My brother has a three level townhouse in Bogota, Columbia. His lower floor has an older motorola modem and router (which came with the housethat can feed up to the second floor. However, the WiFi just won't reach up to the third floor where his patio and game room is. Too much concrete I would guess. Any suggestions on how to get that signal up to the third floor. Take into account that he nor his wife are that tech savy and the Columbia doesn't offer much in internet help or hardware. She runs a macbook and he a PC. Thanks.
