I do volunteer work for a crisis intervention center and we currently have a single FIOS line that goes into the FIOS router and then is distributed through a switch to the staff workstations. Management wants me to create a completely isolated wireless network for the shelter residents without having to bring in another high speed line, but it is important that there be no way the residents' can get into the other workstations or server that are currently installed not only because they contain confidential information but also because of the danger of virus infection. The primary use of the residents' computers will be to create resumes, search the internet for housing and jobs, etc. Would it be workable to bring the FIOS line from the FIOS router to a switch and then bring two lines out of the switch--one to a wireless router for the residents and the other for the business of the center? If so, would there be any way for the residents to breach the connection?
