I have an office with a wireless router in one corner of a fairly large house. Internet access is DSL. My computer connects directly to the router with an ethernet cable and does not run on a wireless signal. I have a Cat 5e cable that runs from that router to the opposite corner of the house where my wife's office is. Her computer connects directly to the ethernet cable for internet access (as mine does). There is no wireless reception on her side of the house, mainly because there are about 5 walls and 75 feet between the two offices. The wireless signal only reaches about halfway there. She will be getting a Smartphone soon that she would like to use with a wireless signal for internet access on the phone. What would be the best way to get a wireless signal in her office?
