Plugging in two Ethernet cables into your computer can lead to various outcomes based on your network configuration and hardware capabilities. Possibilities include enhanced performance through network bonding or link aggregation, automatic failover for redundancy, unintended consequences like network loops when bridging networks, manual configuration options, network confusion or inactivity in consumer setups, and the risk of IP address conflicts. In standard home or office environments, without specific configurations, using two Ethernet cables simultaneously may not improve performance and could potentially cause network issues. To optimize multiple connections, specific configurations and support from both hardware and network infrastructure are usually necessary.
