I don't have wireless but am considering it. What is the range? Would it be illegal or possible to share a connection with my neighbor?

Get only a 108Mpbs, not a 54 anything and use Netgear products for range.
Place your wireless router closest to your neighbor at a window preferably.

A couple of average houses should be able to share and with laptops you should be able to use the net on both properties in the yard up to the street in most cases.

Sharing isn't loved by the company providing the service.

One would have to host and pay the bill and the other place would only need the 108Mpbs receiving devices.
