Hi @Daxsh
Please do check your networks mast status via any relevant online mast checker portal they have just to ensure the issue isn't at their end, unless this us happening everywhere !
If everywhere then as a process of elimination try your sim card in another another phone to help rule out a sim card issue please.
In your phone's settings you can reset network settings i.e it refreshes them.
Settings > General Management > Reset > Reset Network Connections.
You could also try an app called Samsung Band Selection.
This is found in the Playstore and allows a person to try out other bands to see if another option works better.
In regards to Wi-Fi.
Is this Home Broadband Wi-Fi ?
If so in your Home Router try choosing another channel with may not be as busy as the one your currently using.
And if your router allows this split the frequencies in your Router to 2.4ghz and 5ghz as some phone's prefer one over the other.
What's the phone like if you connect to outside Wi-Fi such as a Coffee Shop etc ?
Try...
Settings > Location >Google Location Accuracy > Toggle off.
Daily Driver > Samsung Galaxy s²⁵ Ultra 512Gb ~ Titanium Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
