    villapx , May 6, 2021 :
    Does it have to do with the new "Smart Wi-Fi Connection" settings? I noticed that what's been happening to me specifically is that my phone is bouncing back and forth between my 2.4GHz and 5GHz networks, as others have alluded to (i.e. the workaround of "Forgetting" one of them).

    I noticed that there's a new settings section, I think with this Android 11 update, called "Smart Wi-Fi Connection". It's under Settings > Wi-Fi & Network > Wi-Fi > Wi-Fi preferences. Under this section, the setting Intelligently select the best Wi-Fi was enabled. The description of this setting is, "Intelligently select and connect to the best Wi-Fi by detecting and analyzing the connectivity of Wi-Fi networks".

    I've just turned this setting off, and although it's only been a couple minutes, my phone hasn't been bouncing back and forth between my two Wi-Fi SSIDs anymore. I'm curious for others to try changing this setting and seeing if it stops the behavior.

    Why should you re-enable something that is causing a problem?

    I am interested in the problem and its possible cause. This requires some experimentation :)

    This is a bug in the OS.

    Some people have said it doesn't help unless they 'forget' the 5 GHz band, even though the router broadcasts it with a separate SSID.

    But yeah, nothing wrong with experimenting.

    There is no issue when u have only 1 of 2.4 or 5ghz connected.
    It happens when u have same network with on both Bands.

    Since the update to Oxygen OS 11, my device disconnects from WiFi automatically in every 10-15 mins and then reconnects after 10- 20 seconds. My device is OnePlus7t and this is getting very annoying.

    Well, I have only one band active (2.4 GHz) and I do have this issue.

    I've recently done the android 11 update, and I've noticed that my wifi keeps disconnecting every few minutes and then reconnecting despite there being a stable connection with no issues

    A lot of others got it working again by disabling intelligently select the best wifi and if you have both 2, 4 and 5 ghz bands connected, deleting one of them
