Wireless modems can be installed internally or externally on your computer. Both laptops and computer desktops can be configured to use a wireless computer modem. When choosing a wireless modem, you should consider the following factors when making your decision: security level provided by the router, price, router communications protocol and support from your Internet Service provider for the modem.

Difficulty: Moderately Easy

Choose what modem communications protocol you will purchase based on published reviews and your needs for connectivity. The published reviews listed in the resources section of this article provide information on the modem protocols currently being sold.
