the apartment complex where I live offers free internet from the front office. what that means is the units next to the office get free wireless access and those who are out of range are out of luck. our unit is about 800 yards from the main office where the internet is available. I've heard of ways to get the signal repeated or something to that effect or I can point a repeater at the office which will boost the signal for use in my apartment. Any body know much about this?

Thanks.
