Wireless connections are highly convenient in many situations. But should you require high data transfer rates, then cable connections are more secure than wireless ones, i.e. they offer a lower risk if security measures available via WLAN are not or cannot be fully exploited. For example, an Ethernet interface is the best way to transfer files between devices with maximum transfer rate and security.
