because I updated the phone to the latest firmware as soon as I got it out of the box. Is this a known issue with this phone? I have another Xiaomi phone (Mi Mix 3) on the same network without any issues.
Any ideas?

Problem with Sonos Roam? Can't wake it up from sleepmode

Hi, everyone!
I bought a Sonos Roam. Normally, you should be able to get the Sonos Roam out of standby mode by opening the app. I can also do this on a laptop, on a Samsung smartphone - but I can't do it on the Xiaomi Poco F2 Pro. Bluetooth AND GPS must be switched on in parallel for it to work. Although only WLAN should be required for this (as on Laptop & Samsung Smartphone). Are there any settings that I don't know that cut the WLAN and are canceled when Bluetooth / GPS is activated ???
I tried every setting i could find and cant get it to work...
Many Thanks
