The level of Internet usage has rapidly grown in Thailand. Millions of the Thai population are currently connected to the Internet because of its potential to become the backbone of the information economy and communication. This study explores the purposes of the internet usage of Hmong farmers in a rural area of Chiang Mai province, Thailand. The mixed methods research was used to individually interview 73 informants, which was determined statistically by the Cochran formula at the significant level of 0.05. The findings indicate that they used the internet, with the help of Line and Facebook, to serve social purposes as a priority. It provided information and created social bonds to maintain their agriculture and livelihood. However, constraints associated with Internet usage were found. Interesting information was not user-friendly as it was mostly presented in foreign languages. The lack of training to exploit the Internet’s more utilities and the poor internet networks were also their main challenges. To boost internet usage, high speed internet services and related infrastructure should be the focus for the government. This must be done together with training delivered by local officers.
