My mother in law also had this problem with her note 20 ultra. Turns out after the last update turn on WiFi automatically was no longer on. Double check in connections - press the 3 dots in top corner, go to advanced. It will be in there.

Hi, thanks. It is on, the problem I got is it keeps turning off automatically.

@91antoniolopez: Can you try heading to Settings > Connections > Wi-Fi > Tap the 3 dots in the top right > Wi-Fi Control History, and check to see if any apps have turned your Wi-Fi off. If you find anything that corresponds with your issue, and it is a third party app, then you may wish to uninstall it to prevent future occurrences. 

Further to the above, please head to Settings > Connections > Data Usage > Mobile Data Only Apps, and either toggle this option off, or remove any apps that you use frequently while connected to Wi-Fi. Let me know how you get on.

Hi thanks, Andrew.
No luck, control history is only Bixby that I'm using as a fix.
And Mobile Data Only Apps is toggled off.

@91antoniolopez: Can you also try heading to Settings > Connections > Wi-Fi > 3 dot > Advanced > Switch To Mobile Data > Off > Wi-Fi Power Saving Mode > Off. If the connection continues to drop, try connecting to another Wi-Fi network, a friend or family members, to see if the issue persists, as this will help to determine if the problem lies with the phone or your current router.

How? How do you use Bixby to keep wifi on? How did Samsung mess this up sooooooo bad? Internal wifi controller faults on Galaxy phones?

Jan 2023 - just started having this issue yesterday.

Have tried ALL the recommended troubleshooting suggestions (except factory reset) and it's still happening.  Does anyone have a good solution?

Have:

• reset phone
• reset router
• gone through the wifi/advanced and switch everything off
• uninstalled the last app that did an update (only 2 apps updated in the last day)
• checked wifi control history - only two apps have access to switch wifi on/off 

argh!  can anyone please assist?

Mine just started doing the same thing today. i'll get it turned on for just a moment and then it shuts off instantly or wont turn wifi on at all

Here is what I have just discovered.  I had turned on in the advanced field of wifi that it would turn on and off automatically, when I first turned on this option I was not sure what it would do.  Now I see that this had caused me problems with my wifi being turned off and I just didn't see it or think about it.  I have copied the words for this option when you click on the 3 dots in the upper right hand corner of wifi.

Turn on Wi-Fi automatically when
you're in places you use it frequently
and turn it off elsewhere.
