ABSTRACT: The development of computer technology is increasing rapidly, as seen in the 80s era computer networks is still a puzzle to be answered by academic circles, and in 1988 began to use computer networks at universities, companies, now entering the era of this millennium, especially the world wide internet has become an everyday reality of millions of people on this earth. In addition, hardware and network software has really changed, at the  beginning  of  its  development  almost  the  entire  network  constructed  from  coaxial cable, now many of them have been constructed of the optical fiber (optical fiber) or even without both cable communications (wireless).
With  the  development  of  computer  technology  and  communication  of  a  single computer model that serves all computing tasks an organization has now been replaced by a set of computers that would separate but interrelated in performing their duties, such systems  are  called  computer  network. Internet  cafés  or  better  known  as  cafenet, recognized  as  having  its  own  color  in  the  development  of  information  technology  and communications  in  Indonesia.  With  nearly  more  than  two  thousand  average  cafe  was founded  in  the  midst  of  economic  crisis  in  recent  years,  its  influence  in  the  world  of telecommunications business and the business world that Indonesia has been significant.

In  recent  years  many  stall  telecommunications (telephone) that transforms services into Internet cafe, then to meet that need, Telkom asa telecommunications service provider providing  services to the initiative by adding data access  using  ADSL  modems  that  have  been  able  to  connect  with  the  old  network (telephone network).
