Hi Etonam and welcome to Geeks to Go,
Most home wireless access Points (often incorporated into a router) have a range in unobstructed air space of around 30 metres (or about 100ft.) The wi fi signal is attenuated by intervening walls, obstructions, machinery etc so may be less than that in some environments. It is of course subject to interference from other transmissions operating on the same or similar frequencies.
if you want the wi fi to extend "far into your neighbourhood" then the options are basically to buy commercial equipment (and it's not inexpensive) or build your own if you have or can obtain sufficient expertise to design and built the infrastructure yourself or otherwise purchase the component parts and assemble them yourself.
Long range antennae are available and are often used for neighbourhood networks, marinas, camp sites, business locations and the like. However before creating a long range network its important to decide who will have access to it, under what conditions and It would be wise to enlist the help of your Internet Service Provider as they may have proscriptions on the use of shared network facilities for commercial or even private use and may require you to enter into a business arrangement before allowing it.
