I guess your particular hardware will have to be used that way.
Back to #1: "What are minimum requirements for success"?
Do you mean, how strong a signal must you receive? If you're in a rural area with few wifi signals, you might have acceptable reception over a surprisingly long distance. However, in city areas with dozens or even hundreds of wifi routers in range, you might not be able to connect to even a fairly strong signal.
Trial and error, trial and error.
Good luck!
