I have a 2002 EMAC desktop and recently we have moved to a different home where the internet connection setup is more than I can figure out. Upstairs, 3 walls, and 200 ft away is the main wireless modem (Qwest 54 Actiontec). I want to know what other hardware (whether Apple product or not) would make my wireless connection to my desktop strong and reliable. After searching and researching with Best Buy and Apple employees, I have yet to find the correct combination of wireless card, adapters or any other items needed. I currently have a d-link wireless adapter (802.11) and an Airport Express. I know I need a wireless card of some kind but which? And do I need to worry more about increasing the range of the adapter before trying to get the more expensive wireless card? Any experience with this would be happily accepted.
