But here's how they fix that. They sprinkle WAPs or APs as needed to get the coverage. Someone new to this may think a "powerful" WAP is used but this is not true. Also the frequency is dictated by the 802.11x standard so we can't move it to get through materials better.
So here's the fix. Drill hole, put AP on other side of wall.
Does anyone know of routers that can send signals through a high density wall (brick, concrete, etc.) or a commercial (for hospitals,airports,city wide wifi,hotels, etc.) grade router.
Thanks in advance.
