What have you tried thus far @Masser ?
Does this happen everywhere you go ?
Is this happening on bith a Wi-Fi and mobile data connection ?
Daily Driver > Samsung Galaxy s²² Ultra 256Gb in Phantom Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help.
@Masser: To troubleshoot the issue, please try pressing the Volume Down and Power buttons together for around 10 seconds until your Z Fold3 restarts. Don't worry, this won't affect your personal data or settings. I also recommend unplugging your router at the wall for 30 seconds, then plugging it back in and waiting for the reset process to complete. Following these steps, head back to Settings > Connections > Wi-Fi > On, then select your router (unless you're set up to auto-reconnect).
If the issue persists, can you confirm if you're still able to connect other devices in the household to the same router without issue? Also, have you tried connecting to another Wi-Fi router (a friend or family members) to see if the issue persists?
