Small office/home office (SOHO) routers play a crucial role in the networking setup of millions of consumers. Serving as the primary gateway for SOHO networks, these routers handle a wide range of functions including managing domain name resolution, providing firewall protection, implementing dynamic addressing through protocols like DHCP, offering wireless connectivity, and of course, routing data packets between devices on the network and the internet. They are essentially the backbone of the network infrastructure for small offices and home offices, enabling seamless communication and data transfer while also ensuring security and efficient data routing.
