Overview of QMO-l21 and QMO-234 wireless routers
In the telecommunications equipment market, wireless routers are widely used, which act as access points to ensure the interaction of devices with each other in private computer networks, as well as with the outside world through the global Internet.
One of the main functions of wireless routers is to provide shared access to an Internet connection to several network devices, where an important feature is the observance of the security of data packet transmission over the network. An Internet service provider from its DHCP server assigns an IP address, which the router translates into a set of local IP addresses.
