Routers are designed to connect multiple networks and direct packets to their intended destinations across network segments. This makes them essential for directing packets to networks outside of the LAN, such as the internet or other remote networks.

When print jobs remain stuck in the printer queue despite successful network communication (indicated by successful ping replies) and no issues with paper supply or toner levels, a common reason can be that the first job in the queue requires manual intervention, such as paper to be fed into a manual feed tray. Printers often pause the entire print queue if the first job requires a specific type of paper or manual insertion that hasn't been addressed, preventing subsequent jobs from processing.

When two devices on the same network are assigned the same IP address, it can lead to intermittent connectivity issues as the network switches between the two devices. This situation, known as an IP address conflict, can disrupt the normal operation of the network, leading to connectivity problems that appear sporadic or intermittent. Resolving duplicate IP addresses typically involves ensuring DHCP is correctly configured or manually setting unique static IP addresses for devices prone to conflicts.

When a user is unable to save pictures to a new SD card after replacing a damaged one, the first thing to check is whether the card is locked. Many SD cards have a physical switch on the side that can be toggled to a "locked" position, which prevents data from being written to the card. Ensuring the switch is in the "unlocked" position allows the device to save data to the SD card.
