Try changing the wireless channel. I remember having the same problem. Every time the connection dropped, my dad or sister had to come into my room to reset the router. I fixed it by changing the channel in router configurations.
I think routers normally default to channel 6, you want to change it to channel 1 or 11 to avoid interference with your neighbor's wireless routers.
