TRENDnet 56K USB 2.0 Phone, Internet, and Fax Modem TFM-561U (White)

small and easy to install, but u will need access to a cd/dvd drive. don't know if u can download the drivers from the internet, and that may be an option, but check if you do not have the cd/dvd drive. worked just fine for dial up.

For a computer in a remote area with no access to high-speed Internet, a good modem is essential. This USB modem could not have been simpler to install and works well. Its portability from one device to another is an extraordinarily strong benefit.
