I've had the same netgear router for a few years now and it has worked fine, recently the internet has been running slow on our (roommates) computers. I have a new macbook (titanium) and they have the older (previous model) white ones. I called (ISP is cox communication) and upgraded our internet speed assuming it would become faster and it has but not much, think if we got an airport express with Simultaneous dual-band that it will speed things up since the connection is faster and a newer modem would be in the house?? or should it really not make a difference?? and last question how can I tell which technology the computers are using for the connection? apples website says the new computers operate on 802.11n technology, I'm assuming mine does too, how can I tell what their (roommates) computers use? Im assuming its the g technology THANK YOU in advance.
