Wireless technology allows you to access high-speed Internet wirelessly from anywhere within range of your wireless router whether it’s your office, your favorite couch or under a shade tree on your deck. You can also share high speed Internet access among multiple computers, share files and even print documents without the hassle and unsightly tangle of wires.
If you want to access the Internet wirelessly at home, you will need the following three items:
- Broadband Internet access like DSL or cable (not dial-up)
- Wireless router to connect to your cable or DSL modem
- Wireless card for your computer such as an Intel PRO/Wireless or Dell Wireless internal card or external product such as a Wi-Fi ExpresscardTM or USB 2.0 Wi-Fi adapter.
