Router accessories are additional components that enhance the functionality and performance of a router. Common accessories include Wi-Fi extenders, which boost the signal range, and network switches, which allow multiple devices to connect to a single network. These tools help improve connectivity and ensure a stable internet experience. Other useful router accessories include cables, such as Ethernet cables for wired connections, and mounting brackets for secure installation. Additionally, powerline adapters can extend the network using existing electrical wiring, making it easier to connect devices in different rooms. These accessories contribute to a more efficient and reliable home or office network.
