Just wondered if a broadband modem, an access point and a noteboo
with a wireless network card is enough (hardware wise) to get onlin
wirelessly

If yes, what kind of cable should I use between the access point an
the modem (a “router to client cable” or a “peer-to-peer” cable)

Can I later add more wireless clients to the network withou
problems

Can the AP hand out ip adresses just like a router can
