Wifi 2.4ghz

I'm facing a problem here regarding Wifi 2.4ghz, is disconnecting and connecting.

Already Wifi 5ghz works normal, no problems.

What may be going on?

Tenda Router AC11.

Mi 11 20.1.9

Problem solved, Wireless Bandwidth was at 40Mhz, I left at 20Mhz and so far nothing to drop the Wifi.
