Will you need a wireless router for Wi-Fi connection even if you have a wi-fi usb connector?
Most wireless connections also require the use of a WiFi router
when using a USB Connector for a second desktop if the Internet
connection is hard wired to a desktop computer. If the main
Internet connection is a WiFi antenna on the building, then a
wireless router is usually not necessary, but the USB Connector is
necessary for a desktop computer.
