CAN I COMBINE WIFI SIGNALS AROUND ME FOR A FAT PIPE? USING SEVERAL WIFI ADAPTERS?

Like I use makyamas free-wifi finder, and I have several wireless cards--usb: 2 from sprint, 1 from verizon, one in notebook and one external just for wifi. I want to combine them for one fat pipe and then send them thourgh my apple airport extreme for my self and neighbors; but I want to protect my internal data and such.

Why ? Your pipe won't be any fatter than that wire out of your place. Steve
