What is Wireless Router?

A wireless router is a device that performs the functions of a router and also includes the functions of a wireless access point.

Router + AP

A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.
Router
External networks must be carefully considered as part of the overall security strategy of the local network. A router may include a firewall, VPN handling, and other security functions, or they may be handled by separate devices.

Installation

One simple way

• Ventory
  • Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files.
  • With ventoy, you don’t need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly.
  • You can copy many files at a time and ventoy will give you a boot menu to select them (screenshot).
