An S24 Ultra that drops Wi-Fi often started after an update. Owners in Samsung's forums said One UI 7 dropped them from Wi-Fi 7 to Wi-Fi 6 and, for some, caused drops of 10 to 20 seconds several times a day, and a later thread dates new disconnections to the April 2026 update. The S24 Ultra supports Wi-Fi 7, so a router that puts 2.4, 5 and 6 GHz under one name gives the phone room to choose badly. Give each band its own name, reconnect to the 6 GHz one and see whether the drops stop.
Differential
Likely causes of “Samsung Galaxy S24 family will not connect to Wi-Fi or keeps disconnecting”, and how to tell them apart
- 1
One UI 7 negotiating a lower Wi-Fi standard
What separates it The Wi-Fi 7 badge is gone and speeds fell, or the phone reconnects every few minutes
How to confirm An owner's fix in the thread was splitting 2.4, 5 and 6 GHz onto separate names so the phone stayed on Wi-Fi 7 at 6 GHz
- 2
The April 2026 update
What separates it Drops began in April or after
How to confirm Threads describe random drops after that update; install any newer patch
- 3
A saved network gone stale
What separates it One network drops and others are fine
How to confirm Forget it and join again; owners reported stable results
- 4
A weak 6 GHz signal
What separates it Drops happen in the next room
How to confirm 6 GHz carries less far through walls; the phone should fall back to 5 GHz under its own name
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether the drop began after One UI 7 or the April 2026 update
- Whether the router uses one name or separate names for each band
- How long a drop lasts, in seconds
- Whether the phone shows Wi-Fi 7, 6 or 5

What is true of this model and not of its siblings
- Wi-Fi
- GSMArena lists Wi-Fi 7 and Bluetooth 5.3 for the S24 Ultra.

Common questions
Did One UI 7 break Wi-Fi 7 on the S24 Ultra?+

A US community thread dates new S24 Wi-Fi disconnections to that update; Samsung had not published a fix when it was posted.
