I did not ask what the people who should use the WIFI are trying to connect with. What are you using so that we could guess where to set the range?
And besides that - "1 foot" is a bit low to have people "who sit at the table" within range. What kind of table are you talking about? A rectangular table at home (surrounded by your own walls that dampen any signal)? Or a square table in the middle of a public diner?
