The problem is in the phone. Can you help?

Question

WiFi

The phone (Xiaomi Redmi Note 8T) takes all the Wi-Fi and the maximum speed is two or even three times less, and the ping is also due to this phone from others? I reflash, the same thing starts.

Answer 1

If your router - you need to ask him to collect statistics on traffic from this phone. First you need to find out what exactly is happening:

1. the phone sends correct requests to the outside (then we look - where exactly; and what clogs the channel - requests or answers);
   
2. the phone works crookedly with WiFi and just litters the air.
   

Answer 2

The WIFI module may not work correctly in the phone (hardware or software problem). If the phone uses slow speeds (this can be checked on the client in the connection properties) to connect to WIFI, then all WIFI clients of this router will suffer. because WIFI serves clients one by one and this client takes more time than others. In WIFI terminology, this is called a "slow client", there is also a router with protection against slow clients. You can try tweaking your router settings (change channel, disable TKIP, change channel width 20/40)
