I've posted a similar topic befoe a while ago, but as Im getting my iMac when Leopard is coming out, which is soon, I thought I'd make sure everything will work. Currently there is one PC (family computer) and one Macbook in my home (sister's). My parents PC use a NETGEAR MA111 802.11b adapter which sends a signal to our modem which is about 2 metres away. This is wireless, however as the adapter we use doesn't work on my sister's Macbook (not Mac compatible) she has an Ethernet port running about 3-4 meters to her Macbook (lol). I'm interested in buying the Airport Extreme Base Station, as I'm pretty sure this will allow my sister to have wireless internet, and the same with the iMac I'm purchasing. If this does work though, will my parent's home PC be able to use the router? They have the NETGEAR MA111 802.11b Adapter on their computer, so will that allow them access? Thanks for all the help, and its much appreciated, Mikey.
