I want to connect a pc running windows xp and a (new) wifi enabled dell laptop running windows vista.
I know I need a wireless router (I have been told by AOL that I need a Netgear DG834G but do I also need a wireless usb adaptor or can my pc be connected to the netgear router using an ethernet cable?
Your PC can be connected to the router by ethernet, in fact it will probably need to be to set up the router. IMHO, I'd rather have my main PC cabled rather than wireless for a number of reasons.
P.S. I'm assuming your PC has a network card built in!
I'm not a computer expert, but I'm pretty certain that you don't need a wireless usb adaptor. Your laptop is wifi enabled and your PC can be connected to the router using an ethernet cable.
assuming the PC has an ethernet hole
and the laptop will probably have both.eth and wi-fi
you're already set - check first ... 'cause if you do need a usb wifi adapter ... you are best getting the same brand as the router
if you want to get the two talking ... you'll need to enable file sharing in Vista
read the book .... setup the router ... enable wireless security (wep is good enough unless you work for mi5) AND mac filtering
use the network setup wizard in xp and vista ... easy
