A modem, short for "modulator-demodulator", is a device that allows computers and other devices to connect to the internet or other networks by converting digital signals into analog signals that can be transmitted over telephone lines, cable lines, or other types of communication channels.
Why is it anytime I try inserting my HSPA USB modem into my laptop USB port and I click on connect it shows authenticating which is normal and all of a sudden it disconnects I even changed the USB port
