The prime objective of this study is to validate the extended technology acceptance model (ETAM) by incorporating two intrinsic motivation attributes, namely, computer self-efficacy and satisfaction into the original TAM to compare its viability testing on their satisfaction of the wireless internet service at a university. Besides, it evaluates gender invariant of the causal structure of this extended TAM. A total of 285 students from five major faculties (Education, Human Sciences, Engineering, ICT and Economics) were taken as respondents. The questionnaire’s reliability and validity were established through a RASCH analysis. The results as analyzed by Structural Equation Modelling (SEM) indicate that students’ perceived ease of use had a statistically significant effect on their satisfaction. The study revealed that gender did not exert any influence as a moderating variable towards students’ satisfaction in using Wireless Internet. The findings contributed to a better understanding of the TAM and technology satisfaction among students.
