Extension 2

The 2 ISP providers that are used in my area are DIAL UP and WIFI.

DIAL UP
Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network (PSTN) to establish a dialed connection to an Internet service provider (ISP) via telephone lines. The user's computer or router uses an attached modem to encode and decode Internet Protocol packets and control information into and from analogue audio frequency signals, respectively.
The term was coined during the early days of computer telecommunications when modems were needed to connect terminals or computers running terminal emulator software to mainframes, minicomputers, online services and bulletin board systems via a telephone line.
WIFI
Wi-Fi is a wireless standard for connecting electronic devices. A Wi-Fi enabled device such as a personal computer, video game console, smartphone, and digital audio player can connect to the Internet when within range of a wireless network connected to the Internet. A single access point (or hotspot) has a range of about 20 meters indoors. Wi-Fi has a greater range outdoors and multiple overlapping access points can cover large areas.
"Wi-Fi" is a trademark of the Wi-Fi Alliance and the term was originally created as a simpler name for the "IEEE 802.11" standard. Wi-Fi is used by over 700 million people, there are over 4 million hotspots (places with Wi-Fi Internet connectivity) around the world, and about 800 million new Wi-Fi devices every year. Wi-Fi products that complete the Wi-Fi Alliance interoperability certification testing successfully can use the Wi-Fi CERTIFIED designation and trademark.
WHICH ONE?
In my opinion i would get WIFI because it is easier and cheaper and very convenient.
