Final answer:
Most new wireless routers come with a preconfigured firewall and encryption settings, namely WPA or WPA2, to protect the network from unauthorized access and ensure data security.
Step-by-step explanation:
The two preconfigured settings that affect security and are commonly found on most new wireless routers are firewall and encryption. A Firewall acts as a barrier between your internal network and untrusted external networks such as the internet. It filters incoming and outgoing traffic based on a set of rules to protect the network from unauthorized access and cyberattacks. Encryption, on the other hand, secures the data transmitted over the wireless network. Most routers come with Wi-Fi Protected Access (WPA or WPA2), which is a security protocol that encrypts the data on your network to prevent eavesdropping and ensures that only authorized users can access it.
