I have an early 2008 black model MacBook (2GB, 667 MHz DDR2 SDRAM, 2.4 GHz Intel Core 2 Duo processor). I want to make my internet connection through wi-fi faster because it significantly slows down when someone I share a connection with uses her MacBook Pro simultaneously. Would getting more RAM make my internet connection faster? If not, what can I do to improve the speed? TIA!
