Hi everyone! I have a problem with my Poco x3 Pro and I wanted to see if the same thing happened to someone, or ask for advice to find out where the problem comes from.
I bought a Poco x3 Pro 6 / 128gb 3 months ago, and last month, the wifi began to lose the internet signal since it is still connected to the wifi network but it is as if the signal was cut off, and it is enough to turn off and quickly turn the wifi back on on the phone to regain the signal.
It seems like something that can be quickly corrected, but when I'm playing online, it is quite annoying since suddenly without apparent cause, the Internet is cut off (with Wi-Fi and the network connected).
As additional data, it came with MIUI version 12.0.6 and although I updated to 12.5.2 (I also did a factory reset) the problem continued to occur.
Has anyone happened to you or advise me how can I find out the source of the problem? Since it could be my wifi (I really do not think so, I have a Redmi Note 9 Pro, Redmi Note 8 and Redmi Note 6 Pro and this does not happen, the signal is quite stable) or the same phone.
Thank you and sorry for my english haha

Firstly, 'forget' the WiFi connection on the phone and then turn off your router for a couple of minutes. Boot the router back up and once it's settled down re-connect your phone.

You don't say how often or quickly this occurs but if it does still happen then can you test elsewhere? Either a public WiFi connection or a friends or family members home maybe?

I get similar problem, usually after a night. Phone shows WiFi active, but no Internet connection and no ping to any local device. Other phones have no problems with the same WiFi network. It is enough to turn off WiFi on phone for a moment to get it working again.
My POCO is V12.5.1.0.RJUEUXM.

Yes for me. I didn't use this phone much, while waiting for bootloader unlock. It updated itself to MIUI V12.5.1.0.RJUEUXM at first boot and since then I observed WiFi loosing connection after nearly each night. But I noticed no breaks, while actively using the phone.

It is strange, in my case it will be necessary to test it with another WiFi..

PD: I update, it keeps happening to me, I will only use 4G to play games ..

I switched to ArrowOS and noticed one instance of WiFi failure. Then I disabled random MAC on phone and it seems to work OK now, but is to early to draw any conclusion. I don't remember if random MAC was active in MIUI.

While rare, problem still exist. Effect is that WiFi connection is broken an system cant find AP. But WiFiAnalyzer work OK and shows available AP. Turning WiFi off and on restores connection.
