I need to have my powerbook G4 connect to broadband wirelessly and a PC downstairs physically connected to the internet. I recently bought a Lynksus G broadband router (which I can very easily return) and have been going back and forth whether or not to get an airport base. My question is whether you think the Airport Base or Airport Extreme Base Station is better than the wireless router I just purchased. I need something that will be fast and secure (I am a grad student) and be dependable regarding signal strength so I can use it on the second and third floor of the house even though its connected on the first floor. Also I called the "24/7 helpline" and they refused to give me any advice on what I should do with regards on how to set up the wireless network on my Mac. Any help you could give me regarding the subject would be greatly appreciated.
