Wifi issues in a53

[Traveller_KL]

Does anyone else experience issues in wifi with a53. 

It apparently goes into some sort of sleep mode and just doesn't receive any notifications when on WiFi. This happens when I leave the phone for sometime in idle mode. So it goes into some sleep mode and then when I reselect wifi or even restart phone it gets connected. All the time I see wifi signal but it doesn't receive any notifications 

All my other devices are working fine on the wifi.

Setting in wifi also checked but doesn't work.

I also use Samsung a53 5g phone, but I don't use any mode. Normally I use this phone.

Ok..so sleep mode doesn't refer to the sleep mode that u can set manually..its like the device itself get into inactive state..

I am not sure if this is due to samsung VPN which I see is active on the phone causing it to go into data saving mode on WiFi...I have no idea why is it happening
