Fold 4 WiFi Issues

[Sengoku]

My Fold 4 is terrible at keeping a wifi connection with my router and will often swap to mobile data. 

No issues with any other devices and my router so I was wondering if anyone else was having this issue and managed to find a fix?

How does you phone perform when connected to another source of Wi-Fi such as a coffee shop or other person's home broadband router @Sengoku  ?

Some troubleshooting tips are > You could try forgetting the network in your phone and set it back up and then see what happens.

And if your router allows it split the frequencies in the router to 2.4GHz and 5GHz and then again firget the network in your phone and then connect to one frequency and then the other to see if that helps.

Your phone has a diagnostic tool in the Samsung Members App under the GetHelp section which you can use.

If I can be of any further help then please don't hesitate. Take care.  😎

Thanks for responding. I think it's OK in other places and it seems to be a distance issue. The reason I'm asking is that my previous S20+ had no issues maintaining a stable connection from the same room.
Will try your suggestions and let you know if it improves. Thanks again.
