Files gives read only access to SMB drive

To enable read-write access to a USB drive connected to your router via SMB on your iPhone running iOS 18, you can follow these steps:

1. Check Router Settings:
   1. Access your router's administration interface via a web browser.
   2. Navigate to the USB or storage settings where the SMB share is configured.
   3. Ensure that the share permissions are set to allow read and write access for the user account you are using to connect.
2. Verify SMB Share Permissions:
   1. Ensure the SMB share on your router is not set to read-only.
   2. Check the user permissions and make sure they include both read and write access.
3. Update Router Firmware:
   1. Ensure your router's firmware is up to date. Sometimes firmware updates can fix compatibility issues with SMB sharing.
4. Connect with Correct Credentials:
   1. Make sure you are using the correct username and password for the SMB share that has read-write permissions.
5. iOS Device Settings:
   1. Go to Settings > Files on your iOS device.
   2. Under Browse > Connect to Server, enter the SMB address of your router.
   3. Enter the correct credentials when prompted and ensure you are logging in with an account that has read-write permissions.
6. Check File System Compatibility: While FAT32 is generally supported, ensure the USB drive is not corrupted and is properly recognized by the router.
