MacBook Pro 1,1 Wireless Connection Problems

okay, so i'm having some wireless issues with my 06 macbook pro. the wireless connection is pretty spotty. i'm not sure what the deal is. the router i have is Linksys Wireless-N Broadband Router WRT160N Wireless router. i'm living in a back house which is ever close to the main house. i have a pc, ps, and a wii along with my macbook pro. all except my macbook pro seems to get good connection from the wireless router.

is there something that i can do to boost my wireless connection for my macbook pro?

Place the router at a higher altitude than it is now

i'll give that a shot when i get home from work today
